What is ISO in DSLR Camera

What is ISO?
ISO - International organization for standardization.
In simple words, ISO can be said as the sensitivity of the sensor to the light. More is the ISO, more is the camera sensitive to light which means when there is less light (or night time) increase the ISO. In general, it ranges from ISO 100 to ISO 1600/3200/6400.

One major disadvantage is that the noise (grains) increases as we increase the ISO beyond certain limit..

How camera works?

To know this, lets look at all the parts that a camera has in it. Following figure briefly shows how light passes through different parts of camera. It is an SLR camera which is the most common and traditional equipment used in photography. Image credits Black Pearl The light reflected from a object passes through a set of lenses, and onto a hinged mirror. From there it is reflected to a five sided prism called Pentaprism in such a way that what ever you see through the eye piece is exactly the same light falling onto film. The click button flips the mirror. While looking through the eye piece, the mirror is in inclined position(as shown) and as soon as one presses the click button the mirror just moves upwards so that all light falls on film and therefore the image is captured.

What is photography

Photography is an art of capturing moments in a frame. An object is seen when light falls on it and is reflected back to our eye, everything that can be seen in this world is only because of light. So in order to take a picture of an object, one has to capture light reflected from that object. When we talk about photography, we actually talk about light and different ways to capture it. A little knowledge about light and its properties is necessary to understand photography. Video credits Joe Edelman Importance of Lighting in Photography Light: It is a spectrum of electromagnetic waves. Human eye can observe only a part of the light whose frequency is between 400nm to 780nm(approx.). So in photography all the light we see fall into this frequency range. Things to remember: Light travels in straight lines. Intensity of light decreases by square of the distance. Following video explains how inverse square law applies to photography Video credits Gil

Which Camera to buy?

I classify cameras into three types: Point and shoot cameras Bridge Camera Professional Camera As the name says "point and shoot" camera is for those situations where one has to point the camera to the object and just click. Almost all the compact digital cameras fall into this category. They are designed and automated such a way that everything is done in one click. Suggested for everyone, even to those who want to be a professional photographer because it very compact, easy to handle and quick.            Pros: Automatic features, Portability, Compact and Quick.          Cons: Very few manual options                                                                            Bridge Camera: It is a bridge between full automatic and total manual camera. It carries all the technology from point and click camera and adds some more manual features to it making it more versatile and good starter kit for enthusiastic learners.They tend to have more zoom capability as
