There are always a lot of different opinions about the colour quality of digital images when  projected.

• First of all our digital cameras have different digital sensors capturing the image and then saves according to the different shooting settings. That means that you can use different settings changing the RGB capturing during the capturing stage already.
• Secondly you may have software that again manipulates the data when you transfer the data from camera to computer. It reads the colour profile of your monitor and adjusts automatically. This is not the norm, but watch out for it. Alternatively certain program application uses its own colour settings and then adapts the image to this program's setting
• Thirdly you will then adjust the image in your favourite software such as Adobe Photoshop, Printshop Pro, Gimp or any other. Again the software will then use the colour settings of the software to adjust the image.
• You display the image onto a monitor, print it to a printer and submit it for presentation at club competitions.

The poor image has gone through so many alterations and adjustments that each time you view it on another system it looks different.
The main issue is to understand that the ICC profile used by all the various capturing and presenting devices should be in sync.
The following resources should allow you to better understand and appreciate colour management:

• Cambridge in Colour – A Learning Community for Photographers. Click the link for in depth information on Digital Photography. Click on this link – Colour Management-  to take you directly to the information on colour management. That may be more confusing than helpful informational to start off with, but it is essential to understand colour manipulation.
• In the meantime you can go to Display Calibration.com to investigate (and adjust if necessary) whether your screen displays colours correctly.  If not – correct your display or get help. You can even use different hardware applications or Spyders to ensure that your screen is set up correctly BEFORE you use any photo editing software to adjust your image. Remember that you will adjust the image to have a display that is pleasing to your eye on your monitor? It is not to say that it will print or project the same as displayed, or even if it does it is not to say that it displays correct colours.

It is important to ensure that your display is set up properly before you venture into the manipulation of images using other software.
