I used Photomatrix 3.. and a steady hand!How did u bracket the exposures without a tripod? Did nt realised that, impressive.
What did u use to merge the 3 pictures photoshop or photomatrix ?
I've tried using RAW before on my 400d... but my mac with most of my software on is at work at the moment, which is annoying!It is possible to make a HDR from a single exposure. What you can do is make 3 copies of the same file, and process (using Lightroom or similar) with different exposure settings (i.e. -2, 0 +2), then combine the files in photoshop, and you can get a stunning image.
There's some good information at Canon Digital Photography Forums - Powered by vBulletin especially for Canon users. I've got a 5D, but still learning how to use it...
