I often use films. What I use or have used :
120 format, with my P67 and P6x7 :
- TX400 : was my basic film
- Shanghai GP3 100 : now my basic film, unbeatable quality/price ratio. Cost ~1,6€/$2 per roll (x10 rolls), it is woth trying it.
- Efke R 50 : fantastic for portraits and grainless pictures. Now I will test the R 25.
- Velvia 50 : great colors for landscapes (used once)
135 format :
- APX 100 and 400 : my basic films when I do not need something particuliar (they were my first BW films I bought). The 400 exposed at 100 is good when you don't have the 100.
- Efke KB 25 : great for portraits, using f/1.5 lenses in bright sun on mechanical bodies limited to 1/1000s
- Efke IR 820 : infrared film, I use it with a Hoya R72 filter, and expose it at 1 iso (my typical exposure time on bright sun is 1/15s f/4)
- Lucky SHD 100 new : poor film, same price than the Shanghai in 120 format but far less quality. Gives pictures like if we did use an uncoated lens.
Note that I always use rodinal 1+100 stand dev for BW films, and never use a tripod (even with the 25 iso films and hardly not with the infrared ones). If you'd see some examples, just ask
