Hi Bruce. Is it possible to post the pic before the filter was applied so we can really see the difference?
Terri, this is the pic before the filter was applied. You will notice (in pic #1) in the circumference of the filter everything remains bright; the rest of the image outside of the filter becomes darker - depending on how far down you dial the exposure setting.
Also, you can invert this effect if you wish. Bruce

I haven't used the radial filter yet, but I've used the Adjustment Brush to achieve the same effect. Set the Exposure positive to lighten; negative to darken (dodging and burning in the film days). There is more control over the shape of the area modified with the brush than the radial filter which is elliptical/round. With the brush, the area can be any shape and the intensity can be varied by using a low density and multiple passes to increase the effect where required. By contrast, the Radial filter seems a bit limited, although quicker/easier to use.

I can't disagree with Bruce's point although I have found the radial filter very useful for subtle vignettes and for blurring parts of the image. You can of course use the tool several times on an image although one should be aware of the masking effect of previous applications of the tool.
Just adding two quick hints for Radial Filter-
1. Shift+M (to select R-Filter), move mouse cursor onto image, Hold down CTRL and Double-Click left mouse button- This creates an oval that fits exactly within the boundaries of the image. Great for an easy Vignette!
2. With an oval filter defined and active (the 'dot' is dark), hold down CTRL+ALT and mouse drag the spot to another position- This copies the filter. Great if you want two areas with the radial filter the same size- eyes?
