Negotiated study - Test scans with the college's Epson Perfecton V750 Pro

Yesterday I got the college's Epson Perfecton V750 Pro (in the photo department's computer suite) to work (kept on freezing on me before). The scanner takes about 5 to 10 minutes to scan (!), which is in sharp contrast to my scanner, which takes a minute. Here are the scannographs I made, and personally I'm really proud at how some came out.
