Now I've messed about with HDR a bit.
I find it hard work and never seem to get the results I want.
Stink seems to do a lot better with it - stunning images.
If you're thinking about it have a look through this tutorial and feedback your experiences. I'd love to know how people get on:

I had a go at HDR last night but cheating and using one image edited to different exposures. I'm not happy with them yeat ether. I'll have a read nd see where i get too.

As per that tutorial it notes that you will not get good HDR images from one RAW image where you walk the exposure up and down and then combine. I have no idea why.

Yeah it must be to do with information captured in the image. Also when i took mine they where in Jpeg format too oops.

comes down to the camera / RAW data, a single shot HDR is only ever going to give you a range that reflects the range of the sensor and even then part of the image that's been clipped is going to be guess work for the software, if you've got a scene with a low dynamic range then it can improve the shadow and highlights but not to the same level with proper bracketed shots, simply comes down to the information available.
Regarding the tutorial, I've not read it through fully, but looks to be more of a guide of when to use it and when not opposed from this is how we created this image.

I've always found the HDR feature in Photoshop CS5 pretty good at converting single images.
May not look as good as 3 seperate images with different exposures, but does me :smiley:

My OTT go at HDR. Still using one image but taken in RAW. I love the over the top effect :smiley:

out of interest and as an example I threw together 2 HDR images this morning, one 5 bracketed (on the left) the other the Middle exposure of the 5 (on the right).

Here's a 100% crop to show the difference in noise between the two images
NB the origonal images were shot at ISO1600

HDR is always one of those things that i still now have trouble getting my head around, more so in the sense of 'how' to get the final image looking enhanced but not over the top
There are so many different ways to get a HDR image to look how you want
the method i use is with layers I fin its easier to control the final result. Instead off mashing the 3 exposures together i use 3 different layers mask out the parts i dont want to show and then tweak levels / curves / shadow / highlights etc (only slightly so it retains the realistic look)
then merge the layers and tweak abit more, maybe play a bit with the doge and burn where its needed and then the sharpness etc
Ive seen some epic images people have down using photomatix and othe software
just my 2p on the subject :smiley:

Here's my attempt at HDR, the photos have been only done using photomatix, don't have PS yet.

This is the best of the lot, still slightly over saturated but not bad. The rest are very over saturated, you've got strange greens in the rock pools, cyan skies and very high blacks levels. As I guide I'd say start with one of the more natural templates and adjust the sliders from there, the images that looks unnatural look like you've started from the grunge settings which gives a very surreal look, which can work but IMO does here.
