Austin Photowalk

paparazzi shoot

I went to the downtown Austin gathering of the world wide photowalk. But I was rather disappointed in it. The leader said a few words and then everyone went their own separate way. I could go downtown anytime to take some photos. And this is how it felt. I decided to take my 45mm tilt-shift lens with me.

But before we wandered off, someone got a group of people together to simulate paparazzi.

The lens is a manually focused and is hard to get 100% sure that focus is exactly where you want it. I tried using the video screen with limited success. It was usually a little bit off.

I only used the tilting feature of the focus plane. It has an interesting effect in directing the eye.

I didn’t go for the miniature effect either.

horse and buggy

This cab driver was rather fond of her horse. And did not mind posing for photos.

storefronts

I would have liked the moon to be a bit more over to the right. And for it to be within the focus plane.

street crowds

Another picture just a little bit off. Hopefully, I wasn’t too intimidating on the street.

I liked this one.

frosty transformer

And this one as well. I didn’t notice how the Frost Bank building looks like a transformer.

Capitol Panorama

Austin Capitol Panorama

The capitol complex has a lot of visitors. Rather than waiting a really long time for people to clear from an individual frame, taking the shot, moving the camera, and then waiting some more, I decided to try a Photoshop technique. Which consists of taking a lot of pictures of the same frame. And then using an averaging algorithm on the series of pictures. It’s called “tourist removal.” Unfortunately, it was not perfect. The median value left visible artifacts. I had to take a more manual approach.

But that was not my biggest problem of the day. Oh, no. Instead of using a manual setting for the aperture, shutter, and ISO, I used the aperture priority mode. This caused color issues when stitched together. When Photoshop stitched the pictures and tried to automatically average the colors, something dramatic happened to the marble stonework. It gave the stone vitiligo. So sad.

Climbing Enchanted Rock

I drove to Enchanted Rock today. It’s been quite sometime since I went there previously. It was a beautiful day out. We arrived at around 8:30 in the morning. And unfortunately people started arriving in droves. Including big groups of very loud people. I had wanted to enjoy a peaceful climb. But it was not meant to be. I guess that, for the next time, I need to camp there overnight and climb it at first light.

My next door neighbor was game to come along. And we posed for this picture at around 1/4th of the way up. There was a handy rock to set the camera on. Unfortunately, the facial recognition count-down feature did not work. But the standard 10-second count-down did.

Old Planes

As we were climbing, three old propeller-driven aircraft used the rock as a way-point and performed a turn for us.

With three cloud trails forming a \ | /, I centered the picture on a bloom from some sort of yucca plant.

When I got to the top, I saw some beautiful islands of grass, moss, and cactus. They were very zen-like in a sea of pink granite.

I thought I was hallucinating that there was a dark streak in the sky. So I took a picture of it. At least the camera shared my hallucination.

Hole 3 tree

I tried a vertical panorama of a tree today and learned some things. Even turning the white balance to a specific setting, and turning the automatic focusing off, I still ran into problems. My dynamic range was blown in the last picture on the top. This caused the tree itself to go almost black. So when I tried to recover the bark, the picture turned very grainy and noisy.

So, for the next time, I will take a set of multiple exposures for each position in the range. And the aperture will be fixed so that the depth of field will not be compromised.

Swimming in Barton Springs

I went swimming today in Barton Springs. It was quite an experience! First of all it is really cold. You would think 68 degree water would not be that bad. After all, I wear shorts and short-sleeved shirts in that weather. But it took me a while to acclimate to it.

The next odd thing is there are plants living in this pool just below the surface. So when you swim, you are brushing against them and swimming through them. The pool is also quite deep so there is no standing around to rest.

It was certainly fun. I should try it in Winter when it is freezing out. I bet it would feel quite warm…

Dead Vine Pattern

They cut down the climbing vine again. Which should be no big deal. It seems to grow back in a year. Its a really fast growing vine.

It left an interesting pattern on the wall….

In the wake of devastation comes rebirth

The architect poorly designed these buildings at work. The Bradford Pear trees were placed too close to the buildings. They don’t get enough light. And the high winds knock them down. And they never get replaced!

It seems that two were taken down recently. Too bad they wont let it grow back…
