A common question for those who dont want to shell out the big bucks for Pocket Wizards.? Having owned a set in the past, I can say that they are great for the money, but offer no peace of mind.? They seem to work fine for indoor studio shoots, but are quite erratic in outdoor […]

The Sunny 16 Rule says that on a sunny day the exposure is the reciprocal of the film speed at f16. That’s 1/ISO @ f16.? So say I was using 160 ISO film and the nearest shutter speed was 1/125 so I
added 1/3 stop to line up with the available shutter speeds. This give me […]

The specs say 1/250th for non-FP/ High-Speed flash units.? However, you can usually push it up to 1/320th without any vignetting.? This is helpful when you need the extra speed in outdoor situations. ?

When a lens focuses on a subject at a distance, all subjects at that distance are sharply focused. Subjects that are not at the same distance are out of focus and theoretically are not sharp. However, since human eyes cannot distinguish very small degree of unsharpness, some subjects that are in front of and behind […]

The histogram on the camera is based on a RGB-weighted luminance of the JPEG. There is *always* a JPEG, whether you have the camera set to take JPEGs or not. The RAW file, when you shoot RAW-only, has a 1.5MP JPEG embedded inside of it. The camera has absolutely zero facility for showing you the […]

Teleconverters, either 1.4X or 2X, are efficient tools to add focal length to the photographer’s arsenal. However, universal-type teleconverters have certain limitations in performance when used with ultra-telephoto lenses of 200mm or longer as compensation of chromatic aberration alone becomes highly critical in this focal length range. The new PRO-series teleconverters are specifically designed and […]

What better way than to learn at the Battery University. ?

No, you dont want one.
There was an article about 3rd party grips. A number of grips and cameras were tested. Here was the bottom line:

- All grips send optical trigger
signal to the camera IR sensor through an optical fibre connection. The
cord gets in the way and doesn’t stay attached to the camera.
- Mismatch of color/shine/texture […]

The Kenko 1.4X Pro 300 TC is hands down the winner behind the Canon 1.4x.? Obviously since it is almost twice the price.? The Kenko is superior to the Tamron as reported by independent user tests on DPreview.com.? If you decide to get the Kenko make sure it is the black one, which is the […]

Starting out, people will be either shooting from the shore or from a pier. Shooting from a pier gives you the advantage of being closer to the active part of the wave, but you will be shooting from an angle that is a little awkward, but still can result in intriguing shots. The other issue […]

Have you allowed enough time for the IS to settle
down before taking each photo ? It may not be stable for the first half
second after half-pressing the shutter button.? This is a pretty common problem among first time IS users.

Camera exposure systems are calibrated on the assumption that the overall brightness of the scene will average out to the “18%” or mid-gray found on a gray card. In other words, if you looked at the entire scene in black and white, all the white highlights, midtones, shadows and blacks when mixed together would average […]

Nikon’s image management software, Nikon Capture version 4.4.0 (Windows) is now available for download. The new update adds support for D200 RAW images.
