1. What causes tiny, clear pinholes in transparency film? I figure if it was a d ust speck, it would be black. (I've had plenty of those over time!) Is it a defe ct in the film from the manufacturer? Something in the processing?
2. I bought a few used film holders, a couple of which have incredibly shiny dar kslides. The new ones I've bought have a dull finish, suggesting the shiny ones were discontinued for a reason. Is there an inherent problem with these that I s hould be aware/wary of?
