development times for HP5+ at iso 1600?

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

hi. kinda new here, please forgive my ignorance...i shot a roll of HP5+ at iso 1600 in an attempt to get some grain...not "big" grain, but lots of grain i guess..just experimenting. i developed in t-max developer for 9 1/2 minutes. the prints came out very contrasty, with little highlight detail ( the skies in all the backgrounds were all white). did i not develop long enough, or too long? any times that you may suggest would be greatly appreciated. thanks.

Welcome to the world of push processing. What you saw is exactly what happens when you push. Contrast increases and highlights block up. The reason is that extending the development causes increases in the density in highlight areas more so than in shadow areas.

If you are trying to get more grain but without sacrificing contrast, try shooting delta 3200. I haven't shot much of it but people around here seem to have good results rating it at about 1600. I'm not sure about processing times. Look around the forum and you will come across someones recommended developer and processing times.

You can try Neutol 1+3 also, gives dreamy images with Tri-X at 1600.

I tried it at 3200asa!!!! don't the results were VERY thin negatives the guidelines at high push rates should be extended if in doubt try double?
