Hi folks,
Not sure how relevant this is but thought it might help people getting a bit of a handle on off camera flash. It'll be basic for some but useful for others
All done in full manual (flash and camera) with one old sb28.
I've been playing with my pocket wizards again just experimenting with exposures with one flash off camera and some light coming in from the window. This was quite a quick setup in the living room with no clear backgrounds, I have done a shot to demonstrate what was in the background (a couch!). I didn't have any willing subjects so I had to use my wii guitar.
I think ambient exposure was about 1/100 at 2.8 ISO400. From this I can now choose if the background can be blown out white or Black, obviously for a white background there also needs to be something lighting your subject or you would get a silhouette, in this case the light came from the window.
So to blow out the background I had my flash pointed at the ceiling at 1/4 power, my camera set to 2.8 ISO400, 1/200sec, the window light exposed the guitar and the flash blew out the background.
Now to make the background black I had to eliminate all ambient light so I set my camera to 1/200 (I couldn't go any quicker as this is the 5D's x-sync speed) ISO100 and f16. The drop in ISO and aperture would also reduce the effect of the flash. The flash was now lighting the guitar, it was still at 1/4 power but I set the zoom (on the flash) to 85mm to reduce the spread and had it coming in from about 45 degrees to the right, this was important as I didn't want any spill onto the background, not to mention the horrible sharp shadow it would have produced. Instead of increasing or decreasing the power of the flash I just changed the distance between flash and subject and thats about it. I did a very minor tweak in lightroom to ensure the blacks were black and the whites were white but nothing else.
