lens nodal points and perpendicular to the image plane intersects the image plane at the principal point. The distance measured from the rear nodal point to the nega-tive principal point or from the front nodal point to the positive principal point is equal to the focal length f of the camera lens. 10-5.

Let’s start with the word photography itself, which has an interesting background. The word “photo” comes from the Greek word meaning light, and the word “graph” is derived from the Greek word meaning drawing. So photography is essentially drawing with light. The process involves capturing light with a physical medium such as film, or through elect...
Most of the time your goal is to capture an image that is properly exposed – that is, not too bright and not too dark. However, there are times when you might want to intentionally make a few different images of the same scene; one that is too dark, one that is too bright, and one that is, as Goldilocks might say, just right. AEB or Bracketing is o...
The aperture is the opening in your camera lens. The bigger your aperture the less light you need in order to take a picture or the less time your shutter will need to stay open in order to collect enough light for the picture. Think of two buckets sitting in the rain, each with a base 10cm in diameter. One also has a 10cm opening on top, while the...
Put your camera in Aperture Priority Mode (on Nikon cameras, turn the top dial to A, on Canons and others turn it to Av) and you can then set your desired aperture while your camera figures out the shutter speed and ISO required to have a properly exposed picture. Note: the camera will only choose the ISO for you if you are using Auto-ISO. If you d...
Autofocus points are all the tiny little dots or squares you see when you look through the viewfinder. Some cameras have a lot, some don’t have very many, but for practical purposes, the quantity doesn’t matter. If you are comparing cameras and one has 29 AF points while another has 99 AF points, both are perfectly capable of taking great pictures,...
On most cameras, you press the shutter button down halfway to make it focus on your subject. But instead of doing this you can also set your camera to use a button on the rear of the camera, that you press with your thumb. It sounds a little counterintuitive and feels funny at first, but it’s a nice way to give yourself more control over your photo...
Bokeh is a fancy name for the blurry, out-of-focus, areas of a picture. For maximum bokeh use a wide aperture, get very close to your subject, and ensure the subject is far away from the background.
This is a setting on your camera used for really long exposures. When in BULB Mode, your camera will open the shutter when the shutter button is pressed and then closes it when the button is released. If you’re going to use this mode, it also helps to have some type of remote or cable release attached to your camera so it doesn’t pick up vibrations...
Burning means to selectively make parts of a photo darker. The name comes from techniques used on photographic negatives in the days of printing in a darkroom, but now it’s usually just done in Photoshop, Lightroom, or another image processing program. For more on burning (and dodging) read: What Are Burning And Dodging And How They Can Help Your P...
Chimping is checking your photos on the rear LCD screen of your camera constantly, often for no particular reason. It’s not a bad habit per se, but if you learn to stop doing this you will probably start to trust your instincts more and pay more attention to what’s in front of your camera rather than what’s on the screen. Try disabling the auto-rev...

S A type of photographic print, invented in 1850 by Frenchman Louis Désiré Blanquart-Evrard (1802-1872). It consists of a sheet of paper coated in egg white (albumen) and salt, then dipped in a light-sensitive silver nitrate solution. The paper, when dried, is overlaid with a glass negative and exposed to the sun.

Oct 26, 2023 · Viewpoint refers to the position or angle from which a photograph is taken. It's the relationship between the camera and the subject. Think of it as the seat you choose in a theater. Sit in the front, and you're immersed in the action; sit at the back, and you get the bigger picture. Similarly, your choice of viewpoint in photography can change ...
