I have a nice view of a tidal river and am considering taking a timelapse of the view for a day which would involve sunrise and a couple of hours of exposures with the sun in the image. I'd set the camera up in a window and automatically shoot with my computer. The tidal range is dramatic as the river at high tide is a mile wide and at low is 100 feet wide. I have done some test test runs on a cloudy day but that gives much less interesting shots. Ideally a mix of clouds and sunshine and shooting every two or three minutes would produce a set of images. <P> I'd be shooting with my 30D with either a 50mm f/1.8 II or a 28-135mm IS somewhere near 50-60mm.<P>My concern is about possible damage to the lens and sensor taking that many images of the sun and the lens objective being exposed to sunlight for that long. <P>Another question might be: Can this be done with a camcorder?<P> Thanks for any help.
