I had some prints made at the local 30-minutes shack and got horrible results: Shadow detail lost, highlights blown, and subtle colors washed away. So now I'm going to try a professional photo printing lab for the first time. What, if anything, do I need to tell them about my digital photos to get good color fidelity? For example, color space, bit depth, monitor used for editing, etc.? Any other tips about getting good results from a lab would also be appreciated.
