If you solder 0603 parts, rework QFN packages or repair phone boards, the microscope is not a luxury item any more. It is the difference between placing a component squarely on its pads and guessing.
Short version: the TOMLOV DM9 is the best digital microscope for soldering overall, because its metal base and 8.5 inch stand stay put while you work and its lighting can be angled to kill glare off shiny solder. The Andonstar AD249S-M carries the highest average rating in this group and pairs it with a 10.1-inch screen. If you have a spare monitor on your desk, the Plugable USB 250X costs almost nothing and simply appears as a webcam.
Do you need a microscope to solder? Not for through-hole joints and hookup wire. The moment you move to surface-mount work, the components get smaller than your unaided eye can resolve, and inspection becomes valuable even on jobs you could do without looking. Most people also report less eye strain once they are watching a screen instead of leaning over a board.
Several of these also pass video or stills to a PC. One clamps to your bench and needs nothing else. The differences that matter are stand rigidity, lighting and output options, not the headline magnification number, which is where most buyers go wrong.

1. TOMLOV DM9 7-Inch Digital Microscope – the steadiest all-rounder
TOMLOV DM9 7″ Digital Microscope: 1080P 1200X Coin Microscope Magnifier, 12MP Ultra-Precise Focusing LCD Soldering Microscopes for Adults, PC View, 16GB
1200X max magnification
7-inch LCD screen
12MP stills and 1080P video
Metal base with 8.5 inch stand
Pros
- Metal base and stand stay steady during hands-on work
- 8 built-in LEDs plus 2 gooseneck lights
- 7-inch LCD avoids leaning and squinting
- 12MP camera with included 16GB card
- Connects to Windows and Mac PCs
Cons
- 7-inch screen is smaller than most competitors
- Features lean toward coin collecting over repair functions
We put the DM9 at the top of this roundup because the stand, not the camera, is what decides whether a scope is pleasant to solder with. The base is solid metal and the post measures 8.5 inches, so when you lean the board toward the lens the frame does not creep across the bench.
At 1200X advertised magnification, the useful range sits much closer to the 30X to 50X mark on the built-in display, which is the window you will live in for 0603 and 0402 parts. Focus is manual through a wheel, and height adjustment is manual too, so nothing hunts while you reposition a board.
The lighting is where this model earns its place. Eight LEDs ring the lens and two gooseneck arms let you throw light in from a low side angle, which is the only reliable way to see the surface of a shiny joint instead of its reflection. Dimming is on the host, so you can drop intensity when a bright pad washes out.
Capture is a 12MP still sensor with 1080P video and a 16GB card in the box, so documenting a repair does not need a separate purchase. PC connection works on Windows and Mac if you would rather view on a larger display.
What works well at the bench
Because the arm and post are metal and reasonably heavy, an accidental knock from a soldering iron handle does not shift the frame. That matters more than raw resolution when you are working on something you cannot afford to redo.
The gooseneck lights also solve the shadow problem. A board-level camera mounted under the lens throws a shadow of your own tweezers across every pad, and moving the light out to the side removes most of it.
Where it falls short
The 7-inch display is the smallest of the screen-equipped models in this roundup apart from the clamp-mounted unit below it. If your eyesight is not what it was, you will spend more time squinting and less time working.
This is also marketed as a coin microscope first, and the software and stand proportions follow that framing. It does everything we need for solder joint inspection, but a purpose-built repair scope shows more intent in its layout.
2. Aikokkl 5-Inch C-Clamp Microscope – clears the bench
Aikokkl 5″ LCD Digital Soldering Microscope for PCB Repair with C-Clamp
Up to 1000X digital magnification
5-inch IPS screen
C-clamp with flexible goose-neck arm
Battery powered
Pros
- C-clamp mount frees the whole bench surface
- No drivers or third-party software needed for PC view
- Battery powered for untethered sessions
- Metal construction suits a compact clamp workspace
Cons
- No autofocus and the micro SD card is not included
- Smallest screen in this roundup at 5 inches
- Sharpness depends on arm distance plus manual wheel
The idea here is simple and we like it. Instead of a base plate sitting on your work surface, this scope clamps to the edge of the bench with a C-clamp and a flexible goose-neck arm. That keeps the entire area in front of you clear for a mat, a parts tray and your iron hand.
