Lots of Approach Vapor for Video

Seattle is a place where you can get a fair bit of humidity at certain times of day. Earlier in the day, there might be a lot of cloud but it will burn off as the day goes on and you have some sunny afternoons and evenings. Watching the planes on approach to SEA on days like this can make for some rapidly changing conditions. I was watching a bunch of jets heading towards SEA as they came through the clouds and into clear air. They would be leaving trails in the cloud base behind them as they went but would be trailing their own little vapor fields behind them.

The conditions didn’t last long and soon the clouds were almost gone and the amount of vapor that they were pulling was minimizing. The vapor was clearly aligned with the flaps on the wings so you could see where the air was being worked the hardest. I did get some shots of them for this which I shall share later but the way in which the vapor puffs and dissipates is best seen in video, so I shot a bunch of that. Most planes were coming directly over me but a couple of the wide-bodies were going to the inner runway so were offset from my location.

Sentimental Journey In Damper Conditions

Leave a reply

Glorious weather had greeted the B-17, Sentimental Journey, when it came to Seattle. The following week, it moved up to Arlington but was not so lucky. The skies were pretty overcast and the air was more humid. It didn’t make for great conditions to shoot a bare metal aircraft. However, many times before, I have written here about how poorer conditions can sometimes be worthwhile. This was one of those times.

I started off shooting from further up the field and, as the B-17 started her takeoff roll, it was clear that the props were pulling a fair bit of vapor from the air. Consequently, I headed further down the field for the next flight. This also provided a close look at the plane as it taxied out. The real benefit came when the power was applied. Vortices were streaming from the tips of the props and swirling back across the wings. It is always a tricky call when trying to shoot in these conditions. A good bit of prop blur is good as is a blurry background to emphasize speed but, this will result in the vortices being less defined. A faster shutter speed helps make them stand out. I tried to get a good balance with the speed I chose.

Airliner Vapor In To SEA

If you were to ask people what characteristic Seattle would be known for, I suspect a fair few people would tell you it is rain. It is true that we have damp winters here but summers (while a little late in starting) are actually rather dry. However, we can still have some humid conditions which can be good for forming vapor and, if you watch the jets heading in to SEA, you will often see vortices streaming off the flaps and the occasional puffs of moisture above the wings.

Occasionally, the conditions are just right and you get a lot more vapor. Better still, if this happens in sunny conditions and the planes are slightly backlit, you can get some lovely rainbow effects showing up. I got lucky with one such day. Asiana had an A350 coming in at this time so I was treated to some interesting effects. A Lufthansa 747 and CargoLogic 777F also arrived but I decided to go with video on those to show off the fleeting nature of the vapor is it formed and dissipated.

Polarizing the Overfliers

Leave a reply

I was in a location where a couple of the departures from SEA were overflying me. I happened to have the camera to hand (of course I did) and I had the polarizer on there at the time. I had an Alaska Airlines 737 (what a shock from SEA) and a Hawaiian Airlines A330. I grabbed a few shots. The thing I like about the polarizer is cutting down on the glare from the white fuselages but they were still pretty bright. The rest of the sky was darkened considerably and, when editing to address the white fuselages, even more dark. I quite like the deep and moody look it gives to the shots with very little editing involved. Both jets pulled some vapor as they came through the same area so clearly there was extra moisture in that one spot. Maybe it was a thermal?

Misty 330s

While at Boeing Field, you get a steady stream of traffic for SeaTac overhead. With Delta’s substantial presence at Seattle, the right time of day can mean a few widebodies. The A330 is a big part of their operations and we currently get the old and the new with the -300s and the -900 neos. The conditions looked pretty clear above me but there must have been a lot of moisture around because the jets seemed to be pulling a bit of vapor with them and going in and out of clouds that they seemed to hard to see without them there.

I played around with the processing a bit to see what I could do to show up the moisture more effectively. It gets a little more interest out of a shot that would otherwise not be worthy of any note.

