And you have a monitor that can display the full aRGB gamut so you can accurately edit your images in that colorspace? And you're sure your lab doesn't convert to sRGB when you send them an aRGB image?

Izzy, who do you print with?

Izzy -I think It's worth point out that the Pantone inkset is a little larger than the sRGB colorspace. Modern inksets with increased gamut are often still smaller or smaller and offset from prophotoRGB. Being within the colorspace of the output can be very useful for conversion to a CMYK colorspace and still produce very good results. One has to down convert the image to go to the printer anyway - data is lost, I'd rather hand the lab an sRGB and do the conversion to sRGB myself rather than rely on a lab to do that conversion.

"Uncalibrated" is what EXIF calls the Adobe RGB (1998) color space.

Technically, "Uncalibrated" could be any color space. But the current EXIF specification only provides one uncalibrated color space. It has exactly the same gamma and exactly the same red, green, blue, and white points as Adobe RGB (1998), but they don't call it "Adobe" because that's a trademark.

Good info Doug, thanks
