Does anyone have any knowledge of taking one image in PSP and changing its attributes then making additional changed images to use in HDR?

I've tried going into Brightness and Contrast, but it just dont feel right.

any tips?

I tried this once and the results were less than satisfactory, it resulted in a rather flat picture. I used, if a rember right, highlight midtone and shadow changes.

Best way is to use one raw file and process at different EV settings.

Here's my effort done in the last 15min, in PSP I opened original JPG file in smart photo fix, reduced brightness by 25% then again from the reduced one, the from original plus the brightness by 25% then from that one plus 25% combined them all and the second photo was the result, in might not be what you wanted but just play with the controls and see what you get.

First photo original 2nd photo 5 combined.

Cheers Gents. I think I'll stick to taking different exposures out in the field. It is quite exciting (relatively speaking of course) to get back and see how they all look when blended togather.

As long as you shoot in RAW, you can process the file at a number of different exposure compensations to get a good series of files for an HDR run.

It's not meant to be as good as actually taking the different exposures, but, it can be a good compromise for those times that taking a series of shots is impractical, for example moving subjects or unstable shooting platform.

You don't even need to make separate files you can do alot with curves and the likes to get a pseudo HDR

The whole point of HDR is to capture a much greater range of exposures than is possible on a single image, and you can only properly do this with several shots.

If you use a single image and push the EV up you will also introduce more noise to the image. If you only have a single (RAW) image, Photmatix Pro can do a pseudo HDR image, but you are still better of working from several images. I use a 5 shot bracket at +/- 2 ev.

True, true... A lot depends, I guess, on what is meant by the term HDR

I'm only dabbling with HDR at present, so I guess I see HDR as combining source files, and playing around with curves, as... Ummmmm... Playing around with curves...

*edit*
Too clarify, I'd only use the single file, exposure compensated method if I thought that taking the 3-5 actual shots would result in to much movement between the shots.

HDR means several exposures combined, using one exposure is a pseudo-HDR technique.

5 or 7 exposures is the way to go, but it does also need the right sort of subject.
Best regards, John
