Moon
Is that an image of both Earth and Moon to scale?
Why yes, yes it is!
And it seems it’s a bit further than I thought…
Data and images of Earth and Moon are from Wikipedia.

Subliminal Tyler Durden
Been watching Fight Club and noticed a weird flash around 06:00. I thought it might have been a misplaced “Coming up next…” overlay, but when I scrubbed back, I was blown away. There it was, Tyler Durden, together with his shadow (which proves it was deliberate and carefully crafted), long before the character even appeared in the movie. (Later I found there are at least six such occurrences).
It’s actually funny (and self-referencing), as one of Tyler’s jobs in the movie is to do the exact same thing:
He flips the projectors, movie keeps going and the audience has no idea.
Why would anyone want this shit job?
Because it affords him interesting opportunities.
Like splicing a frame of pornography into family films.This is an allegedly powerful concept of sending subtle messages to the audience, too fast for the eye, but not for the brain. The use of such subliminal imagery in the movies is supposed to evoke strong emotions of fear — some even claim unexplained fear.
Although Wikipedia seems to question its effectiveness, there’s been quite some movies which use it, or at least claim they use it.
Regarding the most famous example, the Exorcist (1973), there’s some controversy whether the imagery inserted there was truly subliminal (and whether you’ve actually seen it or not: it was apparently removed and reintroduced in different editions).
But the most gruesome sequence I’ve ever (knowingly) seen (and deconstructed), was one of the final scenes of the Event Horizon. Strangely, I was unable to find any images from that movie, so I had to find a short clip and resort to mplayer1 to split it into frames. A selection of frames (viewer discretion is advised) is available here: Event Horizon subliminal pics. Some of the images are present for no more than a single frame, so there are many you’d have missed when watching the movie.
Does it work? Who knows. Some say it does, or at least hint it does (e.g., Malcolm Gladwell’s Blink: The power of thinking without thinking), others claim it’s nonsense. Either way, I don’t want anyone to feed me images like these without my knowledge. There’s a fantastic analogy I’ve read somewhere: If someone came to your home, entered your living room and emptied the trash on your carpet, you’d probably kick his ass. But when someone empties mental trash in the living room of your mind, you don’t even register. Unless you pay really close attention.

Hi,after years,when i gave look to those hellgiven photos , i’ve felt the same anguish,without having really seen theme,and just at the very beginning of the film i felt the same.It’s simply bad for me,to insert hiddenly,just to scare,seeding anguish,those images full of unuseless badness.Ok it?s a scifi horror,i didn’t know,but i received those…
I’ve found in(lost in the space)some subliminals,i’ve found theme in a panoramic view of the station,they are images of classic stlized aliens figures,just to make you think they are not human facilities!.Bye and thanks for your non-distraction -
liminal
if you want subliminal, check the movie Blade: in the very first scene of the very first movie, you’re shown people walking through a cold room with hanging meat, and while there’s nothing creepy in that scene, I felt really uncomfortable while watching it and suspected subliminal stuff. It took me some 30minutes until I managed to stop the video at the right 1/10 second to discover the subliminal image (which is the face of a guy with the throat cutted). You really cannot see it unless you stop the video at the right point, but your subconscious mind gets it. Clever.
Of course, this was almost 20years ago and audio-visual techniques have made outstanding progresses since then (through computer effects), and the flash images are no longer the way to go for subliminal stuff, instead they can now interlace two images, one on top of the other but you can only see the one on top. Subliminal sound is also possible (sounds or words hidden between a sentence), I’ve seen a few movies where they used that process (the sound effects in a speach get strange and while you hear a sentence you will feel strange about what was said as your subconscious mind heard something else). Last but not least, visual effects and sound effects are often combined to suggest something completely different from what is heard and seen. -

Hey, that’s a great find, I’ll check it out.
I do find all of this fascinating–especially how easily we can be subtly influenced, because the subconscious mind is always watching/listening. I’ve seen this video of a Derren Brown “trick” some time ago, and couldn’t decide if it was for real or a hoax:
https://www.youtube.com/watch?v=ZyQjr1YL0zgBut I read about a controlled experiment, the “two cord puzzle”. There the subjects were asked to tie together two pieces of rope, hanging from the ceiling (the pieces were to far apart to be reached at the same time). No one thought of swinging the ropes to make them come closer together, until the experimenter “accidentally” brushed against a rope, and that provided the necessary clue. But every subject in the experiment was convinced that *they* thought of that brilliant idea on their own.
Since then I believe that the video above is most likely real. And if that’s real, you can basically manipulate anyone just by feeding them subtle clues, and they’ll think it was their idea all along..

