I photographed the bill and breast feathers of this Dalmatian Pelican at Lake Kerkini, Greece on Monday afternoon with the Canon 70-200mm f\/2.8L IS II lens, the 2X III TC, and the EOS-1D Mark IV (hand held at 365mm). ISO 400. Evaluative metering +1 2\/3 stops: 1\/125 sec. at f\/16 in Manual mode. From the boat. Fill flash at -2 stops with the Better Beamer. <\/p>\n

I used flash here to help sharpen the image. I knew from experience that I needed to stop down for additional depth of field to get the feathers sharp at close range. I rested the bottom of the camera on the gunnels and the barrel of the lens with my left hand. The great four-stop IS on the 20-200 II helped me to produce a very sharp image at a relatively slow shutter speed.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

Better Beamer Basics<\/h3>\n

The Better Beamer, developed many years ago by my friend Walt Anderson of Chicago, is a device designed to roughly triple the output of your flash when using telephoto lenses with focal lengths equivalent to 300mm or longer. (Your calculations should include the multiplier effect of your camera.) <\/p>\n

Using the beamer will increase your flash output 2 2\/3 stops and allow you to photograph at greater distances with smaller apertures. It folds flat, sets up quickly and easily, weights just 2 1\/2 ounces, and holds the Fresnel screen in place with no sagging or flopping. <\/p>\n

Most importantly, using a Better Beamer reduces battery drain and allows for faster recharging. If you own a Better Beamer and are working with a long telephoto lens, not using the beamer makes zero sense as you are simply wasting battery power. Your flash is designed to shut off when the desired exposure level is reached. A Better Beamer concentrates the light from the flash thus allowing the flash to shut off faster. Less light is wasted than if you were not using a beamer. (The beamer offers approximately 300mm lens coverage so with longer lenses you are still wasting a bit of light.) <\/p>\n

BIRDS AS ART currently offers six different models that fit virtually all Canon and Nikon flash units as well as the flashes of a variety of other brand flashes. You can learn more here<\/a> or call Jim at the office at 863-692-0906 with your flash head dimensions to find the right Better Beamer for your flash. <\/p>\n\n\n\n

Here I am using the Better Beamer on my 800 on a cloudy day in San Diego. This image is courtesy of and copyright Becky Field. <\/p>\n<\/td>\n<\/tr>\n<\/table>\n

I often receive e-mails from folks asking how to use the Better Beamer. After I read their e-mails it becomes apparent that they simply do not know when and how to use flash. The beamer just gives you a more efficient tool. If you are filling a bucket with a hose and the bucket has a shut-off device that stops the flow of water when the bucket is full, it does not matter if you are using a thin hose or a thick hose. All that the Better Beamer is is a thick hose….<\/p>\n

First I offer them the basics of using flash: I often use flash (and thus the Better Beamer) on cloudy days and in overcast conditions to help eliminate the usually blue color cast, to render the bird’s feathers a bit sharper, and to add a catchlight to the subject’s eye or eyes. And I sometimes use flash on bright sunny days to reduce the shadows and even out the lighting. (Note: on sunny days I may set the flash to zero or even to +1 stops yet I will still be using the flash as “fill.”)<\/p>\n

In each of these situations I am using flash as fill. I first set the correct ambient exposure and then reduce the power of the flash from 1 to 3 stops by dialing in -1, -2, or -3 stops (or something in between). I use very little flash, -3 stops for example, when working at very close range. If the flash fails to fire, the exposure will be fine as you have set the correct ambient exposure. <\/p>\n

Most intermediate photographers will want to learn to use flash as main light when working in very dark conditions such as at a swallow nest under the eaves of a house. If the flash fails to fire the image will be black. At times, advanced folks may opt to work in Manual flash mode either when working with fill flash or with flash as main light. <\/p>\n

At his point I gently suggest that if they wish to learn to use flash that they consult the “Flash Simplified section in The Art of Bird Photography II <\/em><\/a>(916 pages on CD only). <\/p>\n

If you don’t know how to use flash and you purchase a beamer, you still will not know how to use flash \ud83d\ude42 Once the beamer is in place, you use flash as you always would. Nothing changes. The beamer will simply let you work with flash more efficiently and save you lots of battery power. I tell them that I would love to rewrite the whole thing section on flash for them and teach them how to use flash from the ground up but that I simply do not have the time. Plus, I like to sell a few CDs every now and then. <\/p>\n
