Strange colour cast with 5D3
« on: May 03, 2012, 02:35:12 PM »
I took these pic in a hall with strip lighting and when I used the silent shutter mode I got a magenta cast and a green cast on the pic. one pic it was magenta at the top and green at the bottom in the next pic this was reversed then the next pix it reversed again. 250sec F2.8 1000 ISO auto colour balance. Did not notice till today so have not had time to try it again.

CFL and Florescent Lighting can cause weird color shifts and banding. It has something to do with it operating at 60hz.

You will see shifts and bands on most shutter speeds except 1/60th and mutliples of it...  this is a well known phenomenon, Not Camera's fault.

In some electronically controlled Ballasts, it could be as high as 1200Hz or 1/1200 to be visable... you just need to know to us ethe right counter acting shutter speed.

Also in video / LV, you will see a rolling bar(s) moving across the screen...
