Further Techniques

• A multiple exposure is when two or more images are combined together to create one single image. Although it looks complicated, as long as it is planned well, it is quite easy to produce. There are many different reasons why people choose this technique such as trying to create a ghostly effect, a mirrored effect, or simply to merge a moon into a sky. More complicated exposures, like the ones to the left, are done for a fine art purpose to create world that cannot be possible.

• Multiple exposures first started out as an accident when using a film camera but now-a-days artists use Photoshop to create these images a lot easier and for a purpose. To create a double exposure with a film camera you have to take a picture, then hold the rewind button, advance the shutter, release the rewind button and take the next picture. Then they will be developed together.Most people create double exposures digitally now. This consists of you taking your images, uploading them onto Photoshop and layering them over the top of each other and adjusting the opacity.

• You will need access to Photoshop and a digital camera and a tripod to create multiple exposures.

Multiple Exposure

• High speed photography records fast moving objects that are normally invisible to the human eye.

• Scientists use high speed photography to study physical movement and gravitational effects. The military uses this technique to look at missile and rocket accuracy and to record what is happening at the core of a nuclear explosion. It is also used in sports photography such as tennis, biking, racing and horse racing. It is popular for artists too and this work would be shown in galleries.

• Firstly the aperture and shutter speed needs to be altered. The shutter speed needs to be as short as possible (1/800 second), and the aperture needs to be large (F14), this will help capture the image quickly and still have enough light to be captured. It is crucial that you have a totally dark room. If there is any light in the room, there will be some exposure on the frame which can appear as blur in the final image. But a high flash will need to be used to light up the object when the shutter shuts.

• You will need camera with manual controls and a flash available. You will also need a tripod and if you need to edit your image after you will need access to Photoshop. Post production isn’t usually common with high speed photography but colours could be brightened and sharpened.
