This week I acquired an 1850s 15" Lerebours et Secretan f5 portrait lens, and this is the first work I've done with it. This is an 8X10" wet plate collodion image on aluminum. I used the UVP-X formula from UV Photographics, and it was much faster than freshly made Old Workhorse! (OWH took 22 seconds to expose and UVP-X took 7 seconds in open shade on a bright day) This is an amazing period lens, with superb center sharpness and just the right amount of bokeh. A larger version of the image can be seen here.
