Picture Window Pro and RAW files

Matt,

I thought I'd try shooting in AdobeRGB this weekend.
When I came to use C1LE, I got a bit confused about the colour management. I can pick the Camera Model and a Camera Profile, and also a Destination (working) colour space. When you process the image, options include converting to the Destination (working) space. But how does C1LE know which colour space the image was recorded in? It's certainly not embedded in the .PEF file (bit of an omission that). That suggests that the camera profile is really a 'tweaked' colour space (most appications seem to use colour space and profiles interchangeably), say sRGB, and that if you record in AdobeRGB, you must pick that as the Camera Profile.

Have I got this right?

PygmyT,

The source profile is selected under the menu "Workflow" / "Show Color Management Settings". You should see the "Camera Product" as "Pentax istD" (or whatever).
That's where the "camera profile" is. And no, it's not sRGB - it's much wider than that

And it's those source, camera profiles that are the paid-for addons. The Pro version of Capture One allows you to generate your own source profiles and allow very fine, selective colour manipulations. As I've said in other thread you can try other camera profiles (even the wrong ones) - and they'll give completely different responses.


In the second section of that window you'll see the "Output Destination (working space)" - which for your purposes will be "Adobe RGB".

Note that the camera profile is typically a very large colour space, and there'll be a transformation "down" into the output space - whether that's AdobeRGB or (worse) sRGB.

Be aware that your editing application will need to be colour managed as well, and preferably your monitor calibrated and profiled

I think the penny just dropped - the raw files are not affected by the camera setting for sRGB or AdobeRGB - this affects on-camera conversion to jpeg. So raw converters take the raw file, with its CCD-specific colour space with the wide gamut, allow you to do all the tweaking before losing any information, then convert to the destination space, preferably AdobeRGB if editing in PS or printing with Qimage, or sRGB if for display on the web.

Thanks for your help,
PygmyT

Bingo!

(And "ProPhoto" colour space for seriously wide colour manipulation in 16-bit TIFF)

We're moving off-topic here so maybe time for a new thread? I've used mandrake Linux a bit (transmogrified into Mandriva Linux). It was the simplest OS installation I carried out, but then I wasn't trying to attach cameras scanners and printers to it. Just a basic box for email and web browsing.

My next new PC will run some form of *nix as I am sick to the back teeth of windoze and its built-in "official" spyware http://news.com.com/Microsoft+Heres+how+to+halt+WGA+alerts/2100-7350_3-6088669.html

(and to think I'm a fully paid-up MCSE!)

I would recommend thoroughly Slackware V10 this was the best Linux I found to easily install on my HP laptop, and much to my surprise having read how difficult it was..... it was easy and rock solid.
