Digital Photo Printing Worksheet -- CGI Edition
Back in December, I posted an Excel spreadsheet that helped people determine the largest print they can make from a given digital photograph.
I was hoping to create a CGI version of the worksheet so that people could just do it online and not have to bother with Excel. My buddy Bob crafted up a quick-and-dirty Perl script to do just that. After some tweaks, I'm happy to make version .7 beta available here:

Since the script is still in beta, it's not quite finished -- I'd like to make it friendlier to the 85% of the world who doesn't use English units as well as make it a bit more visually friendly (I'm considering adding some My Little Pony graphics).
If you compare the recommendations made by the Excel spreadsheet with those made by the script, you might find some differences. I improved the calculations in the script version and haven't yet updated the Excel spreadsheet, so consider the web version to offer better advice.
If you're curious about how I calculate the recommendations based on image size, pixels per inch, and viewing distance, check out this excellent tutorial on the science of optical resolution. If you're still curious, I'll send you the script.
