Photography has evolved over the years ever since the first picture was taken way back in 1886. Back in the day, photos were taken for a specific purpose thus making it a custom shot depending on the occasion. However, today, with more and more images being used for representational purposes in the media, customs shots are being replaced by stock shots. Stock photos essentially refer to a collection of images which have already been taken by professional photographers keeping in mind the brief given by their clients. The use of stock photos was more economical than a flying to a particular destination to get the desired shot. For example, if you wanted a picture of a beautiful beach somewhere in a tropical paradise, flying out there just to take a few pictures will make no sense at all. Instead, local photographers, there can take pictures depending on the brief you give them, and upload the same via the internet which will not only save you time but a lot of money as well. This concept evolved the development of dedicated websites to find and purchase stock photographs. These websites and agencies made it very easy for professional photographers to market their pictures and for designers and media houses to buy the images compiled by these sources.
