I've printed matte photo paper Fuji 50x70 cm, the picture I did with the old Rebel XTI (10 megapixel) ISO 200 and was wonderful.
A human being could not see with the naked eye, no noise, no serrated contour, no JPEG compression artifact, no chromatic aberration.
It was a portrait of the head and chest, where could see the skin pores of a 15 years old girl. The only thing I corrected was the lip that had a lack of pigmentation in the skin. If the makeup artist had used color strong lipstick, would have saved me the job, but she used transparent lipstick.
The lens I used was Tokina 16-50mm F2.8 stopped down to F4.