Magnification is listed as up to 1000X digital and it is achieved by changing lens-to-object distance, then turning a silver focus wheel until the image sharpens. There is no autofocus, and the manufacturer is upfront about that rather than hiding it behind a claim.
The PC view is the sleeper feature. Selecting the PC camera mode makes the device show up as an ordinary camera, so Windows users open the built-in Camera app and Mac users open Photo Booth, with no driver downloads and no bundled third-party utility to go wrong.
It is battery powered, weighs 1.2 pounds and measures just over 2 inches thick, so it moves between a bench and a field repair kit easily. Saving photos and 1080P video needs a micro SD card up to 32GB, which is not included.
Best for a cramped or shared bench
If your bench already has a soldering station, a parts drawer and a laptop taking up space, a clamp-mounted scope solves a problem no base-plate model can. Nothing occupies the surface you work on.
The no-software PC mode also makes this a safe first microscope. One PedalPCB poster described avoiding Amazon specials because they seemed to require shady software, and this model sidesteps that problem entirely by using the operating system you already have.
Where it falls short
A 5-inch IPS panel is for micro-detail work only. Holding a whole board in view while still reading a joint clearly is not realistic, so expect to move the board rather than the scope.
Manual focusing plus a small screen means more fiddly repositioning than a larger unit with a rigid post. For long sessions or larger boards, spend a little more for a bigger screen and a steadier frame.
3. Andonstar AD246S-M 3 Lens 2160P – multi-lens flexibility
Andonstar AD246S-M 3 Lens 2160P HDMI Digital Microscope 2000x for Adults
Three lenses for soldering, coins and slides
2160P UHD video
HDMI output to a larger monitor
Pro metal boom arm stand
Pros
- Three interchangeable lenses cover several jobs
- 2160P video with HDMI out for a big view
- Strong metal boom arm adjustable in all directions
- Windows measurement software for length and area
- Wireless remote plus 8 LED brightness levels
Cons
- Lens changes require removing and reinstalling screws
- Fully manual focus with no autofocus
- Cable power only with no battery option
This is the one to buy if electronics work is only part of what you inspect. Three lenses ship in the box: one for soldering and board repair, one for larger whole objects, and one for slides. You are not paying three times for the privilege of the right lens at the moment you need it.
Video is 2160P UHD and the unit carries HDMI output, so the 7-inch screen is optional. Feed the signal to a 28-inch monitor with 3X digital zoom and the headline figure on the solder lens climbs from the on-screen range toward the top of the 2040X claim.
The pro boom arm is a genuine metal bracket measuring roughly 7 by 7.8 by 13 inches, adjustable front to back, side to side and in angle. The listing describes the metal as suitable for high-temperature environments such as soldering, and in practice the arm stays put near a hot work area.
Connect it to a Windows PC and the measurement software handles length and area calculations alongside photo and video capture. A wireless remote lets you trigger captures without touching the head, and a 32GB card is included.
When the multi-lens approach pays off
Board repair, coin inspection and mounting a prepared slide in the same week is a normal week for many technicians. Having the lens already in the box removes the temptation to buy a second scope for a different task.
The measurement software is the other quiet win. When a pad is supposed to be 0.5 millimetres wide and it is not, a measurement readout settles the argument faster than a squint through an eyepiece.
Where it falls short
Swapping lenses means removing and reinstalling screws, which is a genuinely fiddly two-minute job in the middle of a task. Plan your lens before you start a rework rather than halfway through a hot joint.
Focus is entirely manual through a wheel plus a bracket knob, and the unit runs on cable power with no battery. If you move between benches often, or you want autofocus, this is not the one.
4. Elikliv EM4K-AF Autofocus 4K – 8-inch screen with AI focus
Elikliv Autofocus 4K Digital Microscope EM4K-AF, 8″ Soldering Microscopes
AI autofocus with TOF distance sensor
4K UHD video and 52MP stills
8-inch 1280x800 IPS screen
Rechargeable internal battery
Pros
- Autofocus refocuses in about 2 seconds on moving hands
- 4K video and 52MP image capture
- Freeze and split-screen modes for before and after comparison
- HDMI and USB output to a larger monitor
- Rechargeable battery with 16GB card and controller
Cons
- 10-inch post and broad base use more bench footprint
- Autofocus still needs manual fine-tuning on reflective surfaces
This one answers the question every autofocus microscope listing dodges: does it actually help while you solder? The EM4K-AF uses a time-of-flight distance sensor and AI logic that continuously judges image clarity, with a focal adjustment in roughly 2 seconds, and reviewers report it holding a joint sharp while their hand is still moving.
