To expound a little on this topic of slides:Originally Posted by Sparky
I entered a Members' show at a local arts center and they required slides of the work with the application. When I delivered my work to the gallery after having been selected for the show (all black and white prints) I had a chance to talk to the gallery director about slides, which (let's face it) are a royal pain for photographers.
She said that the main reason she required them and was reluctant to accept CDs or DVDs was the fact that slides are the truest representation of the work. This director has actually reneged on acceptance of work and thrown people out of shows at delivery because the actual work was of much lower quality than the representation of it which had been submitted on the CD with the application. So she now attaches a proviso to the announcements for shows to the effect that acceptance of any work submitted digitally is entirely conditional upon approval of the actual work, which must pass muster before they'll hang it.
I later organized a show involving the work of 5 different photographers and again submitted slides. The best ones by far were the ones submitted by Scott Killian, who as Sparky suggests scanned his prints and then sent the scans to be digitally output as slides. They were far better than my EPY photographs of my prints.
It is often logistically impossible to show prints, especially when you are answering a call for submissions for an exhibition. If done well, slides are almost as good as the original prints and are much more convenient for everyone concerned.
