I just got a 35mm camera for school and Im not 100% sure how to work it. On the "nose" of the camera, there are numbers 3.4 - 22 PK...i know they have to do something with the darkness and lightness of the photo. Do you use 3.4 when you take are taking a picture of somethint dark to make it more light? Or the opposite?

Your question is'nt real clear but by the numbers mentioned it sounds like you are talking about what is called the Fstop and yes it has to do with the amount of light but can also change the way your pictures appear by making background objects look either closer or farther from the main subject! it can also be handy for stop action pictures like say of a passing race car since the cars speed will blur its image in the picture if you use a slow shutter speed, you can sharpen it up by using the fstop wide open or set to it's lowest number value letting in more light which will let you use a faster shutter speed. if the light is you main concern use you shutter speed to control it not the Fstop. but note that changing your Fstop will also change the required shutter speed for the existing light conditions there are 3 basic light factors you can control the shutter speed the Fstop and the film speed only when all 3 are adjusted properly you will get a good picture! hopefully your camera has a built in light meter which is setup using all 3 factors and will take most the work out of figuring it all out!

That is commonly called f stops..it opens that aperture to the amount of light needed to make the type photo that you are wanting to make.Apparently you got a manual type camera..If you go to the web site that sold that camera or just put the name and model in the search engine with parenthesis around it.There will proabably be a million sites that can give you a manual on how to use the camera or at least someone that has the basics up to tell you what things mean..

Go to an online used book store or Yahoo! auctions and pick up a copy of Ansel Adam's "The Camera".
The numbers you are talking about are for the aperture. The small numbers mean a bigger opening....the larger numbers mean a smaller opening.

Those are the camera's f/stops. They control the speed of the shutter which determines how much light the film gets exposed to. Here's a link to better explanations of the f/stops: http://www.uscoles.com/fstop.htm
