Which Do You Prefer and Do You Care?

As mentioned in other posts, I have been playing around with lower shutter speeds when photographing planes at Boeing Field.  Getting a blurry background to emphasize the speed of the plane is the goal and it also removes some of the annoying distractions that a cluttered airfield can provide.  I use filters to reduce the light in order to get the shutter speed down without having ridiculous apertures.  Naturally, I end up with a bunch of blurred photos which get deleted but the selection process for the keepers is what this post is about.

I have some photography friends that don’t like the effect that the differential speeds of the parts of the airframe have on sharpness.  A sharp nose might mean a pretty blurry tail since the relative motions as I pan are different.  When I am filtering through the shots, I often “focus” on how the nose looks since it is like having the sharp eyes on a wildlife shot.  I care less about the tail unless it looks terrible.  However, getting the middle of the airframe sharp might result in a sharper overall shot even if the nose is a little blurry.

These are the things I was thinking about with these shots of a 777X landing at Boeing Field.  The reason for the post is to see what matters to other people.  These shots are a mix of which part of the airframe is sharp and which bits are more blurred.  I may spend a fair bit of time deciding on which is best, but I wonder whether anyone looking at them is going to like the same things as me or will even care about it.  Maybe the composition of the image is all that they care about, and the pixel peeping is irrelevant.  I would really appreciate feedback if you have an opinion.

Dropping The Shutter Speed For Fun

One weekend, I was at Boeing Field awaiting something interesting.  There was the regular traffic of business jets and, since they were pretty standard fair and the light wasn’t great anyway, I figured I would play with dropping the shutter speed super low.  The R3 is great for this because I can select a frame rate of 30fps if I want.  When shooting with silly shutter speeds, really high frame rates increase the chance that I might get something that isn’t terrible.  Technology overcomes lack of talent!

I was dropping down to 1/50th or 1/60th of a second for some of the arrivals.  I was using a polarizer to take out a load of light to allow such low shutter speeds on a sunny afternoon.  It also didn’t hurt to reduce the glare with the sun so strong.  Most shots were worthless but there were a few that came out okay.  Full size there were more acceptable ones but, since I was experimenting, I focused on the ones that were really sharp.  Such low shutter speeds do result in parallax issues which is not ideal, so I tend to look for the sharpness to be on the front fuselage unless the plane is going well away from me.  There were some 737s on test too, so I played with the same techniques for them as well.  Maybe I shall go even lower at some point.

Life Flight PC-12

PC-12s are a common aircraft in the North American aviation scene so this one is nothing special.  Seeing one on approach, albeit in nice light, is not cause for much celebration.  However, it does mean that, with the light on the nose and a prop spinning up front, it is worth dropping the shutter speed and getting some prop blur.  If I try and fail, I haven’t lost a shot of something that I wanted desperately to get and, if it works, it’s a bonus.

Q400 Full Disc On The Props

I took this a long time ago but just came across it again.  I was under the approach path for SeaTac and one of the many Q400s that come in and out every day was setting up on final approach.  Since it was nothing special, I figured a low shutter speed was in order.  With the light on the front of the plane, this should show up the prop disc nicely.  It worked out pretty well.

Shooting Slower Landing Shots

One evening, I was shooting at Boeing Field.  The light was lower in the sky but it was still pretty bright.  The thing with corporate jets is that they are often predominantly white and the brightness of the jet with a darker background can make for more contrast than a camera sensor can adequately deal with.  You can sort out things in post but it is often too bright.  I figured I wanted to try and reduce the glare on the jet and that the polarizer was a good way to do it.

This has a second outcome.  Taking out that might light allows the use of slower shutter speeds without having ridiculously small apertures – a sure fire way to find every bit of dust on the sensor.  Since I was shooting bizjets at Boeing Field, things weren’t terribly special so I was happy to play around with going down to lower shutter speeds.  A boring side on landing shot is a bit more interesting when the background is blurred and the sense of motion is enhanced.  I need to practice this a bit to use it more often since it makes for a more interesting shot which I want to be able to use on something a bit more special.  Definitely need to lower the shutter speed further.

Why Not Go For Low Shutter Speeds For Fun

A holiday visit to Paine Field saw that something interesting was heading for departure.  It was unlikely I would get across the field in time to catch it and I didn’t.  However, since I was there, I thought I might as well hang around for a bit and shoot some departures.  There were a few piston types heading out as well as a PC-12.  Since none of them were too important to me, I decided to play with shutter speeds around 1/100th of a second.  With the 500mm, this doesn’t result in a high keeper rate.

It does provide a lot of prop blur which was the point since, with no background, you aren’t getting any sense of speed.  It was more a case of seeing what I could get and having some panning practice.  When looking at the shots on the computer, some of them are clearly junk without much inspection.  Others look okay until you get zoomed in.  A few of them are sharp even zoomed right in and they are the ones that don’t get culled.

Wrong Settings on a Vintage Car, But…

While hiking through Moran State Park, we came up to a road.  As we got there a vintage car of some sort was coming towards us.  Annoyingly, I had changed the camera to its base ISO to photograph some waterfalls and hadn’t reset it to auto ISO.  It was dark in there so, when I shot the passing vehicle, the shutter speed was way too low.  It means the shots were blurred but it actually wasn’t as bad as I had expected.

Ducks at Low Level

While walking along the Sammammish River Trail, a couple of Mallard Ducks flew by me at low level.  I pulled the camera up at short notice to get a shot.  No time to change the settings so this is what I got on the spur of the moment.  As it happens, the shutter speed did a nice job of blurring out the background and making them look super speedy.  I kind of like it!

The Conflict of Sharpness and Prop Vortices

Damp days can make for great prop vortices on takeoff.  However, I have been feeling less than satisfied with my results recently.  As I was going through some shots, I made a discovery that should probably have been something I worked out before.  I like to have a good amount of prop blur so drop the shutter speed down when I can.  I go with a high frame rate with the aim of getting a good sharp shot amongst the more blurry examples.

As I go through the shots, the sharp ones have okay prop vortices but not great.  Then I will come across some really nice vortices but the shot is otherwise not sharp.  It seems that, in panning with the plane to get a sharp shot, the trailing vortex gets blurred out.  If I am not panning well, the vortex can be the thing I have tracked better and it shows up well.  I have seen shots from others with the props almost frozen with a high shutter speed and the vortices easily seen.

Consequently, I am going to have to make a decision in future.  How much prop blur do I want versus the ability to see the vortices well.  A little trial and error will be involved.  At least it is fall/winter so the Pacific Northwest will probably provide me plenty of damp days on which to experiment!

Dropping the Shutter Speed in Bad Light

My cloudy Vancouver shoot also gave me the chance to play around with some lower shutter speeds.  I have done this for the turboprops before but this time I decided to play with some of the jets.  A really low shuttle speed can blur out the background and give a nice impression of movement but it is a problematic shot to make.  You don’t want to do it on something that you are keen to get in case you get nothing!  It is also something that results in very small apertures if there is much light which can make for a lot of dust spotting in post!  A cloudy evening is a good time to try and a bunch of boring regular jets are good targets for a trial!
