E6 is a definite "no,no" for B&W reversal. All the silver is bleached away, with the intention of leaving only the coloured dye image, and since B&W film ain't got no dye image, you're left with nothin'.(posted 8991 days ago)I used to make copy slides by laying the body of an SLR on the enlarger baseboard, focussing via waist-level finder, (i.e. with the prism off). After a bit of experimentation to find the exposure time, it was a fairly easy thing to do, and allowed a bit of cropping as well.