Movie Word Cloud
I’ve calculated the word frequency in the subtitles of about 40k English movies. I thought I’d get something useful, but can’t see it yet. Listing highest ranking words proved almost entirely useless, so I excluded the most common stop-words. Here I listed the highest 500 ranking words.
An interesting question here would be: is the relative frequency any different than the relative frequency in English language in general? What words have higher frequency in movies than in everyday language? Can we detect movie speak by the lack of certain words?
But what seems more promising than doing a simple word count is Yahoo term extractor which, surprisingly, does a pretty good job. For example, American Beauty yields these terms:
- lester burnham
- neighbor jim
- pruning shears
- product launch
- lover jim
- miracle gro
- typical teenager
- geek boy
- daughter jane
- wife carolyn
- eggshells
- role model
- high point
- clogs
- misery
- loser
- girlfriend
- honey
- roses
- dad
In fact it’s almost as good as watching the movie 🙂 . That’s why the next step will be listing the most common Yahoo-extracted terms for all the movies. Gotta do it while Yahoo’s still around 🙂 .
This bit of Ruby code queries Yahoo term extraction API (you need an API key first):
require 'net/http'
require 'rexml/document'
app_id = '***************'
yahoo_uri = URI.parse('http://api.search.yahoo.com/ContentAnalysisService/V1/termExtraction')
resp = Net::HTTP.post_form(yahoo_uri, { 'appid' => app_id, 'context' => text } )
terms = REXML::Document.new resp.body
terms.each_element("//Result") do |term|
puts term
end

Creating false-color IR images
What is false color?
With false color I’m referring to what Kodak EIR Ektachrome film does. This means, that the IR part of the spectrum is represented with red color, the red part of the spectrum is shown in green color and the green part in blue color.
This means that the mapping of channels changes from (red → red, green → green, blue → blue) to this:
IR → red
red → green
green → blue
blue → discarded
More information on how to shoot in IR.
What does it mean?
It means you have to take 2 images for every false-color shot.
One has to be in IR and the other one in visible light. They have to be perfectly aligned, so the camera shouldn’t move between shots. It’s best if you use a tripod.
Image in visible light
Image (same scene) in IR
Then what?
Next, you have to combine both shots in Photoshop (or some other program), replacing the channels like shown above.
Before that, I used Auto Levels to equalize the IR image;
Channels in Photoshop
Remapping channels
You have to start from the back though — first you have to select only GREEN channel, copy the “green part” of the image, select BLUE channel and paste “green part” into it.
Next, select RED channel, copy the image and paste it into GREEN channel.
Finally, select your IR image, copy it, then select only the RED channel of the visible light image and paste the IR image into it.
You should get something like this:

Shooting in IR in 5 easy steps
1. Select an appropriate camera
I used Canon PowerShot A80, when I incidentally discovered that its IR blocking filter passes quite some IR to the CCD.
Check if your camera “sees” IR with a TV remote control. It should look like this:
2. Get an IR-passing, visible-light-blocking filter
You can buy quite some of them (Cokin, Hoya), but I chose another way and made one myself from overexposed & developed film. I cut two tiny pieces from the end of some of my old filmstrips (there always is some overexposed slack at the end).
I used two layers of film (just to make it completely block visible light) and made an improvised IR-passing lens-cap for my camera.
Another test with the remote control showed that overexposed and developed film is virtually transparent for IR.
3. Get outside
Sun is probably the strongest IR illuminator you can afford. Sunlight decreases the exposure times and your pictures end up less grainy.
4. Take pictures
It needs some experimenting to get the optimal exposure and focusing. At least in my case, where my DIY filter probably blocked some parts of IR spectrum as well – the image on the LCD was very dark and I had to focus manually by feel.
5. Postprocess
All pictures have a strong violet tone, like this one:
With some postprocessing (Auto Levels in Photoshop), you can make it look like this:
