In working with digital images taken outdoors I find that shadows appear much darker than what I see with my eye. I have worked with a contrast blending method that causes the image to look more natural. My camera has an exposure bracketing mode where it takes two additional (one above and one below the normal) images for a total of three.

I am trying to think of a way to use blending modes with the three images so that the darkest highlight area and the brightest shadow area end up in the resultant image.

I welcome you suggestions,

Sorry, make that "succinct."

Check out the "blend exposure" plugin from Reindeer Graphics (ReindeerGraphics.com) which does exactly that. It is part of their optipix package of Photoshop plugins, works in both 8 and 16 bits per channel, and has been very favorably reviewed.

I think you need to use a tripod if you hope to blend three images together. That and the other suggestions for software should get you started. Good luck, Lynn

You can overlay the images on separate layers and then create masks to reveal different areas from each.
I have a tip on doing this on my web site.

Combine the three images in three layers, with the lowest layer being your middle bracketed exposure. Then play with the advanced blending modes available in the layer properties.
