Re: 12 jpg

Hi Roberta,

Looks like you already figured out what a 12 value is when saved as a .jpg. Now the photo lab want your photo in Adobe RGB colour space as this is their preferred method for printing. The difference between sRGB and aRGB is the aRGB has a much larger colour gamut than sRGB.

To see the difference in Photoshop go to the edit menu select Assign Profile and you'll see a dialogue box with 3 choices:-Don't colour mange, Working RGB, Profile select Profile and in the drop down box to the right choose Adobe RGB (1998).

Once selected if you switch between Profile and Working RGB (which is probably sRGB IEC61966-2.1) you should see a significant change in the photos colour on the monitor screen.

Hope this helps.

Re: 12 jpg

sRGB is probably OK - what you don't want to do is get an Adobe RGB image printed in system that can only cope with sRGB as the colours will look wrong. It's safer the other way around.
