Taking Out Reflections – Photoshop Experimental Features

I have been using Lightroom since the initial version was released. It used to be quite a simple application and anything complex was undertaken in Photoshop. As Lightroom has got more and more capable, the number of times I go into Photoshop has reduced. What I didn’t realize until recently was that Adobe uses Photoshop as the proving ground for some of the features that will ultimately make their way into Lightroom. I thought that Camera Raw and Lightroom’s Develop module were identical and they almost are. However, not quite.

In Photoshop, they have a check box to allow you try experimental features. I found out about this related to a feature designed to remove reflections. Anyone who has taken a photo through a window will know that you can get reflections off the glass of things your side of the window and these can ruin an otherwise usable image. (Photographing through a window is not a great option but sometimes it is all you have to work with.)

This feature analyses the image to see what it thinks might be artifacts from inside the window and allows you to remove them. Interestingly, the slider that comes with it can be moved either way. You can fully remove the reflection or can fully remove the rest of the image and leave only the reflection. This can be rather fun to play around with.

I was interested in what this would do for some shots I had got while inside the airport at Narita a few years ago. It was a dark and rainy day and I did try to avoid reflections but was not always successful. Some of the shots I liked most from an action point of view were the ones with light from inside intruding into the shot. These were the ones I worked with. You can judge the results. As I have the before and after versions here. It isn’t perfect but it does work rather well for an experimental feature. I hope it gets productionised soon and finds its way into the Lightroom Develop module too.

Early Morning Breeze Departure

Leave a Reply

I’ve seen a couple of Breeze airliners, but they are not operating in our neck of the woods, so they are still a rarity for me. When one of the A220s came to Boeing Field on a charter for a sports team, I was hoping to catch it. They were due out early one morning, so I was able to go before heading to the office. This did mean that conditions were going to be rather restricted with the sun only just above the horizon (assuming clouds weren’t there as well) but this would actually suit me since I didn’t want the jet to be backlit.

Sports charters have a habit of not going even close to the time that they are scheduled so I wondered whether I would be able to get the takeoff before needing to leave. Imagine my surprise and delight when they called up pretty much on schedule. Soon the jet was crossing the runway for taxiway Bravo and then heading to the departure end. As they rolled and rotated, there was just enough light in the sky to make for some rather pleasant colors, and I was really pleased with how the shots came out. The actual light levels were very low, so I shot at high ISOs. The cameras do a remarkable job of this these days but there was still a bit of noise to deal with and the latest noise reduction algorithms in Lightroom dealt with that very effectively.

Pano Experiment with a Fisheye

I will freely admit this is not my idea. It is something that I read about recently on an astrophotography post that caught my attention. I was about to make a visit to a museum where I thought I might end up taking some interior images in confined space. My 16-35mm lens was probably going to do the trick but I wondered whether the fisheye might be a better bet if things were really tight. My only concern with that is the distortion is such a feature of that lens that it might not be worthwhile.

Then I came across the aforementioned article and it talked about shooting panos with a fisheye. The article was concerned with wide sky shots for astrophotography, but I thought it might work for me too. Supposedly, stitching together multiple fisheye shots takes out a lot of the distortion while still giving you the wide reach. I decided to experiment with this in advance to see if it worked.

I played with this indoors but taking a sequence of shots with good overlap between them making sure to catch as wide an image as possible. I was using the fisheye with full frame coverage rather than the circular version of the image. In Lightroom, I had to turn off the profile correction since that plays with the shots a lot and then set the pano function to work. It combined the images very easily and, sure enough, the verticals across the shot were not all vertical and not distorted at all. This could be something I now use a lot in the future when working in confined spaces. I will need to test it for closer subjects first since I suspect that will be a lot more testing for the alignment issues in pano stitching.

Wrong Lens for Night Photography

I had a trip that took me to Los Angeles and, while it wasn’t a photography trip, I did take a camera in case I had the chance to get some images. I took the 200-800 as my one lens since I didn’t know what my shooting options would be so wanted maximum flexibility. The only downside to this choice was that this is a slow lens with small maximum apertures. As it turned out, I got to my hotel at the airport in the evening and the roof terrace was open so I had a chance to get some shots of the planes arriving to the norther complex.

Having a slow lens when doing night photography is not the ideal plan. However, you work with what you have. Also, since I know the R3 can produce some good results at silly high ISOs, I figured I would see what I could get. Even at the the max ISO of 51200, the shutter speeds were very low. While I wasn’t always at the full extent of the lens, this was not going to make things easy. There were areas where the ambient light provided more illumination for the planes, but I still went with high frame rates to see if I could get a few sharp results.

