Hi--I have done quite a bit of work with HDR this spring!. I will describe a simple HDR technique with software called Photomatix Pro ($99 to purchase full version, but you can get a free trial for one month--I strongly suggest you try it before you buy it due to issues I will touch on later)!. Essentially, compose a picture with your camera locked down on a tripod!. Then bracket your exposure--shoot one shot at -1 EV value, one at the normal exposure, and one shot at +1 EV value!. It is important to have the camera locked down on a tripod so all three images match, e!.g!., do not have movement!. You want to use aperture priority to vary your EV values, and keep the same F stop for each exposure, so you have the same depth of field for each image!. Next, in Photomatix Pro, you will select all three exposures, and you are going to combine them into one!. The image you first obtain will not be pretty, but not to worry--you are going to do what Photomatix calls "Tone Mapping"-which will allow you to set a variety of parameters, including strength, gama, etc!. Play with the tone mapping parameters to get a pleasing image!. Problems with HDR are: 1) Wind--if parts of your images are moving in the three exposures you will get a blurry composite image; 2) posterization of highlights in the +1 EV value exposure--if you are shooting in full sunlight, and the +1 EV value highlights are blown out, they will be posterized in the composite image; 3) odd color effects around the edges of intense colors; and 4) grainy colors in the shadow detail!. I am not trying to make this answer sound like an advertisement for Photomatix--but I have used this software in lieu of CS3--I also have CS3 so I will experiment and post the results if they are different!. You can take one exposure in Photomatix, and apply HDR imaging techniques to it--but be careful because you may end up with shadow detail problems!. You can also look through the Photomatix tutorial on the web, and I am sure that CS3 has a wealth of information!. With proper exposures, HDR can give you some really beautiful and saturated images, and will expand dynamic range substantially!. I use it all the time--think about it this way--if you are going to the trouble to compose an image, and then use a tripod and work it up, why not shoot sets of images and try HDR!? What I do is to shoot a set of three images of a composition first at f2!.8, then at f5!.6, then at f11!.0, then at f16!.0, then at f22!. In this fashion, when I bring my images into Adobe Lightroom, I know they are sorted by aperture at all times!. I hope this helps, and good luck!.Www@QuestionHome@Com

I am not using CS3, (still on CS!.!.!.yeah I guess I need to upgrade!), but if I am not mistaken CS3 does have a new feature that will allow you to load in several photos of varying exposures and it will then combine them into one HDR photo!.

You will just need to take various shots of the same scene with your camera at various exposure settings to expose for shadows, midtones, and highlights!. The CS3 program should then be able to take the photos and use the best of each one to create an overall properly exposed photo!.

Again, I am just relating what I *think* I know to be true!. There will probably be someone who can give you a more definite answer!.
