Macro Ring Flash
One of the biggest problems faced by those who used macro photography is lighting. Because you are going to be work at high levels of magnification and at the same time very close to your subject, you are going to find that there is not much in the way of available lighting.
If you have a camera that has a built in flash, you will find that it does not help very much, neither do those clunky hot shoe flash units. The best solution to the problem is the macro ring flash.
The macro ring flash is considered to be one of the most popular ways of overcoming the lighting problems associated with macro photography.
This is an attachment that fits on the end of your camera lens and most often has two small fluorescent bulbs in it. These bulbs can be adjusted for brightness to allow you to get the right amount of light for the picture you are taking. The fact that the light is directed at the item or area you are taking a picture of makes this type of flash very effective in many fields.
The original macro ring flash was invented by Lester A. Dire in 1952 as he was trying to find a better way for dentists to be able to take photographs of their patients’ teeth. Today the ring flash is often combined with a second flash unit, to provide full backfill as well as directed flash and produces a picture that is not affected by glare.
When you are working with teeth, the risk of glare is high and any glare can make it all but impossible to see the patient’s teeth well enough to make an accurate diagnosis. The modern macro ring flash used TTL or through the lens metering to communicate directly with the power supply and control unit to adjust the level of flash to suit the particular application. The ring flash is used to provide a more all-around lighting effect without shadows. This allows the dentist to look at each tooth for signs of damage or decay.
Fill flash from the attached mini flash is actually used to provide shadows that will allow the dentist to look at the contours of the patient’s teeth so that he can work with them to create the perfect shape and alignment, giving them a winning smile.For the dental world the macro ring flash combined with a mini flash has made it possible to take a full range of highly detailed photographs.
These pictures can be used to help rebuild dental work, replace damaged teeth, check the alignment and installation of braces and many more things. Dire Corp. invented the first macro ring flash and have been in the business of creating dental cameras for over 50 years. You will find that their equipment is second to none, in fact they are a leader in the industry and set the pace by which many other companies struggle to keep up with.
