I know I'll be attacked for saying so, but I have never seen the
slightest indication from the material I have see that Dilettoso
knows anything about photo or video analysis.

Someone recently sent me a photo which Dilettoso and co. had
"analyzed".  On it was a small "UFO" over a lake.  Dilettoso had
told the owner of the photo that it was lens flare after doing
his snake oil show computer stuff.  I took the negative into my
darkroom, ran the enlarger all the way up, and made a print.  The
"UFO" was very clearly a bird!!!  It did not require any computer
equipment or any other fancy gear to do a real analysis in this

With the exception of Bruce Maccabee and a very few others, I
have been uniformly disgusted with the so-called photographic
analysts paraded around the UFO field.  They show only a
rudimentary technical knowledge of photography and video, if they
show any at all.