Capture numbers sit at the top of this roundup. Video records at 3840 by 2160 and stills at 9600 by 5400, with an 8-inch 1280 by 800 IPS panel at a 178-degree viewing angle in front of you.
The freeze and split-screen modes are more useful for repair work than they sound. Freeze locks a joint on screen so you can compare it against a second view, and split-screen places two samples beside each other, which is a fast way to judge a rework against a known good board.
Output covers both HDMI and USB, so it works as a standalone unit or drives a larger monitor for long inspection sessions. The internal battery is rechargeable, which suits field repair work where there is no bench to plug into.
When autofocus earns its price
Autofocus matters most when your hand is not still: dragging a fine tip across a pad, dragging solder wick across a bridged row, or working under a board where you cannot see your own fingertips. In those situations, repeated manual wheel work costs more than it saves.
Freeze mode also changes the workflow. Rather than describe a defect to a client, you capture it, show it and mark it before you touch the board.
Where it falls short
The 10-inch post and broad base take up noticeably more bench surface than a clamp-mounted model, and that footprint is the price of the stable platform the autofocus depends on.
On very uneven or highly reflective surfaces, such as a freshly reworked connector or a mirror-finish shield, autofocus still asks for a manual correction. Two seconds is quick, not instant.
5. TOMLOV TM4K-AF Flex – autofocus with preset focus points
TOMLOV Autofocus 4K Digital Microscope, 8″ TM4K-AF Flex Arm for Soldering
AI autofocus with TOF sensor
Preset focus points P1 and P2
4K UHD video and 52MP stills
360 degree articulating flex arm
Pros
- Preset focus points switch quickly on uneven surfaces
- 8-inch 1280x800 IPS panel with 100 percent sRGB colour
- Articulating flex arm with rail and fine adjustment knob
- Soldering mat
- remote and light barrier included
- Manual focus available as a fallback
Cons
- Head unit and mount feel like cheap plastic
- HDMI output is 1080p rather than 4K
- PC mode disables menu
- zoom and recording controls
The P1 and P2 focus presets are the cleverest feature in this roundup. Set one focus point on a flat area of the board and one on a raised component, then switch between them instantly instead of re-hunting with the wheel each time you move across the panel.
Autofocus itself uses a time-of-flight sensor with AI adaptation to moving subjects, and manual focus remains available when autofocus struggles. Colour accuracy is rated at 100 percent sRGB, which matters when you are judging whether a component is the right part or a joint is properly wetted.
The 360-degree articulating arm comes with a rail and a fine up-down adjustment knob, so you can park the head out of the way and bring it back to the same spot later. A soldering mat, remote control and light barrier are all in the box, which saves a separate purchase.
This sits at the top of the price range in this roundup, and it competes with rigid post stands on comfort and reach rather than on stability. Reviewers tend to judge it in those terms once they have seen the articulating arm in use.
What works well in practice
Folding the arm away is genuinely useful when you are dragging solder wick or reaching for a hot air gun. A rigid post is more stable but permanently occupies the space above your mat.
The preset focus points turn autofocus from a gimmick into a repeatable habit, particularly on double-sided boards where one side sits a few millimetres higher than the other.
Where it falls short
Be honest about the build. Reviewers repeatedly describe the head unit and mount as feeling like cheap plastic despite the metal arm, and this model carries the lowest average rating in the roundup at 4.2.
Two specific limits are worth knowing before you buy. The HDMI output is 1080p rather than the 4K the sensor records, and PC-connected mode disables the menu, zoom and recording controls, which removes several tools while you have them in front of you.
6. Andonstar AD249S-M 10.1-Inch – the best rated, on a large screen
Andonstar AD249S-M 3 Lens 2160P 10.1 Inch HDMI Digital Microscope 2000x
10.1-inch LCD display
Three lenses for soldering, coins and slides
2160P UHD video
HDMI output to an external monitor
Pros
- Highest average rating in this roundup at 4.6
- 10.1-inch screen shows a whole board and fine detail
- Three lenses including a long working distance solder lens
- Dual adjustable LED lights reduce glare
- Measurement software plus 32GB card and remote included
Cons
- Base work surface is small relative to the advertised size
- Stand feels lighter and more plastic than the cost suggests
- Post may arrive slightly tilted and need levelling
The AD249S-M is the same three-lens platform as the model above with a larger 10.1-inch display instead of 7 inches, and it holds the highest average rating in this roundup at 4.6 across 451 reviews with 77 percent of ratings at five stars.
