| As mentioned before, spherical panoramas present the
greatest dynamic range of any photographic subject and so even a film with a
lot of exposure latitude needs to be carefully exposed in order to maintain
the desired image detail. Rather than follow a set rule for determining the
exposure, I have a set of criteria that the chosen exposure must meet
depending on the direction the camera is facing.
|In full sun use the "sunny f16" rule and don't meter
||- Must meter at or above -2 stops
|Sky only, no sun
||- Must meter at or below +2 stops
|50:50 sky and ground, no sun
||- Preferably between +1 to -1 stops
|Never include the sun in the frame when metering
Photography is a wonderfully personal art form... what is right for
one person, may not be right for another so in some areas there are no
straight answers. There are times where you just have to get off your arse
and work it out for yourself ;-)
A circular fisheye lens does not cover the same area of the frame as a
normal lens so the metering may be out. Determine the film speed for your
lens by testing.
The correct exposure is that which gives you the best tonal range when
scanned. This may also vary from the recommended film speed. Determine the
film speed for scanning by testing.
