(Not a typo, this lens is a "Supep" )
We get crowds of costumed visitors in the street, so far over a few years I have just done flash on the Pentax ist-ds and Pentax MX which has been OK.
Some visitors carry lights and often they have bright white costumes.
This year I want to try to learn a bit about long exposure shots with moving people, using the 6x7 55mm on a tripod at some distance.
I measured the ambient light last evening, it will be 5 ~ 1EV which is down to 8 to 12 secs at iso 100 f/5.6.
I have Ektar 100, Fuji 160 and Fuji 400.
The lens is on a Speed with focal plane shutter , so I get 8 shots, and I will have to use T mode with a stopwatch.
I think the general focus distance will be about 8 to 10 metre ( 24 foot)
Some ability to fire an AF360 slave flash on a stumpy tripod close in.
Any advice will be appreciated - which film iso is easiest for the first try ?
