BASIC'S OF PHOTOGRAPHY
1. What is Photography? Photography is the science, art and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.

3. What is a DSLR camera?
Ans: DSLR stands for “Digital Single Lens Reflex”. In simple language, DSLR is a digital camera that uses mirrors to direct light from the lens to the viewfinder, which is a hole on the back of the camera that you look through to see what you are taking a picture of.
4. What is ISO?
Ans: ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important (and most expensive) part of a camera and it is responsible for gathering light and transforming it into an image. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. But higher sensitivity comes at an expense – it adds grain or “noise” to the pictures.
The difference is clear – the image on the right hand side at ISO 3200 has a lot more noise in it, than the one on the left at ISO 200.
A. When to use low ISO
Always try to stick to the lowest ISO (base ISO) of your camera, which is typically ISO 100 or 200, whenever possible. When there is plenty of light, you should always use the lowest ISO, to retain the most detail and to have the highest image quality. (Outdoor, Sunny days)
B. When to increase ISO
You should increase the ISO when there is not enough light for the camera to be able to quickly capture an image. Other cases where you might want to increase ISO are when you need to get ultra-fast shots. But before increasing the ISO, you should think if it is OK for you to introduce noise to the image. (Indoors, no flash zones, shade or low light shots)
The ISO setting on your camera is simply the film speed standard set by the International Organization of Standardization.
5. Aperture:
Aperture is basically a hole in your lens that allows light to travel through it and towards the camera sensor.
The smaller the Aperture F number (Focal Ratio), the faster your camera takes to shoot the image. This is due to a larger hole, allowing more light in to hit the camera sensor with each exposure.
The Larger the F number, the more time your camera takes to shoot the image. This is due to a smaller hole that allows less light in. If you take a photo and find the result is too dark, or camera is taking a long time to shoot them allow more light in by changing the Aperture to a lower F number.
6. Depth of Field:
Depth of field refers to the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance.
A. Shallow (Small) Depth of Field:
A shallow depth of field simply means that one specific area of your photo is sharp while other elements remain blurred. When the aperture is large (ex. f/1.8), the area in front and behind the focus point is very slim or shallow. That means that objects right in front and right behind the plane of focus is already going out of focus.
B. Deep (Large) Depth of Field:
When the aperture is small (ex. f/16), the image has a deep or large depth of field. This means that the focus range covers a large area front-to-back, from several yards in front of the focus plane to nearly infinity behind it. Entire photograph will be in focus.
7. Shutter Speed:
shutter speed or exposure time is the length of time a camera's shutter is open when taking a photograph. The faster your shutter opens and closes the less you have to worry about a blurry image. Shutter speed is measured in fractions of a second, for example 1/60th of a second. The smaller the fraction the faster the shutter speed. For example 1/500 is faster than 1/4.
To blur – create creative exposure – set slow shutter speed
To freeze – set faster shutter speed.
8. Panning:
Panning is when you deliberately move the camera in parallel and at the same speed as the subject. Recommended shutter speed from 1/60th of a second then adjust from there if needed. 1/60th to 1/8th is usually sufficient for most subjects.
