ok, odd title I know but hear me out. So, Ive been experimenting with Tri x a lot these days in 6x7, just trying to find out what I like (developing my own obviously). I had just got a new to me Pentax 67 and took it on a sunset hike a few days ago with a roll pre-loaded and took some shots to test it for light leaks. When I brought the roll home ,and developed it I discovered it had a tone to it that I wouldnt normally get from tri x and I REALLY liked it.... so I set out all weekend to try to figure out what it was that did it. Was it my process, or just the lighting at the moment...or a combo of many things. I ran 5-6 rolls this weekend and could re create it (so far). Now, I think I know what it was but Im not sure since I dont know THAT much about how chemicals effect film... anyways, heres the details on what I did: - Tri x shot in 120, exposed normally (ie not over or under)...spot metered. - Orange filter on lens (exposure comp'ed) - developed in Rodinal at correct temp... BUT I did it at 5 min vice 7 (1:25)...I misread the massive dev app and developed it as if it was Tmax ...so two minutes under. - Normal agitation, normal chemicals for fixing etc. No post work done. The photos that came out have a very.. thick grey tone, nice darks and great mids but not a ton of highlights, so its not all that crunchy and grainy (which i dont mind ..but not in this case). The other rolls I 'tested' this weekend came out normal Tri X way.. grainy and contrasty (I changed the development concentration and but didnt do the reduced time yet. I kept it at 7 min for 1:25 and 11 or something for 1:50). So, Id love to explore this more and get it down that I can repeat. Can anyone shine a light on what I did wrong right? Is it the lack of development time that caused it to expose correct but the highlights not to burn in? Thanks everyone!
