Gamma Correction

Gamma Correction gives you precise, real-time control over the colours in your photos. Using GPU-accelerated Canvas filters, adjustments happen instantly — no waiting, no rendering, no upload. Fine-tune brightness, contrast, saturation, hue rotation, colour temperature, tint, exposure, gamma and vibrance with intuitive sliders. Combine multiple adjustments in a single pass, save your favourite preset, and apply the same look to a whole batch of photos in one click.

Preset looks like sepia, grayscale, high-contrast black and white, cross-process, faded film, teal-and-orange, warm sunset, cool blue hour and vintage are one tap away. Each preset is a starting point you can tweak further — nothing is locked. The colour picker tool inside also lets you sample any pixel in your image to grab its HEX, RGB or HSL value for design work.

Popular use cases include: matching product photos to a consistent visual style across an e-commerce catalogue, rescuing under-exposed photos taken indoors, prepping food photos for a restaurant menu, applying a signature look across a personal Instagram feed, matching brand colours in marketing images, converting photos to black-and-white for print, and identifying dominant colours in artwork for palette references.

All processing is client-side. Your original photo stays untouched — you always download a new file — and nothing is uploaded to any server. There's no signup, no watermark, no cap, and no ads on the output.
