Not much opportunity for photos these days. Here are a few fall shots.

I had to edit out an enormous flare in that last one.

I've had a debilitating fear of heights ever since I was a kid. This is probably the most daring thing I've done. K-01 on a monopod.

An interesting sunset at the beach Tuesday night. The color temperature is always a dilemma in situations like this. The color of the light was so abnormal that calibrating on a neutral surface would result in what looks like normal coloring, but is horribly inaccurate. Using an arbitrary setting like daylight 5600° would result in an overpoweringly yellow cast. I generally just wing it based on visual memory. I had to walk through a parking garage that had white-ish lighting, and this is close to the color that I remember in comparison to that white-ish lighting. It's around 3700°.

Thanks, Tim for the compliment and for the processing tip. I usually go for a sharper, more contrasty look than what I provided, and I did try something similar to what you did, but I ultimately went a different direction. What I, personally, like about the photo is the soft haziness from the high humidity. It's what gives the photo a late July feel, at least in my region. I'm not saying there's anything wrong with your approach — it's a more pleasant look. It just changes the character of the photo.

I got a particular feeling from this scene, hence the photo. To me, the photograph expresses that mood pretty well, but people tend to just see the fitted sheet over the window.

16mm, f/4.5, 3 shots, Photomatix.

Here's a non-HDR version that I processed with just ACR on my work laptop with a crappy TN screen while I was still at the conference.

Well, when I took the photo, I leaned over the edge of the wall around the roof, but braced my arms on the ledge and used the camera's built-in levels to make the shot as square as possible. I auto-bracketed three shots for HDR because I knew the street was much darker than the tops of the buildings. In LR, I used autosync to make the same manual lens correction adjustments to all three images. I also cropped out a good bit of the sky, leaving an 8/10 aspect ratio. I combined the images in Photomatix, then added some contrast in Photoshop with a process I developed for the rather flat, soft-feeling images that Photomatix tends to produce.

You can still see some slanted lines in the photo, but I was going a bit crazy trying to get everything square, so I said, "Good enough."

I had the opportunity to get some photos (with permission) from the roof of the Philadelphia Downtown Marriott last week. Sick as a dog, but I didn't want to leave this rooftop. The views aren't as panoramic as I'd have liked, but still fun. I've only uploaded one photo at this time.

What Jezza said. The white areas may be blown-out regions. I'm not sure what causes it technologically, but I've seen it a lot with tree branches: the areas right around the branches don't blow out, but as you get farther from each branch, more and more pixels blow out.

Looks good to me! What type of CA was it? I've had good success getting rid of CA from this lens in Lightroom.

Well, I just got my 10-20 back from Sigma. They insisted that there was no decentering, and that it just needed an AF adjustment. The technician I talked to said that every 10-20 is unavoidably decentered because of something to do with the mirror and the distance between the rear element and the sensor. The focal center of the image circle is in the upper-right quadrant. So I paid for the adjustment. $110 later, images are still smeared along the left edge. Sigh. I swear this lens used to be sharp along the left edge when stopped down.

Hi All,

I need to send my 10-20 f/4-5.6 in for adjustment. Has anyone else done this? If so, where did you send it. Incidentally, I'm in the mid-Atlantic region of the US.

That came out nicely, Jody. I haven't had much success with panos using the 10-20. Of course, I never happen to have a tripod when I want to, and I imagine that the wideness of angle makes it difficult to stitch the photos together properly, since a small change in angle makes a big difference in perspective.

Here's one from last Saturday. This winter, once I have no more landscaping jobs to do, I plan to send my 10-20 in for service. It just seems to be getting softer, particularly on the left edge. It's not apparent in this shot, fortunately.
