Overall, the first shot is still overexposed, but piques my curiosity. The second shot is pretty nice. I'm going to have to give some of these a shot myself!
GuOD, there are several software packages out there that can handle this, or are made just for it. Photoshop does it inherently, and there are also add-ons or stand-alone programs, such as the one found here:

HDR has been used mostly in landscape type photos because it really requires at least 3 shots at different exposures without anything moving.
That is kind of tough to do in our aquariums...that bottom pic took many sets of 3 exposures to get a good clear shot to work with.
just Google HDR and there are tutorials out there on the process.

Nice pics.
Don't totally agree here as you could achieve HDR witha single shot in RAW out of which you generate 2 other ones: one with increased and another with decreased exposure then you merge all three of them. This makes it easier to merge the pictures as there will be no misalignment. also it eliminates the problem of having duplicate fish appearing in your pictures.

Hi
I've tried that in PS CS2 and I'm getting error message,
I dont remember exacly what it was but I Google it and find our that this technique does not work, if it works for you please tell me what software are you using

What error message are you getting? Basically you create a new file ( size and DPI depending on your preferrence) then you moove the pictures using the move tool to this new file. Now you have a picture with three layers. You select each of those and play with it's opacity slider.
I'm not really a pro on this so I'll try to explain it as much as I can:
Digital cameras do not handle HDR as good as their film counterparts. They will clipp some of the highlights or the shadows as result.
Shadow recovery is usually possible however clipped highlights are hard/impossible to save.
A RAW picture maintains the highlights as well as the shadows more than JPG which means you can increase teh exposure to save the blacks and decrease it to save the overexposed whites.
This is why your original file has to be a RAW.
if the original one is a JPEG increaseing and decreasing teh exposure does not save the data in teh clipped highlights as it is not there anymore. This data is lost in the processing done by the camera while compressing the pictuer into a JPEG.
Any version of PS that handles layers can generate HDR pictures.
Any version of PS that has RAW converter (I believe this is only available with CS2 and 3) can process RAW images to generate a picture with increased and another with Decreased exposure.
You could also use any RAW processing software you have to generate the JPG and then fuse them in PS.
PS CS3 offers an added convenience of automatically aligning Pictures and then creating and HDR out of them. Totally convenient when using pictures shot without tripod and with different angle and some misalignment.
