I's be interested in hearing from anyone who might have more info regarding using orthochromatic film for x-ray type photographs. I recently came across a photo book that made reference to using ortho film for making what looked like x-ray images of flowers. I already know/have seen great examples of x-ray based floral images, but as this isn't a realistic option for me, the ortho route sounds promising. Only problem is, I haven't been able to learn any more via extensive "googling". etc,... I'll look forward to your replies.
