Vignette appears after I click on an image
I am shooting in raw with a Nikon D3x and a D700. When I click on an image for the first time in Aperture, I see a good image for a few seconds, and then the contrast lessens, the image darkens and a vignette appears. In most instances, I prefer the original image that is up there for a second or three before the image is adjusted.
I thought perhaps Aperture took a second to apply some in-camera processing to the image, but the only option I have turned on is ActiveD Lighting, which I am told has no affect in Aperture.
Anyone know what this post-import change is on my image?
Thanks in advance,
Mark
