Jay MillerAdam--My view on the pinkish coloration is that it was a problem in the development process. I only remember seeing it in 1889 and 1890 cards. It isn't just pink that shows up; I've seen purple (which actually looks really nice) coloration on sharp pictures unlike the faded pink look. Oftentimes the 1890 cards have a brownish pink light photo. I've always thought of these as negatives which reduce the appearance and thus the value of the card. They certainly are not a positive. I believe that grading companies should ding cards with less attractive photos due to these problems.
As to angle cuts I've seen them in all directions. Again, these are a negative but, for me anyway, not as significant as a pink photo.
