Photography; Photography is a masterpiece that captures life, on a paper. Photography back in the day used to be really expensive because they had to use huge cameras to create photos. Photos used to be created with gelatin, silver, paint, etc. Photos got cheaper because they would take a actual photo, they add warm gelatin, and a piece of paper and smash it together. This creates a duplicate of the actual photo, but its not considered a photo after its print is on the paper. The technology for photos kept getting better, until it was quite cheap to make. Today, we use digital devices to capture digital photos, that have color, before there was no color but gray and black. and the photos can be deleted forever, unlike when paper was used. Technology has improved a lot, and it makes things easier for us.
