Ever wonder what you DON'T see at a museum? Mystic Seaport Museum understands this concept.

In addition to the numerous regular displays, exhibits and minutiae, the facility has gone deep into its photo achives to come up with an amazing new photography show. "When You See This, Remember Me: The Photography of Everett Scholfield and George Tingley" opens Saturday in the museum's R.J. Schaefer Building on the north end of the Seaport campus (the only part of the museum open until February 14).

The show explores advances in 19th-century photographic technology and techniques through the literal lenses of the two widely traveled, pioneering Connecticut portrait photographers whose careers overlapped. In addition to actual sets, backdrops, cameras and darkrooms, the exhibit includes dozens of portraits that cross all social and cultural demographics of the time.

The exhibition runs through April 28. Hours are 10 a.m.-4 p.m. Thurs.-Sun. through March 23, then 9 a.m.-5 p.m. daily. Admission $19 adults and seniors, $12 ages 3-14, free for ages 2 and younger through Feb. 14; after that, it's $28.95 adults, $26.95 for ages 65 and up, $18.95 for ages 4-14, free for ages 3 and younger.
