Mastering Daylight Fill-in Flash in Costa Rica

Today we talked about mastering your flash - for flower photography, which is basically the same as mastering your flash for people photography.

Here is the basic concept for daylight fill-in flash:
• Put your camera on Manual exposure. Don't use a shutter speed higher than 1/200th sec.
• Set the exposure for the background.
• Turn on your flash.
• Set the flash to TTL.
• Adjust the flash output to properly illuminate the subject.

Sure, you might get a decent flash exposure if you set your camera on the Av mode and flash on TTL. With this technique, however, you can control the background light independently from the light from your flash.

I will go into more detail on this technique in a future post. Gotta get back to shooting.

This is just one of the techniques I teach on my Master Your Flash workshop in Croton on Hudson, NY.

Explore the light,

I tend to do that with the built-in flash on the 7D for outdoor macro photography of bugs. I normally need the additional front light, and I can use the internal flash settings to dial down the flash so I get the additioned light for details without overpowering the subject.

Thanks Rick, I always find use of the getting the flash just right the hardest part of photography. I used to use AV mode and then use an exposure adjustment for the background, but Ill try shooting fully manual.
