Well... some problems. The Pentax Z 70 had a switch on the back with a switch that said "P" and a green rectangle as an alternative. The manual didn't mention what it was anywhere. Turns out the " P" is for panoramic and places the image to the right of the negative and crops the top borders. The idea is you swing the camera to the right and take another photo and the left and right negative match up....sorta. Surprised at some results I had that I suspect were caused by this feature. Then when I was developing, I mixed the D76 powder to the correct water to powder to temperature alright. I mixed the Fixer correctly. Both came as powders. Then I picked up the stop bath and didn't see anything on it saying it should be diluted. That was a mistake. That stuff should be 64 parts water mixed to one part yellow liquid solution. When I was younger I'd probably have been wiser. IN any case the worse it did was turn the developed negative strip into a curled up tube.

The 35 mm negatives came out alright... except for that decided roll to them.... and subsequent less than satisfactory scan.
The 120 was a total laugh. I developed them with the correct solution mix in every step. One problem was that the camera shutter was stiff and less than in time. The second problem was that there were a lot of light leaks evident on the developed negatives.
I've got plenty of chemicals left. I'm going to try the 35mm over again with some different cameras that I have more faith in. And.... dilute my stop bath dramatically this time.
