I have some 35mm and 2 1/4 Slides that I would like to use to make enlarged negatives for Pt/Pd printing. So I have a few questions for those that have actually used chromes in their process. - What panchromatic films are best suited to making the enlarged negative? I had considered Tech Pan but I assumed there might be a problem with due to its increased blue sensitivity. - How much of an increase over 'normal' development is required to get the contrast needed for Pt. printing? I thought this might differ from development of an in camera negative because of the character of the chrome materials tolerance for contrast. - How much do you enlarge your image? I never scrutinize my final images with a loupe but like things to look smooth from average viewing distance. Thanks in advance for the benefit of your experience.
