I'm thinking of (maybe) blue toning a series of B+W prints in order to make them look like cyanotypes. Here's the deal. I've spent the last 6 months or so working for an aging manufacturing company and been taking pictures of the place. Also, the management was gracious enough to let me peruse the company's early photographic records, dating from 1893 to maybe 1925. These images were all printed as cyanotypes, presumably because blueprinting materials were on hand for copying technical drawings at the time. So to keep the new images sort of in line with the old, I'm considering using blue toning in place of true cyanotypes. I've ruled out proper cyanotypes as I don't have the tools and experience to do it and limited time (and funds). So is there a particular method I'd get the most "cyanotype like" results from? The short handful of prints I have blue toned in the past have ended up with nearly black shadow areas, unlike a cyanotype. Otherwise the results are similar enough that I'd accept them visually. What do you all think?
