Killian's photographic exploration: the reasons for the color change of photos

It's like an interesting detective story. When shooting with color film, the color of the image in Killian is usually between blue and blue-white-the specific color depends on the film model. However, sometimes orange, red and yellow appear in photos. Some surprising concrete explanations have been put forward. According to the suggestions made by Boyle and Tiller of Stanford University and Puke of the Graduate School of the US Department of the Navy, researchers at Seymour University in Delecque pointed out that the appearance of orange may be due to the use of a photosensitive film based on transparent film. If the film base is opaque, this will not happen. When the test object has high moisture content, the color may also shift to the orange-yellow area.

Further research found that the color film was coated with blue, green and red dyes from top to bottom. In general, the light of a certain color will only be absorbed by the corresponding dye layer, that is, the radiation with higher energy (blue light) will be absorbed by the blue dye in the upper layer, and other components with lower energy will be absorbed by the two dyes in the lower layer respectively. As long as the exposure is not excessive, the image will show the original color of the subject. However, when shooting in killian, the subject is in direct contact with the film. This is a special shooting condition. Researchers at the University of Seine in Delecque found that if the water contained in the test object permeates the film, the corona glow will not only appear in the place where there is water vapor, but also appear under it. That is to say, corona glow will appear on the back of the film. If the film base is transparent, the red dye layer at the bottom of the film will be affected by any incident light. No matter what kind of light comes, the image produced on the film is orange-red. Therefore, this discovery, which has been mysteriously and vaguely explained in the research data of special phenomena, is once again proved to be caused by simple physical reasons.

The research on killian effect continues. We found that this is a rather complicated phenomenon. For the practitioners of "psychic healing" seen in the photos, the changes in the gas field before and after the operation should not be rashly attributed to some supernatural reason. We now know that at least 25 factors affect the imaging situation. All these physical variables must be understood and controlled one by one to understand the killian effect. For another example, this group of researchers from the University of Seine, Delecque, have repeatedly found that the range of the light cluster-that is, the light band that spreads outward from the fingertips of the camera-is also affected by the following factors: the model of the photosensitive film; Whether alternating current or direct current passes through the circuit; Voltage, electric pulse frequency, pulse rise time, line resistance insulator thickness; Water vapor content in the air; Shoot the geometric shape of the surface of the object; Wait a minute.
