After you have input your settings, your light meter will indicate what adjustments you will need to make before taking your shot. The light meter is a tool used to gauge your manual settings.
It also indicates that your image should be well-balanced. If your light meter reads negative, it means the image will be underexposed, or too dark.
A light meter that reads positive will mean the image will be overexposed, or too light. You can adjust the different settings on your camera to pull the meter to zero. When you are ready to shoot in manual mode, here is one way to go through your settings.
Choose the ISO that would best work for your lighting conditions. If you are in a darker space or indoors, choose a higher ISO. Second, decide if depth of field or motion is more important.
If you choose depth of field, you will need to adjust your aperture before you compensate with the appropriate shutter speed; vice versa for motion. Make slight adjustments based on the results. There are a couple of tricks to use when trying to find the right balance for an image. For a medium level of ISO sensitivity, the shutter speed and aperture can be in the middle also.
However, if you use a high ISO sensitivity, a faster shutter speed means you should make your aperture larger low f-stop and a slow shutter speed means you should make your aperture smaller high f-stop.
The best way to learn more about your manual settings is to try different combinations. Keep a log of the results so you can track which settings worked the best for different scenarios.

November 11, features. DSLRs use a digital mechanism that processes the received data and records it using the camera sensor, whilst SLRs record information about every image on a separate exposure of the film.
The typical film size is 36x24mm. This is why the modern professional DSLRs are sometimes called 35mm cameras or full-frame cameras.
We already talked about how digital single lens reflex cameras function. However, the layout of the most essential settings—aperture, ISO, and shutter speed—as well as the ergonomics may become a stumbling point. Since the SLR camera lacks an electronic system, these settings are adjusted mechanically either on the body of the camera or the lens.
For example, in most SLR cameras the aperture should be set manually using the aperture ring on the lens. You will notice changes in lighting straight away by looking through the viewfinder. The most important element in the camera is the film compartment, located on the back of the camera, that is divided in several interconnected elements.
You can open the film compartment using a button located either on the side of the camera or on its back. There are two types of consumer film cameras on the market -- SLR cameras and " point-and-shoot " cameras. The main difference is how the photographer sees the scene. In a point-and-shoot camera, the viewfinder is a simple window through the body of the camera. You don't see the real image formed by the camera lens, but you get a rough idea of what is in view.
In an SLR camera, you see the actual real image that the film will see. If you take the lens off of an SLR camera and look inside, you'll see how this works. The camera has a slanted mirror positioned between the shutter and the lens, with a piece of translucent glass and a prism positioned above it. This configuration works like a periscope -- the real image bounces off the lower mirror on to the translucent glass, which serves as a projection screen. The prism's job is to flip the image on the screen, so it appears right side up again, and redirect it on to the viewfinder window.
When you click the shutter button, the camera quickly switches the mirror out of the way, so the image is directed at the exposed film. The mirror is connected to the shutter timer system, so it stays open as long as the shutter is open. This is why the viewfinder is suddenly blacked out when you take a picture.
In this sort of camera, the mirror and the translucent screen are set up so they present the real image exactly as it will appear on the film. The advantage of this design is that you can adjust the focus and compose the scene so you get exactly the picture you want. For this reason, professional photographers typically use SLR cameras. These days, most SLR cameras are built with both manual and automatic controls, and most point-and-shoot cameras are fully automatic.
Conceptually, automatic cameras are pretty much the same as fully manual models, but everything is controlled by a central microprocessor instead of the user. The central microprocessor receives information from the autofocus system and the light meter.
Then it activates several small motors, which adjust the lens and open and close the aperture. In modern cameras, this a pretty advanced computer system. In the next section, we'll look at the other end of the spectrum -- a camera design with no complex machinery, no lens and barely any moving parts. As we've seen in this article, even the most basic, completely manual SLR is a complex, intricate machine. But cameras are not inherently complex -- in fact, the basic elements are so simple you can make one yourself with only a few inexpensive supplies.
The simplest sort of homemade camera doesn't use a lens to create a real image -- it gathers light with a tiny hole. These pinhole cameras are easy to make and a lot of fun to use -- the only hard part is that you have to develop the film yourself.
A pinhole camera is simply a box with a tiny hole in one side and some film or photographic paper on the opposite size. If the box is otherwise "light-tight," the light coming through the pinhole will form a real image on the film. The scientific principle behind this is very simple. If you were to shine a flashlight in a dark room, through a tiny hole in a wide piece of cardboard, the light would form a dot on the opposite wall.
If you moved the flashlight, the light dot would also move -- light beams from the flashlight move through the hole in a straight line. In a larger visual scene, every particular visible point acts like this flashlight.
Light reflects off each point of an object and travels out in all directions. A small pinhole lets in a narrow beam from each point in a scene. The beams travel in a straight line, so light beams from the bottom of the scene hit the top of the piece of film, and vice-versa. In this way, an upside down image of the scene forms on the opposite side of the box. Since the hole is so small, you need a fairly long exposure time to let enough light in. There are a number of ways to build this sort of camera -- some enthusiasts have even used old refrigerators and cars as light-tight boxes.
One of the most popular designs uses an ordinary cylinder oatmeal box, coffee can, or similar container. Its easiest to use a cardboard container with a removable plastic lid.
Choosing a good camera design, film type and exposure time is largely a matter of trial and error. But, as any pinhole enthusiast will tell you, this experimentation is the most interesting thing about making your own camera. To find out more about pinhole photography and see some great camera designs, check out some of the sites listed on the next page. But amazingly, all these designs -- from the simplest homemade box camera to the newest digital camera -- combine the same basic elements: a lens system to create the real image, a light-sensitive sensor to record the real image, and a mechanical system to control how the real image is exposed to the sensor.
And when you get down to it, that's all there is to photography! For more information on cameras, light, film and related topics, check out the links on the next page.

Homemade Cameras As we've seen in this article, even the most basic, completely manual SLR is a complex, intricate machine. The first thing to do is paint the lid black, inside and out. This helps light-proof the box. Be sure to use flat black paint , rather than glossy paint that will reflect more light. Cut a small hole about the size of a matchbox in the center of the canister bottom the nonremovable side. Cut out a piece of heavy-duty aluminum foil , or heavy black paper, about twice the size of the hole in the bottom of the canister.
Take a No. You should only insert the needle halfway, or the hole will be too big. For best results, position the foil between two index cards and rotate the needle as you push it through. Tape the foil over the hole in the bottom of the canister , so the pinhole is centered. Attach the foil securely, with black tape , so light only shines through the pinhole.
All you need for the shutter is a piece of heavy black paper large enough to cover most of the cannister bottom. Tape one side of the paper securely to the side of the cannister bottom , so it makes a flap over the pinhole in the middle.
