Re: Ammonium Persulphate
I agree that PP is safer than acrylic, but it is difficult to install pivots on this materiel. I have been using acrylic made tanks for years on a daily basis. It holds pretty well use and abuse. The ideal etching temperature for persulfate is 140 F. I was unable to find any method to Rejuvenate per...

SYNCHRONIZATION
Thank you all for the answers to my posting about tranfering old Super 8 film to DVD
Further question: since Super 8 syncronizes at about 18 frames per second, and video at 30 frames, how you avoid recording the inter-frame black spaces in the film, when using a camcorder ?
