Just came across your site, and so hopeful to save my material from my last photo walk. My Google search on how to improve foggy pictures brought it up.
When shooting, the associations were those of Stephen King's movie "The Mist." Unexpectedly, I also got Hitchcock's "Birds." I want to keep the fog (that was the point), but, to it, I want to add a touch of "The Shining" (to stick with the metaphor). Is there any way to make the fog lighter, whiter, brighter, like on those "classical" fog shots (for example, of Golden Gate Bridge wrapped in morning fog). Yet, I still want the feel of gloom, especially added by the birds (which almost looked like bats). Unfortunately, my PowerShot SD 1200 IS (my photo gear of the moment) does not shoot raw files. Neither can I shoot long shutter in daylight. (That would have curled the fog into nice cloudy fixtures.)
I am new, and just learning how to trick my machine's auto mind into desired settings. I will attach three images, but please tell me how to attach images to questions. I tried to upload through "image" icon above, but it did not go through.
I am using Adobe Photoshop CS4.
