Just a little high speed cinematography mayhem with my brother and his giant air cannon, plus a junk shuffle alley he wanted to get rid of! Here's the d*g*t*l video - I'm still working through capturing the high speed 16mm stuff then I'll edit it up and put it all on YouTube:
The scratches are similar to scratches I got on roll I had processed by a local lab this summer. The scratch wasn't real straight and wandered across multiple frames so I don't think it was a problem with the camera. To make matters worse, I could see what looked like water marks in the sky in a number of my images. Then to top it off, I asked the lab to make a CD scan of the slides and that turned out to be one of the worst scan jobs I've seen.
I mentioned the problems to the lab, but not sure if it did any good.
So on my last roll I decided to mail it off to Dwayne's and I was pleased with what I got back, but I would prefer to patronize my local lab.
Froboz: have you tried CSW in Chicago? (Lake and Damen)
Ever since Helix shut down their Highland Park store (where I could drop off slides on my way to or from work nearby, and they would shuttle them down to Chicago and back) [and then they went totally out of business anyway], I have used CSW for my processing... many, many rolls of E6. They do a fine job, though to be honest their most recent work has been fairly dirty/dusty/watermark-y. The big problem is their staked slide mounts, which jam my autofeeder. So I've been trying other labs...
The owner of the lab got back to me and very much wants to get to the bottom of it - I'll be sending him some of the slides back for inspection (and he's already given me a credit for future work greater than the amount I paid for this processing!) Impressive response.
Aha! Upon investigation of some slides I sent back, the lab discovered that they were actually some sort of drying marks on the film, not scratches. They wiped off when rubbed with a cotton glove. They suspect it may have occurred on the occasion of dumping and renewing their chemistry, since they don't just keep replenishing forever.
I'm going to take them up on their offer of free replacement processing of my next rolls, and fully expect to be happier with the results!
