Formats

Theory


In photography the light, film and sensor size all determine image formate ie logo sensitive. It is important to make an exact copy of what we are photographing as the sensor effects the quality. there are a variety of different formats available and these are as follows. This helps us understand about light and how it is used to make images.

The Pentaprism

A pentaprism is a five sided reflective prism used to deviate light by a constant 90 degrees, the light reflects inside the prism allowing transmutation of an image through a rift angle without inverting it.


Small Format (DSLR SLR Mirrorless)


Advantages 

  • Portable
  • Modular
  • Image is viewable right away
  • intuitive use
  • choices for file size
  • more accesable settings
  • more storage

Disadvantages

  • not 100% quality
  • enlarging the image won't work well

Medium Format (Full frame DSLR Film)

Advantages

  • Better Quality than small format
  • Still relatively portable
  • choice of location
  • images can be viewed right away depending on camera used
  • wider field of view

Disadvantages

  • less choice of storage
  • more expensive
  • can be bulky or heavy

Large Format



Advantages

  • good quality images
  • image size and enlargement possible

Disadvantages

  • not portable
  • limited location
  • large equipment
  • everything must be manual
  • expensive


Large Format camera movements

Large format camera movements allow you to be able to make images that wouldn't normally be possible with a fixed camera.  These are most commonly found in cameras that hold 4x5 inch films.

  • Linhof
  • Wista
  • Acra swiss
  • Sinar

Most large format cameras have movable front and rear standards. The camera lens is attached to the front standard and the ground glass is where the rear standard is found. This is called monorail design. These cameras sit along a single rail to which it attaches. For rise and fall movements this is located at the front of the camera, from its central position the lens can be moved up or down.

My dark Room Images

Dark Room Below I have shown examples of how I have started creating my darkroom images using a film camera up until completion.  Equipment used developing from Resin & Fibre based paper Enlarger for resin start from grade 3 Filter paper work from grade 2 Firstly it is best to create a contact sheet, this will allow us to see what exposure time is best used. From the film strip, place images in glass responder and use focus to create sharpness. Once the correct focus is created I used a piece of black card to cover approx 3 -4 inches of the image projection in order to see what best exposure was required. A piece of light sensitive paper is then placed in position and exposure time then begins. Each exposure time was then limited to 5 seconds each. From that I could guesstimate what my required exposure time would be. thus was repeated x3 for each Image. Differences between paper types are:- Resin paper is generally thinner than fibre. It usually weights around 190gsm. The paper is

Fine Art Photography Images This collective is what I want to achieve using my own view. I want to achieve a mood story in relation to people with an impulsive output but relating to surjects that affect people in todays culture. This would involve creating eye catching, controversial images taken from unusual angles with moody backgrounds and in unnatural poses. Below is a collection of images that reprise my vision of notion using people and portraiture and emotion. Pandemic Created using window lighting technique using Canon 2000d, 18-300mm lens, 1/20-f5-100.   My sitter is facing toward the window light in the centre of the image giving the face and the mask the main focus with the background darkened.  How I progressed this image is illustrated below. My thought process for this image was to create an image that portrays how a lot of people felt towards the end of isolation during the pandemic. Not only wearing one face mask but wearing six, covering the entire face. I feel like t
