You did a good try at HDR.
But I would like to give you some advice if you don't mind. :)
With HDR it's best when you take tree pictures with different exposures (i'm not sure whether you did that). the sky is quit overexposed.
The best results do you get if you have a photo with clouds at the background as you have on your second try. Because the result of pictures of your first try (before and after photoshop) isn't quit big.
Hopefully I was any help to you, for i'm just beginning with HDR myself. :) I have a HDR picture in my photoalbum, if you want to see.
Also a tip i learned if you are using a single original image then using software to create the + and - ev images then dont bother just make an exact copy of the original and use the two duplicate images,
I used too create three bracketed ones in ps but then i read it makes no diff because you dont find any new detail when they are done in software, and the two duplicate technique has provided me with much better results using photomatix.
ps. not my tip actually found this tip in google somewhere.
A lot of people overdo HDR. Done correctly on an otherwise impossible shot it can have great benifits compressing the highlights and shadows so that there is detail in t he shadows without having blown highlights.
Nothing to do with lazy, some scenes have too much daynamic range for any sensor or film to capture with detail in both shadow and highlight areas,. HDR lets you take bracketed exposures and combine the properly exposed highlights and the properly exposed shadows with the properly exposed mid range areas to make a print that has detail in all areas.
I'k putting together a small example for you right now. A lot ( most ) people over do it and make very cartoon looking photos...
I'll post some exampls as soon as I get them done. I have only tried it a couple times to see what the proces has to offer. the sample I'lll post is just a sample not intended to be a great photo by any means....
