Nikon cameras have lots of fans between both amateur and professional photographers. The brand provides such a huge variety of models and accessories, that it makes it really easy for you to start taking quality pictures, irrespective of the experience or training you have in the field of photography. However, as soon as you download the first set of photos made with your brand new Nikon D800, for example, you might notice they come in a format that your PC can’t decide how to open. The NEF image format is not supported by most regular viewers, and you might also notice it uses a lot of space on your hard-drive.
