I've searched for a really long time and I haven't gotten one site or comapny that will offer slide/negative larger transparency duplications, rentals or older outdated, damaged or decent originals.
I am particulary looking for cheaper/older kinds with royalty-free licenses.
I have tons of catalogs from 1999-2002 where this STILL used to be an option. Most notably, Letraset's Phototone, Tony Stone, the Stock Market and Photodisc.
I find it strange that smaller stock places don't have this option other than the 1 in 1000 travel stock photos or fine arts photography that can give you dupes for film for very expensive prices. Also digital slides are not of my interest.
I think a wide variety of ones, (non-digital) any size. Anything you'd find in $50 cd packages (backgrounds, textures, situations, objects, people, themes, symbols, etc..)
I'm using this for the following reasons:
Here's why i really need them:
Graphic design : Zines, Magazines, Packaging, Publication using traditional non-digital (Paste-up methods) Where any kind of a file is not used.
Darkroom: Transfering color slide images onto large format ortho and lithofilm alongside experimentation. Montage/Collage, Silkscreen, and other things where film expsoure adds an extra quality and is the only way.
Art :Drawings/Sketching/Painting reference (through a projector) away from the internet, google image search and photos out of my reach.
