I found out about HDR almost immediately after buying my first digital SLR a couple years ago. But then, Photomatix just wasn't what it is today. I tried a bunch of times, but my results never came out anywhere near what I was seeing on the Flickr HDR Pool and I gave up. After that, I tried landscapes for awhile and it was all ho-hum sunsets or sunrises, or views of the hills around here that gets so old so fast. I can't even look in the Landscapes forum much anymore, being so burned out on sunsets over water. 
Then I found the birdies and found I could get some pretty respectable shots, especially at the park feeder I go to, where they will land on you if you have food in your hand. I have spent two years now setting up my yard to attract birds and have shot 42 species of birds, right here in my own yard. And seen even more, but I only count the ones I have pics of. And then there are the Eagles I can shoot from right downtown when the river is frozen over and they are forced to fish from the only open spot for miles around. A captive audience so to speak. 
But now, while not burned out on birds, I want to point the camera at other things, and now I have finally figured out Photomatix, and this brand new version released a few days ago really puts out some excellent renders. I find myself going over in my mind what to shoot tomorrow, or today when I am done with work, what will look good as an HDR, what not to bother with.
