Tips on photography

Light Source: Always be aware of your light source and how it is acting on your main subject, as well as how it is acting on the scene as a whole.

Exposure: Expose your main subject correctly, even at the expense of other elements in the picture. This will require a knowledge of how exposure works in your particular camera.

Fill Flash. If your main subject is in shadow but set against a bright background (this is often the case with informal portraits), you can set the exposure for the subject, but this usually results in an unpleasant overexposure of the background. If you expose for the background, the subject will be underexposed. The solution is to override the automatic flash and set it to the “on” position. The flash will light up the shadow areas so that both subject and background are correctly exposed.

Haze: Haze will destroy your scenics, except at sunrise and sunset. When the sun is low, the light acts on the haze in a different, often dramatic, way. But when the sun is high, shoot scenics when there is little or no haze.

Protect Your Eyes: If your camera is an SLR, and you are using the viewfinder rather than the screen, keep in mind that it is dangerous to look at the sun through a zoom or telephoto lens. These lenses act like magnifying glasses and intensify the sun’s rays.

Computer Editing: The principles of photographic composition can also be applied to the computer editing of photographs, but there is no substitute for taking a good picture in the first place. The less editing required afterward, the better.

Photography/Digital Workflow

“Digital Workflow” is the process by which photographs are taken, downloaded, identified, edited, delivered, printed, backed up, and stored. This can consist of any number of software programs such as the computer operating systems connectivity functions, the software shipped with the camera from the manufacture such as Canon’s “Digital Photo Professional” to “Digital Darkrooms” like “Aperture” (Apple), Photoshop (Adobe), GIMP (open source) or “Lightroom” (Adobe). There are many other less common programs that perform both general photo editing and very specific editing tasks such as sharpening, adding filters, or enlargement. Digital workflows allow photographers to shoot in RAW, and process their pictures exactly as needed.

Photographic Composition

There are a few simple techniques that will improve the quality of your photographic compositions. 

Framing

Framing, in photography, means placing an additional object, or objects, in the foreground of the picture for aesthetic purposes. The object does not have to completely surround the main subject.

A foreground object provides a point of reference. It gives a sense of distance and comparative size. It can hide elements that detract from the main subject. It is aesthetically pleasing and gives a feeling of completeness to the picture.

“A tree, a doorway, a window, or even a gap in a fence positioned around the subject can create a frame within the picture’s frame.” (Joy of Photography)

Repetition & Reflection

Make use of the repetition of shapes, colors, lines, objects, etc. They are all around us, and just waiting to be utilized by the photographer who combines observation with creativity.

Repetition gives form and unity to a composition. It can emphasize a theme or a subject.

Reflections, such as in water or glass, are an effective form of repetition.

The repetition is not created by the photographer, but merely observed and captured in an effective way in the photograph.

Closing In

Close in on your subject to exclude unwanted elements.

This is especially important with portraits, both candid and formal, where the subject usually fills the frame and very little else is visible.

It can be accomplished by getting physically closer, using a telephoto lens, or adjusting your zoom lens.

It eliminates wasted space within the picture and focuses more attention on the subject.

It minimizes background distractions.

Even scenics, with their wider panoramic view, should be carefully composed so that only the desired elements are included in the frame. Wide expanses of plain blue sky, for example, should not take up half the picture frame but can be reduced to a narrow strip across the top of the picture.

Closing can be done after the fact by editing the picture on a computer (“cropping”). However, this is less desirable, as the picture will have to be enlarged after cropping to bring it back to its original size, and picture quality decreases in proportion to enlargement.

“Some subjects don’t like you close up, so you’ll have to catch them unawares.” (Tim Fitzharris)

Leading Lines

The photographer should be on the alert for leading lines. The most commonly take the form of converging lines.

Leading lines draw the eye into the picture.

They can be used to direct the eye to the main subject.

They give form, unity, and depth to a composition.

Rule of Thirds

As a general rule, it’s a good idea to locate your main subject about a third of the way in from one side or the other, or from the top or bottom, or both.

This placement is more aesthetically pleasing than simply placing the main subject in the center, which seems predictable and uninteresting.

Sometimes, a subject may be in the center, but the main center of attention on the subject is a third of the way in, such as the face in a portrait or the clock on the tower of Big Ben (above right).

The rule of thirds is a general guideline. There are exceptions to the rule, however. Different types of subject matter or the purposes of the photographer may require different positioning of the main subject.

Blur the Background

Emphasize your subject and minimize distracting elements by blurring the background and/or foreground. This is accomplished by using a large aperture setting. (This requires a camera that allows you to control the aperture size and/or shutter speed.)

The distance within the clear focus area is called the depth of field.

The depth of field at different settings is marked on better quality lenses.

To diminish the depth of field, the aperture size must be increased. However, the larger aperture size lets in more light, so to avoid overexposure, the shutter speed must also be increased. The faster shutter speed will let in less light and balance the effect of the increased aperture size on the amount of light that enters the camera.

The balance between shutter speed and aperture size can be used to either increase or decrease the depth of field.

Many cameras today have an aperture priority feature. When aperture priority is selected, you can manually set the aperture size and the camera automatically sets the correct shutter speed to go with it. If you have a shutter priority camera, you can increase the shutter speed manually, and the camera will increase the aperture size automatically. Check the readout to see what the aperture size will be, then check the lens markings to see what the corresponding depth of field will be. Some SLRs have a button you can push which lets you see in the viewfinder how a picture would look at a particular aperture setting.

This method can also be used in reverse for the purpose of having an extremely wide depth of field, which has everything from very near to very far in sharp focus. To accomplish this, use a smaller aperture. This will require a longer shutter speed to compensate for the light loss. If the shutter speed is too long, a tripod may be required. (If you don’t have a remote control, use a shutter release cable with the tripod.) A substitute for a tripod, though not as good, is to find a firm place upon which to steady your camera.

Small aperture: large depth of field. Large aperture: small depth of  field.

What is Photography?

Photography is the process of making photographs by exposing light over a controlled amount of time to a light-sensitive medium, such as a digital sensor or photographic film. This is done through a device known as a camera. Cameras are essentially light-proof boxes that house the light-sensitive material.

The word “photography” was created from Greek and the simplified meaning is more or less:  “representation by means of lines” or “drawing”, together meaning “drawing with light”.
