Adobe Camera RAW (ACR)

How to create an ICC profile using
RAW images and Adobe Camera RAW
ACR is part of Adobe Photoshop and a popular way to process RAW images.
Unfortunately ACR doesn't support camera ICC profiles directly, so we are using them in Photoshop after the development.

Whitebalance & Exposure
|
 |
After opening your RAW file within ACR,
- change to the «Whitebalance Tool»
- click on one of the white patches of the «ColorChart» and
- adjust the exposure to a value between RGB 235 and RGB 245.
|
|
Workflow Options
|
 |
Click on the link at the status bar of ACR to open the panel of the
Workflow Options
Select ACR output color space.
You have the choice between the follwing working spaces:
- Adobe RGB
- ColorMatch RGB
- ProPhoto RGB
- sRGB
We do not recommend a certain colorspace, because the choice depends on your camera model.
From a technical point of view you should take a large colorspace like ProPhoto RGB, but we had our best results with Adobe RGB and sRGB.

Saving the Image
|
 |
Click on the button «Save Image ...» on the bottom left of ACR.
- Choose your destination folder,
- select "JPEG" as file format and
- a quality between 10 and 12
Click on the «Save» button
Now you are prepared to create an ICC profile out of the Reference Shot using our Online Profiler.
