Gulf of Oman, near Iran - 1978 or 1979, 11:00 P.M. to 2:30 A.M.
The crew of the U.S.S. Nimitz spotted a glowing object about 1500 yards to starboard. It was a cigar-shaped UFO with two portholes just above the water's surface. Photography was attempted, and failed. The object was not picked up on ship's radar. Several members watched the object for several hours through binoculars. Commanding officers informed those who witnessed the object that they were not to talk about it.

According to some research, some UFO's are only visible in the infrared spectrum and can be photographed by an IR camera.
Although I've mostly been interested in sensory augmentation by means of technology, there was an interesting third-hand report of augmentation through diet and biochemistry. The military during WWII (there are mentions of both US and British forces) evidently experimented with putting people on diets that replaced the normal form of vitamin A with a slightly different chemical, in the hopes that the red-sensitive photopigment in the retina constructed from it would be changed to a chemically similar form, present in other animals, with spectral sensitivity extending into the near infrared. The idea, of course, was to be able to see signal lights and so forth that were invisible to enemy soldiers.
I did some quick checking on this, and though I couldn't find any references to military research, there were some examples in the regular civilian literature. Yoshikami, Pearlman, and Crescitelli (Vision Research 9:633-646 1969) did a similar experiment on rats, putting them on a diet which was deficient in vitamin A and supplementing it with additions of either vitamin A1 (the normal form) or A2 (the altered one). No behavioral studies were done, but they did extract the retinas and perform some spectral analysis, with the result that there was indeed some alteration of the photopigments, specifically the addition of a second form with sensitivity shifted redward by about 20nm.
That study cited Millard and McCann (Journal of Applied Physiology 1:807-810 1949) which was an experiment on humans, albeit with fairly loose controls on diet. They found that behaviorally the group taking A2 supplements had slightly improved red sensitivity, but didn't provide any detailed spectral response curves.
So it seems to be the case that this effect is real, but small: the best you can hope for is a shift of about 20nm, which is not really enough to be of military significance or even detectable without careful testing. Still, it's an interesting "hack" on human biochemistry.

A number of years ago, a friend of mine was at an multiple day outdoor concert and observed some clowns (literal clowns, not just people acting stupid) who were waving oddly at him and didn't look right.
Pulling out his disposable camera, he spent the afternoon stalking around them, taking pictures from different areas, exhausting the entire roll of film. All while they quietly watched him, occasionally dancing.
After getting home a couple days later, he eagerly brought in the camera to walmart, and after an hour anxiously opened the package of developed pictures. He needed other people to see these clowns.
Turns out the clowns were actually garbage bins. He had spent the morning before seeing them eating mushrooms, but in his bewildered excitement, had forgot to factor that in.
My point? Sometimes you should know better than to expect magic clowns show up on film.

This is kind of related. I woke up one morning in Helsinki, we lived on the 5th floor and was looking over the terrace outside. To cut a long story short I took a photo from about 70 meters away - I could visually make out a metallic sphere, just larger than a football (soccer ball for our cousins) with a horizontal strip/e around the middle and making some very audacious manoeuvres - tripped me right out - my wife also saw it as it sped off.
I got a few pics with an old 5mgp camera and all that came out was a yellow/gold blob and then a black one at distance - nothing like what I was seeing.
To get to my point they may have some sort of 'security' against photography - I mean if we can spray our number plates to avoid the speedcams imagine what can be done.
I have one pic in my media I think but couldn’t upload back then - if anyone’s curious I will dig it from the old h/d and post it.

No, it isn't possible.
If you think about it, if a physical object only reflected or ommited light beyond that detectable by a camera, it would still block out the light from behind it. So you would still 'see' a silhouette.

As for for the U.S. Nimitz's attempt at a UFO photograph --- I would not be surprised at all.... if somebody sabotaged the negatives on the roll of film, before it ever had a chance of being developed; though 1,500 yards is a very long distance.
