What is a Ring Flash?
Ring flash is a circular photographic flash that fits around the lens, especially for use in macro (or close-up) photography. Its most important characteristic is providing even illumination with few shadows visible in the photograph, as the origin of the light is very close to (and surrounds) the optical axis of the lens. When the subject is very close to the camera, as is the case in macro photography, the distance of the flash from the optical axis becomes significant. For objects close to the camera, the size of the ring flash is significant and so the light encounters the subject from many angles in the same way that it does with a conventional flash with soft box. This has the effect of further softening any shadows.
Ring flashes are also very popular in portrait and fashion photography. In addition to softening shadows, the unique way that a ring flash renders light gives the model a shadowy halo which is a common feature of fashion photography...as Wikipedia says...
This is actually what you'll get:

As i previously said, i've never used one, but i'm planning to, so i found some useful link on how to do-it-yourself!

In photography, a multiple exposure is when two or more individual exposures are made to create a single photograph.
This is an example of what i did with an Holga camera, which let you shot multiple expoure on the same piece of film!
To do the job, the shutter release of the camera should be independent from the winding mechanism of the film (if we are talking about film cameras) but we can have multiple shots using our imagination and create some cool and dreamlike works.
Basically there are four way of doing that, or at least those are the one i thought on:
1) Buy an expensive Pro DSLR and probably it will let you shot some few times on the same picture.
2) Buy a cheap Holga from eBay
3) Use a software photo editor such as Adobe Photoshop or GIMP, by altering the opacity of the two images and line them up over each other, or set the layers to multiply mode, which 'adds' the colors together rather than making the colors of either image pale and translucent
4) DSLR with an external flash unit
DSLR with an external flash unit
As the title says, we need a dslr unit with a lens (obviously) and an external flash unit for it.
Actually the trick to have multiple exposure is to:
- have a long shutter speed (you need to try it for your best fit, as every environment will require a different long shutter speed)
- use an external flash unit which let you shot the flash by pushing a button
Target the subject of your picture, shot it with the flash on (as a normal shot with flash), and then move quickly (it depends on how long is the shutter speed you are using) on another subject and just press the button of your flash unit to flash for a second time.
We will get a double exposure picture, because the automatic flash on the first shot, freezed the first subject, then the manual flash will freeze a second subject.
Actually you can have multiple exposure even with a single flashing light if the subject is in good light condition.
That's what i did