Screen size is not a vanity spec here. A 10.1-inch panel lets you frame a whole mobile motherboard and still resolve a pad without repositioning, which cuts the constant head movement that comes with a small display.
The solder lens is specified for 15X to 60X on screen and up to 60X to 240X on HDMI output with 3X digital zoom, alongside lenses for whole objects and slides. That 15X to 60X band covers 0402, 0603 and most QFN work without resorting to extreme digital zoom.
Dual adjustable LED lights at eight intensity levels are the practical feature we would keep, since they let you dial out the reflection off a shielded can or a fresh solder bead. The pro boom arm bracket adjusts in every direction and is described as metal for high-temperature environments.
Why the 4.6 rating matters
Reviewers repeatedly compare this display favourably against far more expensive binocular soldering scopes, citing the clear image, adjustable dual lighting and solid metal construction. Only 2 percent of ratings are one star, which is unusually low for the category.
For board-level phone and laptop repair, the combination of a large screen and a long working distance lens is the configuration most technicians end up wanting.
Where it falls short
The most repeated caveat is the base work surface. Owners note it is small relative to the advertised footprint, which limits larger boards, and some stabilise it by mounting the stand to a heavier surface such as granite.
Focus is manual and lenses still swap with screws. The post can also arrive slightly tilted and need levelling before the first job.
7. TOMLOV DM9 Max – ten lights and a tall stand on a mid-range budget
TOMLOV DM9 Max Digital Microscope: 20MP 10.1″ 1500X HD IPS Coin Microscope Magnifier for Error Coins with Screen, LCD Soldering Microscopes for Adults, 10 LED Lights, PC/TV Compatible, 16GB
10.1-inch IPS display
5X to 1500X advertised zoom range
Up to 20MP photos and 1080P video
12.6 inch stand with 7 by 8 inch base
Pros
- One of the largest screens here at 10.1 inches
- Ten dimmable lights: eight around the lens plus two gooseneck
- Tall 12.6 inch stand gives real room over a board
- Remote adds extra zoom and avoids shaking the view
- Two year manufacturer warranty
Cons
- Advertised 1500X is largely digital zoom
- Focusing mechanism and post feel cheaply made
- Screen can wobble even with the grub screw tightened
For the money, this is the most generously equipped scope we tested. A 10.1-inch IPS panel with a 178-degree viewing angle, a 12.6-inch stand on a 7 by 8 inch base, ten lights and a wireless remote, plus a two-year manufacturer warranty that doubles what some rivals offer.
The lighting arrangement is the standout: eight dimmable LEDs around the lens plus two gooseneck side lights. That combination lets you set a low key light to model a joint and use the ring as fill, which is how you get a readable image of anything shiny.
Photo resolution options step from 2MP up to 20MP at 6096 by 3424, with 1080P video and a noise reduction chip plus an ultra-sensitive microphone for recording a repair with narration.
The remote is worth more than it sounds. Zoom, photo capture and video start all happen from the controller, so nothing touches the stand and the image does not shift mid-task. It connects to a PC or a TV for a larger view.
Where the value actually sits
Compared with the models above it, you give up the multi-lens kit, the boom arm and the autofocus. You do not give up screen size, lighting control or working room over the board, and those three matter most for soldering.
The two-year manufacturer warranty is worth noting too, since you will be working a hot iron near a plastic post.
Where it falls short
The magnification claim needs handling carefully. A reviewer with 45 years of microscopy experience measured roughly 45X true magnification on the included screen and called the 1500X figure misleading, while still rating the scope four stars. Judge it on the lens and the screen, not the number.
Build quality is the other weak point. The focusing mechanism and post feel cheaply made, the screen can wobble on the stand even with the grub screw tightened, and the base light battery has been reported to stop charging after a few months.
