depth of field on an old school camera?!?
hey okay so i need to take pictures for my photography class at school for depth of field. like i need to take a picture of something in the foreground being razor sharp, then the back ground being out of focus or vise-versa..
how on earth do i do this?! lmao i have an old school canon ftb [we have to develop our own film for this class]. i know it has something to do with the f-stop but what numbers exactly should i put it on? i just need step by step instructions! pleeeeaseee and thank youu! =]]
btw, this is a picture of the camera i am usingg..

wait but like.. can you explain to me exactly where the f-stop is and how to change it. also the aperture? like i am clueless!!!
The terms "f-stop" and "aperture" are interchangeable - two ways of saying the same thing. The aperture is an opening formed by the movable blades of the diaphragm inside the lens. If you look at the lens you'll see a movable band with the numbers 1.8, 2.8, 4, 5.6, etc. on it. This is what you turn to change the f-stop. At f1.8 your lens is said to be "wide open" and will admit all available light. At f-22 your lens is "stopped down all the way" and admits very little light.
Depth of Field (DOF) is a function of three variables:
1) Lens focal length
2) The aperture chosen
3) Subject distance
At http://www.dofmaster.com/dofjs.html you'll find an explanation of DOF and a handy DOF Calculator which you can use to compute DOF for any combination of focal length, subject distance and f-stop imaginable.
Here are four examples using your camera and lens:
50mm @ f1.8 focused to 10'-0'' DOF is from 9'-5'' to 10'-9''
This means that anything from 0'-7'' in front of your subject to 0'-9'' behind it will be in focus.
50mm @ f22 focused to 10'-0'' DOF is from 5'-6'' to 53'-10''
This means that anything from 4'-6'' in front of your subject to 43'-10'' behind it will be in focus.
50mm @ f1.8 focused to 5'-0'' DOF is from 4'-10'' to 5'-2''
This means that anything from 0'-2'' in front of your subject to 0'-2'' behind it will be in focus.
50mm @ f22 focused to 5'-0'' DOF is from 3'-7'' to 8'-4''
This means that anything from 1'-5'' in front of your subject to 3'-4'' behind it will be in focus.
Read the explanation of DOF at the site I linked and play around with the DOF Calculator.
I hope your photography teacher just had an off-day when he/she discussed DOF in class.
