f8 all the time? Alright, play with the aperture, that is the setting which controls exposure, not the shutter. Even full power flashes have arc durations of ard 1/1000th sec max. 1/8 may have as fast as 1/5000. There is probably no difference between 1/100 and 1/1000th of a second on your cam at low ISOs and f8 with your indoor environment.Originally Posted by Del_CtrlnoAlt
An extreme eg would be in a totally dark room. You can expose for 100 seconds and the flash exposure for 1/1 power would still be same as a 1/1000s exposure. Shutter controls ambient, aperture controls flash, you control the ratio with both.
HPtay, you may want to try using those white LED torchlights. Eastgear selling a nice $25 one with 9 LEDs but uses CR123. Bleah.... That homefix shop in Centrepoint 3rd story sells a 8 LED unit which uses 3AAA, costs only $19. Buy 2 or even 3! Very good for macro work.
