Photo Curves - Custom Color Grading & Filters

Photo Curves is a color grading application designed for both photographs and videos. It allows you to generate your own filters rather than sifting through numerous applications with fixed presets that cannot be adjusted. Each preset in Photo Curves can be fully customized. You can also craft your own presets using versatile color grading features. This application enables you to correct, enhance, or swap colors, modify Hue, adjust white balance, create cinematic Orange and Teal aesthetics, produce 3DLUT files, resize images, alter JPEG quality, and much more.

The current tools include:

- Essential 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

- Adjustment layers

You can export your color grading work as a 3DLUT (.cube) file or save it to your preset library for future use or sharing purposes. Built-in presets (filters) can be used directly or as a basis for your subsequent color grading projects. Remember that every preset is entirely modifiable!

Preset library functions include:

- Develop your own presets or make alterations to existing ones

- Export your presets to a file for sharing or import presets made by others

- Export presets in the form of 3DLUT (.cube) files

- The library also contains standard predefined presets, including popular Orange Teal and various artistic filters

Here are some color grading tips:

Basic Controls - manage brightness, contrast, shadows, highlights, and saturation.

Color Wheels - blend a color into the shadows, midtones, or highlights of an image.

Layer Masks - create adjustment layers and draw masks to apply color grading adjustments to specific areas of an image.

RGB curves - independently manipulate red, green, and blue channels.

CMYK curves - control the cyan, magenta, yellow, and key channels within the CMYK color space.

LAB curves - modify the brightness (L) along with A and B color channels specific to the LAB color space. Unlike RGB, the LAB color channels do not influence the brightness component, allowing for more imaginative color adjustments.

Hue vs Saturation curve - alter the saturation for a color or a specific HUE range.

Hue vs Hue curve - selectively shift colors by changing the HUE.

Hue vs Luma curve - adjust the brightness of a particular color or HUE range.

Luma vs Saturation curve - modify the saturation of dark shades, midtones, and highlights.

Luma vs Hue curve - change the HUE of different shades, midtones, or highlights.

Saturation vs Saturation curve - amplify unsaturated colors while decreasing overly saturated hues to achieve evenly saturated HDR-like imagery.

A Colorist's Revolution: Precision Grading at Your Fingertips

Photo Curves has utterly transformed my creative workflow, replacing cookie-cutter presets with granular, artistic control that makes every image and video feel authentically mine. As a photographer and videographer, I’ve spent years frustrated by apps offering rigid filters—until this tool handed me the keys to a colorist’s studio. The sheer depth of its curve-based editing is breathtaking: from subtly tweaking LAB lightness channels to crafting cinematic orange-and-teal contrasts or rebalancing shadows via CMYK wheels, this app doesn’t just edit colors—it redefines them. I vividly remember rescuing a murky sunset shot by precisely dialing in the Hue vs Luma curve, isolating golden tones while deepening blues, all without artificial HDR harshness.

What sets Photo Curves apart is its dual genius: it’s both a playground for experimentation and a precision instrument. The masking tools and adjustment layers let me dodge/burn skin tones independently from backgrounds, while custom presets empower me to save nuanced looks—moody forest palettes, vibrant street scenes—and export them as reusable 3DLUT files (.cube) for cross-platform consistency. Even "basic" sliders like Highlights/Shadows feel surgical, and features like Saturation vs Saturation curves masterfully tame oversaturated skies while boosting muted textures.

But beyond technical prowess lies liberation. Building my own "Golden Hour" preset—combining warm RGB curves with softened highlights—became addictive. Sharing it with colleagues via exported files sparked collaborative creativity, turning edits into conversations. The interface intuitively guides you from beginner tweaks to pro-tier manipulation, ensuring no tool feels intimidating. For creators craving agency over aesthetics, Photo Curves isn’t an app—it’s an emancipation from preset tyranny. My gallery now pulses with intentionality, one meticulously crafted curve at a time.

Stop filtering—start creating. Photo Curves is color grading, evolved. 🎨✨
