  1. Do you actually re-expose twice? After 1st. development and after bleach clearing? tcdp
  2. Has anyone tried to bleach RA-4 paper sheets using C41 bleach RA instead of the intended RA-4 Blix? I understand It would have to be fixed after bleach. Thanks
  3. Thank you for sharing your experince, Mr Marcus!! I might as well use the #15 Safelight to developing sheets by inspection doing reversal process with RA-4 paper. It might be usefeull in the B&W first development that should take no more than a 1.5 minutes, maybe less if I switch it on some 15 seconds after starting to develop. Thanks, Sir romeo
  4. Thank you. Can anyone tell me the difference between thses two??? Or is it that the first one is intended only to be used as filter and dnot as a safelight? Some people in the web mentions using Wratten 13 as a safelight filter, or is it pure kodak 13 safelight they are using?. Thanks everybody!!
  5. Is there a big difference between both of these filters? they are both supposed to be used with RA-4 paper in darkroom but the first states to be Amber and Wratten to be Green!! Thanks evreybody!!

    B&W reversal

    This is my first attepmt of B&W reversal using a rehal bleach and an ammonia batha afterwards. Black dots appear as courtesy of my old fix batch
  7. Excellent! Some said it's 3 ISO; So I will stick to 6 Iso, since in a sunny day it's about 1 sec at f/11 to which my camera is set up!!
  8. I reckon that info is useful for enlarging prints but I want this Ilfospeed photo paper to use it as a negative! Thank you!!
  9. Hi everybody!! What Iso speed should I rate this photo paper? I will place it inside a 6x9 camera using a shutter release. Thanks!!:)
  10. I don't want to put your statement in doubt but, are you sure of this equation? Has this proved to be exact? As someone has referred (which BTW is completly right) anydrhous carbonate stops being anyhidrous for too long when box/package has been opened and exposed to ir since moisture reconverts it to bi-carbonate in some time, this makes difficult to be accurate when measuring chemicals which might eventually lead you to a undesired outcome. romeo
  11. Yeah! It's sold in pool stores as 'Dry Acid' . I assume bleach is once used and then discarded, right? Very nice formula! I'm gonna try it soon! Thanks for sharing!! romeo
  12. Well, I live in a very humid port city, so in the end this takes me back to the beginning. I think i will just switch to Borax instead of the carbonate, or eventually buying any carbonate and adjusting the involved quantity. Thanks for the answer. romeo
  13. Very nice! Is there an alternative for Sodium Bisulfate for the bleach? Would any of these do? : Sodium bisulfite, potasium phospahte , sodium phosphate+ citrate? Any? Cheers!!
