I started my journey with 35mm traditional emulsions shooting many until I found my sweet spot with APX 100 , Tri-X 400 and EFKE 25 as my go to films and stocked my freezer accordingly. I stumbled on the EFKE 25 as my only option to shoot landscape in 35mm and get decent enlargements More recently I have a acquired a full compliment of medium and large format cameras/lenses. I was lucky to score 50 sheets of EFKE 50 in 4x5 and just recently APX in 120 format. I always loved the combination and glow I got with APX 35mm and Rodinal and I love the look of EFKE/Rodinal combination especially with stand development. I have a couple of boxes of TMAX 100 and Acros in 4x5. I develop with Rodinal or FX-39 which is nice but I'm not as big a fan of the T-grain films. To my critical eye and due to the grain structure, they lack character of traditional emulsions. I have had good luck with FOMA/Arista Edu 100 in both Rodinal and Fx-39 (which is supposed to be more for the T-grain film) So far the availability and cost of Arista Edu 100 is great and the look is as close as I can get to the above mentioned expired film stock. Arista Edu film has a bit more grain, although very nice grain, with poor reciprocity characteristics. So, what is the closest I can get to a traditional slow speed high silver content film to replace my stock when my EFKE 50 in 4x5 and APX100 in medium format run dry? Anyone shooting Rollei RPX25 in 4x5 before I order a box? I picked up some RPX 25 and RPX 100 in medium format and will be testing those. Can anyone tell me their experience with Tri-X 320 in 4x5 and how the grain compares to Arista Edu 100 in 4x5? I love Tri-X 400 in 35mm. What's up with the Tri-x 320 version ...is it a different emulsion? Thank you!
