Hi. So far I've been using primarily ISO 100 range films. However I occasionally encounter scenes where a faster film would be preferable (e.g. need for a smaller aperture). I would like to pick one film/developer combination and stick with it for a while to get to know it well. I work in medium format and do exclusively landscape work. I would prefer to start with a traditional emulsion (? tri-x 320/400 or HP5). I was thinking about starting with the "classic" combination of tri-x and D-76. Is this a good choice in terms of optimal ballance of fine grain, perceived sharpness and accutance for landscape work in MF? If so, which tri-x should I choose (i.e. 320 vs 400) and whch D76 dilution? Also, could you suggest a staring point for speed rating, development time and agitation sequence for this combination for a condenser enlarger? Are there better options in terms of film and/or developer? I realize that any such recommendations depend primarily on personal preference. Still, I would much appreciate the advice of more experienced members so I can make an informed initial choice. Regards, Peter.
