There's been quite a bit of talk about digitally produced contact negatives lately. so I thought I would share a strategy that seems to work well. Start with a grey scale positive. There are two ways to increase contrast and promote adequate density in the negative. One is to raise the middle portion of the grey scales curve (image/adjustments/curves). This is a very powerful method with which it is easy to over shoot. Tweak the curve maybe a little less than you want as an endpoint. then fine tune with image/adjustments/brightness-contrast. Then invert the image to a negative (image/adjustments/invert) and repeat the same steps. Then print on Pictorico brand overhead transparency material. Of course, you also need to develop an eye for those images which will translate well to alternative processes. In my hands, at least, not all do.
