Hallo, alle SW-Umkehrentwickler !
Versuchen sie den folgenden (leider nur in Englisch):

B/W Slides

Use only silver halide films having a clear base and an anti-halation layer (AHU) that will clear out during the process - or no such layer at all !
Concentrates (for 1 litre):
bleach -> 25 g potassium dichromate (kalium-di-kromat) +
100 g sodium bisulphate (natrium-hydrogenium-sulfat)/monohydr.
-> if you don't like mixing this stuff you may use the bleach from E-6 or any B/W rev. kit
clear -> 250 g sodium sulfite (natrium-sulfit)/anhydr. (desicc.)
-> may be substituted by HCA (neutralize the bleach)
Mix 1+4 to make a working solution
Development (20 C):
1st dev. (see table) ANY high-energy "positive" (paper) developer (Dektol etc.) 1+4
-> for more projection brilliance you may want to add some silver solvent =
ca. 9 g sodium thiosulphate (natrium-tio-sulfat)/pentahydr. -----
this amount is critical: a larger dose quickly rubs out too much silver and a smaller
pile yields too dark an image !
wash (in running water)
bleach
wash
clear
wash (open the tank at this stage; a sufficient re-exposure is essential for
orthochromatic films, i.e. use a transparent reel/spiral !)
re-exp. (100 W bulb = white light) 1 min./side (reel top & bottom)
2nd dev. (Dektol 1+4, no solvent)
wash 1 min.
fix (Hypam or similar rapid stuff)
wash 5 mins.
hypo (Kodak HCA or similar)
wash 5 mins.
wet (Agepon 1:200 or similar) 1 min.
All other phases/stages 3 mins. each.
Films (daylight):
135-format ISO 1st dev. (mins.) EI contr. response chrom. (sensit.)
Kodalith Ortho (Type 3) N/A 3 8 H graphic ortho * = High-Contrast
Slide = HCS (bulk film)
Maco ORT 25 18 DX N half-tone ortho
Kodak FRP N/A 8 ? 12 ? N half-tone ortho = Fine-Grain
Release Positive (bulk film)
Agfa Scala 200 10 DX N full-tone pan
Kodak TP N/A 8 16 H half-tone pan * = Technical Pan
Maco UPC 64 10 25 N full-tone pan

FomaPan 100 ? 100 ?
* means no silver solvent needed !

Habe beinahe alle erw?nte filme versucht und die Ergebnisse sind sehr gut.
FomaPan muessen sie leider erst probieren (Erstentwicklungszeit)...
