Brightness and contrast — Delivery workflow

Worked example

Keep an untouched master, send copies named with an adjust suffix, and write down your slider values so the next batch matches.

A potter listing twelve products online needs the photos to look like one collection. Pick the best-exposed shot, find values for it (say Brightness 125, Contrast 108, Shadows 25), then open each other photo and judge it separately, starting from those numbers. The edit queue holds up to 12 images and 48 MB, and when two or more finished results are ready a ZIP named adjust-results.zip contains them with numbered names.

Mind the sequence. Adjust tone after rotating or cropping and before resizing or compressing, since sharpening or compressing first would bake artifacts into pixels you then brighten. The output keeps the source format at 92% quality, so a JPG that was 2.2 MB usually returns at a similar size.

Platforms have their own rules for dimensions, file size and colour handling, so check the current upload guide before you publish. Do not rely on a shop to correct tones for you; a slightly brighter, calmer photo usually survives their re-compression better than an extreme one.

The common mistake is overwriting the original or applying the same numbers to every photo. Keep masters in one folder and adjusted copies in another, and compare each pair side by side. For customers, consistency of light and background matters more than any single dramatic edit.

Record your slider values for the batch, because the tool does not remember them after you close the page.
