What amazes me is the shutter speed of 1/8th at f8 was required with TMax 400. OK it looks like an overcast day and in the shade but with the light conditions at Pakistan latitudes I'd have expected a much higher shutter speed.

It all looks pretty good to me so the shutter speed and aperture gave the right exposure or very close to the right exposure - it's just that I'd have never expected as low a speed as 1/8th at f8.
