I have a setting in my editing package which allows me to set a camera curve for highlights and shadows. Once you have saved the profile, you can just call it up and use it to apply the hdr to correct your images. Is this legal in basic editing? I find it doesn't work on all images, but some seem to be helped by it, especially when there is a lot of contrast in highlights and shadows which sometimes hides fine details.

two thoughts.

first, HDR is not legal because you will be using more than one photo.

second, I would neve use in camera contrast. It limits your post processing abilites, and your PP app can do a better job of contrast editing.

If I am correctly interpreting what the software is doing, you're starting with one source image, and applying separate curves for shadows and highlights, but with a setting that you've pre-defined.
This is pretty much what Photoshop's Shadow/highlight tool does, and that tool has been deemed legal in Basic. I don't see this tool as being substantially different.
Edit: Which editing package is this, BTW?

American horse, I think you misread a bit...

If I am reading correctly, this appears to me to be little more than an action for a couple of adjustment layers in curves that are then labelled with the name of the camera, so can be applied to other images from that camera that were shot with similar settings.

I don't see anything there about doing this in camera... This is her editing package...

PS seems to be able to do this in CS2. I watched a tutorial on using this sort of thing on the Radian Vista.

I didn't know that Shadows and Highlights was legal in basic... damn, I'm missing out! I kinda thought that S/H used adjustment layers with computer approximated masks...

shows what I know... :)

I use photo impact pro vers. 10. You are reading it right. Once I have established a camera curve from a previous set of images, I can save it, then use it like contrast and brightness adjustments to any new images I want to adjust. I don't need to take several images once I've set the camera curve to my specific camera. It still allows me to adjust brigtness and contrast, etc, and when using the camera curve profile I have a slider scale for contrast, highlights, shadows, and midtones. So it is kind of like using tonal mapping, which I heard was okay in basic, with the added benefit of using a camera curve for your particular camera. It is not done in camera, but in the editing package.

What you describe sounds legal. It doesn't really require anytthing but a rather funny-looking curve adjustment. Your editing package is just adding the "one-click" functionality and the ability to save the setting for the camera.

OH......never mind.
