Becoming a digital photography pro isn't difficult


Creating a photo-friendly environment in each room is simple; all that's needed is proper lighting and background.

"In my 21 years of practice I have made a constant observation of countless doctors I know from all specialties of medicine and dentistry... the best doctors take a lot of pictures! (And) they don't just take the pictures, but they make their images work for them," Dr. Niamtu says.

Stop stalling Dr. Niamtu, who practices cosmetic facial surgery in Richmond Va., says though many doctors have left slide photography behind to embrace the new technology, there are still some who haven't. His message to them: Get with it!

The quest for a digital camera doesn't need to take on Homeric proportions.

"Most high-end, off-the-shelf, name brand digital cameras will suffice for most clinicians. Most of them have adequate macro function for close-up images and can zoom out enough for full body pictures.

Because simplicity is key to prolific documentation, he also recommends checking out any reputable professional camera company that modifies the camera software and flash to simplify macro flash photography. For close-up photography in the macro mode, a standard flash may not suffice. The flash set up on off-the-shelf cameras is too close to the subject in most macro situations and will not illuminate the area. Lens mounted ring or point flashes will solve this problem, but purchasing a factory modified camera can produce the same results without bulky or add on flashes.

He adds that the camera should be simple enough, with automatic settings, so staff members can pick up, point and shoot during in-surgery photo ops when the surgeon is scrubbed and otherwise unavailable to take photos. Also, look for a camera small enough to throw in a briefcase to take anywhere and use at a moment's notice.

Resolution requirements Ten years ago, digital cameras had a grainy 640x480 resolution; today, the technology has exploded, offering upwards of eight megapixels. The resolution relates to the actual size of the image, Dr. Niamtu explains. So how much resolution is enough to produce great images?

"One misconception is that you constantly need to upgrade to higher megapixel cameras," Dr. Niamtu says.

"Granted, the higher the resolution, the better the picture, but cameras are like stereo equipment in that after a certain point the differences are miniscule ... Personally, I feel that there is no need to take eight megapixel images for routine digital clinical photography. You just don't need that size and these image files are very memory-intense."

Unless the images need to be significantly enlarged, super-high resolutions aren't necessary. A four megapixel image is sufficient for printing larger than 8x10 and big enough for publications and PowerPoint presentations without taking up too much hard drive space on the computer.
