Silver gelatin is the museum approved term for b/w photos as it describes the material substance of the print. If you look at any survey of 19th century silver gelatin photographs you'll see red , cream, blue, brown, green, yellow, red... I have brownish, purplish and greenish contemporary prints. Not a lot of black and white around if you define black as 'absence of light' and white as 'presence of entire visible spectrum'.(posted 8268 days ago)Liquid Light on watercolour paper is in museum terms described as 'photographic emulsion on rag paper'. [Museums don't usually use proprietry names to describe prints although I have noticed with new digital media the odd one is creeping in.] If you live in the US Liquid Light is not expensive to use [and I wouldn't describe 11 x 14 as large format, I've seen whole rooms coated in the stuff] but you should size your paper to stop it sucking up too much emulsion if cost is a concern.
