Others are covering this new service provided by the Firestorm peeps. So, I’ll be brief.
The Firestorm Viewer is the power user’s viewer of choice. But, even power users can’t know all the features rolled into this pretty awesome viewer. Many of the features are things you would probably use if you knew about them. So… the team is making little videos to show you how to use the features. (6 min)
This one is an example. Lots of good stuff in a short video. They say there will be another one released next Tuesday. They first post on the Firestorm Viewer Blog.
Obviously these are primarily for Firestorm users. But, some of the controls work in other viewers too.
The Camera Tools are a Firestorm and Third Party Viewers thing, at least for now.