8. Plugable USB 250X – the laptop microscope
Plugable USB Digital Microscope 250x, 2MP Micro Camera, Flexible Arm Stand
2.0 megapixel sensor
60X to 250X magnification
USB and USB-C connectivity
LED halo light with brightness control
Pros
- Works as a standard webcam on Windows
- Mac
- ChromeOS and Linux
- Longest review history in this roundup at 6579 reviews
- Weighs 2.9 ounces with a flexible arm and observation pad
- LED halo at 7000K with brightness control
- Two year limited warranty with lifetime support
Cons
- No built-in screen so you need a laptop
- tablet or monitor
- 250X ceiling is well below the other models here
- Plastic body and a 45 degree field of view
- Light stand gives less rigidity for long sessions
Nothing else in this roundup has a review history like the Plugable. More than 6,500 ratings at a 4.2 average is a decade of accumulated owner experience, and the design choice explains both the rating and the longevity: it uses a webcam chipset and presents itself as a standard camera.
Because it registers as a webcam, it works with whatever software you already use on Windows, Mac, ChromeOS or Linux, with connectors for USB and USB-C. There is no proprietary application to install or keep updated.
Magnification runs 60X to 250X on a 2.0 megapixel sensor, with an LED halo light at 7000K and a brightness control from 0 to 38 lumens. The whole body weighs 2.9 ounces and the head measures 3.5 inches long, so it packs into a tool bag.
The flexible arm and observation pad are included, and you can also use it handheld for quick looks before committing to a bench setup.
When a cheap USB microscope is the right answer
Inspection jobs. Checking a cold joint, a cracked via or a lifted pad before you start work does not need 2000X and a large display. This covers those checks on any laptop you already own, including a Chromebook at a repair counter.
It is also the only travel-friendly option here, at 2.9 ounces with no separate screen, cable management or stand footprint to worry about.
Where it falls short
The 250X ceiling is the hard limit. Once you are past basic inspection and into placing 0402 parts, you will want a scope with a real optical lens and a bigger view.
There is no built-in screen, so the laptop or monitor has to travel with the microscope. The plastic body and 45-degree field of view also limit fine detail, and the light stand offers little rigidity for a long soldering session.
How Much Magnification Do You Actually Need?
Start from the package on your board, not from the listing. The number that matters is the useful band at the screen, which for these scopes sits far below the advertised maximum.
0402 and 0603 passives: roughly 20X to 45X on screen is comfortable. Above that, field of view shrinks faster than detail improves and you spend more time moving the board than inspecting the joint.
0805 and 1206 plus through-hole: 10X to 20X is plenty, and this is the range where a USB microscope still does a respectable job.
QFN and QFP fine-pitch: 40X to 80X, with side lighting, is where a proper soldering lens starts to earn its cost.
BGA lands and pad arrays: 60X to 120X plus the ability to reframe without losing your place.
The correction worth remembering: advertised 1000X to 2040X figures include digital upscaling. That does not add detail, it stretches pixels. One experienced reviewer measured about 45X true magnification on a scope advertised at 1500X, and still considered it a useful tool, because the real driver of a good image is the lens, the sensor and the lighting.
Whatever you buy, confirm the output can be flipped and rotated so the image is not mirrored. A PedalPCB poster described rotate-and-flip support as essential rather than a nice-to-have, and he is right: if moving your hand in one direction moves the image the other way, your fine motor control has to fight the display on every joint.
Digital vs Stereo Microscopes: An Honest Comparison
A digital microscope gives you a bright, comfortable, high-resolution image and lets you photograph the joint. It also takes away depth perception and puts your hands and your eyes in different places, which is a real cost that spec sheets never mention.
A PedalPCB user named vigilante398 put it plainly: he could never get the hang of soldering without looking at his hands, so he could not get used to the digital microscope he tried. Another poster, Alan W, said depth perception using both eyes seemed to be a big part of it, particularly on dense boards and 0603 parts.
There is a counterpoint worth hearing too. A buyer who started with a mid-priced digital scope concluded the camera side of the job was handled well, while wishing for a spring-loaded flex arm, and expected it to retire his binocular scopes around the bench.
So the honest split is this. If your work is inspection heavy, documentation heavy or involves boards you cannot physically bring to your eyes, digital wins on comfort and reach. If your work is placement heavy on small parts and you already have the hand-eye coordination to do it unaided, a binocular stereo microscope remains more precise because your eyes stay on the work.
