Photography

 

And now for something completely different! Since 2008 I have been collecting various bits of information that I learned or read about, plus some calculators that I use every once in a while, and all of that can be found on these pages. This was never meant as a tutorial as it is a fun project of mine to serve as a backup should my grey cells fail me, and I most certainly do not have the illusion of knowing everything there is to know about photography. But since it might help others who are looking for some information on photography, I've decided to rewrite it a little bit and put it online. But it is everything except complete and it is and will always be an ongoing process, so I'll be adding new parts when I feel like doing so. Word of warning: Some parts may have a very high geek factor and contain scary things like formulas, graphs and strange schemes.
