About the "Empress Falls" image

This image is a little different to others I have shot, so I thought I’d provide some background. Some upcoming shots of Blue Mountains canyons use a similar technique, so stay tuned if you’d like to see more.

I don’t have all the technical details to hand, but suffice to say, this is a combination of 3 bracketed shots (-2, 0, +2), all shot handheld with a Canon 20D, Sigma 10-22mm. The ISO was set to allow a handheld shot @ -2 with sufficient depth of field (f/8 I believe).

Post-processing involved adjusting all 3 raw images in Bibble Pro , and outputting as 16-bit tiffs. Because they were shot handheld, I then ran them through hugin panorama software to align them into 3 new 16-bit tiffs. Then, I fired up gimp and loaded all 3 aligned images as layers. Next, I applied layer masks to the -2 and +2 images and adjusted the masks for detail (taking the darker parts where the waterfall had blown out, and the lighter parts for the vast areas of darkness in the original image). Then it was time for some final adjustment and sharpening before outputting to a single image.

This technique is often referred to as Dynamic Range Increase (or DRI), a sibling of HDR, in a sense.
