Ryan, a friend who teaches architectural photography at the U. of A. has his students use 35mm Sensia from Fuji. Cheap, available and easily processed. He has them use Photographic Works on Grant road so they all have the same results from their film and development. This may not be the case with the color class, don't know. Although a bit pedestrian by your standards, you may find the "tonal range" of slide film to be a bit limiting until you get accustomed to it. You'll have about 4 stops between blocked shadows and fried highlights. If using E6 films, you will place highest values about 1.5 to 1.66 stops above zone 5 and let the chips fall where they may on the bottom.

No, you can't beg, borrow or steal any of my 8x10 E6. tim
