If you're part of the filmmaking stuff community, you probably saw my email about a DSLR resources that I was evaluating.
After sending the email, one of our readers (named Jonathan) responded with another good recommendation. So now instead of just one DSLR resource, I can provide you with two.
1. http://www.HdslrActionGuide.com – Overall, it's a no fluff guide for any DSLR filmmaker who wants to learn how to use his or her camera. It includes modules on how to get the most out of your camera. You can grab it for a few bucks and the creator provides some easy to follow videos.
2. http://nofilmschool.com/dslr/ – This book details both technology and technique. I like it because the writer is very passionate about both filmmaking and (while I don't yet know him personally), he seems to subscribe the modern moviemaker mindset. Additionally, I found his website to be full of useful “tech” tips.
Assuming you think DSLR technology is awesome, you'll probably want to check out both of the DSLR resources. And in full disclosure, these are affiliate links. So do your own due diligence prior to making a purchase.
