Lightroom 2 antique greyscale conversion with the contrast dialed down. The print actually looks like an albumin contact print. The detail blocks up in the JPEG conversion, but the seeds really pop.
Here is the original grab shot with Nikon D100, ISO 200, 24-85mm @ 85 in Macro mode, f/11 @ 1/350s. Cropped in Lightroom 2.1. The color reminds me of a much better execution of the same subject by Irving Penn from ~1959. Even just doing a casual homage makes me appreciate just how amazingly good Penn is.
