Hi. I own a Fuji GX 617 and a Mamiya C330, and I shoot Velvia with it. From a 6 x 17 slide I got a 7 foot print made, and I got some 24 inch prints made from the 6 x 6 slides. I got them printed on a lambda printer and mounted with matte finish, and they look very good. But I'm wondering if they might look better glossy. I didn't get them mounted glossy because I was afraid of strong reflections. Are there rules that say when you should prefer glossy to matte, and what is most used in exhibitions? Thank you, Dirk.
