The burn tool is also called the adjustment brush.
In Develop, it's in the upper right, and looks like a paintbrush.
To start with, zoom in on what you want to burn,
click on the brush,
a menu will show up, slide exposure all the way as negative as it can go.
adjust the size of the brush set flow to 100%
and brush over what you want to burn, you'll
get a very dark bit on the screen showing where the mask is. Once you
have the object masked, you can adjust the exposure slider until it
is as dark as you want.
That's the brute force way of doing it.
You can also set it to a more reasonable amount of darkening,
set the flow to a smaller amount and just brush on darkening,
until it's where you want. This way you can darken the edges
a little bit by brushing them slightly, and the center more.
Likewise, when setting the size of the brush, you can set it
to feather the edges, where the center circle gets all of the flo
and the outside circle gets increasingly less.
The third thing you can play with is the auto mask where it will
only do the brush on stuff that match the color of the point in the
center. I wouldn't worry about using that right now.
Now that I've given you a quick and easy explanation of how
to do it, I think I can count on the experts on the list to
correct me.
For what it's worth, in the darkroom, we'd do the same thing by
punchng a hole in a piece of cardboard, and exposing the print
a bit longer by moving the hole around the area we wanted to
burn in.
To make it lighter, we'd do something very similar except we'd
use a small piece of cardboard to "dodge", i.e. block the light
while we were exposing the rest of the image.
BTW, when using the adjustment brush on shots in color to de-emphasize
something in the background, in an otherwise dark room, you can
also dial down the saturation.
Thanks for all the tips, Larry!
I've always been leery of using anything beyond the very basic stuff
because I just don't have a sense for how it works. I really should have
learned all this stuff a long time ago, but I've always been completely
baffled by brushes.
It'd be great if there were a Lightroom class at one of the local
technical schools, but being such a small area, there wouldn't be enough
demand to justify it.
I'll try my hand at these tips and maybe I'll learn to use some of the
other brush functions once I get reasonably comfortable.
Thanks again!
