To see if there were notable differences between the RAW and JPEG formats when processing underexposed and overexposed images, I conducted the following test. In a series of images, I underexposed the test subject by 1 exposure value (EV), 2 EV, and 3 EV, and then overexposed it by 1 EV, in both...

Photography is in large part about exercising control (or maybe that’s just the excuse I use because I happen to be such a control freak). Since the dawn of photography there has been an effort to control the light, the subject, the print, and all other factors that influence the final pho...

When I photograph birds and wildlife, I often use ISO 400 or even 800. Even though the recent Canon cameras are pretty good at high ISO, there is always some noise, in particular in the smooth, out of focus areas. It is not a problem: with Photoshop, it is quite easy to reduce the noise, and I&#...

The popularity of digital photography has brought many changes to the world of images. One of the lesser known may be the ability to create art out of our pictures, with the aid of Photoshop and an array of plugins and stand-alone programs designed to enhance, manipulate and alter images, all in...
Adobe Photoshop Lightroom is the latest entry in the Digital Asset Management (DAM) arena, released mid-February 2007. Lightroom enters an increasingly competitive field that has had some established players, such as Extensis and iView, as well as some new players like Apple’s Aperture. Wh...
One of the frustrating facts of photographic life with which macro shooters learn to deal is that depth of field drops as magnification increases. When I began trying to capture images of insects, I found that my dragonflies, for instance, could have sharp heads but not sharp tails, or vice vers...
Nearly a year ago Apple announced a major new piece of software called Aperture, which was touted as being the first software devoted to photographers’ entire postproduction needs. Shortly thereafter Adobe responded with a beta version of new software called Lightroom, designed to meet sim...

I’m often impressed by the ability of photographers to remember a tremendous amount of information about their photographs. Quite often they are able to look at an image and immediately recite where they were, what time of year it was, what time of day it was, what lens they were using, wh...

One of the questions I get asked most frequently by nature photographers is how to make the best black and white images from color photographs quickly and easily. Most of the time “best” and “quickly and easily” are mutually exclusive, but fortunately there’s a way...
In July 2004, I wrote a brief article for Naturescapes.net chronicling my transition from color photography to black-and-white and how it affected my perception of the bayou where I live. I also gave a description of my black-and-white conversion and printing methods. Now, at the end of 2006, mu...
Adobe Photoshop, one of the most popular image editing programs for photographers, may appear almost impossibly complex to a new user with its dropdown menus loaded with powerful tools. As a photographer who has used Photoshop for years, I find the more I learn about the program the more I reali...

Taking great pictures never loses its appeal, but every now and then you need to mix things up a bit. I don’t mean finding a hobby other than photography, but rather finding a new way to express your creativity with photography. Many photographers have used multiple exposure techniques to...

Fortunately for most, the Photoshop 8 CS Shadow/Highlight (S/H) tool doesn’t have a confusing name, so it’s pretty easy to understand its purpose. Simply put, the tool allows more precise control over the dark (shadow) and light (highlight) areas of your images.
