Matt is a good presenter. He has done some courses on Lynda.com. I'm sure that one day seminar would provide you with some good information. But the problem with one-day seminars is that they cram so much information into one day that I find that I forget about 80% of it. Personally, I think spending $25 for a month on Lynda.com would probably give you a much better foundation to work from. And the YouTube videos are good as well. You might also look at Adobe.tv. There are a lot of excellent tutorials there as well. I'm not saying that you shouldn't consider going to that seminar. If you aren't familiar with Lightroom, I think these other alternatives would be better to start with. But if money isn't an issue, and you have the time, I'm sure you would pick up some excellent pointers at the seminar.
