This Stabilization is Amazing

Another episode in the testing of the RF 200-800 for today’s post. This is more focused on the image stabilization in the lens. When shooting stills, I have commented on the slightly odd jerking effects visible in the viewfinder. I think this is most apparent when panning very slowly and I think the camera is trying to work out if you mean to stay still or not. However, one area which is really effective at showing the capabilities of the stabilization is video.

I have some footage below that is taken with the lens at 800mm and hand held. No tripod or monopod here. The rabbit was at the other end of our back yard while the bees were on the lavender plants in our beds. You can see that the image is remarkably stable. It is amazing to see it lock on so well. I have also shot some video of an F-35B in the hover, also at 800mm. It was interesting to see a lot of movement in the viewfinder for a moment and then it seemed to lock in on what it was doing and then things get really solid. This tech is most impressive.

The Hummers Are a Quick Test for the New Lens

One of the things that I knew would be a limitation of the RF 200-800 was the aperture which is a lot smaller than for really expensive lenses (yes, it is also expensive but not in the tens of thousands type of expensive). In low light, this is going to be an issue and it would be interesting to see how things worked out. When I got home with it, I was sitting on the deck when some hummingbirds started feeding on the flowers in one of our beds. This area is in shade a lot of the time so light was limited. I was rather pleased with the effectiveness of the focus, the sharpness at full zoom and the relatively limited noise related issues from the R3. This is a combination that looks like it could be quite useful for a wide variety of occasions. Not the solution for everything but definitely versatile.

What Sensors Are Behind These Panels?

Leave a reply

I was working through some shots of the 777X development aircraft as it landed at Boeing Field and I noticed a couple of the front windows were blanked out. One was a conspicuous sensor of some sort but not far behind it is one blank that looks a lot more normal but also seems to have some sensor protruding from it. No idea what they are sensing but I imagine it is important.

Initial Impressions of the RF 200-800

Leave a reply

When Canon announced the RF 200-800 lens, I was mildly interested but not too bothered by it. However, in an example of how easily a weak mind can be influenced, when I watched some reviews by those that had used the lens, I started to be more curious. The focal length range was always of interest, but the aperture range had initially put me off. The reviewers suggested that the excellent ISO performance of modern mirrorless cameras meant this wasn’t an issue. Also, while not in anyway cheap, the lens was very well priced for the range it offered.

I went to my local shop and placed a deposit for one of the lenses. This was many months ago. After that, things got very quiet. I was beginning to think that I would never see an actual lens. Then I saw something on a Canon rumor site that said August was likely to be a time when a lot of lenses got delivered. Whatever the blockage had been, there seemed to be some relief. The last Tuesday of July (stuff seems to get delivered to stores on Tuesday I guess), I get a phone call telling me that my lens has arrived. Hurrah!

After work, I headed down to pick it up. I then headed down to the water in Kenmore – a short distance from the store – to give it a quick go. I didn’t have a lot of time, but I got a quick feel for some of its quirks. Initially I was a little unsettled. The stabilization seemed very effective, but it did make tracking things that were moving slowly a bit jerky as if the stabilization didn’t believe that I actually wanted to be moving. I worried that this would be an issue. However, the images seemed to be rather sharp so maybe it knew what it was doing.

When I got home, I did spend a little time looking at the hummingbirds on the bushes. The light was very low, which should be a problem for a lens with smaller apertures, but it seemed to work very well and the images were surprisingly sharp and clean. I then took it to its first airshow. Again, results were really very pleasing. The 800mm reach was so helpful since the show line was quite distant and I was veery happy with the framing I could get. The jumpiness in the viewfinder is still something I find rather distracting but it doesn’t seem to be an issue for the images, so I guess the stabilization knows what it is doing. I also shot some video at 800mm handheld and, while there was initial wobbling, there comes a moment when it seems to get what is going on and then it is rock steady. Quite bizarre. I think this lens could be a key part of my shooting going forward. We shall see as my experience grows with it.

G700 Test Jet

I posted about the arrival of some Hunters and, in that post, I mentioned that I was there for a Gulfstream test jet. A couple of years ago, I managed to get some shots of a G600 test jet and I had been hoping to catch a G700 at some point. When one of the test aircraft filed a flight plan for Boeing Field, I finally had my opportunity. I was waiting for it when the Hunters showed up. It wasn’t far behind them that my original target showed itself.

This is the fourth test aircraft. It is in a nice paint job typical for the average anonymous bizjet but it gives hints to its true purpose by having some of the windows replaced with instrumentation. I was able to get it as it came in from the south, albeit with the usual cluttered background that Boeing Field has. Fortunately, they were operating out of the field for a few days and I was able to come back at a later date to catch it on approach from the other end.

Lightroom Noise Reduction Update Testing

Leave a reply

One of the software tools that I find a lot of people talking about these days is DeNoise from Topaz. I have never been terribly bothered by noise in my images. Modern cameras do a pretty remarkable job of handling noise and, for most usage purposes, the noise is not really an issue if it is there. I have posted my efforts with PureRAW in its various forms where I have tried it out to see how the noise reduction comes out and, while I have seen strengths and weaknesses in it, I have never seen it as something I needed to spend on.

