Oh Thanks Hetty!
I've used the most powerful and largest light I had, the sun ;)
If you get the sun in a 45 angle around mid-morning or mid-afternoon you'll get a good bounce if you place a white sheet or whiteboard in front of your subject.
For the background using a black sheet worked for us, if somehow that black backdrop can be in the shade even better as it will be easier to make it black without pushing the shutter speed to high.
I decided to use a telephoto lens to compress the background.
Model: Canon EOS 7D
Lens (mm): 300
ISO: 800
Aperture: 5.6
Shutter: 1/1600
I found the video that I mentioned in the post...
I hope this helped you Hetty!
Cheers
Gaston