Damp Days for Floatplanes Means Prop Vortices!

Leave a reply

A couple of Kenmore Air planes departed from Kenmore while I was at Log Boom Park. The conditions were pretty damp and humid (and were about to be joined by pretty heavy downpours of rain!). This meant the departing planes had a good chance of pulling some streamers from the prop tips. Sure enough, when the Otter took off (and it started the takeoff run a little early which helped the shooting angles) the prop was streaming some vapor. The shape of the cone of the tip vortices as they flow across the fuselage was quite interesting.

A little while later (and just before the downpour began), a turbo Beaver came out. It, too, pulled some nice vapor from the prop tips as it accelerated across the water. A bit of a cross wind was apparently coming in (no doubt related to the impending storm) and they got airborne one float at a time. At this point we retreated to the car – but not in time to avoid the rain entirely!

Lots of Prop Vortices

Leave a reply

Departure day at RIAT was a bit overcast, much like the majority of the show. The damp atmosphere did have the positive effect of meaning many of the more powerful prop aircraft were pulling vortices from the tips of their propellers. This was most obvious earlier in their take off runs but you could get a pretty good view of it even head on from where I was sitting in the FRIAT stand. Here is one of the Hercs that was beating the air into submission.

Damp Air Brings the Vortices Out at KPAE

Leave a reply

Damp and cloudy days are not always ideal for aviation photography but they can provide some interesting options. One weekend I was up at Everett when they were approaching from the south. The jets broke out of the cloud at quite low level but there was some light from the side coming under the clouds. The damp air meant that the jets were pulling some conspicuous vortices as they flared for landing. They were a long way off but it was possible to get some shots of them. The 747 produced vortices that were easier to see but the 787s didn’t do too badly either.

Stormy Narita

Leave a reply

The day I was flying out of Narita was not a good day for weather. Another typhoon was approaching and the rain ahead of the storm had reached us. I did initially visit the viewing terrace in the terminal but, as the rain started, I decided to head inside and go to the Delta lounge which has a great view of the runway and the ramp. It wasn’t long before the heavens opened. Departures reversed direction as the wind shifted.

The arriving jets were now throwing up huge clouds of spray as they selected reverse. Combined with the heavy rain already, they were pretty obscured. Editing the photos allows you to do a lot of work with the contrast to bring out more of the detail but the real view was surprisingly limited. Some of the shots are so hidden by rain that there is little that can be done with them. Departures also did a good job throwing up lots of water in their wake.

The amount of moisture in the air meant the inlets would often be fogged, even for the jets that were landing. Trailing vortices were showing on climb out and there was lots of vapor over the wings after takeoff. The only downside to all of this was that the cloudy background makes it harder to apprecaite the effects that were on show. It does show, though, that a rainy day is not necessarily one to be ignored from a photography perspective. You can sometimes get some interesting shots in conditions that seem very unappealing. (It doesn’t hurt to be shooting this from indoors in a warm and dry room with a ready supply of food and beverages.)

Forgotten F-22 Pass

Leave a reply

There are a lot of air shows that I have been to over the years. You think you remember them well and then something shows up in your archive of images that you have completely forgotten about. I am a member of a Facebook group that has a different challenge each week and, when I get the next challenge, I work through my catalog to see what I have that might contribute. It is an interesting exercise in finding stuff that I had forgotten about.

This wasn’t one of those challenges but I was looking for something else when I came across this shot of an F-22 pulling vapor and shockwaves as it did a fast pass at the Rockford Air Show. Rockford was a great show that I used to go to when I lived in Chicago. They always got great static displays and performers for the flying display. The only limitation was that you were pretty much shooting in to the sun.

This F-22 made a fast pass and was clearly pulling a lot of vapor as it went. I don’t know why I forgot about this sequence but apparently I did. I had a go at processing them again to see what I could make of the shots this time compared to my technique in 2009. Not an easy shot to make work but the plane is dramatic enough to make it worthwhile I think.
