Re: One hour sunset picture exposures?

[Bill Glickman <bglick@xxxxxxxx>]

George,

    I guess I should have explained further... I do not shoot the shot if it
needs 30 minutes at sunset... I was just stating that if one shoots a 180
deg. sunset, even with 200 speed film, its not uncommon at f 16 to see 30
minute exposures.... hence the benefit of MF lenses over LF lenses, whereas
at least we have the option to shoot at 5.6 to reduce the 30 minutes down to
say 4 minutes, which is a bit more feasible.  The fixed fl roundshot 70's
use LF lenses which the MTF curves make it mandatory they shoot at 16 or
above.  That was my point... make more sense now?

Regards
Bill G
