Dave Greer Posted September 16, 2010 Share Posted September 16, 2010 I'm curious about whether the lens dust brush caused an opposite clectrostatic charge to that of the dust. Or was the dusting neutral? Don't know the answer to that one John, maybe someone else can help out. Link to comment Share on other sites More sharing options...
Guest James H. Fetzer Posted September 16, 2010 Share Posted September 16, 2010 Part I: Jack White's Apollo Photo Studies Argument 3: The Anomalous Visor Reflections Many photos of astronauts alleged to have been taken on the moon have anomalous reflections in the visors of astronauts' helmets, some of which offer indications of photo fakery. Jack and I are in the process of reviewing those most illuminating in relation to their importance as proof of fraud. Link to comment Share on other sites More sharing options...
Jack White Posted September 16, 2010 Share Posted September 16, 2010 Here is such an example. The photograph has a mottled appearance (red arrow) where the unretouched area exists. But WHERE THE SOLID BLUE UNMOTTLED AREA APPEARS, IT CLEARLY IS RETOUCHED...because the blue area shows NO MOTTLING. Before people comment on such things, they should know what they are talking about. Jack PS...the first image is the correct one. I posted the other one without saving a change, and cannot figure how to delete it. Jack I'm not sure what you proved here, other than the sky was blacked out of this version of the image to remove scanner noise? Are you saying that I have proved that the photo has the sky blacked out and therefore is not genuine? Why was the SKY blacked out because of "scanner noise" when scanner noise IS NOT PRESENT IN THE REST OF THE PHOTO? What does the fake black sky hide? Other black areas of the photo are not blacked in. WHY IS ONLY THE SKY BLACKED IN? By conceding the sky has been blacked in, you are admitting the photo is NOT GENUINE!

Jack White Posted September 16, 2010 Share Posted September 16, 2010 (edited) If "dust on the lens" were really causing this photographic anomaly, then that same "dust" would be evident on more than just this one ( or possibly a few other) photo .. There are many similar examples across the Apollo surface photography. I showed you 5 in this one pan. Since dust (whether lunar or simulated by NASA ) seemed to be covering everything, then all of the Apollo photos would show the "dust on the lens" problem, instead of just this one, or posibly a few others, where this particular anomaly has occured. Only if the lenses were always coated in dust throughout the entire duration of each EVA. They cleaned the cameras at the end of each EVA, and also had a brush for dusting lenses during EVAs (there is video footage on the ALSJ of them dusting the TV lens, for example). SCOTT: I think the camera would be better off if we’d protect it a little bit better. We used the lens brush on the cameras, and they were very good. IRWIN: On the TV also. SCOTT: On the TV also. The lens brush is really a good brush. It cleaned it off very well. The dust brush, to clean off the suits seemed to work pretty good. It got the gross dirt off. It didn’t get everything. I guess it also worked quite well on the LRV and the LCRU mirrors – cleaned them off pretty well. Source That's why your typical Apollogists excuses of "dust on the lens", or "compression artifacts", or "pixel size", or "cropped images" or "smudges on the visors" are nothing but lame attempts to explain away the MULTITUDE of ANOMALIES found in the official Apollo photographic record. Cheers You may call them lame attempts, but you can't offer any evidence why those explanations are false. If Jack hadn't posted his latest study, you'd still be thinking the scanner noise was stars, and accusing everyone else of offering "lame excuses". Please show us examples of SCANNER NOISE in good parts of the photo. Why is there not scanner noise over the entire photo instead of just the sky? Please show us examples of LENS DUST which ruins good parts of the photo, not just the sky. Why is the dust so selective that it needs retouching in the sky, but not the rest of the photo? Lens dust and scanner noise are LAME EXCUSES, not shown by ANY studies. Jack Edited September 16, 2010 by Jack White Link to comment Share on other sites More sharing options...

Dave Greer Posted September 16, 2010 Share Posted September 16, 2010 Are you saying that I have proved that the photo has the sky blacked out and therefore is not genuine? No. Proving the sky was blacked out does not mean that the ORIGINAL image was not genuine, and that is all that we're interested in: the ORIGINAL images. Why was the SKY blacked out because of "scanner noise" when scanner noise IS NOT PRESENT IN THE REST OF THE PHOTO? What doesthe fake black sky hide? Other black areas of the photo are not blacked in. WHY IS ONLY THE SKY BLACKED IN? Scanner noise tends to be more apparent in large areas of black, as you showed in your study of AS15-85-11425. Blacking the sky hides scanner noise which is present in most scans of images to a greater or lesser degree. You can see it in every high-res scan of Apollo images available on the Gateway to Astronaut Photograph website - the images are taken from scans of the actual films rolls, and haven't had any processing applied to them. Check out this website that discusses scanner noise. Such artefacts become an inseparable part of the image in all scans. With regular daylight material these artefacts should never normally become visible, however they have potential to become visible when stretching contrast and doing other enhancement work to thin astro negatives. The more that an image needs to be enhanced, the more that scanner artefacts become visible. By conceding the sky has been blacked in, you are admitting the photo is NOT GENUINE!Jack I'm doing no such thing, please don't put words into my mouth.

