Sentimental Journey In Damper Conditions

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.

Damp Days for Floatplanes Means Prop Vortices!

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!
