Within every trade there are resources that we use to develop our skills. I want to recommend DSLR Video Shooter as one of those resources for media professionals. As a friend of the owner, Caleb Pike, I have see the amazing development of his tools over the years. Specifically, I have been sending my students through his Corporate Film Guide and enjoyed the resource myself. In addition to the guides, he also reviews a lot of great equipment. These reviews give you a way to see many of these tools in action before you purchase them.
We recently worked for DSLR Video Shooter to help refresh the site, but the real gem here is the vast amount of guides and reviews that are on the site. Hopefully you will find this as a valuable resource as you consider media equipment.
