RCAF Hornet Tests High ISO Performance

The later stages of the Abbotsford Air Show included a performance by the RCAF CF-188A Hornet. By the time it was performing, the light was pretty much gone. The late performance has some benefits in that the burners are more striking against a darker sky, but the RCAF display often ends with a landing with the hook lowered. I had seen this before at Chino and the same problem as happened there occurred here. The touchdown point was a long way away from the spectator line, so it was too far away to get a decent shot.

However, there was the rest of the display to go for. My current cameras seem very able to handle low light conditions. The focus might be a touch slower or less accurate as the light diminishes but I wasn’t noticing a significant problem. Also, the high ISO capabilities of current generation cameras are really impressive so shooting in such conditions is not necessarily a problem. The camera will be able to perform although that won’t compensate for a jet just not looking that good with so little light. You still have to pick your shots.

The Hornet is a good display jet with the ability to point the nose in different directions rapidly and to pull a decent amount of vapor from the air. It can turn and it can blast through, so it makes for a good show. Original generation Hornets are starting to become a rarity. It won’t be long before the Canadian jets have been replaced by F-35s. Other operators have already transitioned and more will follow. Catch the legacy Hornets while you can and, preferably, in interesting lighting conditions.

Delta/LATAM Comes in After Dark

Leave a reply

Delta picked up a few ex-LATAM Airbus A350-900s as part of that airlines restructuring during the downturn in the airline business caused by the pandemic. They went initially in to storage and then have been progressively moved to Singapore for updating to the Delta configuration. Seattle has been the location for them to come through on their way to Asia. I have missed a few but one was due to come through when I could see it. Sadly, it departed a little late from Victorville and was showing due in after dark.

Since it was an unusual movement, I figured it was still worth the effort. I would use the 500mm since it has a wider aperture and test the low light capabilities of the camera to the full. It still meant some very low shutter speeds but I let the tech compensate for my low skill levels. I was pleasantly surprised by how well some of them came out given the lack of light. Since this shoot, I did also reprocess with PureRAW3 and this improved the quality of the shot further.

Shooting at SEA After Sunset

One of the things that photographers that have only used digital cameras can’t appreciate is ability to shoot in low light conditions. When I was shooting film, you were already struggling with image quality with ISO 400 film. Early digital cameras got very noisy as the ISO got ramped up but, these days, the capabilities of shooting in very low light are truly amazing for those of us that are old enough to remember what it was like. ISO1000 black and white film was adventurous!

Now I feel quite comfortable trying all sorts of silly things. I had gone down to SEA one evening to try and get a departure that was possibly going out just before sunset. Sadly, it didn’t play ball and the sun was gone by the time it headed out. However, I was there and the camera can do silly ISO numbers so why not. It still needs to drop the shutter speed down quite low but, with a fast burst rate, the chances of getting a reasonable shot are not bad.

I figured I would play around with shooting departure shots as the last of the light was fading away. It was more about trying something different rather than aiming for the perfect shot. I did have some interesting planes to play with but also plenty of Alaska 737s. The light was pretty dim and ISO51200 is quite something to work with but the image quality is really very impressive considering what conditions you are shooting in.

Falcon 50 Through the Snow

Crappy conditions are not usually what you are after when photographing aircraft but, sometimes it is what you get and you have to make the best of it. One upside is that, if you are somewhere with a reasonable amount of traffic, you can play around with getting shots of something you weren’t necessarily focused on. While standing in the snow waiting for the Skycourier’s arrival, I did have a Falcon 50 on approach. I like the Falcon 50 a lot so this would normally have my attention already. However, crummy conditions almost left me in the car. I decided at the last minute to try it anyway.

I was really quite pleased with the patterns that the snow made around the jet as it came in. in such bad light, the landing lights are always going to be more dominant and their ability to light up the snow flurries ahead of them can work out well. These pictures will probably never be gracing anyone’s walls but I got a kick out of them when I went through them back at home.

How Low Can You Go?

The high ISO capabilities of modern cameras are a constant source of discussion whenever a new camera comes out. It was quite funny to see everyone get so excited about the multi-million ISO range on the Nikon D5 when it was announced, only to see that the high ranges were nothing more than moose with a bit of an image overlaid on them. Not a big surprise but still funny to see how much everyone was going nuts about it before the reality set in.

Consequently, I was interested to see what the new bodies I bought were really capable of. I have already posted a little about some of the shots I took as the light faded at SFO. I was shooting with a tripod and a gimbal mount to make things easier but I was also working within the ISO range of the camera. I went with auto ISO and exposure compensation while shooting in aperture priory and wide open to get what I could. However, I really wanted to see what was possible so I changed to manual mode, exposure compensation and auto ISO to see what could be done. Auto ISO is not going to use the extended ranges of ISO.

