Somebody will be along soon with a fix…
However, this sort of thing can happen if you use wide angle or telephoto converters, and especially if they are not centered exactly on the lens. Also, filters and lens hoods can cause it.
The worst vignetting happens at shortest focal lengths, so try to zoom in a bit.
Ted,
What version of Photoshop? if CS, then use the vignetting correction in the RAW-converter.
Remember to correct the corners only; sky gets darker towards the zenith.
When an older version: I did that in 7 by experimenting with a feathered elipse selection, that was inverted, then lightened up a bit with curves.
Always do these editings on a layer; better methods may cross your path in the future and layers are easely discarted.

Ted,
make forground color white
layers>new adjustment layer>levels (or any type will do) ok,ok change layer blending mode to screen
image> adjustments> invert
use the eliptical marquee to select the area where viginetting does not occur selection> invert
choose the greadient tool
gradient tool transparency check box checked
choose the transparent to white gradient
check the reverse checkbox
choose the radial gradient style
draw a gradient from the center of the image to a corner change opacity to taste
you can use a soft brush with a low opacity to paint white on the layer rathe than the gradient

Thanks to all. I will experiment with these ideas.
