iPhone Colors AlTaglio, change the colors of your photos without altering their tonal range

[Roger Tallada]

Hi!

I'm the developer of Colors AlTaglio, the iOS 9 Photos extension that allows editing the colors of a photo using gamut masks. Gamut masking is a technique used by painters to create color palettes that lets you define the range of colors available by selecting an area of the color wheel.

Since it works with the HUSL colorspace it can modify the hues of an image without altering its perceptual lightness, thus preserving the original tonal range. It's the first photo processing app that works with this colorspace and the first one that lets you apply a gamut mask to a photo.

Colors AlTaglio Features:

- Change the colors of your photos using gamut masks.
- Preserve the contrast and tonal range of your images after every edit.
- Set the neutral color of the gamut mask.
- Change the hues of an image by rotating the color wheel.
- Immediately preview your changes thanks to the filter being implemented in Metal.
- Colors AlTaglio is an iOS Photos extension so it's easy to add to your workflows.

Requirements

Colors AlTaglio requires iOS 9.1 and an iPhone or iPod Touch with a 64-bit processor.
