Editing a car photo for a listing is a short job when you do it in the right order and a long one when you do it in the wrong order. Most of the time goes into fixing something twice: brightening a photo and then cropping away the part you brightened, or warming the color on one car and leaving the next one cold. The free editor already on your phone handles nearly all of it.
This post goes through the edits that make a listing photo better, in the order that saves you from redoing them, and then through the one category of edit you should never make to a car you are selling.
Pick the frames before you edit any of them
Choose the photos you will use before you open the editor. Delete the blurred frames, the near-duplicates, and the shots with a missing bumper or a person in the window, then check that the full walkaround is still there. Editing a frame you later throw away is the most common wasted time.
A phone makes it easy to shoot nine versions of the front three-quarter and none of the back seat. Lay the set out and look for both problems at once. Keep the sharpest frame of each angle and make sure every angle a buyer expects is covered: front and rear three-quarter, both sides, the dash, the odometer, the seats, the tires, and any wear. If an angle is missing or every version of it is soft, go back and reshoot it now. What a phone shot can and cannot recover is decided at the lot, and no edit brings back a wheel that was cut out of the frame.
Straighten before anything else
Level the photo first, because straightening crops the edges and changes everything you do after it. Find a line that should be horizontal, such as the roof of the building behind the car or the edge of the lot, and rotate until it is flat. Then check that light poles and door frames stand vertical.
A tilt of two or three degrees is enough to make a car look like it is parked on a hill, and buyers read it as carelessness even when they cannot say why. On an iPhone the Photos editor has a straighten slider under Crop, plus vertical and horizontal tilt for when you shot slightly up or down at the car. Google Photos has the same Straighten control in its crop tools. Do not use the car to judge level. Cars sit nose-down or tail-down on their suspension, and the ground on a lot is rarely flat. Use the building.
Fix the light, but keep the paint honest
Brighten the shadows before you touch overall exposure. The usual problem in a lot photo is a dark car under a bright sky: wheel wells and the interior go black while the paint looks fine. Lift the shadows until you can see the tire tread and the seat fabric, and stop before the paint turns flat and gray.
Leave the highlights alone unless the sky has gone white. A highlight on the hood that has already clipped to pure white has no detail left to bring back, so pulling the highlight slider down only turns it gray. If the photo is much too dark overall, raise exposure a little, but watch the brightest panel on the car. As soon as it loses its reflections it stops looking like paint.
Skip the one-tap filters and the saturation slider. Extra saturation makes a red car redder than it is, and the next section explains why that is a problem.
Make the color match the car in person
Correct the white balance so white looks white, because a buyer who drives an hour to see a red car expects the red in the photo. Fluorescent shop lights push photos green, shade and overcast skies push them blue, and warm bulbs push them orange. Fix the cast, then compare the paint against the car itself.
Adobe's guide to white balance describes the three casts you see on a lot: overcast light gives "a cold color temperature, more of a blue tone," incandescent light creates "a warm color cast" that shows up as yellow or orange, and "certain types of fluorescent lights can give your photos a green tint." The same guide warns that mixed light, such as a car half under a canopy and half in daylight, is hard to fix after the fact because one half of the photo is warm and the other is cold. That is a reason to move the car, not to work harder in the editor.
Before you save, hold the phone next to the car and compare. Silver and white cars show a cast the fastest, because any tint at all is obvious on a neutral color. Reds and dark blues are where an editor's warmth slider does the most damage, and they are also the colors buyers argue about at the lot.
Crop every photo to the same shape
Crop the whole set to one aspect ratio, and make 4:3 the default. Cars.com and Google vehicle ads both name 4:3, and a set that mixes ratios gets cut in different places by every site it lands on. Leave a little ground below the tires and a little air above the roof, and keep that margin the same on every car.
Cars.com's photo sizing guide asks for 4:3 on the vehicle detail page and warns that panorama-mode photos "can cause photos to appear cropped." Google's vehicle ads image rules recommend 4:3 as well, and go further: "Images which are truncated will be disapproved." A crop that clips a mirror or a bumper gets the ad rejected.
