Hi venchka and thanks for your message. I checked with Dwayne's and they do not push/pull. I may just get it processed locally and stay away from the practice until I start doing my own. I am a novice and tried it for fun on some old expired film which is why I don't really want to spend $!5-$20 on it. Dwayne's service seems to me to be the most complete. So far, it is the only one I have seen to process color, B&W, C-41 B&W and E-6 and offer scanning for each format at a reasonable price.
OT: Dwayne's told me they can process B&W C-41 as true B&W or in color as sepia. Has anyone tried this?
