After enjoying this great portrait and lighting,
I can see some more added value to this picture and discussion on the “picture flick thread” (click image to go there.
The first cookie is the method used to remove the light fall off – a bounce card under the camera.
A second cookie is fluorescent flicker discussion on the photo page. O’bran was concerned with flickering of the light caused by the way fluorescent works – they flickr many times a second depending on the current fluctuation in your electricity socket.
The solution to this problem is easy, and depends on the country on which you do your shooting.
The basic principle is to shoot in a shutter speed that is a “full” multiplication of the current frequency. So in the US, where current runs at 60Hz, you need to shoot at 1/60 or 1/30 or 1/15. each of those speed will assure that the camera get an equal amount of light from the different colors of the flickr cycle.
In most European countries the current runs at 50Hz, so you’d want to rake the shot at 1/50 or 1/25 and so on.
Lastly if you click here, you can get a high res image as some has asked in the original thread.