The crop is also where a set starts to look like one lot instead of thirty separate ads. The same angle and the same amount of car in the frame on every listing is most of what a consistent photo set says about your lot.
Clean up what is not the car
Remove distractions around the car, not on it. A traffic cone at the edge, a hose on the ground, or a stray price sign can come out with the retouch or object-removal tool, or with a slightly tighter crop. Anything bigger than a small object usually looks worse after a spot fix than before it.
Spot removal works on small things against plain ground, such as a cone on asphalt. It struggles with anything that crosses the car's outline, like a light pole growing out of the roof, because the tool has to invent the edge of the car. When the problem is the whole background, with other cars, the building, and the dumpster all in frame, removing pieces one by one leaves a smeared lot behind the car. That is a background replacement job, and it is the one LotReady exists for: it puts the car you photographed in a clean scene without repainting or reshaping the car. Whatever tool you use, zoom in on the edges afterward. The giveaways of a fake background are almost always at the tires, the mirrors, and the glass.
Leave the damage in
Never edit anything on the car itself. Scratches, dents, curb rash, worn tires, a cracked windshield, and seat wear stay in the photo. Remove one and the buyer finds it at the lot, and the sale turns into an argument about what else you changed. Edit the light, the color, and the background, and stop at the paint.
The Federal Trade Commission's pricing transparency FAQ puts the expectation plainly for used cars: "Because antique or used cars are rarely identical as they often differ in condition, it is reasonable for consumers to expect the photo to show the exact car offered for sale." A photo with the door ding painted out does not show the exact car offered for sale. The same goes for warming up faded paint, sharpening a bald tire, or cloning out a chip in the glass. Photograph wear clearly instead, in its own close-up. It makes the clean shots more believable, and it is the honest version of the listing. How to disclose an AI-edited photo covers where the line sits when a tool has changed the scene.
Export once, at the size the site wants
Save the finished photo once, from the original, as a JPEG in the sRGB color space at high quality. Every extra save of a JPEG throws a little more detail away, and the listing site will compress it again on upload. Aim for the long edge the site recommends rather than the largest file your phone can make.
Adobe's note on lossy compression is the reason to edit from the original and save once: "if you compress your images by too much or do so repeatedly, then you might see pixelation and loss of detail," and data discarded by lossy compression cannot be retrieved. Do not edit a photo you already downloaded from your own listing, and do not open, adjust, and re-save the same file through three different apps.
The sizes differ by site, so pick one master size that covers the ones you use. Cars.com recommends 640 × 480 for the vehicle detail page with a maximum of 1024 × 768. eBay recommends about 1600 × 1600, allows up to 24 pictures, and caps each file at 12 MB. Google's vehicle ads want at least 500 × 500 and recommend 1500 × 1500 or above. A 4:3 export around 1600 pixels on the long edge clears Google's minimum and comes close to eBay's recommendation. Cars.com accepts bigger files but warns they can take longer to process, so if most of your leads come from there, export at 1024 × 768.
Use sRGB for color. Newer phones can shoot in a wider color space, and WebKit, the engine behind Safari, assumes an image without a color profile is sRGB. A wide-gamut photo that loses its profile somewhere between your phone and the listing can show up duller or more saturated than what you saw on screen, so export in sRGB and keep the profile embedded.
Editing thirty cars instead of one
Edit the first car of the day carefully, then copy those settings to the rest. Cars shot in the same spot under the same light need nearly the same corrections, and copying them keeps the set consistent. Check each car afterward for color, because one preset will not fit a white car and a black one equally.
On an iPhone, the Photos app can copy the edits from one photo and paste them onto a batch of others: Copy Edits on the finished photo, then select the rest and Paste Edits. Desktop editors do the same with presets. Straightening and cropping still need a quick pass on each frame, because no two shots are tilted the same amount.
Work in the same order every time and the edits stop fighting each other:
- Pick the frames and reshoot anything missing.
- Straighten.
- Lift the shadows and check exposure.
- Correct the white balance against the real car.
- Crop to 4:3 with the same margins.
- Remove small distractions, or replace the whole background.
- Check that nothing on the car changed.
- Export once, in sRGB, at around 1600 pixels on the long edge.
