I have heard a lot of good things about Efke films.So I got some EfkePl100 from JandC in 4X5.I shut about 10 frames during the day, coming back from my sons place around ten o`clock at night it was a beautifull turn of the century corner store on my way home lit with street lights and interior lighting.I got my Seconic L508 meter out and try to get to mesure available light .Spot meter was showing under exposure what ever setting I used and reflective was showing about 30 sec. which I felt was not enough to expose this scene.I used a guess and exposed first exposure at f22 for 3 min. and second one at the same f22 for 5min. Now to my question. What would be the proper way to meter and expose scene like this?And how should I develop the two negatives?
