Guest Posted September 3, 2017 Share #1 Posted September 3, 2017 Advertisement (gone after registration) I hope this is in the right section and sorry if it has been asked before. My 1929 camera has an Elmar lens and I generally use Ilford HP 5 film (although I also use Pan F, occasionally) I tend to develop for about 6.30 to 6.45 minutes but have read somewhere that I will get a better negative if I develop for longer, perhaps 7 and a half minutes? Photographs can be a bit light and sometimes contrasty but this may be just down to the lens which I am trying to get cleaned, I suppose.

pico Posted September 3, 2017 Share #2 Posted September 3, 2017 I tend to develop for about 6.30 to 6.45 minutes but have read somewhere that I will get a better negative if I develop for longer, perhaps 7 and a half minutes? Developed for what outcome? Digital scanning or darkroom printing, please? . Quote Link to post Share on other sites More sharing options...
Michael Hiles Posted September 3, 2017 Share #3 Posted September 3, 2017 Your lens is almost certainly uncoated - which would probably produce a bit lower contrast than a modern coated lens. I can't recommend specific times but I would expect to develop a little longer than if the film was exposed with a coated lens. Maybe 10% more, but that is a simple guess. Test, test, test.
