I just recently started getting into this, for some reason I had been quite unaware of it over the passed years. It works best with 3-4 seperate pictures, taken with different exposures, however I found out a way myself to make an HDR from a single photo. Though it doesn't look at good as a true HDR, I think it is very impressive still. Original picture: "Fake" HDR: The only part of my outcome that I don't like, is that the sky in the HDR looks grey, as if it's cloudy. You can tell in the original it's blue though, photo was taken at about 5:00am. If anyone's got a nice quality picture they want me to try and HDR, post it here and I'll give it a go. Need to get some practice before I get myself a decent camera.
