moiracoon woke me up when she came back to bed after doing her baking. I found myself unexpectedly semi-conscious around five o' clock this morning. After enjoying the opportunity to snuggle against a warm body under fuzzy blankets for half an hour or so, I got up and looked outside. When I realized that if I hurried, I could catch the trailing edge of dawn by the lake, I jumped into velvet tights under a pair of blue jeans for warmth, put on a velvet shirt under my polar-fleece jacket (we have a lot of velvet 'round here), and, tripod and camera in hand, drove the ten blocks to the lake. I parked on the side of the street that borders the park at the lake's edge and set up my tripod against a snow bank.
I mentioned high dynamic range photography a while ago and have been dying to try some, so I thought I'd give it a shot, so to speak, here. I picked three different scenes and bracketed each of them with five exposures from -2 stops to +2 stops in increments of 1 stop. My hands, despite the fingerless leather gloves I wear to operate the camera in cold weather, were numb by the time I was done. It's cold at the shore of a great lake in winter! I'm going to find some stretch nylon gloves or similar to wear to Gary. Something I can feel camera controls through but that will cut the wind. Then I'll wear the leather gloves over them.
I made it home and played around with merging images in Photoshop and adjusting tonal curves and sharpness. The results are .
First, the 'correct' exposure with only sharpening applied:
Secondm, the result of my attempt to merge the five exposures:
Ok; clearly this is going to take a bit of practice.
I think it may be that, despite the pretty sunrise, this scene doesn't actually have anything that's enough of a highlight to really benefit from HDR treatment. I mean, I can see how the tonal range has been expanded here, but I'm not sure how much that really gains me. Of course, it looks like I totally blew the color correction when I stepped down from the 32-bit HDR file to a 16 bit file too. Oh well; practice makes perfect, and I may try playing with the same conversion with various settings to see how it comes out.
I think that, due to the brightness of the snow, my camera didn't meter the scene correctly either, so that doesn't help. I think the exposure at +1 EV looks notably better than the 'correct' one above anyway.
