Lighting test - gridded beauty dish with blue gel back light
Spent a couple of hours on Saturday with fellow photographer Luna testing out colored gels.
I have a feeling that this blue back lighting is pretty standard in the laboratory scenes of C.S.I. Las Vegas. (I think they also tend to put a green or yellow gel on the main light.) The above image was desaturated slightly in Photoshop.

Hi,
Have you tried using an iPad as a preview tool?
Just done my first test using a Eye-Fi card and my iPad – oh, you need a WiFi network, too and a small app called Shuttersnitch! If there isn’t one where you are you can buy a portable, battery-powered, WiFi router and just shoot away – each picture will be almost instantly in your iPad, which you can carry on your back, if you want to, with its screenturned off! Amazing!
I have as yet just tried it at home, but my isn’t this amazing!

No IPad at the moment, but I am considering getting one when the new version comes out in the next couple of months.
I saw a friend using an Eye-Fi card and it seemed to work well as long as you were only try to send smaller to the computer. When you sent larger files it took a while for them to appear, so it didn’t really work as a preview. I think it would work if you shot RAW on the first SD card and small jpegs on the Eye-Fi. Then preview and check lighting and composition on the ipad screen, but then edit from the full size RAW file.
Will check out all the information in the link later after I have made some coffee 🙂
