Being someone who does CG stuff myself. I can say that those photos on that site are indeed CG. Of course their are ones that are obviously CG, but
i'm referring to the ones that are superimposed over actual photos. I didn't read every single post, so forgive me if i start to explain things that
have already been covered.
Ok lets start with the very first photo:
Firstly the thing that stands out to me is the shadow. It is very sharp not to mention the actual aircraft itself just seems a bit too sharp and clean
around the edges. The shadows also have no variance. Shadows arn't generaly just one solid shade either. Reflected light from some parts of the
aircraft should affect areas of the shadow as well as ambient blue light from the sky should also affect parts of it as well. Not to mention around
the base of the wheels should be slightly darker since the black tires would reflect no light.
The reflectivity of the surface of the craft is just to crisp as well. The surface is too smooth. If you look up close on an aircraft it's usualy a
little bumpy. Not only with just the rivets, but the skin of the aircraft usualy has some subtle bumps as well. Here is what a reflection should
generaly look like of an aircraft with just plain aluminium skin:
note that the reflections are not sharp. They are fairly distorted and the surface isn't that smooth.
Now onto another photo. Lets take a look at this one:
Ok the first thing that sticks out to me is that blue colour used for the american symbol on the wing. That blue is just too saturated. Maybe it's
just me, but i believe a darker and less saturated blue was used.
I believe some one else already pointed this out. The saber there in that pic really doesn't look right at all. One thing that really gives it away
is the tail. Note how the horizontal stabilizers by the tail don't taper inward towards the ends in the aparent photo, while they do in the actual
photo post above it.
Now if you scroll down further on page 2 you'll come across this image:
No doubt that this is CG. and you will see another photo below that one where it is placed into a photo (and not very well done mind you). You can see
clearly that it's the same aircraft in both images, and also that it was used in the same image taking off with the saucer. If that doesn't prove
it's CG i don't know what would.
The guy did a decent job, but not nearly good enough to be completely believable. The B&W photos turned out better, but they would be easier to do. I
think this pretty much renders (no pun intended) the site a hoax.
