Finally, another Common Lisp library
It's seems like a long time since I started a new Common Lisp project. I've been getting tired of creating ad-hoc spreadsheets to calculate some moderate complex photography formulas and started to use the Lisp REPL for evaluating some of these formulas.
That worked so well that I started formalizing these formulas into a new Common Lisp library: cl-photo. At the moment, the library has rather extensive field of view, angle of view, depth of field, hyperfocal distances, and circle of confusion calculations with flexible length units.
I'll be adding more formulas, web references, and documentation. After that, I may add an interactive web calculator, though, the calculations would likely be best done in Javascript rather than CGI or a web application. CGI has the disadvantage that starting a Lisp session has high overhead and a web application has the disadvantage of yet another daemon to maintain 24x7. A Common Lisp to Javascript translator would be a handy thing...
