COLOUR MANAGEMENT
The planning for a presentation to GCPS members on Colour Management looks to be nearing completion.
We will be holding a special extra meeting on Thursday 5th March at KOA to hear a presentation organised by Sanjoy Banerjee, Business Development Manager for “DES”of Melbourne and Sydney. “DES”are the distributors for the ColorMunki colour calibration equipment from X-Rite (incorporating Gretag Macbeth) who also make the “Huey” (and the Eye-One Display).
Sanjoy will be bringing with him a rep from Ted’s in Brisbane (Cameron Attree, (Master of Photography) and will be giving part of the presentation. The presentation with cover both the calibration of monitors and of printer/paper/ink combinations
Our interest in the “Colormunki” comes from the fact that it is a 3-in-one device that enables the calibration of Computer Monitors, Printers and Digital Projector displays.
We purchased one last year prior to our hosting of the 2008 InterClub Competition for Digital Images and now use it to calibrate our laptop and digital projector combination for consistent display of our digital images (or at least we try - as some people are not happy with our efforts).
Sanjoy claims that with a properly calibrated system one can produce good colour prints using quite modest printing equipment.
If you are like me and use a commercial printer to make your prints it is also essential to know which colour space is required for your images (usually sRGB and not RGB if they are using the Fuji Frontier machines) and also to be aware that as the print is viewed in reflected light is will generally look darker that the transmitted light image on your computer screen.
Also, as projected images are viewed using the sRGB Colour Space, there is little point is submitting images in the RGB Colour Space (or with no colour profile at all) if you expect to see no changes from what you saw at home on your monitor.
An RGB image can look quite “muddy” sometimes when projected in the sRGB Colour Space. Also you need to be aware that many monitors cannot even display the wider range of colours encompassed in the RGB Colour Space.
Having said that, in our competitions one of the most common problems as that some images do not seem to have had the most basic of “Levels” or “Curves” adjustments. They do not exhibit a good range of tones – from black through to white – and they lack contrast. Consequently they look “flat” and/or “muddy “ when projected.
More to the point, without a calibrated display for your monitor and the use of an appropriate colour profile for your image, then it becomes a matter of luck as to whether your print or projected output actually matched what you saw on your own computer monitor.
We are not promoting the ColorMunki, nor suggesting that everyone should rush out and purchase one, but hopefully hearing the information that will be presented on the importance of Colour Management in dealing with your digital images then you will be in a better position to decide what is the best approach for you to follow.
Sanjoy is organising an “Unrestricted” licence for our ColorMunki software so that GCPS members can borrow the calibrator and install the software on their own computer and carry out a calibration of their own equipment (monitors, printer and paper combinations and projector if you have one).
Obviously it is not going to be practical for 70 members to be carrying out monthly caliubrations of monitors and printer/paper/ink combinations on a monthly basis using the one calibrator. However we plan to make it available to GCPS Members to use for a day or two at a time.
No doubt Sanjoy is hoping that some people will subsequently go out and purchase one of their units.

Colour Management Information:
There is also a recent series of articles Introductory Articles on Colour Management on photo.net (http://photo.net/ ) by Jay Kinghorn on Colour Management in which the X-Rite Eye-One Display and ColorMunki are both discussed.
Part 1 – Colour Management Overview
http://photo.net/learn/digital-photography-workflow/color-management/
Part 2 – Monitor Profiling
http://photo.net/learn/digital-photography-workflow/color-management/monitor-profiling/
Part 3 – Colour Settings
http://photo.net/learn/digital-photography-workflow/color-management/configure-color-settings/
Part 4 – Printer Profiling
Yet to come
I have these first 3 Articles copied and formatted into Word documents for easier reading if anyone would like a copy.
If you produce digital images, and are interested in learning something about taking control of your process, then come along on Thursday 5th March to hear what these people have to say. Hopefully it will be worth your while and at just $5 admission to help cover costs it is much cheaper than attending a seminar in Brisbane!
