Nice photo's Jack. You sure know your stuff
It looks like my trip to Vancouver might be bumped ahead 1 week, since I'll be attending a writers course in Fernie the weekend I was planning on heading that way
Originally posted by Gaelen I have no idea what DOF is....I'm a little new to this, i have used p & s cameras years
DOF is Depth of Field basically meaning the amount of the picture that's in focus.
This to a large extent is effected by the aperture or F-stop, and how close to the object that you are.
You'll learn more about it over time, but basically say that if you laid a series of pop bottles out along a sidewalk all 3" further away from you, set your camera onto AV, then turn the dial to the smallest number possible (4.5 on the lens presently on my camera)then look through the view finder you'll discover that you can focus in on 1 bottle.
Then turn the dial making that number bigger and bigger and you'll see that you can have 2 or more bottle focused relatively close.
It's something fun to try on your own and will teach you a lot about your camera.
They don't have to be bottles, use your imagination.
You can use this effect to make an artistic photo.
I will point out that every lens is different when using this technique, but they all have a similar effect.
The problem with lowering the F-stop to take this sort of picture is it also speeds up your camera, so any motion blur will be reduced.
So what I would have done with that photo is taken it at a higher F-stop setting (to slow the camera down) to increase the motion blur of his hand, but done some post processing to blur the background
I hope that this helps you a little.