One PedalPCB owner running an AmScope SE400-Z on a boom arm with a gooseneck LED reports no complaints after four years of SMD soldering, trace modification and general board inspection. That is the standard digital units are measured against, and the shortest way to understand the gap is to try a stereo scope at a local electronics supplier before committing to a digital one. If you are still working out what magnification suits your parts, our microscope guide for students covers the simpler optical options.
If you are still choosing tools, our guide to the best soldering irons and the best soldering stations covers the tools that work alongside whatever scope you choose.
How to Set Up Your Microscope for Soldering
Most disappointing microscope results come down to setup rather than hardware. Five steps, about ten minutes.
1. Park the head, not the board. Position the lens 4 to 6 inches above the work area so an iron can enter at an angle without touching the head or the arm.
2. Kill the glare first. Start with the ring light low or off and use the side lights. Move them in small steps until the joint has a visible fillet rather than a white highlight.
3. Focus on something solid. Set focus on the board surface or a large pad, not on the component you are about to place. Small parts will not be the reference.
4. Set exposure before you work. Bright pads next to dark solder will make the camera hunt its brightness. Lock exposure on the board so the image stays stable as you move across it.
5. Place the screen where your eyes already are. Position the display just below your natural eye line and roughly where your hands are, so you are not tilting your head back or craning forward.
Add a heat-resistant mat under the work area and keep the iron in its holder between joints. It keeps the board from sliding, which is the other common cause of a blurred image. If you also work on jewellery or metalwork, our jeweller’s soldering kits guide covers the different heat demands of that work.
Frequently Asked Questions
What magnification is good for soldering?
For 0402 and 0603 components, roughly 20X to 45X on the screen is the comfortable range. QFN and QFP fine-pitch work sits around 40X to 80X, and BGA pad inspection around 60X to 120X. Ignore the advertised 1000X-plus figures on most listings, because those include digital upscaling rather than real optical magnification. Judge the scope by its lens, sensor and lighting instead.
Do you need a microscope to solder?
Not for through-hole joints or hookup wire, where your unaided eye is already sufficient. Once you move to surface-mount parts, components become smaller than you can resolve, and a microscope prevents lifted pads and solder bridges. Even if you can solder without one, it is valuable for inspection, and most users report less eye strain over long sessions once they are watching a screen.
Is Swift or AmScope better?
Both are stereo optical microscope brands rather than digital ones, so that comparison mostly helps if you are deciding whether to leave the digital category. AmScope covers a wide entry to professional range and is the name most often recommended on electronics forums. For a simpler starter option, our guide to the best microscopes for students covers what you can get before committing to a bench instrument.
What digital microscope is best for electronic repair?
The TOMLOV DM9 is our best overall pick, because its metal base and 8.5 inch stand stay steady while the eight built-in LEDs plus two gooseneck lights let you angle light away from glare. The Andonstar AD249S-M offers the largest screen at 10.1 inches and the highest average rating in this group, while the TOMLOV DM9 Max gives you the biggest screen and most lights for the least money.
What is the difference between HDMI and USB microscopes?
A USB microscope registers as a standard webcam, so it works with whatever software you already have on any platform and needs no bundled application. An HDMI scope sends a direct video signal to a second monitor, which gives a larger, cleaner view with no extra software between the sensor and the screen. If you already have monitors on your desk, HDMI is the better long-term choice for soldering.
Final Verdict
After working through all eight, the TOMLOV DM9 is still the best digital microscope for soldering in 2026 for most people, because a stable metal stand and aimable lighting solve the two problems that actually ruin board work. It has the deepest review history of the screen-equipped models here and no glaring weaknesses beyond a 7-inch panel that some buyers wish were larger.
Buy the Andonstar AD249S-M if you work on whole phone boards and want one large screen that shows the board and the joint without constant reframing. Choose the TOMLOV DM9 Max if you want the biggest screen and the most lighting for the least money, and can accept the plastic feel of the post. Pick the TOMLOV TM4K-AF Flex if you want autofocus and preset focus points and can live with 1080p HDMI output.
Choose the Aikokkl 5-inch when your bench has no free surface, and the Plugable USB 250X when you just need portable inspection on a laptop you already own. Whichever you pick, set the working distance first and the lighting second, and check that the image can be flipped so it is not mirrored.
