I agree that what you say is generally true except that an expensive lenses and manipulative software are not required to get good, reasonably accurate shots of airframe shapes and details. The primary requirement is that the photographer properly position themselves for the shot of the subject, with the awareness that likely no photograph will be absolutely 100% but certainly can be accurate enough for scale modeling purposes, being that no model is an absolutely 100% depiction of the real thing. In the case of these photos, while they aren’t absolutely perfect for the subject at hand, they’re close enough to demonstrate the generally smooth aerodynamic – not abrupt – lines of the bulge.
I stand by my original statement that no manufacturer has yet to accurately portray the shapes of the Bf 109E underwing cannon bulge, although I’ll add that most kits I’m aware of have fairly good approximations, just without the subtle (inverted) bell curve shape. Presently I’m working (off-and-on) at reshaping Tamiya items to add to planned future Wingsy Kits builds (will be making a mold for resin copies for the multiple I intend to build).
I’ve added three more photos for reference. The photo of the crashed aircraft is useful in its display of the contours of the access door aft panel line, which definitely shows the bell curve shape.
And to be sure, my bringing-up this issue of a minor shape problem with the current crop of Bf 109E kits is by no means intended as a can’t-be-built slam against any of them. I’m just pointing-out a perennially over-looked detail item.
Best regards to all,
Mike
