I just did a comparison of Epson Premium Semigloss against 271 Oyster, using the curves provided with QTRgui, and got the same result, i.e. very warm brownish tint on the former. Also compared several mat papers, concluding that Hahnemuhle Photo Rag was the best. Final choices for further comparisons: 271 Oyster and Hahnemuhle Photo Rag.
