I got on my hands a large quantity of RA4 Ektacolor Developer Replenisher, RA4 Ektacolor Bleacher fixer replenisher And C41 developer replenisher LORR. Ill guess its all 5-8 years. The C-part of the Flexicolor was gone dark and developing made dense and muddy negs. Have posted the curves in another thread. Toda it was time to test de RA4 chemicals in Jobodrum at 3 First i mixed after Kodaks instructions for small quantitys. The Supra Endura F came out with a faint image with a yellow fog all over. Next try i doubled the developer strength. Same results. The Bleachfix was next to experiment on. I doubled the strength. Same results. The fix-part of the BF had started to build a yellow layer of powder (hypo?) on the inside of the bottle. So took the bleach part in full strenght and C41 fixer as stand alone bath. As PE have reccomended, two minutes for both with waterbath between. Out came the Supra Endura with BLACK AND WHITE pictures! Didnt see that one coming. So then i mixed developer from fresh chemicals. Diluted the bleach from the old 2x10 liter kit 1:4 with water and added 100ml starter and used the same fix. 45 sec dev, 50 sec bleach water bath and 50 sec fix. Results= perfect. with a minor color inbalance compared tol Rollei Digibase chemistry. PE, what happend here. BW-pictures on all colorchemistry and paper`!
