A few months ago I did an Adobe Connect presentation for the Photoshop and Lightroom Group on Facebook.
It was a 50-minute presentation where I shared some of my favorite tips and tricks with Layer Masks. I actually took over another presenter who had to cancel last minute, so my presentation was not as polished as I would have liked it to be, but I think that you can still learn a lot from it.
The presentation was hosted by Andrew Kavanagh, who is also the founder of the Photoshop and Lightroom group. Andrew has one Adobe Connect session every month with a Photoshop or Lightroom expert. If you want to watch previous guests you can visit the archive of past guests here.
