TIP: Two Handy Keyboard Shortcuts
Pressing the letter
V
hides the green overlay oval from view (press V again to get it back;
you'll see I turned it off in the next step), and pressing the letter
X
swaps the Effect from
Outside to Inside (so, instead of the outside being dark in this case, it makes the center dark
and everything outside the oval unchanged).
Step Four:
The nice thing about this filter is that you can do more than just adjust Exposure. For ex-
ample, drag the Contrast slider over to the right (as I did here to +34) and this makes that
outside area more contrasty. If it wasn't already so gray (it is an engine after all), you could
lower the Saturation and then everything outside the oval would not only be darker, but
black and white (or vice versa if you increased the Saturation). Now, I mentioned in the
intro on the previous page that you could add multiple filters on the same image and that
you could use it to effectively re-light an image. So, let's do that next.
