Thanks Jim and Steve for the info.
Now that everything is plumb and square and flat, it's time to make the perfect print. I print both B+W and color with the color head. I am going to try the C-41 B+W film that I have never tried or used. All the jars and storage bottles are taking over my darkroom. Seems I can't move without bumping into a bottle on the floor. So, I want to downsize my storage space and just keep a few chemicals for processing. I don't have much room in the darkroom ( converted spare bathroom ) and it has gotten so tight with space, I can't move for the bottles in the way.
In the 80's, I had a pro color lab and had plenty of room. Roller transport, Durst roll paper printers, 1 enlarger. Seperate color and B+W darkrooms.
Tray processing color is a totally new experience now.
I bought a bunch of Pentax Spotmatics' and am having fun going through them also. I like manual cameras and have all ways liked being the one to blame if it didn't turn out right. The new cameras have taken the fun out of shooting. Auto this and auto that.
I tried digital recently and didn't like it at all.
Enough rambling. Thanks for the info sent.
