I just had to load the film into the film canister in total darkness. The rest could be done in daylight. The prints I did from Ectachrome had stunning colors (even blacks)except when printing from color slides everything you know about printing black and white and color film is backwards.
Yes...we had a closet for doing the film canister thingy. I had to be so careful to spool the film onto the stainless steel reel, that spiraled out from the center, close the canister, add the chemicals, seal it up, and then do the rumba for a precise amount of time to agitate the solution evenly throughout the can!
