INTRODUCTION TO ADOBE PHOTOSHOP CS3

INTRODUCTION.

Today's lesson we heve been introduced to photoshop. For beginner, we will be using Adobe photoshop CS3. We also has been introduced to some of the tools in photoshop. Here, i found a video about the tools in photoshop. Check it out...

DEPTH OF FIELD (D.O.F)

Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. A preferred selection Depth of field ("DOF") in a focused subject in an image can be quite subjective.

f/5.6, 1/40 sec, ISO = 800

Three factors can affect the depth of field:

I. focal length of the lens

II. distance from the camera to the subject

III. the size of the aperture or the setting of the f-stop

I. Focal Length Of The Lens

The depth of field is inversely proportional to the focal length of the lens; that is, the smaller the focal length number of the lens, the greater the depth of field. For example, a 28mm lens has the ability to capture more of the picture in sharp focus than a 100mm lens.

II. Distance from the camera to the subject

Depth of field is directly proportional to distance; i.e. a subject at a greater distance will have greater depth of field than a close-up subject. Therefore, you need not worry as much about a distant subject being out of focus.

III. The size of the aperture or (f-stop)

While changing the aperture (f-stop) will not have a striking effect on the depth of field for a distant subject or a wide angle (short focal length) lens, it can make a great deal of difference in a close-up or a photo taken using a telephoto or zoom lens.

A wider aperture (smaller f-stop number) will result in a shallower depth of field. You can use this to keep either the foreground or background out of focus while maintaining the subject in focus. When changing the aperture setting, you will need to also adjust the shutter to maintain the correct exposure.

Aperture = F5.6
Shutter = 1/1000

Little/Shallow depth of field

Aperture = F22
Shutter = 1/60

Greater/More depth of field

CLASS ACTIVITY: COMPOSITION GUIDELINES

COMPOSITION IN PHOTOGRAPHY

• Good Composition is a key element of good photographs yet is something that is hard to define.

Good Composition Guidelines in Photography:

1. Simplicity

• Look for ways to give the center of interest in your pictures the most visual attention.
• One way is to select uncomplicated backgrounds that will not steal attention from your subjects.

f/5.6, 1/320 sec, ISO = 200

f/5, 1/500 sec, ISO = 400

2. The Rule of Thirds

• The rule states that an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections.

f/36, 1/125 sec, ISO = 400

f/5, 1/4000 sec, ISO = 400

3. Lines

• You can use diagonals as leading lines to provide a way into the picture. It's a simple and easy path for the eye to follow to the main subject. You can also use repetitive lines to draw viewers' attention to your center of interest. One of the most common and graceful lines used in composition is called the S curve.

f/5.6, 1/1000 sec, ISO = 200

4. Balance

• Good balance is simply the arrangement of shapes, colors, or areas of light and dark that complement one another so that the photograph looks well-balanced.

f/11, 1/640 sec, ISO = 200

5. Framing

• Sometimes you've a object of huge dominance within a scene.
• While breathtaking on-location, the final picture looks often much less impressive due to uninteresting space around the object.
• Try to find a frame which can eliminate the unimportant surrounding and focus the view.

A frame serves numerous purposes:

• It gives the image depth and helps to give the perception to viewers of it that they’re looking at something that is more than 2 dimensions.
• Framing can add context to a shot.

LIGHTING STUDIO

Today, we had learned about studio photography. Today’s lesson is just to know how to construct studio photography. We were introduced about equipments, techniques and so on.

LIGHT METER

A light meter is a device used to measure the amount of light. In photography , a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include a computer, either digital or analog , which allows the photographer to determine which shutter speed and f-number should be selected for an optimum exposure, given a certain lighting situation and film speed .

Light meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. They are used in the general field of lighting, where they can help to reduce the amount of waste light used in the home, light pollution outdoors, and plant growing to ensure proper light levels.

UMBRELLA

Photographic umbrellas are constructed similar to a rain umbrella, but made with materials that control light. Most umbrellas are black on the outside with a reflective surface inside. Lighting units are mounted such that they are pointing into the umbrella. When triggered, the light bounces around inside of the umbrella then out toward the subject providing non-directional lighting. The lighting from a photographic umbrella is typically smooth and soft.

Umbrellas are quite common do to their low cost and great results. Many portrait photographers favor umbrellas to soft boxes because of the round catch light, or reflection they produce in the subjects eyes.

Umbrellas have been manufactured in many variations of size and color. Some are even designed to be convertible, having their black backing removed, which allows the light to pass through the inner layer of diffusion material. These umbrellas provide great flexibility and creative options.
