I've been testing different hdr software for a while now and thought I'd try two slightly non-aligned jpeg images, using Essential HDR, TuFuse Pro and SNS hdr Lite. The non-alignment came about because I didn't have a tripod with me and just braced against a lamppost.
Here are the three images.
The first is Essential Hdr, which offers to align your images.
The second is TuFuse Pro.
The third is SNS HDR lite.
These three images are not otherwise tweaked for exposure, levels or anything else. They are all straight off the hdr software, except for a resize in Irfanview.
