photoshop effect?

Archived from groups: rec.photo.digital (More info?)

See how this photo has sort of a "framed" effect being darker around
the edges (kind of leading your eye in to the subject) - do you think
this was done in photoshop? If so, how? If not, how do you think it
was done? It doesn't look like something a polarizer would accomplish
especially given the distribution of tones across the image.

Yes, this looks like lens vignetting. Probably the easiest way to attain it
with digital is to use a negative "correction" in the PS RAW converter. Next,
a radial gradient mask and Curves, or Levels in an Adjustment Layer. In this
case, I agree that it was probably just the lens.

I get this quite often with my 105mm f/3.5 Nikkor on 4x5. It was originally
designed as a 3.25x4.25 "press camera" lens, and Nikkor released it for 4x5.
It limits the movement in the camera, but I needed something between 90mm and
135mm in my system, so I live with the limitations. While not really a "cheap"
lens, it has mechanical/optical limitations and vignetting can occur without
warning. In this Web image, it appears that the vignetting is more prevalent
on the right-hand of the shot, especially the upper. The photographer probably
had a tilt going to get the DOF and didn't mind the darkening. As the OP
stated, it helps draw the eye to the rock.

One other thought. Since this is obviously a planned shot, this effect
could have been intentional and caused by a "spot filter". This filter
has a clear center spot on the filter and a gradual darkening toward the
edges. These spot filters come in colors in addition to ND and Grey so
with a color image the edges could fade to an orange cast (for example),
and such an image converted to B&W would have a similar effect to the
image you referenced.
