Could someone who has a "calibrated" monitor - and with it, the necessary analytical capability, check this image, and give me whatever information may be obtainable?
Every indication I have from my own system, and from others downloading this, indicates a reasonably balanced (+/- 2c or so) gray.
Scanning a printed image of this gray card and comparing it to the scan of the card itself indicates insignificant (+/- 1cc) difference.
Ed, I'm half of what you're looking for.... Having access to a calibrated monitor but lacking the "analytical capability" to advise you.
The portrait has a definite green cast on the CM (and two non CM's I viewed it with as well). The grey reference shot however, looks fine... Good luck figuring this one out! Best. Shawn
Ed,
Where was the grey card when you shot it? In my experience it is most useful if you have the card in the target scene with some of the surrounding area also visible in the frame. In your case it would be advisable to shoot the model holding the card; balance the card and see what the rest of the frame looks like.
In the picture above the card reads just a tad over 50% grey and perfectly balanced. You don't need a calibrated monitor to sample 'how grey the image is.
Ed. Sorry for my inaccurate reporting of your previous reply in my comments on your latest critique shot. I went back and looked at your previous model shot and in fact your reply was that your findings were that there wasn't a green cast.
On my monitor this looks a pretty good facsimile of grey to me as well but in comparing it to a Grey Card I have, it looks quite a bit darker. Sorry I don't have any means of saying what percentage grey this is.
Ed, open the 'raw' file you have of this grey image. Does it read 214,214,214 in RGB values?
The best way to calibrate your scanner and monitor is use a IT8 target. You can buy those at B&H. Scan the target and compare the values to the what the target values should be. Create an ICC profile for your scanner that you can then apply to all your scanned images to correct for any shifts.
The other image you posted in the gallery definitely has a green cast to it and I don't know if that was intentional or not.
