Digital Filters I have just ordered a Canon EOS D10 with a Canon 28-135 lens (72mm). Is there a difference between a "digital" lens filter and a 35mm lens filter? The reason I ask is because while researching which filters I want, I see "digital" and "film" listed.

Short answer: No. :) The only real difference between "digital" and "film" filters is what normally is the size and the coatings. The size being 20-42mm for the typical "digicam" and "digital camcorder" filter sizes. Usually 37mm or so. With film and prosumer digital cameras, the filter sizes are in the 42mm+ range. 49mm-72mm is typical. The other difference would be the type and number of coatings to reduce things like Chromatic aberration which is a much bigger issue in digital photography than film photography due to the difference between film based capture and sensor based capture of light. Basically, for your 10D, it is a moot point since you will be using some pricey EF glass which is already coated for high end optics. Filters you would use for "film" and "digital" would essentially be the same.

With digital, no filters!!! Filter in Photoshop. Starbursts would be the only one along with perhaps a UV filter. Digital does not like film modifying filters on the lens.

Answer Part I: I've used filters without incident on an Olympus C2100UZ and on my current Minolta Dimage A1. I'm curious to know what kind of issues you encountered while using filters with a digital camera. Which camera model and filter combo Below, I've listed my experience with filters on digital cameras, whether there was an issue and a workaround, and whether photoshop can be - Polarizing filters: Glare that polarizers filter out cannot be corrected for in photoshop easily(or at all in some cases). The intensifying characteristic of - Color balancing filters: - ND Filters: You can correct for a certain amount of over or under exposure, but in many cases, doing so will also pull out alot of shadow noise. - Macro/CloseUp Lens: This cannot be mimicked in photoshop without serious software cropping and resampling. At which point, your image will lose the actual (end of part I)

Answer part II - Soft Focus Filters: - Intensifiers/Color shifter filters - Starburts/multi-image filters: Basically, they perform the way you would expect them to. No workarounds were required. With photoshop, there are filters you can get - Wide Angle lens filters/fisheyes: One a camera which uses IR autofocus, the wide angle can block the camera's ability to focus. This made the filer/lens unuable on my old Short of applying a spherical distortion filter to your image, you really can't get a "wide" shot effect from just photoshop alone. - ND filters (for long long exposures) Neatimage and other noise removal programs can help, but you'll probably also be filtering out alot of the image as well. : - AWB(Auto White Balance) interference. - Teleconvertors (1.4x, 1.5x, 1.6x, 2x) (End of part II & response) Sorry for the 2 parted answer... the system was complaining that my post was too long. ^_-

Hi Darlene, as others pointed out you don't need any filters on digital camera except special effects filters and polarizer for special situations. Any thing you put in front of your lens will reduce image quality. Best think you can get is lens hood. It will dramatically improve quality of your photos for lest amount of money.

Thanks to everyone who responded! This is a great place to go with questions! I'll definately be coming here often now that I'll be taking my photography towards a professional end! Man, I've got lots to learn besides having a "good eye"!
