Basic question on development troubleshooting

[Steven Ruttenberg]

I processed a set of slides and two showed some pinhole. Not thru the film material, but in the image like all the color, etc is gone. They were processed at same time as other slide film with no issues. Temps were right, agitation was correct, etc. What might cause this? Used Unicolor Rapid Developer.

Also got this weird light leak or flare on one slide see pic. It was processed with two other slides at same time, in same chicory so I am pretty sure it was something I did either before during or after shot, but can't figure it out.

I used a polarizer on this shot.

Hello Steven,
Since you have the same problem previously, I think it came again more intense if you used the same camera bellows.
Keep in mind, not every time, a bellows with pin holes will show the defects on film.
Lots of reasons like bellows extension and direction of sun, will determine when the defect will be rendered on film.

Guess I better check out he bellows and see what I find.
