I am seeing debris on my digital images. I am seeing dust/debris on my images. I don't see them when viewing them in the camera, but I do when viewing the images on my computer. I keep my lenses and filters clean. Is there a easy afforable way I can tell where the problem lies? Is the debris in the camera or in the lens? I am assuming that a pressurized air duster is a bad thing to use. Thanks in advance for any advice. RJL Photography

Hello Rachel, There is a good chance what you are describing is dust etc on the sensor cover. Posting a photo would really help analyze this. One of the easist ways to determine this is as follows; Take a picture of the clear blue sky, don't worry about focus; you probably can't focus anyway, so set it on manual. Next, in Adobe or whatever software you use, over and underexpose the image greatly using levels. If you have dust on your sensor cover, it will become quite apparent; especially when looking at it underexposed with levels. This is the photo I'd like to see to determine if this is indeed a dust prob. High pressure air is a bad idea. If a bulb type blower can't clear away the debris, your next step will be manually cleaning with specialized products. al the best, Pete

Here are two photos that show the problem. I did as you suggested and greatly overexposed one of the copies.
