Can I extract an ICC profile from a TIFF (or any other format) file using Photoshop?

I hear Corel can do it, but what about Photoshop?

I don’t know if you can "extract" the profile, PhotoShop does read the embedded profile from several file formats, including TIFF. If a file’s ICC profile is different than the current workspace than options are presented, such as switching to the file’s profile.

Yes, I know that it can read them. But I want to *extract* them and save them to my HDD, like CorelDRAW.

I need to create some artwork in Illustrator and need it to be color-managed using the profile used in the TIFF files. I *could* ask for them, but that’d take time.

Does anyone know of any freeware tools that could rip the profiles off a TIFF (or any other format)?

The information is in regular text, so you could bring the TIFF file up in a text editor and search for it. maybe search for *desc*. Examples:

Simple solution: Open one of those TIFF files in Illustrator. Select all and delete. That gives you an empty document, still in the correct color space and with the correct profile. Start working from there.

I found out that *Imaging for Windows* shows the profile information under File->Color Management, see if you have that application installed. It’s a Kodak application provided to Microsoft. I don’t know how I got it on my system but maybe it comes with the operating system or some other install.

Also there’s a plug-in called "Der Curvemeister" that shows a comparative color profile as a set of curves, although I’m not as yet sure what it all means in terms of furnishing useful information. The ICC profiles are evidently a set of fairly complex curves, and the numbers associated with these must be coefficients of some kind–does anyone know how to correlate them?

Der curvemeister shows what’s known as the "neutral response" curve, meaning the RGB values assigned to a neutral gray, ranging from a brightness of zero to 100.

This is generally interesting for device profiles, such as scanners, cameras, and printers because the RGB values usually do not coincide with one another.

The neutral response curve is just a straight line for working spaces such as Adobe RGB and sRGB. For those spaces, the Gamut viewer image is interesting.

I believe you can extract the profile from a PDF.
I forget if it is with Acrobat or PitStop –
I will check it out next time I think of it.
If you have those, though –
you could save the file as a Photoshop PDF
and extract the profile from there.
