Photography involves capturing images using light or electronically with a camera. A lens focuses light onto light-sensitive material inside the camera, producing an image. The result is either a negative or positive image. Photography is used in various fields like science, manufacturing, art and communication. Wildlife photography involves capturing animals, plants and insects in their natural habitat, which can be challenging. Landscape photography shows vast natural or man-made areas like mountains or cities. Macro photography involves taking extremely close-up photos of very small subjects like insects at larger than life size.

2. Photography is the science, art and practice of creating images by recording
an object either with light or electronically with a camera’s image sensor, or
chemically with a material that is sensitive to light such as photographic
film.
A lens is usually used to focus the light reflected or produced by objects into
a real image on the light-sensitive surface inside the camera. This produces
an electrical charge at each pixel with an electronic image sensor, which is
electronically processed and then stored in a digital image file for
display/processing later on. The result of photographic emulsion is an
invisible latent image, which is later chemically "developed" into a visible
image, either negative or positive depending on the photographic material
and the method of processing. A negative image is traditionally used to
photographically create a positive image on a paper base (known as a print)
either by using an enlarger or by contact printing.
Photography is carried out in many fields of science, manufacturing (e.g.
photolithography) and business, as well as its more direct uses for art,
recreational purposes, and mass communication.

3. Wildlife photography is a genre of photography that involves
capturing various forms of wildlife (animals, plants, insects, etc.) in
their natural habitat. It is one of the more challenging types of
photography. Wildlife photographers that focus on animals usually
need good field craft skills; some animals are difficult to approach
and therefore the photography must have a knowledge of the
animal's behaviour in order to be able to predict its actions.
Wildlife photographs can often be taken using basic cameras and
equipment, some certain types of wildlife require specialist
equipment, e.g. macro lenses for insects, long focal length lenses for
birds and underwater cameras for marine life. However, a great
wildlife photograph can also be the result of being in the right place
at the right time. In the early days of photography, it was difficult to
get a photograph of wildlife due to slow lenses and the low
sensitivity of photographic media.

numerous awards.
Jess Findlay – A 20-year old
photographer from BritishColumbia
whose love for nature originated from
birdwatching and exploring.
Joel Sartore - A photographer who has been
fascinated with nature since he was a child.
For twenty years, he’s been a contributor to
National Geographic
Suzi Eszterhas - A California-based wildlife
photographer who works primarily in
Africa. She’s been featured in several
major publications, including the BBC.

5. Landscape photography shows an area within the world,
usually vast and unending, but sometimes tiny and
microscopic. Landscape photographs typically capture
the presence of nature but can also focus on man-made
features such as a large city.
Many landscape photographs show little or no human
activity and are created in the pursuit of a pure,
untouched vision of nature that is free of human
influence, instead featuring subjects such as mountains,
strong weather, and ambient light. Like most forms of art,
the definition of a landscape photograph is broad, and
may include manmade features like urban settings and
industrial areas, as well as nature photography.

7. Macro photography (also known as photomacrography, macrography, or
macrophotography), is extreme close-up photography, usually of very small
subjects such as insects, in which the size of the object in the photograph is
larger than its life size. By some definitions, a macro photograph is a photo in
which the size of the subject on the negative/image sensor is life sized or greater.
However, in other uses, it refers to a finished photograph of a subject at larger
than life size.
Macro lenses of different focal lengths find different uses:
• Continuously-variable focal length – suitable for virtually all macro subjects
• 45–65 mm – product photography, small objects that can be approached
closely without causing undesirable influence, and scenes requiring natural
background perspective
• 90–105 mm – insects, flowers, and small objects from a comfortable distance
• 150–200 mm – insects and other small animals where additional working
distance is required
