So I've got a little project going on here today and we're in my living room right now.

Outside this window is my backyard and in the backyard is a large tree to which we have

discovered there are five hawks living in and of course I wanted to get some video and some photos of these guys and so

I started to set up my gear and one thing I realized is I rarely shoot with telephoto

There are a few caveats that you're going to find with these,

mainly in distortions and how they resolve.

So what I want to do is go into Light Room and

actually show you some of the stuff that I've got and how you can get around

some of these things and more importantly how you can create your own custom

presets for lens calibration. So come on over and let's have a look.

So we are in Light Room right now and as you can see sets for lens calibration so come on over and let's have a look.

So we are in Light Room right now and as you can see the 300 millimeter lens did

get me up and close where I wanted to be with these birds and I kind of shot

throughout the day the other day and is the sun moved some shots were a little

easier to work with than others you know this one the sun was pretty much

setting and I got a nice light some of these are backlit but more challenging

than that was working with some of the
