An example of depth of field
In another post about aperture priority, I talked about depth of field as being the amount of the photo that is in focus for a given aperture setting.
The following two images demonstrate this. The first uses an aperture of f2.8 which is a very wide aperture meaning the hole that light can pass through is large. This gives a narrow depth of field with only a small area of the image in focus.
The next image shows the other extreme, a very small aperture, f22. This has much more of the image in focus, but requires a longer shutter speed.
Try the different aperture settings on your camera and learn how changing the aperture will effect the image.
[...] Depth of field is also going to be more obvious. Being that close up you will need to use a small aperture to make sure you get a suitably large area in focus, although you can also use aperture creatively to pick out one area. [...]
This is an excellent example, coupled with the short article explaining aperture priority mode it has really helped me understand things better. Thanks !
oh, and I’m also curious as to what the wing is from ?
Hi Frank, glad you found it useful. The wing, I think, is from a … well, it’s not a harrier, but the one that’s very similar to a harrier, or maybe came before the harrier that looks exactly the same. It’s sitting at Brooklands museum.
They are called vortex generators, nice and concise explanation using an excellent example. Thanks.
