Dear darcr0ss, I know this is not directly relevant to your post but you might want to check the last images on the post below yours: "Keeping detail in highlights, avoiding blowout with digital?" I did take a picture which was overexposed then a decent one. The lower set of images in that post shows what happens with the camera image and software. Corrections could not in a simple way recover what was done in the camera. What is done in the camera is done, essentially. I wanted to show that highlights lost in camera are lost forever. The lower set of images shows that. Other folks who are much more adept at imaging software will do better than my simple experiment. But it is worth takikng note. So, I try to be careful with any filter on camera with digital imaging. What you get is what you have to work with. I do hope this helps a bit or two. Really glad to have you here on the forum. Best wishes in all your photography. TomDart. Thanks dBgrafix for the link to optikverve. This is a great little plug-in.
