Nissin MF18 Ring Flash for Dental Photography (Dentistry Photo Applications)
Why Use a Ring Flash for Dental Photography?
Ring flashes are powerful lights that produce illumination evenly around the camera's lens. When a ring flash is used for close-up macro photography, such as intra oral dental photography, it produces a flat, balanced light that eliminates unwanted shadows by illuminating the teeth from every direction.
Ring flashes also produce the power required to illuminate a patient’s mouth while maintaining the depth of field necessary to keep a patient’s teeth in sharp focus. Depth-of-field refers to the depth of area in a photographic image that appears to be in sharp focus.
Why Not Use an LED Constant Light/LED Constant Ring Light?
A ring flash, such as the Nissin MF18, produces a short burst of light that is more powerful (emits more light) than a constant LED ring light. The additional power provided by a ring flash allows for the smaller camera/lens apertures required to produce better, sharper images of all the teeth in a subject's mouth.
While LED ring lights are good for video applications where lower light output it acceptable, they emit only a fraction of the light necessary to photograph a patient’s mouth. LED ring lights are simply too weak to use for intra oral photography where small apertures (f/22 or f/32) are required to produce sharp in-focus images of a patient’s teeth.
The Nissin MF18 is a "ring flash" not a "ring light" (which usually refers to a constant light).
Why Choose the Nissin MF18 Macro Ring Flash?
Camera Compatibility/TTL System Compatibility
Nissin MF18 macro ring flashes are available with full TTL metering support for Canon, Nikon, and Sony camera systems. Ease-of-Use
The Nissin MF18 Macro Ring Flash is extremely easy to use. The controller simply slides intoyour DSLR camera's hot shoe and the ring flash attaches to the front of your camera's lens. Once you set the MF18 to TTL or Auto you can immediately start shooting, and the camera and MF18 will automatically meter your shots to produce accurate exposures.
With a guide number of 16 (meters) the Nissin MF18 is the most powerful macro ring flash in its class. For intra oral dental photography, where the greatest depth of field is required to produce sharp in-focus images of a patient’s teeth, the MF18 delivers the power you need to shoot at f/22 or f/32 with industry standard 85mm or 100mm macro lenses.
The Nissin MF18’s accurate TTL metering, precision manual control, well diffused and balanced light, and consistent 5600K color distinguish it from less powerful macro ring flashes and LED ring lights. For those who want fine control over the MF18's light output, the following TTL and manual adjustments are available:
- TTL compensation -3.0 to +3.0 in 1/3 EV steps
- Manual power from 1/1 to 1/64 in 1/3 EV steps
- Fine Macro power from 1/128 to 1/1024 in 1/6 EV steps
- A:B (left:right) adjustment in Manual or TTL shooting modes
