Setting Canon- flash as main light

[Steve Bein]

I have forgotten the method. Any suggestions or reminders will be appreciated.
Thanks,

Hi Steve Set the camera on Manual under exposing the subject Flash has to do all the work. If you fire a three images rapidly will see the difference.

Thanks,
I have been putting things on ebay and wanted to use flash as main light for them. It was not working. Usually, I only use fill.

...will give you a lot of glare Steve Best to use natural diffused light or shoot through a diffuser.

Hey Steve,

If your shooting inside just set the CAMERA TO MANUAL MODE and the shutter speed to 1/250. Thereafter, pick an f/stop for the desired DOF. The flash will be greater than the ambient, making it a main source.

Best,

Chas

Thanks, now what about flash as main light outdoors? Like when actually want the black background instead of background showing?

[Charles Glatzer]

Steve,

You can make a background black if you light and expose the subject about 5 stops over the ambient background. Example- ISO 100 sun lit butterfly ambient exposure 1/400 @ f/8, and change to f/22 (3 stop) @ 1/1600 (2 stops)...under-exposing the ambient by 5 stops. Use flash @ f/22 to illuminate butterfly. Of course you have to work within the distance range of the flash to provide the necessary f/22 pwr output.

If the subject is light/dark adjust the flash output, if the background is light/dark adjust the shutter speed.

You really should take the Tech Series ;).
