I am new to digital photography and recently bought a Canon S5 IS. I did a dumb thing with it while inspecting the lense for scratches. I shone a 60 watt florescent bulb on the lense and had forgotten to turn off the camera. In reading through the manual I came across warnings to not expose the camera to bright light sources, point directly to sun, etc. I was wondering if I could have possibly damaged the ccd and how I would know. I am not noticing any problems with my photos. Thanks for the help.