Surprisingly, things worked out pretty well. There was definitely a very low hit rate but the fact that I was getting sharp shots at all was very pleasing. The Enhance AI noise reduction in Lightroom could then do its thing provided the shot was basically sharp to start with. This combination gave me results I was very happy with. If I were to be back at this spot another time, I would definitely bring other lenses along that would provide better light gathering capabilities. Even so, knowing that this can work was a pleasant surprise.

Low shutter speed SEA shots

A recent post was focused on some shots from BFI when I was dropping the shutter speed. I had also been playing with this one gloomy morning at Seattle Tacoma International a while back. I was waiting for a specific movement but was passing time with some of the more regular movements. Since they weren’t the most exciting subjects, I tried dropping the shutter speed down to make the motion more apparent. They were really dramatic shutter speeds, but it made a slightly more interesting shot than would other have been the case.

Growlers Head Home Together

During Seafair, the USN Growlers from Whidbey Island did a display earlier in the schedule. Once they were done, the jets headed home in midafternoon. They didn’t have a long trip home so getting back to base was probably a simple call. What made it better was that they undertook a section departure and the view from the tower was really cool. The tricky thing about a section departure from a photographic point of view is which plane to track. Which one looks dominant in the shot early on and which is dominant later in the pass? It changes but tracking is harder to switch. Small problem, I know, but a little tricky.

Let’s Experiment with Silly Shutter Speeds

I have mentioned this in previous posts but the frame rate capabilities of my R3s have encouraged me to play around with some more aggressive settings. When something is a more important subject and not something I want to risk failing to get, I will be more cautious but there are plenty of other planes that I wouldn’t otherwise care about that provide a good subject to be a bit more ridiculous with. I was going down to 1/50^th of a second shutter speed. With this, I would go to the 30fps setting on the frame rate or even, occasionally, the 194fps setting just to see what might yield a sharp shot. The parallax issues are going to be an issue at this shutter speed but when you are directly abeam, you can get a good outcome. Here are some of the results from experimenting.

Struggling With the Kingfishers

There are two birds that have a good record of thwarting me when I am trying to get shots of them. The Flicker in one and some recent luck with them will appear on this blog before too long. The other is the kingfisher, and I was hoping that I might have some better luck when Nancy and I headed over to Ballard Locks one Sunday afternoon. There are quite a few kingfishers that live along the water at the locks, and they aren’t so tricky to find because their calls are loud and distinctive and are often a sign that they are flying or about to. They aren’t the stealthiest of birds.

Then again, they don’t need to be too stealthy. They are quick and agile so I imagine that they can do well when it comes to avoiding predators. I don’t know if they have many predators but good luck to them if they do since it would seem to be hard work to get one. Photographing them is hard enough! Getting good shots of them is tricky because they are small and fast. You need a long lens, but you also need to get them in the viewfinder to track them. I was making use of technology to overcome inability. The 200-800 meant I had plenty of reach and the R3 has some amazing focusing capabilities. Basically, I had no excuse because I was the weak link in the chain.

The birds were not totally cooperative, but they did give me a fair chance. Most of the time they would be flying off in the distance, but they would come close sometimes. Then they would trick me. One would take off and fly away and I would be busy track it as another flew right in front of me. I was convinced that they were taunting me. On a few occasions, though, I managed to get a tracking solution on one long enough to get focus and a few shots. The results were surprisingly pleasing. US kingfishers are not as colorful as European kingfishers and they are a bit larger, but the shape is similar, and they do make for an interesting subject. I’ll have to come back on a sunny day sometime to have another go.

F-15s Arriving for the Flyovers

Leave a Reply

Seattle was hosting two football games in one weekend. The Seahawks had their season opener on Sunday and the Huskies were playing on Saturday. The 142^nd FW from Portland sent up three jets to undertake flyovers for both games. Each flyover involved two jets so the third was a spare should one be needed. After all, these jets aren’t young. Indeed, with the wing taking delivery of F-15EX jets, it won’t be long before the Charlie models are gone.

They showed up at the end of the day which made it easier to be there to catch them. Since there were three of them, I decided to use a relatively high shutter speed for the first jet, a slower shutter speed for the second and then lower still for the last jet. That way I should get a result on the early jets and hopefully would get something more dynamic on the last one if I was lucky. Things turned out well enough and the last jet even popped the speedbrake on touchdown which was welcome. The skies were a bit red as a result of the smoke in the are from wildfires but that might have softened the light a little.

Shooting Deliberately Tight on Arriving Airliners

The arrival of the Starlux A350 has already appeared in a previous post. I got there a little ahead of its scheduled approach and, since I was playing around with using my longer lens, I decided to try shooting some of the preceding arrivals with the same lens from head on to get some tighter compositions and see just what would work before the planes got chopped off by the limited field of view. I had a variety of types coming in from the little E175s to 777Fs. They gave me some things to work with and I quite like how some of them came out. A bit of variety is good when the subjects are very repetitive.
