These images, taken with the Sigma SD1, at which you look in reduced size, sRGB profile and in JPEG, lower resolution, are much more sophisticated, subtle, more spectacular in prints, TIFF RGB, HR and in large size A1 super. The feeling of "3D" and " physical presence " is spectacular and aroused a lot of enthusiasm in the Salon de la Photo in Paris. The ideal would be to be able to show you the picture in TIFF RGB, larger size, in high resolution, on a calibrated and quality large display with wide gamut (30")
The SD1 is phenomenal. I think the critics (Photo Magazines) are worried that a small company like Sigma might have something better; I own the small DP1 and 2, and always get positive comments on IQ.
