## What is Photo Curves?

Photo Curves is a color grading app for photos and videos. Correct, enhance or replace colors, shift HUE, fix white balance or create cinematic orange and teal look, create 3D LUTs or presets library, resize images, and more.

Create custom filters instead of searching through hundreds of predefined LUTs. Photo Curves comes with example presets, which are fully editable using RGB, CMYK, LAB, HSL curves, color wheels, and other tools. 

List of tools:

- Basic controls (brightness, contrast, shadows, highlights, saturation)
- Color wheels (shadows, midtones, highlights)
- RGB curves
- CMYK curves
- Lab curves
- Hue vs Saturation curve
- Hue vs Hue curve
- Hue vs Luma (Lightness) curve
- Luma vs Saturation curve
- Luma vs Hue curve
- Saturation vs Saturation curve
- Masking tool with independent adjustment layers

Export your color grading presets as 3DLUT (.cube files) or save them to your presets library. You can use build-in presets/filters as is or as a starting point for your color grading experiment. Remember - every preset is fully editable!

Presets library:

- Create your own presets or edit existing
- Export your presets to a file and share or import presets created by others
- Export presets as 3DLUT (.cube files)
- Built in library includes pre-defined presets, including popular Orange Teal and other artistic filters.

Color grading hints:

Color wheels - adjust colors of shadows, midtones, and highlights.

RGB/CMYK curves - play with Red/Green/Blue or Cyan/Magenta/Yellow/Key color channels.

LAB curves - LAB color space gives you yet another level of creative freedom.

Hue vs Saturation curve - make one color more vibrant than others, or turn the entire image black and white while preserving one color only.

Hue vs Hue curve - selective hue shift; i.e. adjust the color of the blue sky or green grass to dramatically change the mood of your photos.

Hue vs Luma curve - selective brightness control of a specific color or color range.

Luma vs Saturation curve - adjust saturation of shades, midtones, or highlights.

Luma vs Hue curve - shift hue of shades, midtones, or highlights.

### 5/5 — Absolute value for money

*2026-02-10, version 1.2.32*

Nifty little app for hobby photographers who want to dabble with colors in their photos. For the price it is an absolute gem.

### 5/5 — RGB CURVES!

*2024-09-28*

Without a doubt, this is by far one of the greatest color grading apps you can find and it’s well worth the small purchases to get the whole thing. I recently left Adobe and desperately needed a replacement for Lightroom. When I stumbled upon this I was shocked with how well the curves tool worked (highly underrated and barely found on most popular photo editing apps). Although there are a few UI issues that I hope can be updated to be a little more intuitive, this is still my go to app for editing. This shouldn’t be this cheap but I’m glad it is. Thank you!

### 1/5 — 4k export not working

*2023-04-21, version 1.2.23*

When I tried to export in 100% quality i got only 1280*720.  I have mailed about this issue but no one’s replied.

### 5/5 — Quick and Easy to use

*2023-02-04*

This app is fantastic! It’s simple to use, and makes my videos turn out great! 10/10

### 5/5 — Good color grading app for mobile

*2022-09-24*

I'm a beginner to color grading and just wanted to play around with it a bit, and this had pretty much all the tools I needed to do so. Very good, free except for one feature, but even so you can still do a lot with it.
