More Fake Pictures of Oswald

[Jack Trojan]

Hi Jerry, yes of course you are right and the original head ratios are indeed different. The wide-angle effect makes Oswald's head in 133-A stretch vertically as compared to the more centered head in 133-B thus exposing Trojan's gif. Btw imo this alone makes any image manipulation virtually impossible because not only do you have to match Oswald's lighting you have to match his position within the frame to allow for the appropriate image distortion.

Wrong again. These photos were supposedly taken from the same approx. distance from the camera so they should have similar distortion. There should also be less spherical aberration near the center of the lens (the sweet spot). I don't see ANY SA in CE133-A. That 35mm Cuera 2 camera must have had a decent lens on it.

You also don't write code I see. RGB1 is photo 1 and RGB2 is photo 2. A color is interpolated between 2 corresponding pixels according to the frame number (fn). Say you want 12 intermediary frames for your fade. Divide (RGB1 - RGB2) / 12 then multiply this increment by the frame number and add it to RGB1. This is the pixel color for your fade frame. Get it?

Yeah like I said your gif just swapped one set of RGB values for another, so what?

Which is exactly what your gifs do. Oh, you thought your gifs somehow tracked the facial features like facial recognition does, didn't you?

Yawn! I really don't know where to start, you are so out of your depth it ain't funny.

(507)  Additionally, photographs were made of a manikin head with an Imperial Deluxe Reflex duo lens camera similar to the Oswald camera, placing the image of the head in various positions from the center of the negative to the edges. The purpose of this was to illustrate the effect such variations in placement have on the shape of the image of the head in order to explain the differences in head shapes in photographs CE-133A, CE-133B, and, CE-133C, observed when the high-contrast color transparencies were superimposed. A black and white contact print of three negatives (fig. RIT 21-8) shows the  manikin head in the center of the photograph, near the top (tilting the camera down), and near the top left corner (tilting the camera down and aiming it, to the right). Placing the image of the head off the lens axis causes it to be elongated in a direction radiating away from the center of the photograph. Thus, the head at the top of the photograph is stretched vertically and the head in the corner is stretched diagonally. This change in shape can be seen on the contact print but the heads were also enlarged on high-contrast film and contact color transparencies were made so that direct comparisons could be made by superposing green and magenta pairs of the three images. (fig. RIT 21-9).

(508)  This change in shape is known as the wide-angle effect and it occurs with all conventional camera lenses including normal, wideangle, and telephoto, but it is most obvious with short focal length wide-angle lenses. In addition, pincushion distortion, which is evident in the curved reproduction of straight subject lines, and the altered perspective, which is evident in the convergence of vertical subject lines when the camera is tilted, slightly affect the shape of the head. (The differences in sharpness of the images of the manikin head when placed in the center and near the edges of the photograph is further evidence of curvature of field observed in photographs made with the Oswald camera.) Thus, the difference in height to width proportions of the heads in CE-133A, CE-133B, and CE-133C can be explained in terms of these effects since the tilt of the camera changed between the photographs, thereby placing the head in different positions. Of the three effects mentioned, the wide-angle effect, has the greatest influence on the shape of the head. Since the wide-angle effect applies only to three-dimensional objects, it would not alter the shape of the two-dimensional head on a photographic poster or print, which has been suggested as a way off faking the photographs of Oswald. Thus, the presence of this effect in the backyard picture is another item of evidence negating the likelihood of fakery.