Lightroom Classic had one of its periodic updates recently. The big new feature was their own denoise functionality. Much like my experimentation with PureRAW, it analyzes the shot and creates a new DNG file with the noise suppressed. I was curious to see how it would perform and, seeing as it is included in the price of my subscription, I have it anyway. I decided to take some shots I had recently used for the PureRAW3 trial I had done and compare with the Lightroom version.

It defaulted to a 50 level of noise reduction. I don’t know whether this is a percentage and what of but it is a scale so I played with it. I did some at 50 and some at 75 to see whether more aggressive noise reduction had detrimental effects on other parts of the image. Comparing these things and then sharing the results is a touch tricky so I have created a single image from four layers. They are the original Lightroom develop settings, the PureRAW3 version, the 75 denoise settings and the 50 denoise settings. I mask them to make the image into four sections. Then, to make it useful on here, I have zoomed in to show the borders between them to provide some sort of comparison.

The PureRAW3 result is very aggressive on noise reduction. However, I find it can make some odd artifacts in the images where details were not that clear to begin with. The 75 setting in Lightroom provided a very similar level of noise reduction to PureRAW3. It is slightly noisier but barely enough to matter. A setting of 50 does show more noise. It is still a significant improvement over the basic Camera Raw settings and very usable.

What do I conclude from all of this? First, as I have said before when testing the PureRAW trials, it provides some interesting results but it is not relevant to enough of my work to matter to me sufficient for me to spend a bunch of money on buying it. Having denoise in Lightroom now provides me with a very similar option but within the existing price I am paying for Lightroom. Therefore, I will make use of it when the situation dictates. It would be a regular part of my workflow because really high ISO shots are only an occasional thing for me but having it there when I want it will be handy.

D558-II Skyrocket On Campus

Leave a reply

The NASA high speed research program was underway in parallel with the USAF’s X Plane program. While NASA was less focused on record setting, they did have one blast of glory when they were the first to hit Mach 2. The aircraft that they used was the D558-II Skyrocket. Three of the airframes were built and they all still survive. Originally designed to have a jet engine for take off and landing and a rocket for high speed flight, the later aircraft did not have the jet and were air dropped for their missions.

One of the early airframes is now on display in the City of Lancaster on the campus of Antelope Valley college. Since I was staying nearby, I decided to swing by on the Sunday morning to see the plane. The campus was nearly deserted and it felt like I was doing something I shouldn’t but there was no problem walking around the campus. The plane is mounted on a pole in a dynamic pose towards the sky as seems appropriate. I had chosen a good time because the light on the plane was pretty good.

The Skyrocket is a sleek airframe as you would expect for something that first broke Mach 2. Being painted white also helps it look slightly futuristic. I spent a bit of time wandering around and trying different angles on the subject to make it look as cool as possible. I had just about finished when my buddy Chris showed up so I spent more time trying to get in the way of his shots!

Lightroom’s New Content Aware Remove Tool

Leave a reply

The latest version of Lightroom Classic was recently rolled out. It comes with a bunch of new additions and refinements. The one that caught my eye was the addition of content aware remove. There was already the cloning tool and the healing tools built in and these could do a lot of what you might want. However, these have now been supplemented by content aware removal. The tool is really straightforward to use but you can customize it if you like, both by choosing what area to use as a reference and also the ability to get it to try again if you don’t like the result by hitting Refresh.

The thing I wanted to try out was using it to remove power lines. These can sometimes be a bit of a pain when taking shots but, rather than use an aviation shot with some power lines crossing it, I happened to be looking at a photo I took in California of some railroad which had a bunch of lines strung across it. I wasn’t bothered about making a great shot. I was just interested in what the tool would do with the power lines. It was surprising effective. Too close an inspection would show the flaws but, if you look at the overall image, it came out quite well with very little effort. I have the before and after shots here for comparison.

A Singaporean DHL 777F

Leave a reply

The only 777s coming out of Everett at the moment are freighters. This can mean unusual airlines but not usually and I don’t head up there terribly often at the moment. However, one of the jets on test recently was destined for DHL’s operations in Singapore. Consequently, it is a hybrid of the DHL and Singapore markings. It seemed worth a look and it helped that they had taken off mid afternoon and were due back after work.

A few photographers had showed up for this arrival as was expected. At this time of year, even early evening is not the best of the light, but it was pretty good. They could be seen out as they set up for approach with Mount Rainier in the background. They touched down with the sound of the RAT buzzing in the background. I was ready to go and headed for the car, but I heard a shout from Royal and Nick that it was coming back. Sure enough, they had taxied back to do one further acceleration and abort on the runway, so we got a second chance at some shots.

Alaska Max Jets On Test

Leave a reply

I got a couple of Alaska Max jets on test on the same day recently. One was still unpainted but the colors were on the rudder and winglets so it was easy to see where it was going. The other jet was already fully painted and probably close to delivery. With me now traveling a little bit more and that travel being with Alaska, maybe I shall get to travel on one before too long. We shall see…
