The second in our focal length explained series. The focal length of your lenses is a treasure trove of creativity. Just by zooming in or out you change focal length and as you do you alter your field of view, depth of field and perspective at the same time. By understanding how focal length changes the way an image looks - you can begin using the effect creatively for mor dynamic compositions and dramatic images.
When I learnt this (and trust me - it took a while and a lot of practise) my image making leapt forward in leaps and bounds. Now I use these techniques everyday in my work as a pro photographer. So what am I on about....?
Field of view is how much a lens includes from side to side, up and down. A short focal length lens has a very wide field of view. A long lens has a very narrow field of view. Depth of field is how much of your image is sharp moving front to back (depth). A wide (short) lens inherrantly has a lot of depth of field whilst a long focal length lens has very little. And last but by no means least is perspective. This is the way the magnification of different length lenses makes things 'stack up' in the picture.
I could ramble for ages about this - just watch the video and go practise. For more about focal length and how to exploit it take a look at 'Focal Length Explained' on our site http://www.photographycourses.biz/foc...
