"I'm here to talk about different film formats, essentially what size or how big or how little a piece of film is. In my hands is an uncut roll of 35mm film. A lot of exposures on a roll, 36, light, easy to carry around, you know excellent film for traveling, just one of the most popular films out there is 35mm format film. And you would use that basically just for ease, nice film. This size film is medium format film, this film tends to give you a much sharper image. The cameras that take these films can sometimes be a little bit more expensive but you can make a huge enlargement and make it absolutely tack sharp. And keeping with that in mind, this is a four by five negative, you could blow up this negative to the size of a wall and still keep your image absolutely tack sharp and beautiful and this is a great example of why people still use black and white film."
