Colour Management



 Colour Management 


Managing colour from the moment you use your camera requires your camera to be set in different formats. My camera is set purely to Raw. This gives me the widest range available in accordance to colour ranges but also requires myself to edit the flat image completely. Using Raw has no profile attached. I personally have never looked into using other colour ranges as I find this the most simplest and I have full control over the images I capture.

Colour Space

This is the most common colour space used on a DSLR camera but does not capture what the eye can see limiting the colour range and limiting colour especially greens from images. This is used in most TVs and screen equipment so there is no need to use other colour formats available but gives less control to the photographer regarding range.

Adobe RGB

This gives a wider range of colour space compared to common colour space and is widely used for images that require more use of colour ie. landscape images. This gives a more varied range of greens especially and blues and shows more of what the eye can see. 

Raw

As stated above raw has no profile attached and required editing in order to give full range to your images. Raw in comparison to j.peg however gives partially edited images and automatically changes colour variance ect complimentary to your camera settings on manual. JPEG is more widely used for speed for camera crew, news reported etc as these images can be used instantly due to the automatic editing. 





Embedded colour profile information is the information which is embedded in the images metadata with all the other information such as what type of camera took the image, Key words to describe the image, date and time etc. as shown below. 



Whenever editing images in an editing program, you are doing so using a specific working colour space. To ensure that you are preserving the colour you need to embed the profile before saving/ editing the image. Therefore this gives different programs the ‘code’ to interpret the colour intended. Getting into the habit of saving these profiles before print or to ensure that the colour doesn’t change.


Post Production

Monitor colour calibration ensures that the images you apply to any image editor is completely accurate. It also ensures that the image looks as good on social media/ internet and all other monitors. This gives peace of mind that the image you see on your screen will be the same or similar to what other view on their own screen and looks exactly how they should be.


I personally use SRGB for editing from RAW purely because I was not aware I could change the colour space. Upon learning of the outcomes of the different colour options I think I shall now choose to use Adobe RGB which I believe comes up on photoshop as a default. When opening up on Lightroom it is set up as a default as ProPhoto RGB. This would give a much more vast colour range particularly which my landscape shots. This is purely because I do like to print my images and I am also producing images to customers that I have taken for them also for printing. This will ensure the truest colour range in these prints. When uploading online I will probably be giving myself more work by changing this back to SRGB but this will all fall into my working pattern by keeping my edited truest files saved prior and making another copy in output SRGB.



JPEG

When opening up a JPEG onto photoshop it would automatically default onto SRGB unless changed otherwise. Setting up to Adobe RGB is the best choice in my view if shooting in JPEG as this will export from Lightroom or Photoshop for the internet in sRGB.

Raw vs JPEG





Most modern digital cameras shoot and save images as JPEG or RAW files. Both have their own advantages and disadvantages, but we should use the most appropriate format for our needs.


Differences between Raw & JPEG 

  • File size- Raw files are significantly bigger
  • Raw image contains all information uncompressed
  • Raw image all original detail
  • Raw gives complete control
  • JPEG files compressed 
  • JPEG is a Semi processed image
  • More JPEG files can be stored than Raw
  • Raw files are higher quality/ wider Dynamic range 
  • Raw gives better colour editing

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

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 https://photographylife.com/what-is-a-mirrorless-camera 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.
