What color space should my camera be set to?
Images shot with digital cameras are normally set to a default RGB color space (sRGB is the most common) however MOO prints in CMYK. Not to worry, we’ll convert them to CMYK using our own profile.
Remember: where possible, preview and edit your photographs in CMYK. Colors displayed on screen will always look much brighter and more vibrant than the final printed products, so you may need to compensate for this when editing your images.
If you have a color calibrated screen and would like to preview or upload your images in the same CMYK colorspace MOO uses, we recommend the following settings: Coated GRACOL 2006.
Does all this talk about acronyms and color spaces make your head spin? Here's a helpful video that shows the difference between RGB and CMYK.
