Nikon D90 Flash

Nikon D90 flash is a very good flash and will serve you for practically anything you would need and for any situation. It functions in 5 different main modes so you can always adjust it to your needs. These five modes are Front Curtain Sync and Back Curtain Sync, Slow Sync, Red-Eye Reduction mode and Red-Eye Reduction with Slow Sync.

There are some main differences in these 5 different modes of Nikon D90 flash. The first one, the Front Curtain Sync is good to use when you want flash to fire before the exposure with each shot you make. The Rear Curtain Sync is great for making light effects around people. It will fire flash at the end of the exposure making the image appear as if the light trail follows your subject.

Nikon D90 flash has also Slow Sync mode which is used to preserve the natural colors of the items shot in the dark. This is accomplished with slowing down of the shutter speed to up to 30 seconds. To make the pictures of people in the night look pretty and without red-eye effect, you will probably use Red-Eye Reduction mode. The Red-Eye Reduction mode works by firing high intensity AF-assist light right before the main flash. This way peoples eyes are already ‘filled with light’ or better to say prepared for the main flash and the picture results are great. The difference in Red-Eye Reduction and Nikon D90 flash Front Curtain Sync is in that very bright light fired before the main flash.

The last, but not least mode of Nikon D90 flash is the Red-Eye Reduction with Slow Sync. This mode works very similarly to the way Red-Eye Reduction works, but it is combined with a slower shutter speed. This in return creates nice effect that gives you nice surrounding light visible in your picture.

To use any of the modes available you need to pop out the flash otherwise it will be disabled and you will be able to take flash free shots. Of course Nikon D90 flash has a lot more to offer then just five modes. You are also able to adjust the flash brightness from +1 to the -3 EV or go full manual and get even more.

Nikon D90 flash is truly made to give you all you need. Using the automatic flash modes you are able to get 12 meters of very high quality (at ISO 100), but if you feel like having more, just go manual and get a bit more than 13 meters at the same ISO 100.

With its speed of 1/200s the Nikon D90 flash is truly capable of getting you amazing results and if you feel scientific or looking for more effects it is easily done by extending it with optional external speedlights.
