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

Part 2 – Monitor Profiling

Part 3 – Colour 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!

February Minutes
03/02/09 22:48 Filed in: Committee
SUMMARY OF COMMITTEE MEETING MINUTES- FEB 2009
Despite inclement weather, there was a good turn out for the Night Shoot at Bond University. Hopefully you all managed to get some great shots for the Night Scenes competition.
Double change
The meeting place for the February outing to Brisbane on 22 February has been changed. Instead of car pooling, we will be taking the train. Departure times:
7.53am from Robina7.59am from Nerang8.04am from Helensvale
There is track work being carried out over that weekend South of Coomera Station. Buses will run from the various stations to get you to Coomera for the 8.10am. Allow more time for the bus links
8.10am from Coomera
Select the departure point most convenient for you. Meet in the last carriage on the train. We will most likely leave the train at South Brisbane. Additional information will be posted on the website.
February Practical Night.
Bring along cameras, instruction books (a must) and possibly a tripod. A general presentation will be given at the beginning of the evening, then members will break into groups so that more experienced photographers can help newer members get to know their cameras better. Q & A will be part of the evening, so have your questions ready and bring a notebook.
Members will be pleased to know that the ramp at KOA has been re-surfaced with a non-slip paint which should make negotiating the ramp safer, especially when it is wet.
The Committee approved the purchase of an external hard drive to back up Society data and important information. It will be kept by the Secretary.
From the next meeting, we will be trialling a new format. It has been noted that a number of members leave immediately after the prints have been displayed. We understand that many people work but it must be disappointing for those who enter digital images, to see people leaving before the presentation of the digital images. Therefore, the digital images will follow straight after the prints and supper will be served at the end of the evening.
A matter of some concern is the sign-on book. For reasons of safety in an emergency, it is essential that everyone present, members and visitors alike, print their name legibly in the sign-on book. Please ensure that you sign the book as soon as you arrive.
For interested members, there is a Thundercats Australia event at the Spit on 15 March. Lots of action shots guaranteed. This is not an organized event. Anyone attending will be asked to sign a disclaimer by the organizers.
The Committee is looking at having a presentation night on using the ColorMunki calibrator. A representative from interstate would give the presentation, which lasts about 2 ½ hours. It would likely be held on a non-club night. Jeff will provide further details at the next meeting.
A couple of other things to think about are the PSQ Convention on the June long weekend. This year it will be held at Caboolture. Further details on the website. Likewise, the website has information on the APSCON convention which this year, is in the lovely seaside town of Victor Harbour, South Australia on 3 – 9 October.
