First Results
This image was taken using a two element 105 mm f/ 2.8 lens. The elements are mounted in old filter rings which made it easy to attach the two elements to each other and then to bellows for focusing. The filter rings had the additional advantage of being already threaded to accept an IR filter without any additional construction. In this case I added a Tiffen 87 filter. I used the channel mixer in photoshop to create the final monochrome image with a few final adjustments to the levels and curves.
