printed photos darkish: gammas unmatched?

[Gregory C]

I processed Canon 350D photos with SF HDR Studio 6.4.2 and they look great. when I printed them though, they were slightly dark; ie, darker than they appear on screen.

I'm wondering: I've set SF Options/General/Gamma-Gradation to 2.2 but I'm on an iMac and I think my LCD monitor's profile is set to 1.8. is this going to mean that images will appear brighter on my monitor (2.2 in SF vs 1.8 in monitor) than they actually are? should the gamma setting in SF be the same as the gamma setting in my monitor profile?

regards,
Gregory

Dear Gregory,

You answer the solution for your problem by yourself.
On Mac the monitor profile is set to 1.8 by default.
So the behaviour you explain is exact what I would expect.
Please set your gamma settings on your monitor and in SilverFast to same value and your prints will be ok.

Dear Thomas,

I keep coming back to this problem ;-)

shouldn't ColorSync take care of the differences in Gamma settings, automatically adjusting for SF being 2.2 and the monitor being 1.8 (or vice versa) ?


something new. I've read that most digital cameras use a color profile called the Camera RGB Profile with a gamma of 2.2. if I'm processing photos, how would this affect my settings?

if I want to get my photos printed at a photo shop (typical Kodak, etc chain store), should I be processing at 2.2? will it make any difference to the results? I ask because I haven't been happy with the colour and saturation of the photos I've printed so far.

regards,
Gregory
