Blur That Prop!

Ask any aviation photographer about camera settings and they will quickly turn to shutter speed for prop aircraft. The goal is a nicely blurred prop and no frozen blades. This requires a slow shutter speed and this can have downsides. If you are using a long lens, getting a sharp shot of a moving target with a low shutter speed can be tricky. A bit of spray and pray with the shutter button can be required. Interestingly, if you are closer to the aircraft and using a shorter focal length, things are not necessarily better. When you are close in, the different parts of the airframe are actually moving at different speeds and angular rates to you so one part might be sharp when another isn’t. Sometimes this looks okay but often it just looks crap.

I have become less focused on gaining the great blur for ground shots. Air to air it is something a lot more worthwhile since the other plane is not moving relative to you – well, hopefully not that much. Therefore, you can experiment going slower with hopefully some good results. Similarly, when I am shooting helicopters close in and hovering, I will give it a go too.

Recently, I was at the Waukegan show and I decided that, since what I was shooting was not something that I had to get (either I would have other chances or I wasn’t so bothered anyway), I would play with some really low speeds. I ended up shooting at 1/80^th of a second which, on a 500mm lens is a stretch. Needless to say, you are not going to see the failures. When I have played like this before, I have had times when not one of the shots was of any use. However, this time I did get a few lucky results – yes, they were luck. You can have great panning technique (which is not always true for me) but the math is not in your favor when doing this. Therefore, I shall be happy with the results this time around. I won’t be doing this all of the time but playing around is an important thing to do when you have the chance. Just don’t do it when you really want to have a shot you can keep.

Some Older Skydiving

Leave a reply

Another trip back in time today. I seem to be coming across older shots when looking for something else and they trigger the idea that they would have been blog posts had I been writing a blog at that time. Today, it is a bit of skydiving. The Clow Cavalcade of Planes is a great event held by a local airfield southwest of Chicago. I wrote a piece about this year’s Cavalcade previously and you can find that here if you want to check back.

A couple of years ago, I was at the event and spent a bunch of time with the team that carry out skydiving demonstrations during the show. Clow is under the airspace leading into Midway and O’Hare so there is a limit of about 3,500’ on how high they can jump from but that is enough to get quickly under the canopy. When the weather cooperates (which it didn’t this year), they jump multiple times during the day. I got shots of them prepping their parachutes, under canopy and coming in to land. I also got to go up on a couple of the jumps. The first was a bit of an unusual one. They were jumping from Midwest Helicopters’ S-58T. I was in their normal jump ship, the Cessna 182. The helicopter had a far higher rate of climb than us so, while we were airborne ahead of them, it climbed up passed us and we had to catch up. Then we orbited them as they jumped. Quite an unusual thing to see.

I also rode up in the 182 when they were jumping from it. There was only one seat in the plan and that was occupied by the pilot. I sat on the floor with my back to the instrument panel with the straps across my legs and they sat in the back. Plenty of time for group shots as we climbed and then time to open the door. It was hinged at the top and the airflow held it open. When you are sitting on the floor and that door opens right next to you for the first time, it is an interesting experience seeing nothing between you and the ground. Funny how quickly you adapt though.

Then they took it in turns to jump. There was a step on the gear leg they could rest on and the wing strut was also something to hang from. A lot of good poses before letting go. Then we side-slipped to let the door close, latched it shut and descended as fast as we could. It was a fun shoot and something I would like to do again sometime. We shall see if the opportunity presents itself again.

Updates to the Workflow

Leave a reply

A while back I wrote a piece about how I manage my workflow when bringing in new pictures from a shoot. If you are so inclined, you can read the original post here. I thought it might be appropriate to bring the topic up to date since I have tweaked the workflow a bit since then. As I mentioned before, this is not all original thinking from me. I have picked up suggestions from a number of places and then adapted them to my own needs. If they are useful to you, that is great. All of this is based on using Lightroom as an image management tool.

The basic process involves creating a series of Smart Collections for a given shoot. I have adapted these collections a little and have a basic set, not all of which are required for every shoot. However, what I have done is exported these collections to a folder on my computer so I can re-import them for each shoot and tweak them rather than start from scratch each time. For example, they all have the keywords section blank so that I can paste in the required keywords for the shoot easily.

I will initially create a Collection Set for the topic and, if this is an event that occurs more than once, a Collection Set within that for the specific date. Then, within that, I shall import the Smart Collections from my templates. In the first instance, these will have lots of files in them since the criteria have not been narrowed down but I shall then edit each one to have the appropriate keywords and, if required, the specific dates. Date Taken is the criterion I will use then, either with a specific date or a range. Of course, this does require me to have put the appropriate keywords on all of the images first including whether they are HDR, panorama or time lapse images.

The following are the smart collections and a description of what they contain. To avoid repetition, it can be assumed that they will all fit the keyword and date range criteria.

Not Rejects – All images that have not been rejected, are not marked as HDR or panoramas and are not video clips
Picks – All images that have been marked as a Pick and are not video clips
HDR Originals – All marked as HDR that are RAW files
HDR Edits – All marked as HDR that are not RAW files
Pano Originals – All marked as panoramas that are RAW files
Pano Edits – All marked as panoramas that are not RAW files
Time lapse – All marked as Time Lapse (Duh!)
Not Geotagged – All files that do not have GPS coordinates associated with them
Videos – All video files not marked as rejects
Rejects – All files marked as rejects (again, duh!)

