Cloudy SFO

I was in the Bay Area visiting my friend Hayman, a fellow ISAP member, so it wasn’t hard to predict what we would do with the day. we actually decided to stay locally checking out whatever SFO had to offer. We did not have the best run of luck. First the weather was a bit crappy so the photo opportunities were going to be a bit more limited. However, sometimes, bad weather can give something different so we weren’t to be deterred.

One location we had in mind was crowded and we couldn’t even park. This coincided with the arrival of the Lufthansa A380 so we already had missed one opportunity. Oh well. More strange was that everything was departing from 10 as we approached the airport. This is a very strange procedure for SFO, particularly given the wind was calm so not forcing something different. This could have given us some unusual departure shots. Just as we approached, they reverted to normal operations. See a pattern developing?

We still had some fun and got a few shots. As you can see, nothing terribly special from me. Hayman may have done better. None of these will be seen beyond this post but a day out with a friend shooting aircraft is still better than a lot of the alternatives! Cheers Hayman.

Experimenting with Multiple Exposures

Right away I must admit that this is not my idea. I know that is true of many photographic tools but I once saw someone do something just like this and I wanted to try it out myself. The question was how to go about it. I improvised a bit and trusted the camera to do what I wanted which it didn’t always do so I have learned some lessons already.

The idea is to take multiple exposures of aircraft on the approach and then combine them into one image in which the aircraft appear multiple times. I would set myself up in a position and then take a sequence of shots as the aircraft moved through the frame. My first mistake was that, because I was taking the same shot each time, I thought the exposure would not change. Not true! The camera will make some minor tweaks and this will make the whole thing less easy. White balance may also vary but I shoot in raw so syncing that afterwards is no problem.

Since I was not using a tripod, the shots are not all perfectly aligned. I took all the images in Lightroom and used the Open as Layers option to Photoshop. Then I used the auto align layers option to get everything perfectly in place. It is surprising just how much you move doing something like this! I originally thought I could just set every layer above the base one to Difference blending mode and everything would pop right out. However, that didn’t work as I had hoped. The aircraft all had an odd color cast.

Instead, I put a layer mask on each upper layer and then painted in the aircraft one layer at a time. This is more time consuming but it did the trick. Of course, if the exposures are perfectly matched, you don’t have to paint too accurately. if not, the sky color is different so a far more accurate painting on the layer mask is required.

This was a fun thing to experiment with. SFO is a great spot since you can get parallel approaches in one direction and parallel departures on the cross runway. This puts lots of aircraft in a single shot which makes it more interesting. Another time, I will take the lessons from this time and try and get them a bit better.

SFO

My work recently took me out the the Bay Area for a number of meetings. When they were all finished, I needed to write up some notes. Tapping on the laptop is something that can be achieved wherever you are. Also, SFO has a nice diverse selection of aircraft that visit. Therefore, my decision was made to take the laptop and the camera and head to Coyote Point. During the week there are less people there so it is quite a peaceful place to get some work done.

Of course, whenever something interesting made its way in to the approach, I could look up and grab a couple of shots before returning to my tasks at hand. SFO is like many hub airports in that it has a lot of the same things coming in and out. However, it has a lot of long haul traffic as well which provides an opportunity to see something a little different. This can include newer aircraft as well as those that are on their way out.

Lufthansa is now operating A380s in to SFO so catching that on the approach was a nice new thing to see. Meanwhile, the number of 747s arriving is gradually going down as they get phased out. Cathay brought one in as I was arriving. I imagine they won’t be around for much longer.

The sun was bright but the air temperature was relatively low. This meant that the heat haze was not too much of a problem. I could even get reasonable shots of the airport itself as the aircraft landed (nothing that would be publishable but not bad). A buddy was coming in with a BA 747 later in the day so I decided to move to the area on the shore near the Marriott to get some different shots. Unfortunately, this was not a good move. The heat haze to the runway at low tide was quite bad and most shots do not survive too detailed scrutiny. One to remember if I find myself back there at any time.
