How does a camera work:

Camera works on optical technology. Light is the source or photography and when light rays are focused on an object the object become visible, This visibility is captured by camera. The very first camera we can think of is the human eye. he human eye catches images through it shutters (eye lids) when open and focus the object on the retina creating an image.

Lense plays a prominent role in camera. Convex lense also called converging lense is used in cameras because they focuses all light rays to one point. Whereas a concave lense also named as diverging lense scatters light rays.Cameras are designed using this technique. The first camera took 8 hours to take a film because the lense captured lesser light. Today we take a film in milliseconds.

Light passes through objects. Lence grabs all right rays scattered around the object and redirect them to a single point, creating a sharp image.

The distance between the lense and the photo film or digital sensor must be accurate to get a sharp image. Photographer adjust the lense to the exact distance of the sensor while seeing though the aperture to get a sharp image.

How to choose a right camera:

With so many camera models around, it is difficult to choose the right camera. Ask yourself the following questions and the answer will lead you to correct decision.

  • Why do I need a camera? I need a camera because I love photography.
  • Are you a professional photographer? If the answer is “yes” buy a DSLR camera. These cameras have the flexibility of changing the lense. So that one need not buy different cameras for different purposes.

.In general choosing the camera is a personal choice, Budget place a prominent role. There are DSLR camera ranging from $500 to $1200, High end cameras come with different lense like wide angle, macro, or fish-eye. Point and shoot cameras range is $200 to $400. Mirrorless cameras price tag will range from $300 to $400 and goes to a range of $4000.

Advantage of mirrorless camera is they do not have shutters and they are less weigh to their other models like DSLR. For continuous photography mirrorless is the better choice.