Duane Daman Posted September 17, 2010 Share Posted September 17, 2010 "Amazing! Duane, why can't you just admit you made a mistake? We've all made errors in the past, and to be able to admit when one is in error is a sign of character." No worries mate .. I have no problem admitting when I'm wrong.. I got that lens info completely backwards. My dyslexia often prevents me from reading certain information correctly, especially when the print is small and I'm rushed for time.

Evan Burton Posted September 17, 2010 Author Share Posted September 17, 2010 No problems Duane; dyslexia can really make life difficult for you. Lesson learnt though - when people dispute your work, recheck your claims... slowly and carefully. Even then, you are probably going to miss something if it involves a large amount of text. One of my responsibilities is for a large manual that details procedures for aircraft operating with ships. Despite have done a major review of it over the last couple of years, and having three seperate people proof read and accuracy check, I am still finding spelling or syntax errors, etc, that have been in the publication for many years!

Evan Burton Posted September 19, 2010 Author Share Posted September 19, 2010 I look forward to seeing them. In the interest of the non-Apollo experts, could we please have image numbers this time?

The following site seems to have pointers to an answer, but I'm not anything but snaphappy with some sense of issues to consider and concepts, terminology are largely beyond me. So I'm posting this to log the info in the hope that some day I'll understand the whole thing. (The gif is quite interesting) http://en.wikipedia....8photography%29 ''In photography and cinematography, perspective distortion is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal focal length, due to the relative scale of nearby and distant features. Perspective distortion is determined by the relative distances at which the image is captured and viewed, and is due to the angle of view of the image (as captured) being either wider or narrower than the angle of view at which the image is viewed, hence the apparent relative distances differing from what is expected. Perspective distortion takes two forms: extension distortion (?) and compression distortion, also called wide-angle distortion and telephoto distortion, due to these corresponding to capturing a given field size with a wide-angle lens (hence from closer than with a normal lens) or capturing a given field size with a telephoto lens (hence from further than with a normal lens) – and in both cases then viewing from a normal distance. In extension distortion, which can be seen in images shot from close using a wide angle of view, an object close to the lens appears abnormally large relative to more distant objects, and distant objects appear abnormally small and hence more distant – distances are extended. In compression distortion, which can be seen in distant shots with a narrow angle of view, distant objects look approximately the same size – closer objects are abnormally small, and more distant objects are abnormally large, and hence the viewer cannot discern relative distances between distant objects – distances are compressed. Note that perspective distortion is caused by distance, not by the lens (?) per se – two shots of the same scene from the same distance will exhibit identical perspective distortion, regardless of lens used. However, since wide-angle lenses have a wider field of view, they are generally used from closer, while telephoto lenses have a narrower field of view and are generally used from further away. For example, if standing at a distance so that a normal lens captures someone's face, a shot with a wide-angle lens or telephoto lens from the same distance will have exactly the same perspective on the face, though the wide-angle lens may fit the entire body into the shot, while the telephoto lens captures only the nose. However, crops of these three images with the same coverage will yield the same perspective distortion – the nose will look the same in all three. Conversely, if all three lenses are used from distances such that the face fills the field, the wide-angle will be used from closer, making the nose relatively larger, and the telephoto will be used from further, making the nose relatively smaller. Outside of photography, expansion distortion is most familiar in side-view mirrors (see "objects in mirror are closer than they appear") and peepholes, though these often use a fisheye lens, exhibiting different distortion. Compression distortion is most familiar in looking through binoculars or telescopes, as in telescopic sights.'' (?) adds edit formatting More of the same, here from the ''theatre of noise'' http://www.theatreof...r-size-and.html ''Perspective distortion is only influenced by how far you are from your subject. It has nothing directly to do with the lens or camera. It has nothing to do with the focal length and nothing to do with the size of the sensor or film you are using. However, if you are using a wide-angle lens you will need to be closer to fill the frame with your subject. This will lead to extension distortion, which is why it is also commonly called wide-angle distortion. And likewise you need to stand back when using a telephoto lens, so you will be able to capture more than a nostril. And this leads to compression distortion, AKA telephoto distortion.'' edit formatting Link to comment Share on other sites More sharing options...
