Shooting Film at Bone Gully

We went to Bone Gully in Kuitpo Forest south of Adelaide recently, specifically to shoot on Hasselblads: the relatively old H4D40 digital camera and the much older 500CM film camera, loaded with Kodak Portra 400. Twelve shots on the roll, one roll only. Focussing this camera is quite difficult, it has no autofocus, no auto exposure, no auto anything. No electronics, no battery. When I got the film back I found that 6 shots were a little out of focus, the other six were good. I did not shoot tight enough, so the resultant scanned images have been cropped in Lightroom, no other changes made.
