Reflection Removing – Choose Settings Wisely

A previous post had looked at what was, at that time, a development feature in Photoshop that removed reflections from images. Adobe puts development items in Photoshop first to get user experience with them before rolling them out to the software suite. Since Camera Raw and Lightroom’s develop module are basically the same, once it becomes a production item, it also makes it into Lightroom. Such is the case with the reflection removal tool.

I have used it a few times on shots, and it does work pretty well. It isn’t perfect but can be effective. I tried it out on a Typhoon that was refuelling from a Voyager. Shooting through the windows of the Voyager can be a bit tricky and the reflection removal tool can really help. I gave it a go, and the reflection was swiftly taken out. However, when I checked the rest of the image, I saw that a lot of detail in the shot was gone. It was at this point that I realised that the tool has three settings. I was on Preview. I switched to Best and, while the processing took a lot longer, lo and behold the detail was restored.

I have the overall photo above with the before and after versions for a comparison. Beneath I have two crops of the larger image with the Preview and Best settings. I won’t say which is which, but I think it should be pretty obvious. The tool defaults to Preview when you use it so, if you give it a try, don’t be put off if the initial results are disappointing. Make sure to experiment with the settings.

Taking Out Reflections – Photoshop Experimental Features

Leave a Reply

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.

Strange Sunset Light in the Sky

Sunsets are a regular theme for photographers since they provide a scene that resonates with people. I have shot plenty of them myself. However, while on Orcas, I saw something in the sky which I was quite baffled by and taken with. The sun was setting in the west and, looking off in that direction, the sky was lighting up as you would expect. However, looking directly south, the sky was doing something very odd. I don’t know exactly what was happening but my guess is that there was a lot of moisture in the sky in that direction and it was reflecting the setting sun back in our direction. It was a localized effect and quite something to see.

Dreamlifter Reflections

The idea for this was spotted by my friend, Paul, during a visit of his but we missed it at the time. It was early in the morning and the water was calm as a millpond. However, the jet was beyond the water before he spotted it. I have missed the chance since or there was not water. However, while the conditions weren’t ideal, when I saw the Dreamlifter taxiing back to the ramp, I realized the opportunity was going to be there this time.

The water wasn’t quite still and I had the long lens on the camera but a phone is a good second best these days. The jet taxied in with Mt Rainier in the background before reaching the north end of the field and crossing over. Then it was time to be ready. The phone has the added advantage of being able to shoot through the fence with no interference.

Polarizer Effect on the Water

If I remember – which I frequently don’t – I take my polarizer with me when I am going to photographing scenery. With our trip up into the Cascades, we went to the overlook of Diablo Lake and the sun was reflecting off the surface of the lake waters. I took two shots – one with the polarizer rotated to remove the glare and one with the glare in full effect. I was interested to see which of the shots I preferred when I got home. The color of the lake is very nice but sometimes the reflections are more interesting. I include both here to show just how much of a difference the polarizer makes and for you to decide which is to your taste.

Marsh Birds in SF Bay

I have photographed the birds on San Francisco Bay quite frequently. One image that I have seen many times there is hard to reproduce through still photography. That is the sight of a flock of birds wheeling around as one and catching the light on their wings as they do so. It is quite impressive to watch as the flock will flying in a direction for a moment with the light bouncing from their wings before turning suddenly and almost disappearing from view as the wings become shaded and angled away from the viewer.

The pictures here are a couple that show the difference between the two extremes. Sadly, without video, I cannot show exactly how it appears but the still make it clear just how much the visibility of the birds changes as the angle to the light varies.

Lenskirt Review

Leave a Reply

Living in a high rise in the city, I have a lot of chances to shoot things that I can only see through the windows. This has been a tricky thing to deal with over time and I have come up with various solutions with varying success. A couple of times I have thought about making something myself to be the solution but have never got around to it.

Now someone has made something that pretty much does what I want. It is called the Lenskirt. It is a black squared funnel that has a fabric sock at the base which cinches around the barrel of your lens. I has four suckers at the four corners that will attach it to glass. The idea is that it blocks any light coming in from the side and reflecting off the glass and back into the lens.

I love this idea. However, the $49 price seemed a little steep for what it is. However, i did buy one and it has just arrived. Overall, I am quite pleased with it. My suspicions about it being a bit overpriced seem valid but it does do what I want. Moreover, it handles my widest lens (the 17mm) without any problem. It allows flexibility of placement so you can shoot at an angle without seeing the skirt. Therefore, while it is a bit pricey, the alternative is something I have never bothered to do so it is probably worth it to me.

This could have other applications other than shooting through normal windows. It might be useful in an aircraft when you can’t open a window to shoot out as well. I am never a fan of shooting through something since the surface is often of poor quality but sometimes you have no choice.

Could it be improved? Yes. I would have made the rim stitched to sit flat to a surface when attached rather than having to bend out. Also, I might consider a slightly more rectangular shape given the format of shooting (although that would impact on the ability to fold it flat). It is slightly wider than deeper but given the need to look sideways sometimes, a little more width might be good. (The shot above makes it look a lot wider than it really is by the way!) I might also have gone for a less reflective black material just in case. As I try it more, we shall see if other issues come up. However, so far, a welcome addition to my bag.
