How To Go Pro
How does a photographer get his or her work published in magazines and shown in galleries? I use a Canon Rebel digital camera. Would it be possible to have my work critiqued by a professional photographer?

How to go pro is a question I hear at least once a week. The short answer is that you have to make a serious intellectual and financial commitment to photography to become a professional. What’s the definition of commitment? You’ll need professional equipment, professional instruction and lots of association with other photographers who are aspiring to or have achieved professional status in the field.

There are a number of organizations that will help you get started. Join a local camera club. Choose an active club that has frequent competitions and brings in professional speakers for seminars and workshops. Join the North American Nature Photography Association (NANPA, www.nanpa.org); at their annual meeting, you’ll have opportunities to learn more about taking and marketing images and have your own work critiqued by a professional. Another group that focuses on instruction and advancing members skills is NAPP, the National Association of Photoshop Professionals (www.photoshopuser.com). Both organizations regularly issue helpful publications to their members and sponsor regional workshops as well.

Once you’ve established a body of images or produced an article at a professional level, you can submit it to magazines that publish similar work. The number of galleries that specialize in photography is diminishing, and this says something about the market for fine-art photography. However, once you have a group of professional-level images and have identified a gallery that might be interested in them, there’s nothing to stop you from presenting a portfolio for consideration.

Another way to showcase your photographs for sale is through craft shows, but it’s a difficult way to make a living. You need to do your research and see what’s selling at shows in your area. Often, the quality level is quite high and the competition is steep.

Many photographers have made their own gallery on the Internet to showcase, and hopefully sell, their work. There are billions of pages on the Internet, and everyone is facing the difficult challenge of getting viewers to come to their site. Another possibility is to consider marketing your images on one of the many sites that feature and sell image stock. But that’s for another column.

Waiting For Long Exposures
I’ve been taking some star-trail pictures with my Canon EOS 5D with the Long Exposure Noise Reduction set to. It takes just as long as the exposure to process the image on the camera using noise reduction. I’m wondering if the speed of the memory card has anything to do with how long it takes for the image to finish processing in the camera. Would the newer, ultra-fast UDMA cards help?

You’re right. The amount of time the camera needs to process the image in its noise-reduction software is equal to the exposure time. The camera actually takes the image twice, once for the image and once with the shutter closed to compare where the noise shouldn’t be in the image version. This kicks in at 1 & 2 sec if you have the noise reduction set to Auto. For this reason, only use the camera’s noise-reduction mode if you really need it (and astral photography is one of those times) because it’s usually faster to deal with the noise reduction in your image-processing software. With that said, be aware that the computer noise-reduction software won’t give as good a result as the in-camera processing.

The speed of the CF card has nothing to do with the noise-reduction process. However, once the data is ready to be recorded, a faster card works well faster with one important condition. In the recording of data, there are two limiting factors: the card and the camera. Only the newer cameras are able to transmit the data as fast as the new cards are able to record. The EOS 5D doesn’t use the new UDMA technology. The Canon EOS-1Ds Mark III, the Nikon D3 and D300, the Sony Alpha and the Olympus E3 are the first advanced digital SLR cameras to use the faster UDMA cards. The real advantage of the new UDMA cards is seen more in the downloading of the images and not in the capturing of the images, even though these cards are usually rated at 300x in writing speed. It’s all part of the continuing saga of trying to keep all your equipment up to date and in sync.
