     With CCD and CMOS chips as photographic mediums, what normally is expressed in film as a nearly continuous range of color and tonality is typically reduced to 256 levels of brightness for each of three color channels. Thus, though digital photography brings with it an amazing degree of flexibility, we begin with much less information than we would have had we used film. We must therefore apply a different set of techniques to get the best out of our cameras. This website is aimed at providing technical information in a no-nonsense manner to amateur photographers who wish to maximize their results in the age of digital photography. Of special interest to me are the differences between perception and the photographic image and how to make the photographic image more representative of perception using both traditional and non-traditional methods.

Apply more than one custom tone curve to your Nikon D300, D300s, D3000, D3100, D5000, D700, D200, D80, D90, D100, D70(s), D50, D40, D40x, and the new D7000 images!

Until now, one of the limitations of custom tone curves was that you could only apply the curve that was loaded in your camera when you took the photograph. Peter Dove and Iliah Borg just recently created a program called Curve Surgery that allows you to apply additional custom tone curves to your images. Check it out!



How to improve Nikon D300, D300s, D3000, D3100, D5000, D700, D200, D80, D90, D100, D70(s), D50, D40, D40x, and the new D7000 tonality using custom tone curves

One feature that some D-SLRs have is the ability to use custom tone curves.  Find out what they are and how to use them in the Nikon D300, D300s, D3000, D3100, D5000, D700, D200, D80, D90, D100, D70(s), D50, D40, D40x, and the new D7000.


How to choose the perfect lens using MTF charts

Although MTF charts cannot foretell the future, they are pretty good at predicting how sharp a lens will be.  Learn how to choose the sharpest lens for your needs using MTF charts.



Why the 3:2 aspect ratio of 35mm film is not simply an arbitrary standard

Recently, I came to the realization that the 3:2 aspect ratio of 35mm film may not merely be an arbitrary ratio. Read about how Leica and Henri Cartier-Bresson fit into this discovery.


Landscape Photography

Of all the places I've been in the world, few compare in beauty to California's Central Coast. In between my studies at the Naval Postgraduate School, I have been photographing the lush area around Carmel and Big Sur. In many of my photographs, I use a technique whereby I blend several exposures of the same scene. Take a look at my gallery.



Many thanks to Joshua Dearing for hosting this site!

Without his generous contribution, none of this would be possible. Check out his fresh website with lots of photos.


Action Photography

Check out my gallery of surfing action photography. In many of the photos, you can see Pebble Beach Golf Course behind the surfers. If you look carefully, you might even be able to spot Tiger Woods!
