I am getting ready to shoot a rather large project with my 4x5 camera. We are looking for 35-40 finished high quality images. The subjects is architecture both interiors and exteriors. The catch is that I will have three days to shoot. After that I cannot get into the spaces again. It is a hospital and once many of the rooms are actually put in service the rooms will be in use and I simply am not going to be allowed back in. I have secured a stock of e100g my preferred film for this type of thing along with a stock of FP100c45. I will not have the luxury of taking some shots and sending them to the lab as a test as the location is rural. I have not shot film with my 4x5 in a number of years and films have changed. The work process I follow is as follows; set up the scene; meter, shoot a BW instant test shot to make sure that things are generally looking OK or need/make adjustments. Once things are ready I shoot a color instant as a final test. In the old days (when Polaroid was still around) the color instant gave a pretty good exposure test regading highlights, shadow detail etc. The price of film and processing has gotten $$$ as you all know so I would prefer not to waste any more then necessary. I am curious if someone has used this workflow and how the various films now compare in terms of exposure, similar contrast, detail etc. I typically find myself shooting 1/2 stop under on the interiors and use some supplemental light to put detail in the shadows. The e100g will be lab processed then scanned as this will be converted into a presentation book. I am sure there will be lots of good advice. Many thanks in advance!!!
