I work with each photographer differently. We will figure out the level of assistance (if any) I should have in shaping how your photographs are printed.
Certain "printing adjustments" have to be made, or prints often look dull and dark.
There's many reasons why this happens, and I've spent years studying them. I can handle all the printing adjustments for you, or if you want to handle them, I can print your file as-is. (I can also provide you with custom ICC profiles for my printer.)
Almost every printing company just prints a photo as it is. If you haven't been handling the complex printing adjustments yourself, you're going to be amazed at how much better my photo prints are.
