with roll film I have never developed for contrast, that can be taken care of in the print, to me its easier to meter a scene, placing shadows in zone III making sure you get good detail, being careful that your highlights arnt blown out, if your highlights dont fall above zone VIII you will be fine. your neg will have plenty of contrast, if your highlights fall below zone VIII with your shadows on zone III, you can use contrast filters to boost it up, thats what i do, seems to work well. good luck
