Get that flash off camera and all sorts of possibilities open up. Front light, back lit, side light. Its all breezy! These are some quick examples on lighting, straight out of the camera this morning. The Columbines opened up in our pot outside the store, so I grabbed a few.
No flash, available light. Not bad.
A little OCF action.
Again, available light.
And a little remote, off camera flash
And some flash pop.
I put my camera in CLS mode with the flash set to TTL hand held. Moved it all around the flowers for different effects. With the camera locked down on the tripod, you can really see the effect that moving your light around has.
