Understanding Camera Lenses. Understanding camera lenses can help add more creative control to digital photography. Choosing the right lens for the task can become a complex trade-off between cost, size, weight, lens speed and image quality.
This tutorial aims to improve understanding by providing an introductory overview of concepts relating to image quality, focal length, perspective, prime vs. zoom lenses and aperture or f-number. All but the simplest cameras contain lenses which are actually comprised of several "lens elements. " Each of these elements directs the path of light rays to recreate the image as accurately as possible on the digital sensor. The goal is to minimize aberrations, while still utilizing the fewest and least expensive elements. Optical aberrations occur when points in the image do not translate back onto single points after passing through the lens — causing image blurring, reduced contrast or misalignment of colors (chromatic aberration).

I’ve never been fond of the canned effects they produce. I prefer a less conventional, more realistic approach. But if you’re still looking for such a tutorial, hit the checkout stand and try this one. The technique I’ll introduce is a completely proprietary one, developed after years, er months, er, I give — it only took a few hours to produce the technique. Yet it really is a bona fide proprietary one.
Alas, I settled on a blatantly descriptive, no-frills name: The Sharpened Blur. The Sharpened Blur Shouldn’t require a manual to explain how the technique works. Here goes. Step 6 – Done.
