HDR Done Wrong
This image illustrated how things can go wrong and end up right with HDR.
I ran out of the house and traveled to one of my favorite spots upon seeing this sunset. It's close by and easy to get to.
In my haste I forgot to get out of Shutter Priority mode. I dutifully shot 5 brackets at what I thought was -2/-1/0/+1/+2 EV and then went home because the magic was gone.
When I was processing the pictures in Photomatix, I realized something was wrong. It kept telling me there were exposures with the same EV. How could this be?
The camera was changing aperture to get the brackets and keeping shutter speed constant. I was shooting 1 second photos with different apertures and simply ran out of apertures the lens could go to. In the end, I had 3 photos that were different out of 5, bracketed at f/5.6, f/9 and f/13.
Needless to say, everyone, including me, will tell you this is a recipe for disaster. Changing aperture changes depth of field. You should be changing shutter speed.
But, in the end, you have to look at the photos. This is a magical shot of a blue and purple sky after sunset with a calm river and wonderfully lit building.
