Getting a weird "Blueish" Tint

[tjcamro]

When I have been out taking night photos lately I have noticed that I am getting a blueish tint on the top right and left hand corners of my photos. I ran the sensor clean on the camera and I am still getting the issue. I tried it with 3 different lenses and still the blue tint shows up.

Any ideas what the issue could be?

I have a Sony Alpha 100

Don't know.

Could you post an example or 2? That might help someone figure it out.

If you have cheap clear filters on the lenses it could be the cause, please show examples.

I took the filter off and still got the same result. I would love to add a photo but my internet is so terribly slow it never works on here.

How long were these exposures? If we're talking exposure on the order of a minute or more, it could be "amp glow". Amp glow is caused by part of the sensor picking up heat from neighboring electronics, and is more noticeable in cold weather. From what I can tell, the Sony DSLRs (and their Minolta predecessors) seem to have a history of amp glow problems.

Here's a posting of amp glow on an A100:
