One of them is an all-purpose B&W effect that I use most of the time. But there’s a few others for outdoors, beaches (which is a little different than the general outdoors one, and indoor portraits). Remember, they’re portrait presets though, so they all have a similar look to them with just a few differences. But the whole point is to show off the people in the portraits so you won’t see a huge difference in each of these like you would the Lightroom 4 landscape presets from last week.
Matt comes up with the goods again. If you’re a Lightroom user and haven’t seen Lightroom Killer Tips, I seriously recommend that you visit there as soon as you possibly can!
