help me troubleshoot my first attempts and B&W reversal
got the itch to try and do some reversal processing. went to keeble and shuchat to buy the chems and was happy they had all of them but the acid. I did a lot of research and thought i would use iron off for the sec develop, re-exposure and fix steps as it simplifies things. but I'm thinking that could be where my problem lies. in my research many people suggested using traditional grain films and slow speed films. so i loaded up a short roll of PanF+ and shot two things with 8 exposures each starting at EI 16 and going to EI 100. followed my directions of choice and they negs all came out really really dark. you could see an image but only on a light box and still it was very dark. so i went out with another roll of PanF and a roll of Ultrafine Extreme 100 aka kentmere 100 to try another film. i stuck to the same directions to make sure i didnt mess something up the first time. with the Panf the results were the same. very dark and i assume would not project well at all. the extreme 100 on the other hand came out pretty well. since its my first time i have no idea what a proper neg would look like, but when i compare it to my control picture, one shot with provia, it seems a little darker (but could just be my perception as its black and white and not color).
I've scanned in 4 shots to post so you can get an idea. with the Panf EI of 16, i did one with no adjustments so you can see whats there. I also re-scanned the raw scan and used a white balance color balance and it does a good job showing whats on the slide. so i would guess I could save images with some work in the scanning and PP department. But i would prefer to get it right when developing. with the extreme just the one with no color adjustments, shot at EI 40. the other is the provia shot
my process done in a patterson hand tank
1) first developer 12 minutes with continuous agitation in Dektol 1+1 and 7ml hypo mixture which is made up from 7 grams of sodium thiosulfate in 250 ml of distilled water. then a 2 min wash replacing water every 30 seconds
2) bleach 9 minutes continuous agitation in a 2 part mixed 50/50 part A is 6 grams of potassium dichromate per liter and part B is 30 grams per liter of sodium bisulfate. I could't find locally any place to get sulfuric acid. then a 2 min wash replacing water every 30 seconds
3) clear for 3 min continuous agitation in 30 grams per liter of sodium sulfite. then a 2 min wash replacing water every 30 seconds
4) 2nd developer, flash and fix 4 min agitate first 30 seconds then 2 inversions every min in 2 tsps per liter of iron off which is mostly sodium metabisulfate and sodium hydrosulfate. then a 2 min wash replacing water every 30 seconds
5) 1 min in photo flo solution
so any recommendations or help would be greatly appreciated. you gotta start somewhere. I knew i wouldn't get it right the first few times but would like to get it better sooner rather than later. thanks.
