HDR Experimentation
Friday, November 16th, 2007After work today, apart from going to JB Hi-fi to buy two albums I liked which I discovered by downloading them off a torrent site (i.e. record companies are full of crap because that’s $40 they wouldn’t have got if it wasn’t for music piracy), I had the camera with me and I tried to bracket a few shots to see what I could get with some HDR post processing.
Also, note that this is pretty much the first time I’ve ever post-processed photos on the same day I took them. So here you go, it’s the Melbourne GPO (converted to a shopping arcade after it was gutted by fire). You’ll just have to ignore that tree on the edge, I didn’t want to stand in the middle of Elizabeth St and I was in a rush so I wasn’t going to spend several minutes looking for a better spot to take the picture from. Besides, it illustrates how HDR can bring out the detail in the tree which would otherwise be a dark silhouette.

On the right, what it looks like after some perspective correction in Photoshop to get some more accurate angles which are more suitable for images of architecture. On the left, the three individual shots used to compose the HDR image. Click them for larger versions.

This post’s layout will probably be totally screwed up on the auto facebook import.
