It is somehow true! For a moment, forget about the live view and consider the case of long exposure. While long exposing, the sensor heats up and this will cause the infamous background noise. So in reality sensor over heating can cause the noise and what happens is that in low light, warmed pixels detect light when there is none. (This last sentence is very ...

Having the battery in the camera shouldn't make a bit of difference if the camera was turned off. I'm also not aware of any particular reason that the scanning equipment should have caused a problem, but what you are describing sounds like a dead or hot pixel. This is just something that can happen on cameras unfortunately. It's also possibly some dust on ...

I am not sure if this has been mentioned before, but last Fall, when I was shooting into the Sun with my T2i, the camera simply shut down during one of the shots (I was lazy and using one of the auto modes). It took about a minute, and it was back up taking pictures.
I trained my film camera at the sun, composing the same shot, and as always, had no ...

Why does a bigger sensor lead to a shallower depth of field?
In simple terms: It doesn't.
If you used exactly the same lens, and only changed the sensor size, you would not get a shallower depth of field with the larger sensor.
It's only when you change other variables to compensate for the different sensor size that you may get a change in depth of ...

Depth of field is determined by only two factors. They are magnification ratio and fstop. By magnification i mean final prit size versus object size. larger sensors require less magnification to get to a particular print size thus appear to have greater depth of field, but if magnified to the same ratio as the smaller sensor, will prove that that the circle ...
