Tricks of the Trade
awild | February 1, 2008My early bug photos, the ones I don't show anyone anymore, are poorly-exposed affairs that now sit hidden in my files. If I had to put my finger on the single biggest problem with these embarrassing first attempts, I'd say that I lacked an eye for composition. I was so intent on getting the bug in focus somewhere in the LCD that I paid no attention to what else ended up sharing the frame. Turns out, all sorts of extraneous crud. Bits of grass. Dust. My finger. Many of these images are so crowded that it just isn't clear what I ought to be looking at.
Understanding why busy compositions…
awild | January 28, 2008Last week I performed my semi-annual copyright registration ritual, and in the middle of the paperwork it occurred to me that this might make an absolutely scintillating blog post. So, here's why copyright registration is important, and here's how to do it.
U.S. law is generous towards photographers. Photographs are automatically copyrighted as soon as they are taken. It doesn't matter if you're taking happy snaps of your pet cat or professionally shooting a Hollywood premiere- you have the copyright.
What does having a copyright do for you? Not very much, it turns out. If you'd like…
awild | January 9, 2008People occasionally ask why I don't assign my photos a Creative Commons license. Dan Heller explains. And adds a horror story here.
The short of it is, while Creative Commons was established with the best of intentions it is easily abused in the photographic setting. Users unknowingly open themselves up to large legal risks, and I find photo licensing by traditional means to be both more secure and more professional.
awild | December 29, 2007Photos posted to myrmecos.net rarely go straight from the camera to the web. Through some combination of errors related to exposure and the innate properties of digital sensors, raw images can be a surprisingly poor match to what is seen through the viewfinder. Raw images are often relatively flat in appearance, with colors that are shifted or off-hue. For instance, Canon cameras by default impart a warm reddish hue to their files that is especially apparent in macrophotography. The nice thing about raw files, and indeed the main reason for using them, is that they are malleable enough to…
awild | December 9, 2007Flash is a necessary evil in insect photography. This necessity is due to two unfortunate traits shared by most insects: small size and stubborn unwillingness to sit still for the camera. These traits confound each other in a way that renders insect photography uniquely challenging. Small subjects need to be close to the lens, placing them squarely in the zone where depth of field becomes razor-thin. Depth of field can be increased by using a small aperture, but that restricts the amount of light reaching the sensor. With so little light entering the camera, a proper exposure requires…

A few months ago I started playing about with the placement of the flash unit, and almost immediately hit on a new favorite trick. When lit from behind, insects look even more zingy than usual. Their translucent bodies glow, they are ringed with little halos, and they stand out dramatically against the background. Below the fold are some samples:
Backlighting involves two major elements. The first is a relatively high-intensity light shining directly on the subject from the opposite direction of the camera. This light gives translucent insects their glow and provides the halo…
