I'm a digital imaging newbie. I was looking for an editor for RAW files and I started using Rawstudio. It seems really good to me. I wonder if it's possible to apply camera settings to RAW files, so that they'll appear like the small jpg preview.

Nice to see a well thought out, non-political and most importantly, constructive article about the state of various aspects of dealing with photography in Linux. I thought this might be an interesting read for people on this list.

My camera (Pentax K10D) has two RGB profiles for jpeg pictures, namely sRGB and AdobeRGB, but I am not sure, if the selection between them as any impact on resulted raw files. I suppose raw data is not valued according to either AdobeRGB or sRGB, but according to each camera's natural RGB profile which can be measured. I got a profile for my camera (model) from one of the sources mentioned at http://ufraw.sourceforge.net/Colors.html / Camera profiles. I noticed, that color noise is more visible, if I use color management. I guess that is due to more saturation and/or more brightness in shadows the profile made for my camera generates. > 2.

I have tried this setting, but I haven't noticed any impact in colors displayed :( I guess the change would be visible latest when you uncheck and check the "Enable color management (experimental)" checkbox. I made monitor profile by Huey in Windows and just copied the profile under /usr/share/color/icc. Since I use a CRT monitor, I suppose a good theoretical approximation profile for it is the NativePC profile available at http://www.aim-dtp.net/aim/download/aim_profiles.zip. I am using Xubuntu 8.04. Does your system (OpenSUSE 11) have some system-wide display profile setting? > 3.

The > file appears to have the icc information for the printer embedded. Which program tells "Unexpected marker type 0x72"? Maybe you could use some other output profile (maybe NativePC or AdobeRGB?) and try to convert to the printing profile later in Gimp? (The conversion might not be very accurate, since AFAIK Gimp handles only 8bit/channel color management so far.) Or you could skip color management in Rawstudio, assign a profile that matches your system in gimp and convert to the printer profile? > Are the above steps the expected usage? If, not, what should I have set? Good question. -- Jarno Suni - http://iki.fi/8/ Ole hyv? ja k?yt? XHTML-yhteensopivaa WWW-selainta. Please use a XHTML compliant web browser.
