Thanks Joel for your opinion. I suppose that you have confirmed what I suspected - that it is at the limits of the printer in that particular area. In addition, as I mentioned to Giles in an off-List message, the glossy Ilford paper might have exacerbated the limitations of the shadow detail, because of either the scanner or the original negative.

Another thing worth mentioning is that my monitor is set to a lower Gamma than normal Windows Gamma. I use a Mac (normal Gamma 1.8), but I have set the Gamma to 2.0 to be halfway between the 2 system standards. I think that what I have just written is correct, but I am willing to be put right if not.

I was given a book called "Perfect Exposure" for Christmas; I hope to learn enough from that to make better exposures, ones that will have less testing shadows as John L was kind enough to confirm.

Cheers

Chris

I used the photo at

as the cover for a Christmas card recently and it gave me some problems. The shadow areas, particularly around the baby's head came out with a different reflectivity from the remainder of the photo. In addition, the print showed coloured grain around the baby's forehead (and in other areas).

Chris,
In my system, this sort of image loses so much detail in the shadows on my monitor that I can't be sure of what the printed image will show, particularly in the shadows. (This is not a criticism of the photo, but of my monitor, and perhaps all monitors.) The inkjet print in my experience always shows a little more shadow detail than the monitor, but it doesn't mean you will always like what you see. It often requires pulling the curve a little to deepen the shadow to get the right effect in the print. This is not what you want to hear concerning this image, however, I think.

If the shadowy skin textures are grainy with a lot of red, this could also be scanner noise. This kind of noise will also be exacerbated by sharpening.

Another factor may be the crossing over from CMY ink to K (black) to get the proper shadow tones. In effect, the Epson print algorithm combine the three color inks to print darks until it starts to incorporate black. The transition is incredibly cunning and effective, but this kind of image may be right on the crossover point.

I don't think there is anything wrong with your printer or print resolution.

Joel W.
