It seems that I could not get any contrast control from the enlarger that I just acquired. Just to test the enlarger's contrast control. First, I tried with a low grade filter(M0, Y0), then I used a very high contrast (M170, Y0) just to try if I could get some contrast. The two prints were almost the same. There was no contrast added to the second print. Later on, I tested the enlarger's light source by placing a white paper under the lens while dialling the magenta filter, and I could actually see the color of the light change. If the filter is actually working, I could not think of any reason the contrast control did not work. I have another condenser enlarger which is very easy to adjust the contrast, just by inserting different filters. (same chemical, same negative, same paper) Could anyone help me with the issue? Thank you!
