Hi i was wondering if you guys could help me, my task at work is to begin to archive a load of very important architectural drawings. Most of these drawings are pencil sketches onto paper no bigger than A1. However some of these drawings are very light and cannot be clearly seen and some maybe very detailed. My job is to make a digital archive of these drawings and develop a cataloging system for them. We are about to buy a high resolution scanner to scan to most important drawings however for now we just need reference images of each drawing for the catalogue and hence have decided to use a camera along with a tripod mounting next to some sufficient lights. I use a Nikon d100 and have finally setup the tripod and camera to line up with an A1 page. My question to you guys is what format should i begin to save these images as, jpegs, raw, tiff etc. Also as some of these drawings are very fragile some post production may be needed to darken the lines via photoshop.
