We all know that the lighting conditions under which a print is viewed has a great effect on the appearance of that print. I only print B & W and usually judge my prints by holding them next to a window but out of direct sunlight but our house is small with small windows and when I move even a couple of feet away from the window the effect of the print changes. So how do you judge your prints when printing? What light source do you use and do you use more than one? When do you decide the print is right?
