Sharpening! I see so many images on here, especially portraits that have this intriguing sharpness about them that almost seems unreal. What is the key to getting crisp images? Is there a filter in PS (I have CS2) that is commonly used for this? I have read that aperture has a lot to do with sharpness but how do you decide which F stop is the most effective? Many questions here, hope someone can touch on at least a few. Thanks!

Tack-sharp images are the result of good technique and great optics. "Sharpening" can only help to actualize what's already there.

The use of a TRIPOD is the best you can do to achieve sharp images!

That's so true Thomas... (...part of technique.)

Also, when uploading to websites re-sharpen the image (unsharp mask) after re-sizing your image helps for better results when viewed on the web! Best regards!

Blake, I agree with both Bob and Thomas with regard to technique and tack sharp photos. I am not sure what photos you find "intriguing" with regard to sharpness, but I can say that I find that many, many photos are over sharpened to the point of artificiality. Sharpening is like any other technique, use it to the point it enhances your vision and not one pixel more. Bill

Hi Blake, "I have read that aperture has a lot to do with sharpness but how do you decide which F stop is the most effective? The aperture affects the 'DoF' (Depth of Field; http://en.wikipedia.org/wiki/Depth_of_field), the area in front and behind the focal point that is sharp. Basically: small aperture gives deep DoF, large aperture results in shallow DoF. But you, or your 'AF' (autofocus) system, determine(s) where the focal point IS around which the DoF is 'anchored'. And if your camera has a bracketing function, you can choose later which DoF you like best from a range of exposures with different apertures. Of course the camera's point of view needs to be absolutely identical during those exposures. That requires a rock solid point of view. So most probably tripod work.
