Hmm, not sure what happened to the text I wrote.
Sorry, I missed this and thanks. I used a Singh Ray 3 stop reverse grad for the sky, then I think I bracketed 3 shots (although I could have produced 3-4 TIFFs from a singel RAW), it's been a few years. I tonemapped the 3-4 exposures using Photomatix, reducing the amount of HDR to as low as possible, while still maintaining highlight detail in the rockpool. My aiom was to keep it as natural looking as possible, although in reality, the rockpool should be darker than the sky.
I'm not really a fan of HDR, mainly because there are so many poor examples and because I think it is used too much and has almost become cliched. There are some nice ones here though, that don't look too unnatural. This was the last shot I did with HDR, which was actually a combination of grads and HDR.

Sorry, I missed this and thanks. I used a Singh-Ray reverse grad on the sky, then used Photomatix to recover the highlights in the rockpools. It's a while since I did it, but I think I bracketed three shots and tonemapped them (although it's possible it was a single shot to produce 3-4 TIFFs from the RAW), reducing the amount of HDR as much as possible, so that it just recovered the detail, to prevent it looking unnatural. Of course, in reality, the rockpools would be darker than the sky, but I wanted it close enough to be able to view it as potentially natural.
And an earlier one that immediately made me imagine pteradactyls flying about. It was a sort of landmark image for me too, as it was one of the first images where I felt I'd mastered the lighting and used it for effect on the rocks and water.

those are some really nice shots! I'd be interested to hear some more details about how you processed that first one I like it alot (+1 for you!)
