Hi everyone,

this is probably a little bit off topic, but since this is the best audience of camera/imaging experts I know I will try to ask here...
I was trying to use ImageJ to acquire images of my gels/plates that sits on transilluminator (both white light or UV) and I realized that when I try to do that a strange pattern of lines appears on the image. Initially I was thinking that the reason was that I was using a very cheap CCD (a 10 $ webcam), but the same pattern appears if I take a picture with my phone camera. The pattern seems depending on the chip, because if I turn the camera it turns as well. Does any one have an explanation for this? More importantly there is a way around it.
The idea is essentially to image directly on my computer without using a 10 K$ expensive gel doc

Thanks a lot

Max
