Popular Post ChrLzs Posted September 27, 2016 Popular Post #52 Share Posted September 27, 2016 Well spotted bmk - if ever there was a coffin nail, there it is.. And here it is with the 'gamma' (sorta like brightness only better..) wound right down and the contrast tweaked up to reveal the almost-hidden detail: Yes, the alienz are now so crafty that they not only disguise their ships as downlights, but even EXIT> signs. 10 Link to comment Share on other sites More sharing options...

I know you are good I know you are knowledgeable, but sometimes you makes it very hard to believe you really know that much with your level of defensiveness ... Quote Gamma correction *** Explanation Gamma encoding of images is used to optimize the usage of bits when encoding an image, or bandwidth used to transport an image, by taking advantage of the non-linear manner in which humans perceive light and color.[1] The human perception of brightness, under common illumination conditions (not pitch black nor blindingly bright), follows an approximate power function (note: no relation to the Gamma function), with greater sensitivity to relative differences between darker tones than between lighter ones, consistent with the Stevens' power law for brightness perception. If images are not gamma-encoded, they allocate too many bits or too much bandwidth to highlights that humans cannot differentiate, and too few bits or too little bandwidth to shadow values that humans are sensitive to and would require more bits/bandwidth to maintain the same visual quality.[1][2] Gamma encoding of floating-point images is not required (and may be counterproductive), because the floating-point format already provides a piecewise linear approximation of a logarithmic curve.[3] Although gamma encoding was developed originally to compensate for the input–output characteristic of cathode ray tube (CRT) displays, that is not its main purpose or advantage in modern systems. In CRT displays, the light intensity varies nonlinearly with the electron-gun voltage. Altering the input signal by gamma compression can cancel this nonlinearity, such that the output picture has the intended luminance. However, the gamma characteristics of the display device do not play a factor in the gamma encoding of images and video—they need gamma encoding to maximize the visual quality of the signal, regardless of the gamma characteristics of the display device.[1][2] The similarity of CRT physics to the inverse of gamma encoding needed for video transmission was a combination of luck and engineering, which simplified the electronics in early television sets.[4] wiki link ~ Link to comment Share on other sites More sharing options...

ChrLzs Posted September 27, 2016 #55 Share Posted September 27, 2016 Let me be CLEAR, CONCISE and BRIEF, Third Eye (you should try it sometime rather than posting text and pretending it is relevant and that you understand). First up, IF you think your version of the EXIT sign is more clear than the gamma/contrast adjusted one I posted, then that just goes to reinforce what I said about badly adjusted, low quality screens.... 3 hours ago, third_eye said: Apologies accepted ... I gave NO apology for CORRECTING your false statement that you deliberately avoided and edited out of your reply. May I remind you that YOU said this: Quote the negative of the image will show clearly if its a light source or a reflected light source Do you DENY you said that? Just answer yes or no.

ChrLzs Posted September 27, 2016 #57 Share Posted September 27, 2016 (edited) To be complete.... one of the characteristics of double-glazed windows is that the displacement of the secondary 'doubled' image is pretty much entirely dependent on the angle thru which you are looking at/thru the glass. For the areas straight on and directly at right angles to the glazing, you will see no displacement. If you look to the left or right at an oblique angle, the doubling will be horizontal, and the more the angle (ie the more towards to edge of the image), the more displacement you will see. As you look up or down, then there is an added vertical component to the displacement. That's what I meant when I referred to the displacement angle of the two reflections of the lights - the upper left one near the building shows a different angle to the one over to the right, and the angles are as one would expect. It occurred to me that the reversed EXIT> sign, given that the camera was pointed upwards, was probably about in the right place to be seeing the two panes at about square-on vertically. In other words, one would expect any doubling of THAT bit of image to be close to horizontal only... So I went to the original image that was sent to me, and did the same trick, ie adjusting gamma and contrast, and hey presto - the displacement is EXACTLY as it should be - pretty much horizontal only. Here you go, look carefully to the left of the reversed > symbol and you will see the second reflection: So all three reflections are exactly consistent with the double-glazed window theory, and we have two overhead downlights and one EXIT> sign. It can't be more cut and dried. Edited September 27, 2016 by ChrLzs 7 Link to comment Share on other sites More sharing options...

Yeah, that makes sense. You think this thread was started in order to "bait and trap" someone? Who would do that and for what possible reason and who would they be trying to "trap"? The OP didn't even post the pic as he couldn't upload the image as it was too big to attach to his post. It took one of the UM regulars (Hudds) to find the image on the OP's Twitter account and hotlink it here. If it was a "bait and trap", it was subtly done. Seriously, this is just paranoid rambling. When you find yourself in a hole, stop digging. Edited September 27, 2016 by JesseCuster 4 Link to comment Share on other sites More sharing options...

I'm not sure how many members actually been to OP's Twitter account?. Well, I obviously have and found it almost full of holiday and other advertising/ deals links etc. I actually didn't pay too much attention to the tweets at the time, as I thought this guy most probably may have captured something interesting during his holiday trip. And to avoid other members going to his Twitter account, I uploaded the image on here, instead. Come to think of it now, after this thread has been debunked. Was it an attempt of bait and trap?, there is possibility. Edited September 27, 2016 by Hudds Link to comment Share on other sites More sharing options...

These things look like flat, silver hot air balloons, but have some exhaust residue Although the "EXIT" symbols are a worry.

ChrLzs Posted October 4, 2016 #69 Share Posted October 4, 2016 Exhaust residue???? You may be handy with Photoshop, but I'd love to see the logic that drove you to think that a little spilled light was 'exhaust residue'. And the exit sign isn't a 'worry', it's an absolute nail in the coffin and definitively proves he was behind glass and therefore told us a lie, even if it was just a misremembering.. They are downlights reflecting in glass, end of story - you can even go find images within that hotel showing the ceiling lighting.. 5 Link to comment Share on other sites More sharing options...
