Digital Photography Tips And Tricks - Understanding The Camera Lens Hood

by Dan Feildman

A camera lens hood is a cylindrical plastic piece, rubber, or metal that fixes over your lens to prevent light from shining directly into it. The hood can screw onto the front of the lens or some hoods are linked to the lens and may slide out like a sleeve.

Initially when I first got my DSLR camera I had no idea what a lens hood was. I bought my camera used from a friend. It had two lenses. One of the lenses had a hood. I never used the lens hood at first. Yes, I had a film SLR camera when I was younger and I should have known what a camera lens hood was, but I don't ever used one hood then either. Eventually I decided to use the hood to see if it made a variation and it did. Now I use my camera lens hood most of the time.

Hoods may come in a variety of shapes and lengths. They are usually cylindrical, but they can also be square. The edge of the hood could be straight or flowered. Flowering of the edge should aid prevent vignetting when the hood is on correctly. Hoods are made for each type of lens. Make sure you use the hood that was made to be used with your lens. If you use another hood you could get problems, like vignetting.

Digital Photography Basic principles - Improve Your Photographs

Lens hoods reduce the shapes and streaks of color that bright light may cause in your photograph called lens flare. But that's not just one thing a hood can do.

Using a lens can also help make the colors in your photographs look richer. It helps prevent you from getting blown out pictures.

If you want to use flare as a creative effect in your photograph you won't use a hood, obviously.

Digital Photography Basics - Protect Your Lens

Since the hood stands apart from the front of the lens the way it does it may aid protect your lens from damage. That's not the aim of a hood, but it may act as extra protection to prevent things in contact with the glass at the front of the lens.

It can also help protect your lens from getting water or dust on the front element.

Digital Photography Basics - Possible Issues with Lens Hoods

Often hoods can cause troubles with your pictures. If your hood is much too large it may block your camera's built-in flash. If that's happening you will see that your photograph is darker at the bottom.

Often you might notice vignetting if you use a specific lens hood. This all depends on the lens your using and the size of hood. Lenses with a wider field of view can't use longer hoods. If you use a hood made for the particular lens your using, you wouldn't have this issue.