I don’t know about the Nikon cameras but the Canon cameras tend to have three extended range ISO settings at the high end. There is the highest ISO setting that it recognizes and then there are H1, H2 and H3. They don’t name them with the actual ISO settings but you know what they are based on what you see on the camera. The manufacturer does not label them as normal ISO settings because they do not stand behind them as a capability. There is a good reason for that. They are just like the highest Nikon settings. Useful if you have no option but not very good otherwise.

The same was true with my older bodies. They had a very high ISO range that was not great but it would do in a pinch. At the Albuquerque Balloon Fiesta I shot an Aero Commander in the pitch black that flew over and I saw stuff in the shot I couldn’t see with the naked eye. This is with a camera that is ancient by modern standards. I expected a bit more with the latest generation. Certainly, there is more to be achieved with what we have now. However, post processing becomes a part of the story.

My first experience with these shots was in Lightroom. The shots did not look good at all. However, there was a clue in all of this. The first view in Lightroom is based on the JPEG that is baked into the raw file. It looked okay until it was rendering by Adobe at which point it looked a lot worse. This piqued my interest. Sure enough, at the extended ISO ranges, the shots looked pretty awful. Lots of purple backgrounds. These were not going to be any good. However, the initial preview had looked good., is this a case of Lightroom not being able to render the shots well? I figured I should try going to the source.

At various ISAP symposiums, the Canon guys have talked about how their software is the one that you should use since only Canon know how to decode their shots properly. They have the recipe for the secret sauce. Since Digital Photo Professional (DPP), Canon’s own software for decoding raw files, is so terrible to use, I never bother with it. The raw processing in Lightroom (and ACR since they are the same) is so much easier to use normally and works really well. DPP is just awful in comparison. However, we are now dealing with the extremes of capabilities of the camera. The embedded previews seemed better so maybe it is possible that DPP will be able to do a better job.

You can now be the judge. Here are some pairs of shots. They are the same shot in each case. The first is processed in Adobe Lightroom and the second is processed in DPP. I think it is clear that DPP is better able to work with the raw files when it comes to extreme ISO settings. The shots certainly have a more normal look to them. The Lightroom shots look really messed up by comparison. It doesn’t mean I will be using the extended ISO ranges on a regular basis. Jumping to DPP for processing is not helpful on a regular basis. However, if the need arises, I know that I can push the camera a lot further and use DPP to get something that is okay if not great. This could be handy at some point.

After Dark! Testing the Low Light

Leave a reply

The real goal of my shoot after sunset was to see what is possible with the cameras. An awful lot is written these days about the incredible low light capabilities of the latest cameras. I am rather suspicious of some of the claims that are made so I was interested to see what could be done. I have seen reviews in which people describe shooting with ISO settings and claiming they are absolutely clean – no noise! I am imagining that there is a little bit of over enthusiasm in these claims. No one wants to write a review that says nothing much has changed for fear that they won’t get to review the next camera.

Consequently, while I do expect some improvement in capabilities – particularly given I skip generations of cameras when buying my own – I am skeptical that they will be quite so dramatic. Even so, I did anticipate some improvements from my previous bodies and I did get this. I am not talking about noiseless shooting at ridiculous ISO settings. I am able to work in a far higher range though. It is worth noting that a blog post involves relatively low image sizes so the worst of the noise becomes less apparent. Full size images are a lot more harsh. (For this post I won’t focus on a previous issue of mine which is how printing is far more forgiving of noise than a screen is.)

A tricky issue with shooting as the light disappears is the use of exposure compensation. From having some positive exposure comp during the day, as the night comes on, I go through normal exposure to having a bit of negative exposure compensation. It is dark so the shots should be dark. It shouldn’t look like daylight. I ended up playing around with the settings a bit to see whether -1 to -2 should be used. -2 ended up being a bit too much. However, it is a bit of a guessing game depending on what you are shooting and how much light there is in the background.

One good thing about these bodies is their ability to handle some post processing. If the shots were a bit dark, boosting the exposure did not bring as much noise into the shot as I would have expected with my previous bodies. I was able to mess around with them a lot more without things going horribly wrong. I am not getting amazing shots (unless you are comparing them to what you could do in film or early digital days in which case this really should be considered amazing – that’s how spoilt we have become). The contrast at night is harsh so things will always be a bit difficult. However, you can get shots in some very difficult conditions. You won’t get detail in the images like you expect in normal lighting but that really would be phenomenal!
