Combining exposures

What would forum members suggest is the best way to combine different exposures of the same image?

I've got a photo in RAW which I've developed using Silkypix at three different exposures, with the intention of combining these to avoid blown highlights and underexposed lowlights in the final image.

I tried to combine these using the HDR merge tool in Corel PSP X2, but the result was very disappointing. The end result showing quite significant image degradation.

Is Layers the way to go? Pardon me if this comes across as a rather basic question, but I am only just developing my digital manipulation skills beyond unsharp mask, tone, saturation etc.

Hi Mhuni,
Yes, layers is definitely one way to go
Here's a pretty quick and good tutorial - http://www.ephotozine.com/article/Exposure-blending-with-David-Clapp-10929

I've done this occasionally, but also used the following other methods:
1) Use Artizen HDR (for "proper" HDR with multiple RAW files at different exposures)

2) Process in RAW but reducing the contrast and adjusting gamma to squeeze everything into a very "flat" image that has everything, but then output to 16-bit TIFF. Then use adjustment layers in Photoshop to correct tone and contrast for each region. This method has the advantage of only working on a single layer (and there are tricks that can be used!)

But... try the multiple-image-output-from-RAW-with-layers method first

I just spent 10 minutes or so penning my answer that now, that the second incarnation of this post has disappeared is lost in the eternal ether of the internet.

In short:
1.) I suggested manual use of layers and layer masks
2.) I suggested looking at "enfuse" from PanoTools (Google will help)
3.) Use gradient layers and mode soft light to brighten or darken portions of an image.

I'm p***ed off at myself as I thought "better copy what you write when you're finished as one of the two post might have disappeared"
My old pal Alzheimer kept me from doing so...

yep. what they said.
I posted a decent example in a thread titled "Damn" just the other day...link

Thanks for the feedback guys.

That link you provided looks very useful, Matt - and interesting to see the technique applied Don.

Now to see if I can do it!

Sorry about your wasted efforts Prieni - the link was bad that day (not unusual) which led me to post more than once as I didn't think the original had registered. By the way, I hear they're testing a new drug for Alzheimers. Otherwise cut down on the binge drinking and eat lots of carrots!
