A huge step in the right direction and acknowledgement of the still ground-breaking impact of digital photography in the design world.. No longer are you as a digital photographer or you as a designer provided with a fresh-out-of-the-camera file required to go to another application to bring in your image. Corel has long been the Swiss Army Knife of file formats and adding RAW to the mix continues this fine tradion. Welcome to X4
That is another step in the right direction. The camera and the tagalong RAW format proliferation is a never ending tide against which to swim. There is much work yet to do…

I for one would like to see eyedropper tools and color information displayed so we can gray balance straight from our RAW conversion. Those additional features would make RAW conversions sing as it is now all RAW convertes lack true professional features. For now we have a start, as long as Corel continues to have service releases for RAW the expand camera support.
David,
you said "...as it is now all RAW convertes lack true professional features." I am really curious which RAW processing programmes you have tried. There are quite a number of programmes that are totally professional and lack nothing in terms of preparing a RAW for final adjustments in a standard photo editor. Usually, the only final adjustments are manipulations rather than colour correction, or converting from RGB to CMYK. Many RAW programmes allow a reasonable choice of output profiles include Wide gamut RGB, ProPhotoRGB, etc.
Most RAW software has a dedicated white balance tool (you can click on any shade of grey, it does not have to be white) and they have a continuous RGB readout as you move your cursor over the image. Most have levels and curves and have a multitude of other features. Lightroom and PS, and DXO have a multitude of other colur adjustment sliders that can fine tune one colour without affecting other colours. Canon has a Picture Style Editor that gives similar functionality and lets you select 100 different points and adjust them to taste. This particluar editor provides a before and after readout of all selected values.
I cannot figure out what you feel is lacking?
Best regards,
Gray balance was pioneered by Lino Hell and Kodak and is now part of the GRACOL specification, it maintains that all color standards are correct when a balance gray can be maintained across the gamut. In laymen terms it means to a standard equal values of RGB across the gamut. This allows us to insert a Gretag or other color checker into an image and gray balance (color correct) the image by reading the gray patches of the color checker and adjusting the points on the curve to be of equal RGB parts. When done with precision this will color correct any image.
I have tried RAW Shooter and it pro version, Photoshops and Corels RAW converter, I own a pro version of Bibble, I have worked with Adobes Light Room on a clients work station and anyone I can get my hands on. As all RAW converters convert from three linearized gray data streams they display in a chosen RGB color space. During the conversion process one has to be able to read the gray swatches in the display color space, correct the curve for gray balance. None I've worked with can do this, they say they can white balance, so what! White balance is simply equal values of RGB at one point in the gamut. What about the rest of the image?
I have not tried the Canon but it sounds like it may be the best so far as long as it can select the read out from the specified area of the image and not just areas of the curve. It must be like PS and Corels eye dropper tool in the tone curve.
I address this in my Corel Color Management book which will be released 1/31/2008.

The attached file might illustrate what you are saying, David. It shows a RAW photo of a Q13 greyscale taken in flash light (strobe) and processed in 3 ways.
1 White balance set to NEUTRAL in Canon Raw Image Task. The grey no. 7 was sampled.
2 White balance set to TUNGSTEN in Canon Raw Image Task. The grey no. 7 was sampled.
3 2 adjusted with curves in Photoshop6. The middle sampler was set to neutral (RGB 128 128 128).
The PS sampler does not do a very good job of making the grey neutral, and a very poor one of making the other greys neutral. It is not designed to do this and is no substitute for a white balance adjustment.
Unfortunately I do not have a RAW file exposed in contolled lighting other than flash, so cannot test the Canon WB properly. Maybe the WB looks so good only becuase flash gives a pretty neutral result anyway.
I shall not have time to take another controlled photo, but maybe someone has such a photo on file already and could jump in here?

Brian, what does this have to do with grey or white balance? I think you people are really confusing color correction with white balance! White or Grey balance is done on the entire image and sets a white or grey (whatever you want to call it) point. If you change the color, white or gray balance, all colors will change where in color correction only particular colors will be changed. For example if you have a red hue on your images because you bounced the flash of a red wall, the white or color balance will not be of much help. But why am I explaining this to you, I know you know all of that already.
