My wife is an installation artist (as well as a printmaker, painter, etc etc and photographer) She is having an exhibition in the local public gallery this coming winter and the curator wants along with and in part instead of her installation large prints of the shadows from her installation. She wants 60 by 90 inch prints. I think she needs 8 or 10 prints. We (as in me the helper and she the presser of the shutter) are planning on using a 69 back on the 4X5 She Hao view camera and a 90 Caltar lens to shot the images and scan them with Nikon CS 8000 using Scanscience fluid scan.
See if the image gets attached. Trying to show what she will be photographing and enlarging to the 60 by 90 size. the printing will either be done by herself at a self directed workshop or else sent to Toronto for Elevator to print. The workshop works out slightly less expensive and she will be in intensive learning for two weeks on digital printing and we both could use the knowledge and saves money on shipping the final product.
My question is given that it is of shadows which of these two films would be our best options Velvia 50 transparacey film or Portra 106 NC negative film?
