I'm looking into taking some HDR shots and I was wondering if there was any special software out there to make it easier to blend the images, or if Photoshop is easy enough.
Both programs produce interesting results but i think Photoshop lets you be more expressive, as its HDR conversion is less automated than Photomatix. So if you know Photoshop and you know how to use Curves you can achieve a lot more with it IMO.
Photomatix Basic 1.2 (the free one) is windows only and very simple. Photomatix Pro is the one you want, but it costs $99
I hate saying that anyone is wrong, but.. the default photoshop hdr plugin is lacking compared to photomatix.
Lacking in what part? I haven't found anything that Photomatix does and PS doesn't. Photomatix saturates colors by default and 'compresses' the curve to give you instant, catchy results. PS on the other hand does not mess with color saturation, as you can do that later, and gives you far more control as you can adjust the curves by yourself.
If you’ve used the HDR features in Adobe Photoshop CS2, these steps will seem familiar. In my tests, though, Photomatix Pro provided more control and more pleasing results than did Photoshop CS2. Photoshop’s tone-mapping features often yield images that lack contrast and punch.
