Hello everyone, I'm just started my first darkroom prints and want to do everything correct from the start. So a few questions: * I'm using a 24x30 paper (actually my measurements show 24x30.5). What is this standard and where it came from? Why not A4? How does it correlate with film frame format? I would be greatful if you can point me to any ISO standards to clarify what I'm dealing with. * I'm using a simple easel which allows me to make fixed offsets from the edge. Are there any recomendations for it's size? I'm not going throuh complicated process of preparing my prints to exibition (like described in Way Beyond Monochrome) but rather interested in best precticies from impression point of view. How should I calculate the size of the borders? Is it ok to crop 35mm frame to keep 1.25 ratio? (I like evenly filled paper) How do professionals do? p.s. to moderators: I'm new to the forum, so if you move the topic to a more suitable section please notify me somehow cause I don't want to miss the replies.
