Picture taken with the lens caps on, ISO = 400, exposure = 1", has red dark specks of 3x3px size
Hi All!
Two weeks ago I get my new CANAON EOS DIGITAL REBEL XT 350D. Accidentally a made a shot with the lens caps on. The last picture should be black, but, to my surprise, there was a group of dark red specks in the image. I did more images with different ISO/exposure settings (RAW format), but the speck group didn't disappeared. Its appox. size is 3x3px. The non-black pixels are arranged in the following way: 1-2-1 2-3-2 1-2-1 where "3" means the brightest pixel, and "1" means the dart-dark red one. I was thinking it could be defective sensor, so I contacted the support. They recommended me to send the camera to one of theirs support centers "...to be examined...". . Now I want them to look on the pictures because don't want to send the camera unless I'm sure the problem is with the sensor and they agree on it. And the reason I'm writing to the conference is, that maybe someone has had such issues and he/she could share the experience... It also will be interesting if someone will test his/her camera in the way I did. I have my images uploaded and they are available on Inet: 1. Picture taken with the lens caps on, ISO = 400, exposure time = 1" http://www.mysharefile.com/v/2957648/img_2911.cr2.html 2. Picture taken with the lens caps on, ISO = 400, exposure time = 10" http://www.mysharefile.com/v/8143079/img_2910.cr2.html 3. Picture taken with the lens caps on, ISO = 1600, exposure time = 1" http://www.mysharefile.com/v/7246556/img_2912.cr2.html I also can post my correspondence with the support if interested. Thanks, Sergey Adamenko Houston, TX |

Thanks the answer!
I've read about mapping. Wish Canon provided a tool in to mark hot pixels, so that clients can resolve such issues yourselves. Sergey. |
