Introduction To Photo Films

Today was our first introductory lesson to the Photo Films unit. We have Matt as our tutor for this unit and our first lesson was running through different types of photo films, what they’re used for, how they’re used in advertising and different screen ratios/file sizes. As I am very new to filming I took down as many notes as I could that I thought would be useful to me throughout this project unit.

First of all Matt went through different Digital Films, Out of House (OOH) types.

  • fashion films- beyond the glass, stoppable films
  • billboards
  • tube station moving posters- tell a story, take over the station
  • stock videos- photo libraries, GIFS, repetitive movements/on a loop
  • special FX 
  • film/documentary

After this, Matt proceeded to go through different equipment requirements with us, and explained which type of filming equipment would be best to use for different types of video/film.

  • Essential- DSLR with movie mode, CF or SD card, laptop
  • Optional- prime lenses, video tripod with fluid head, external sound recorder, gun mic/Lavalier mic, variable ND filters, continuous lights
  • Extra- handheld camera rig, loupe, follow-focus, dolly or slider, matte box & filters, boom mic, sound mixer

We got told about the different aspect ratio types and file sizes that film can come in with TV, cameras and smartphones/tablets.

  • Aspect Ratio- 
    2.35:1 / Cinemascope
    1.78:1 or 16:9 / Widescreen (all HD modes)
    4:3 / Standard (all SD modes)
    iPads close to 4:3, iPhones close to 14:9
  • DSLR Sensor Ratio (quite square)
    Roughly 7:5 (close to 4:3 ratio). Not all of a cameras sensor is utilised when shooting in 16:9 Movie mode.
  • Resolution at 16:9 HD- 1280px wide by 720px high
  • Full Hd at 1920px wide by 1080px high
  • Resolution at 16:9 4K- ULTRA HD
  • 4096px wide by 2160px high (4x larger)

The last thing we went through for the photo films introduction was the exposure triangle. The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph: aperture, shutter speed, and ISO. One must balance all three of these to achieve a desired result, an adjustment of one requiring adjustments of at least one of the others.
