I am looking for recommendations on which online photo printer(s) do the best job of matching images edited in GIMP and saved with the GIMP sRGB profile. I have used Mpix for several photos, and have seen some difference between what I see onscreen and what I receive from them, which I don’t expect to eliminate entirely, but to minimize as much as possible.
My monitor is a six-year-old HP LA2405wg, which I bought because of the 16:10 display ratio. I have used aids from online to calibrate it. I haven’t invested in profiling/calibration equipment yet because I don’t think I have reached the level of competence to justify the investment. When I reach that point, I plan to get a new monitor and/or profiling/calibration equipment.
I use the Mpix provided profile to soft-proof, but I don’t have the knowledge and skill to pull the out of gamut areas back into gamut. I have also used profiles from Bay Photo Lab and Nations Photo Lab, but have not had anything developed by them yet. I see differences in the areas marked out of gamut among them.
My camera is a Canon PowerShot G9X Mark II. I process the raw images with darktable, Raw Therapee, and sometimes Canon’s Digital Photo Professional 4.
Finally, I have read many articles on color management. Most of the information, though, is related to doing things that are beyond the scope of my equipment at the moment.
