help needed with Canon 7D

[Deleted member 30033]

I am hoping this is the right category to ask for some help. I have had my 7D a few years now, and only just recently it has started having a horrible graduated tint with some of my pictures. But with the same lighting I can take another one with the picture being ok. Hopefully I have been able to attach the photos to show you what I mean.

Can anyone shed some light on why this is happening?

Such anomalies can occur in fluorescent lighting and shutter speeds faster than 100th sec. The colour of fluorescent lights varies through the cycle and fast shutter speeds can grab part, but not all, of the "spectrum".

Have you added a filter to the lens? a friend of mine had a similar problem we spent ages trying to work it out and turned out to be the filter especially using flash!! daylight exposures were normal, hth mike.

Agree with Bob, looks like fluorescent light at fast shutter speed. Though that's quite a severe colour shift, I have some short tubes above the kitchen work-tops like that though most are not so bad!

Drop the ISO and raise the f/number to get longer shutter speeds.

Ahh, just checked - green one was 1/350, the normal one is 1/90 - the answer is here! Thank you.
