Image Adjustment: tweak brightness, contrast, and color across a batch

Adjusts the look of every image in your batch — brightness, contrast, color channels, saturation, vibrance, and hue. Eight sliders, one consistent result.

Image Adjustment is your batch-level color correction tool. Eight sliders to fix lighting, color cast, and saturation across every image at once.

If your batch of source images came out at slightly inconsistent brightness or color — different mockup tools, different stock libraries, different AI generations — this is the tool that brings them in line.

Why this step matters

Even carefully-sourced batches end up inconsistent — different generations, different mockup exports, different stock libraries each have their own brightness and color bias. For Etsy listings or print-on-demand where consistency matters, you want the whole batch to look like one shop, not 40 different sources.

Image Adjustment applies the same correction to every image, so they all end up in the same visual range.

How to use it

Add Image Adjustment to your pipeline.
Move the sliders to taste. Watch the live preview — it shows your first image being adjusted in real time.
When the preview looks right, run the pipeline. Every image in the batch gets the same treatment.

The sliders

All sliders default to 0 (no change). Negative values reduce; positive values increase.

Slider	Range	What it does
Brightness	−100 to +100	Makes the image lighter (positive) or darker (negative).
Contrast	−100 to +100	Punches the difference between light and dark areas (positive) or flattens it (negative).
Saturation	−100 to +100	Strengthens (positive) or weakens (negative) ALL the colors at once. −100 = black and white.
Vibrance	−100 to +100	Like Saturation, but smarter — boosts muted colors more than already-bright ones. Less likely to make skin tones look weird.
Hue	−180 to +180	Shifts every color around the color wheel. Reds become greens, etc. Use sparingly — small shifts (5–15) for white-balance fixes; big shifts for creative recoloring.
Red	−100 to +100	Strengthens or weakens just the red channel. Useful for warming/cooling images.
Green	−100 to +100	Same for green.
Blue	−100 to +100	Same for blue. Often used to fix blue color casts from fluorescent light.

Common adjustments

Goal	Settings to try
Images look slightly washed out	Contrast +15, Saturation +10
Images look too dark	Brightness +15, Contrast +5
Images have a yellow/warm cast	Blue +10, Red −5
Images have a cold/blue cast	Red +10, Blue −10
Want a vintage / muted look	Saturation −25, Contrast +10
Want punchier social-media colors	Saturation +15, Vibrance +20, Contrast +10
Convert batch to black and white	Saturation −100

Tips

Start small. Big slider moves are rarely right. ±10 is usually enough to shift the look meaningfully.
Vibrance > Saturation for most product images — Vibrance keeps skin tones natural while still boosting product colors.
Watch the preview, not the numbers. What looks "+30 brightness" on one batch might be too much on another.
For batches with very different content (some bright, some dark), Image Adjustment will shift them all by the same amount — so the bright ones get more bright and the dark ones get more dark. If your batch needs different corrections per image, separate them.
Combine with Filters. Use Image Adjustment for normal correction, then a Filter (Sharpen, Vignette) for creative touches.

Things Image Adjustment doesn't do

It doesn't auto-correct. No "auto white balance" or "auto brightness" button — you set the sliders manually.
It doesn't fix per-image differences. The same correction applies to every image in the batch. If image 1 needs +10 brightness and image 2 needs −10, this isn't the right tool.
It doesn't replace selective edits. Brightness and contrast affect the whole image. To brighten just a face or just a background, you'd need a different image editor.
It doesn't change the image's size, shape, or transparency. Pure color and tone work — no geometry.
