This was the dramatic sky I encountered on a visit to Tarbert last September. The range of brightness between the sky and the buildings was huge and so you could only get a correctly exposed sky or a correctly exposed street. To get both, handheld, I used auto bracketing and the impressive burst speed of the Canon 7D (7+ fps) to get three exposures with minimal movement between them. The trouble is that you then have to import the three images into “photomatix” or a similar HDR software to merge them to even out the exposures. It has only taken me 3 months or so to get round to this!
Just for Julie, here are the three exposures used to make the HDR.
