Here's an email I got today:
What filter do you use on that 20d conversion, and which service to you pick, did you get the Deep BW IR Filter Image?
Thanks alot for the advice.
I get stuff like this all the time. Now, why would I reply? The guy has not introduced himself nor given me any reason to spend my time answering his question. Furthermore, a Google search for "Eric Cheng 20d infrared conversion" provides the answers as the first link.
I often get emails like this, asking about the variety of topics found on my website. It is easy enough to delete them, but I often wish the internets offered a "bitch-slap" feature as well.
