Hi Noyade,
I noted your comment,
Hard to tell, but does the Curtiss look kinda small?
Rough and ready but should be O.K. to tell the difference :
Enlarge the image around it to also include the F 100C.
The sun is fairly high so the shadows are pretty representative.
Note the the aircraft are parked almost orthogonally to the line of folks on crowd line.
Take a ruler.
Look in to an estimated mid -fuselage shadow of the Hun and use it as an end point. ( You can't see the entire wing shadow unfortunately) . Now track along to the right parallel to the crowd line until you intersect an imaginary line coming forward from the wingtip at 90 deg to that line ( the concrete slab lines closely approximate this). Multiply this measurement by two to get full span.
Then measure the length of the shadow of the Pusher wing on the tarmac.
The Span of a Hun is around 38.75 ft - the pusher about the same if it is a full size replica : Around 28.5 ft for a 75 % item
.
P.S.
Ian 16th :I have just checked out Irfan view with a designer mate in the imagery enhancement business. His comments:
Irfanview is an excellent standard tool. It has also been officially recognized by the EXIF community as a reference for EXIF metadata handling. A brilliant tool!
Many thanks Ian , I shall be downloading it .
