film base problem with Ilford Hp5 4x5
I have intermittently experienced a change in the surface of the base on Ilford HP5 4x5 film. Instead of it being very glossy, there appears to be an almost matte surface. Its very disconcerting. I will sometimes get a nice glossy base side, but more often get more of a matte look. I used to use TX and I never experienced this in 35 years. Both films processed exactly the same way, exactly at 67 degrees. Same Sprint Stop and Sprint Fix. The one difference is that instead of d76 i am now using hc110 with the ilford film. This matte issue doesnt always happen. Any ideas?
