Photography

1) Different types of photography:

1) Cityscape Photography
2) Commercial Photography
3)Concert Photography
4)Digital Photography
5)Documentary Photography
6)Food Photography
7)Fashion Photography
8)Nature Photography
9) Night Photography
10)Wedding Photography


2) Equipments for photography

- 2 camera bodies
- Flash Card
- Laptop Computer
- Lenses
- Flash Unit
- Internet access

3) Aperture
Aperture of the lens is the diameter of the lens opening. It is controlled by an iris. The larger the aperture, more light will reach the image sensor/ film.


4) Focus
There are many methods of focusing, depending on the type of object being photographed. The eye of the object is the most important part of the thing to be captured.



5) Shutter Speed
It is the amount of time that the shutter is open.


6) ISO
Traditional photography(film): Indicates how sensitive film was to light. It was being measured using numbers. The lower the number, the lower the sensitivity the film. It causes you to take photos with finer grains.



7) Metering
Metering is something which involves the camera to take light level reading from the scene and selecting appropriate combination of shutter speed and apeture. This sets the required exposure value.

Centre-weighed: The whole of the scene first then central spot. The results are the average reading with extra weight given to the centre part. Some cameras allows the user to change the amount of weight given to the central area. About 60 - 80 % of the sensitivity is brought towards the centre part of the image. Making it great for portraits.

Spot Metering: Zone is an example of metering which takes readings from many different zones. The number of zones used can differ from one camera to another. This is useful for scenes with low contrast.

8) White Balance
It is removing unrealistic colour casts. The object that appears white in real life, will appear white in your photo. Camera white balance controls the "colour temperature" of a light source. It refers to the warmth or coolness of the white light. Eyes are very good at judging the colour white under different light sources. But, digital cameras often have many difficulties with auto white balance (AWB). A wrong WB can cause disgusting blue, orange and even green colour casts which are unrealistic and damages the beauty of the portraits. WB in olden photography(film) requires attaching a separate cast removing filter for each lighting condition. WB improves your photos under a wider range of lighting conditions.


9) Composition(Rules)

Pattern: Highlighting and emphasizing patterns makes the picture striking.

Symmetry: Strong composition and a good point of interest makes the picture striking.

Texture: It makes pictures come alive and become something like 3D.

Depth of Field: Isolates an object from the foreground or background, when using a shallow depth of field.

Lines: They draw the eyes to key focal points in the picture.



10) Techniques

There are a lot of techniques but I will only elaborate on some.

Sunlight - Natural sunlight provides one of the best lighting. But, too bright sunlight casts strong shadows. Overhead sunlight can remove some of the fine details on the face.

Flash - Your flash should be about 3 metres from the object you are taking. If too far, your photo will be dark. If too close, the bright light will delete the fine details.

Camera Positioning - The camera angle makes the shot more creative. Move the camera according to the object you are taking. Zoom in or out to change the composition.
