Depends on the camera I suppose. With the DSLR I pretty much do the same as Adrian in
reply 7 as far a settings are concerned. With the Film SLR settings are pretty much a given as far as ISO etc, if there's already film in the camera, otherwise it's "What Film do I have with me, and which one will suit todays conditions best". With the pinhole camera, it's just a case of "shall I shoot colour or B&W, if B&W, what contrast filter will I use - red orange or yellow.
As far as composing the shots, I spend time looking around, working out angles etc. before even raising the camera to my eye. Mostly I shoot landscape-ey stuff, so I'll be working from a tripod, and I don't really want to be faffing around adjusting the 'pod too much, so I'll try and get the working height and location sorted first. Then adjust the tripod to suit, whack the camera on, and start setting up the camera. By and large, I'll be working at the lowest ISO I can get away with,shooting RAW, aperture f8-f11, then meter for sky and ground to see if I need to use ND filters. Filters attached if needed, I'll re-compose, meter for the overall shot, and set camera to auto bracket +- 1 stop. Attach the cable release, press the button and chimp at the results. Adjust Accordingly, and hope that the shots look better on the big screen at home than they do on the back of the camera. The film camera is much the same, apart from maybe pushing the aperture up to maybe another stop tighter, bracketing being maybe in 1/3 and 2/3 stops for E6 film and of course the lack of chimping.
The Pinhole camera is refreshingly simple in comparison. Put the camera on the tripod, point it in the direction of the view. Check the light with an ancient hand-held lightmeter. Add 2 stops for the red filter if needed, 1.5 for the orange, or 1 stop for the yellow, then refer to my time conversion table as the lightmeter doesn't have a aperture setting for f135
Then simply remove the lens cap, press the shutter cable release button and count off the exposure time in elephants... Sometimes on B&W film i'll miss out the metering stage altogether and just look around and think "todays about 10 elephants on 125iso film" Sometimes it even
works out okay
