As I mentioned in the thread on Neopan 400, I have also been testing Neopan 1600 with Aculux. Using Paterson standard times (14 minutes for a diffuser enlarger) the results were extremely dense with blown highlights and little mid tone. I have gradually played around with times and am now using the following:
7 minutes at 1+9 dilution at 20 degrees C with Neopan 1600 rated at an EI of 800. Agitation is standard Paterson recommendations of 10 seconds per minutes. The light I have been shooting in is both outdoor late afternoon light with some cloud and indoor available light. The results are lovely with many negatives possible to enlarge to 10x8 with virtually no grain. What is interesting is that the tonality of Neopan 1600 is very different from Neopan 400 and Acros 100. It does not have the silver metallic look but rather looks a bit more traditional. Mid tones are very nice. It is a bit less contrasty than Neopan 400 to my eye. It also scans (negative scans) very well. I used this at a party in a garden at the weekend and it worked very well. I am guessing that development might have to be reduced even more (or dilution increased) if I was shooting in full, contrasty light at mid-day.
Overall I am really pleased with the combination and will continue to use and refine it.
