Hello!(posted 8350 days ago)Thanks a lot for sharing the information!
I love Efke films! I use a lot of Efke R50 and R25. These films are ortopancromatic and are made this way. R50 and R25 are perfect for portraits taken with lamps as light source. You don't have to use filters. Superb skintones and super fine grain. If you're shooting landscapes you would use a tripod, so exposing three instead of two stops more when using an orange filter isn't a real problem as long as you keep in mind how this film works.
