You can't really use phots stright off
If an aeroplane is photographed amid ship then the two ends will be undersized as they are further away
I didn't have Superfreighter plans so had to use prototype plans and build up the extras
The photo I used for the nose was a side on but the rear fuse on the photo was mid dorsal on the model
When scaling the nose...it was photographed for the nose side..I had to use depth and allow for the fact the top and bottom would be short.
Scaling the nose vertically meant the fuse lost about 15 feet in length do to the tail being further away and smaller

The side of a circular fuse..or the Vulcan canopy will be out on a photo
The top and bottom on the fuse is in the middle and on a 12 foot diameter fuse for example it will be 6 feet further away...so naturally the image as seen by the camera and the eye is reduced in depth to real measurements.
So the model, made correctly would be deeper than how it actually appears because the mode is 3D and the centre will be further away on the model too giving the right look.
Telephoto lenses do the opposite and make the fuse look too deep .

If you use photos, and sometimes you have to...you have to make lots of allowances or it will be wrong, very wrong.
