Interesting, because I always used a water stop with the Efke films. The pinholes were there regardless of this. They were minimized when I started using a water bath during processing, but they did not go away completely until I switched to TF-5 as well. But you use a stop bath and an acid fixer, and have no problems. Everybody's process is different.

I had not heard of alkaline stop baths until this thread. Based on PE's take on them, I don't think I will try one. I will stay with water with sensitive emulsions. I skip the stop entirely with PMK. I think I will give TF-4 a try and see if it gives a stronger image stain.

Just to clarify, TF-4 is alkaline, correct?
