Taking a photograph has never been easier. We hold more computer power in our hands than the computers that were involved in the launch of the first spaceship to the moon. It is so easy to take a photograph on a phone. Now, phones have 1, 2 3 or 4 cameras for different purposes; Landscape, macro, zoom and the list goes on.
You may find it hard to believe, but there was a point in time when all the photos taken were not seen until they came into contact with various chemicals. These photos were not limited by Gigabytes, but physical strips of photosensitive material which was only a certain length, not size, length. Like centimetres. This physical photosensitive material is called FILM.
35mm film, known as 'full frame' uses light-sensitive crystals that when exposed to light, produce an image (usually negative) onto the material. It must not be exposed again to light before developing otherwise the image will be blank. The photo you have taken will not be seen till developed. Unlike digital media, you cannot see how the image looks.
Developing is the process of fixing the image onto the film which means it is no longer light sensitive. We will discuss developing in another article.