The reasons for some of these are obvious but others are less so. The not rejects file specifically excludes any shots I have marked as HDR or panorama since, when running through the edits, it is easy to see a shot that makes up one of those processes and think it is boring and delete it. Keeping them separate from the start is important. I keep the originals and the edits apart since, when I come back to them later, it is a lot simpler to look through the finished versions without having to find them amongst the originals. Previously, they ended up in the same smart collection and, after getting bored trying to find the finished one, it occurred to me that they could be kept apart easily.

I now try to geotag all of my images. Having the folder that shows that they haven’t been done reminds me to do this if I have not done it straightaway. I have found that Lightroom has a bug (I have found more than one!) that, when you have imported a bunch of stuff, if you go to the map page, it gets a little lost and keeps the map view looking like the grid view. You can get back out without any problem but have to restart to get back to map view. If you go to map view before doing all of the importing, it seems fine then. However, this folder makes sure I don’t forget to do it at some point.

With all of this set up, it is then easy enough to get into the process I have outlined before. I go to the Not Rejects folder and render 1:1 previews of all of the files. This can take a while so I will often start it off and then go and do something else for a while. I can then come back and run through the images. I will have a full screen version on one screen and the zoomed 1:1 image on the other. This allows me to easily see which shots are not sharp or have an obvious flaw like a pole through the foreground or someone’s head in the way. A quick “X” and that shot disappears from the smart collection and I am on to the next. If it is okay, right arrow and I am moving on. This kills a lot of shots quite quickly.

Then it is a simple case of looking at the shots in Grid view, usually quite large, to see the ones that are duplicate or just plain crap. I can select which to get rid of and “X” again has them consigned to the trash. Once all of this is done, I will run a BluRay backup of all of the shots including the XMP files after which I shall delete all rejects. Hopefully that leaves me with a lot less shots to play with. I can then pick the ones I think are the best and mark them as Picks. It then leaves me with a smaller smart collection which I can go in and pay some attention to making more detailed edits.

This process continues to evolve. Maybe I shall write another update in a couple of years. In the meantime, I hope it might be helpful to someone for me to have shared it. Happy shooting!

Team SHAR

3 Replies

I have spent time with Art Nalls and his Team SHAR at various events over the years but it had been a while since we had last crossed paths. Therefore, it was good to see Art and the guys again at Gary for the Chicago Air and Water Show. This year has been a busy year for the team. Not only have they got themselves well established on the show circuit but the lack of military participation has meant a relatively modern fast jet is in high demand to fill the gap left by the normal front line fighters. Add to that, the difference that a Harrier brings and you can see why their calendar has been filling up.

I caught up with Art early in the day and ended up running some errands with him for a while. However, I didn’t want to miss other acts on the ground so left them for a while to do some other stuff. I did get back later in the day and chatted to the guys for a while and watched the launch and recovery. With the jet on the ground, I also took the time to get some shots of it while no one was working on it. On the final day of the show, I did head back to the beach to try and catch it in action too.

It was, as always, great to hang out with the team. They did a great job and closed out the show nicely. I hope it isn’t as long before I next see them!

Chicago Air and Water Show

Leave a reply

Middle of August means the Chicago Air and Water Show is back. This year’s show, like all other shows in the US, was always going to be a bit different since the US military was not going to be taking part. That means a shift in emphasis from normal with a lot more civilian acts. With no headlining team this year (normally the Blue Angels and the Thunderbirds alternate), there was a question as to whether the attendance would be significantly reduced. It is a free show so you might think it isn’t that big a deal but the sponsorship is important and that requires people to show so it was going to be interesting to see how things shaped up.

There were some jets to add some noise and speed to the proceedings. Art Nalls brought his Sea Harrier and Paul Wood brought the A-4 Skyhawk. Both displayed twice on the show days to add a hint of military jets to things. Of course, these are not operational fighters and are nursed a little more carefully than a front line jet which the pilot can swap for another if he breaks anything. However, they still are able to up the tempo a bit.

I mixed my time between the flying on the beach in Chicago and Gary airport where everyone was staging from. It is fun to get the mix of the actual displays and the activity around launching and recovering the planes. The shots are a mix of those. I got to spend a lot of time with Team SHAR and will have a separate post about that in due course. From what I saw and heard, the attendance on the beach was pretty strong, if a little down on previous years. It looks like the show does indeed go on!

Passing Airliners

Leave a reply

More on the looking out of the window of airliners theme today. This time the subject is other airliners. If you don’t stare out of the window much, you might not be aware just how much other traffic is out there. Actually, there is quite a lot. At various times you might see other jets passing in the opposite direction, pacing you at a distance and crossing your path. Sometimes they seem very close. With some of the apps that are available now, if you have wifi on-board, you can even be prepared for some of them showing up.

Here I shall highlight a quality warning. The attached shots are not great. They illustrate a point but nothing more. There have been quite a few occasions when we passed very close to another aircraft. However, those were not times I had a camera handy. even if I had, the chances of getting a good shot are not great. Even when you are close, you are really not that close. It just seems a lot closer than normal – which it is. However, you are still well separated. Therefore, to get a shot, you need a medium length lens at least.

Sadly, aircraft windows are not designed for optical perfection. Moreover, since they are pressurized and scratches are a source of fatigue which you certainly do not want, the manufacturers put a nice perspex sheet between you and the window. They certainly are not optically perfect. Now you are shooting with quite a long lens through two layers of less than perfect material. This is not a good recipe for quality shots. There we go. I have made plenty of excuses.

You are now going to get a small aircraft if you are lucky and a small blur if you are not. If it is pulling a contrail, you might do better since they can make some nice shapes. However, chances are you won’t get much at all.
