Is this normal?

I did some still life setups last night with long exposures, and this morning when I looked at them on my moniter I notice blue and pink hot pixels EVERYWHERE.

I JUST had my camera serviced (like last month) for several "stuck pixels" that were showing up in every image, no matter the exposure time.

I understand that every camera will have a few hot pixels that will show up during the right conditions (long exposures), but does this not seem excessive???? How do I control this/fix it?

I'll include the full frame and a 100% crop. This particular image was a 60 second exposure, f/22 ISO 200.

Thanks for any help/input!

P.S. Also, could the camera shake be from the mirror? I was using a cable release, so it wasn't from pressing the button...

I had problems like this and contacted canon and they said it was the sensor and it was bad and I had to replace the camera with an upgrade. They told me this can happen to the sensor and not much you can do about it....Good luck...steve

It does seem a little excessive, but then again, 60 seconds is a long time. Other than replacing the sensor (which Canon is unlikely to do), the only thing you can do is to map out the bad pixels. With newer Canon's, there is apparently an undocumented way to invoke the camera to map out the hot pixels. See the post by DDan in this thread:

Regarding the softness of the image, mirror shake will not affect a 60 second image. Any perceived softness if probably due to difraction effects from using an f/22 aperture (I'm assuming that you're using a 1.6 crop camera).

Thank you Steve(s)!

Man, I sure hope it's not a bad sensor.........stomach turns...

As far as mapping them out, I actually did try that when was attempting to fix my "stuck pixels". It didn't work for me, so had to send it in. I was also having some issues with misfocusing. So, $200 later, my focusing issues seem to be resolved but shouldn't they have seen this problem when they were fixing the stuck pixels?

I'll have to do some reading on "difraction effects from using an f/22 aperture".... I'm not familiar with that problem when using a small aperture.

Thanks again,
Erin

Bumping to see if anyone else has had this problem...

Thanks!

The long-exposure noise reduction custom function option may help. It takes a second dark exposure (shutter closed) for the same amount of time and subtracts this from the image.
