- They increase background blur of an image (they produce a shallow depth of field)
- They flatten the perspective when photographing portraits
- Not only can they be used to photograph subjects far away, you can produce some really detailed photographs of subjects like flowers and plants using a telephoto lens; the shallow depth of field created by the lens is very effective when photographing these types of subjects.

`When using a telephoto lens, use high shutter speeds and a tripod when possible; this will ensure that the subjects within your image appear sharp and in focus.
By using a telephoto lens, you are magnifying an image, this however means that you are magnifying camera movement as well. Therefore, by using fast shutter speeds and a tripod, you will counteract this camera movement.`
If you are really sure you would like to invest in a telephoto lens, then it would be worthwhile investing in a lens hood as well. A lens hood simply fits onto the end of your lens and reduces flare that bright light sources can create within your images, especially if you are shooting towards the light source itself. For my lens, I have a `Canon ET-65B` lens hood, this works really well and stops excess light from entering my lens, reducing flare.
Next week I will be focusing on `Self Portraiture`, so get your cameras at the ready!
