How are photographers using Color.io?

Color.io is a complete, LOG-based RAW processor that develops RAW images in a unique and filmic way. Many Color.io users are photographers who develop and color grade images with the app or create 3D LUTs for integrating the advanced color processing capabilities into third party workflows.

Raw photo development in Color.io is powered by VisionLog - an ultra-wide-gamut, log-encoded color space. VisionLog encoded raw images are an ideal starting point for creative color grading and look development. The VisionLog curve has a wider dynamic range than a standard linear encoding, which means that it can capture all detail in both the highlights and shadows of an image. Compared to traditional raw development workflows you can think of the logarithmic encoding step as an automated shadow and highlight recovery that creates a low-contrast base image with all image details non-destructively compressed into a very wide tonal range.

After loading a RAW photo into Color.io, all you have to do is select "VisionLog" from the camera dropdown before you dive into presets and get creative with the tools.

What image formats are supported by Color.io?

Color.io can read almost all image formats including raw files from over 600 cameras. Here's a non-exhaustive list of the image file formats you can open and edit with Color.io:
.jpg, .png, .gif, .bmp, .tiff, .dpx, .dng, .cr2, .cr3, .arw, .nef, .raf, .dc2, .rdc, .bay, .crw, .cap, .dcs, .dcr, .drf, .eip, .erf,.fff, .iiq, .k25, .kdc, .mdc, .mef, .mos, .mrw,.nrw, .obm, .orf, .pef, .ptx, .pxn, .raw, .rwl,.rw2, .rwz, .sr2, .srf, .srw, .x3f, .3fr

How are filmmakers and cinematographers using Color.io?

Color.io a dedicated tool for developing show looks and film emulation LUTs for on-set and post production workflows. It uses a proprietary processing engine that models the color response behaviour of analog film. This engine is natively color managed and supports the creation of highly color stable and predictable LUTs for hundreds of cameras and outputs, from cinema projection to online delivery.

With a cloud-based look library and tools for deep gamut shaping, 3D LUT visualization and an AI-backed color stabilisation engine, Color.io is the instrument of choice for many pro cinematographers and colorists when it comes to streamlining look creation and look management from set to post and across projects.

What LUT formats and sizes can Color.io create?

Color.io can generate 3D LUTs for most color grading and video editing applications like Davinci Resolve, Adobe Premiere, Final Cut Pro and many others. You can also generate color grading LUTs for Unity and Unreal Engine as well as Cinema4D RedShift and other 3D tools. It is also possible to export LUTs to Adobe Photoshop, Affinity Photo and other image editing applications.

You can find all supported 3D LUT formats directly in the export panel of the app.

Does Color.io support HDR workflows?

Yes! Color.io is ACES color managed so every look you create with the app is automatically compatible with a large number of input and output devices, including HDR. Outputs in ACES are called ODTs and for HDR you'll want to select REC2020 ST2084 from the dropdown with the little display icon. And that's all there's to it.

What cameras are supported?

Virtually all cameras. Color.io has even extended ACES with proprietary IDTs to support cameras and workflows that are not directly supported by the official ACES version. At the time of writing, Color.io supports the following cameras and input color spaces:

- sRGB
- Rec709
- ProPhotoRGB
- Adobe RGB
- Apple ProRes Log
- Apple ProRes HDR
- VisionLog
- Arri Log-C v3
- Arri Log-C v4
- Arri REVEAL Rec709
- Arri REVEAL Rec2020
- BMDFilm Wide Gamut Gen. 5
- DaVinci Wide Gamut / Intermediate
- BolexLog WideGamutRGB
- CanonLog 1/2/3 BT2020 (Daylight & Tungsten)
- CanonLog 1/2/3 CinemaGamut (Daylight & Tungsten)
- DJI D-LOG D-Gamut

- Fuji F-Log 2 F-Gamut
- Leica L-Log
- GoPro Protune Flat
- Kinefinity Kinelog 3
- Nikon N-Log BT2020
- Sony S-Log / S-Gamut
- Sony S-Log 2 / S-Gamut (Daylight & Tungsten)
- Sony S-Log 3 / S-Gamut3 & S-Gamut3.cine
- Sony Venice S-Log 3 / S-Gamut3 & S-Gamut3.cine
- Panasonic V-Log / V-Gamut
- RED RedLogFilm DragonColor 1 & 2
- RED RedLogFilm RedColor 1 - 4
- RED LOG3G10 WideGamutRGB
- Z-Cam Z-LOG 2
- ACES, ACEScct, ACEScg
- ADX10 and ADX16 for the film folks

This means you can create LUTs not only for all of these specific cameras, but also for every camera that outputs sRGB, Rec709, ProPhoto or Adobe RGB. Oh and we automatically debayer RAW image data from over 600 cameras not listed here into VisionLog, which you will then be able to process using Color.io. What a time to be alive!

How do I update to the latest version?

Color.io is a PWA (progressive web-app) so it self-updates automatically. Whenever you launch the app, the latest version is fetched and installed in the background. You might sometimes receive an in-app notification for major updates or announcements from Color.io.

How many devices can I use Color.io on?

A single Color.io Account can be signed in on up to 2 devices at the same time. When you're switching to a third device, just sign out of your first or second device to unlock access. You can remotely mange your device sessions in your browser with your Color.io Account.
