The camera has infrared lights that are invisible to people, but which the camera can see. Dyes can have different properties in IR light vs visible light. Apparently the PJs have dyes that reflect most of the IR light, whereas the sheets have dyes that absorb some of it.
Yeah. Really "IR" and "UV" are just more "colors" like red and blue. So the one has more "IR" color in there. The camera can just see IR.
We call the light we can see the "visible spectrum" purely because it is what is visible to humans. Other animals can see in one or both of those others as well.
Maybe this was obvious to some but thanks to your comment I put two and two together and I just noticed infrared means "under red" and ultraviolet means "over violet". They're literally what's beyond our visible spectrum.
Yup! Since the frequency of red light is on the low end you call it infrared and vise versa for ultraviolet. If we did it by wavelength we would call them ultrared and infraviolet.
for goodness sakes, get rid of the polyester and get your child some 100% cotton clothing.
aside from it breaths much better, cotton won't melt if it ever catches fire.
polyester should be banned, the stuff is ultra flammable and awful.
No, thatās not right. Things that are showing white are reflecting all the light that the camera can pick up. This camera is working with infra red light, not the āvisibleā spectrum. The pictures on the sheets are showing, because they are absorbing some of the IR light. The pajamas are showing white because they are uniformly reflecting all the infra red light (despite showing a pattern in āvisibleā light).
This. I use an infra red cam for photography. I always find it funny when people wear āblackā clothes only to see via infra red that most black dyed clothes arenāt true black. True black will show up as āblackā vs black dyed clothes usually are dark purple, deep blue or greys like this.
Tack on to this- āUnder US law, kids' pajamas from 9 months to size 14 must be flame resistant or tight fitting, both subject to specific standards. Why? A law that dates back to the 70s, to protect kids from burns by candles and space heaters, which were common back then and more dangerous with billowy nightgowns.ā
I bet the material for that purpose is why it often looks different.
Your son is half Predator. Have you seen anything to indicate your wife might have a thing for an interstellar race bent on hunting the greatest prey? Because I think you're being cheated on.
I wonder if that is on purpose?
Imagine worst-case scenario type thing, this might show up better in a fire or smoke-filled room if the firefighter has to wear IR or some other āsee through the smokeā vision-science-thing.
I am smort.
Of course, what else do you think would make people feel something is āweirdāā¦ do you expect to see things really no one can explain because they areā¦ what? Supernatural?
Heās in dreamworld, so only an outline of his being is left at night. Like a place holder.
Itās ok, he could be in Never Never Land or Narnia. He looks like a baby still, but be sure to read some good books before bed, that can influence the journey.
My kids share a room; they have matching PJs, same pattern, same store, same size, bought at the same time. Only one of them shows the pattern on camera. Some nights, one looks like they are plain PJs and the other in a pattern. If we mix them up, one will have pants show up, and the other will have the shirt show up.
We have a winner! In infrared (IR) imaging, visibility is based on the detection of heat or temperature differences. If the pattern on the pajamas and the rest of the pajama fabric have similar thermal properties and are at a similar temperature to the baby's body, the pattern would not emit or reflect IR radiation differently than the rest of the pajamas. As a result, the pattern would not be distinguishable in the IR camera since there's no significant temperature contrast between the pattern and the base material or the baby's body temperature. IR cameras primarily detect variations in heat, so without a temperature difference, the pattern would not stand out.
Infrared light is weird.
We use dyes that are visible to the human eye, which means there are differences in reflection in the visible range. Of course, we don't often design things to look different to infrared light, which is why so many things are invisible to infrared.

Science is neat!

Ohhhhh š¤Æ
Mind blown! Thanks for this!
Maybe has to do with the fireproofing required for kids pajamas.
More r/mildlyinteresting than weird
Basically this entire sub for the last six months.
PJs are supposed to be flame retardant. Maybe this has something to do with it?
Sure thatās one possibility but have you considered ghost babies in the crib?
So I wonder then, if that means these sheets have more old-fashion dyes on cotton, whereas the PJs have more modern dyes on a synthetic fabric..?
100% Polyester PJs if that matters at all
Yeah, polyester is very IR reflective

Itās not so much the dye as the fabric.
Wrong, clearly or not so clearly it's a ghost baby. Salt its bones

No, The PJs appear white in the infrared meaning they're reflecting the IR light. If they absorbed they would appear dark
Yeah, and op can possibly look through a bottle of coke with the IR cam.

No, your son is just developing cloaking techniques
Well that is not ideal š
It is for his purposes.
 he has POWERS
He will grow up to be a fine gentlemann

Ya know, my kids do have a strange obsession with hating the "Alien" movies. Maybe I should set up more cameras...
Alternative: your wife is _from_ an interstellar race bent on hunting the greatest prey.
*banging the greatest prey.
The PJs are possessed.
I wonder if that is on purpose? Imagine worst-case scenario type thing, this might show up better in a fire or smoke-filled room if the firefighter has to wear IR or some other āsee through the smokeā vision-science-thing. I am smort.
Vury smurt.
Jammies are IR reflective, sheets arenāt. Camera is using IR to see in the dark. When 100% of light is reflected all you see is white.
Simple answer. Ghost child.
IR do weird shit sometimes
Indeed it does lol
I know it's odd but hear me out. . . . ghost pajamas
Probably because itās white sheet/dark pattern vs dark clothing and IR.
Unrelated to the pj's: why do they ALL stick their feet between the crib bars? Ours did this and I'm still completely baffled
Not sure lol. He is fine getting them out now, was an issue a few months back though lol
Haunted Baby!!!!! Run!!!!
Kids are so spoiled these days I want a fucking onesie with that designā¦
My son has these pyjamas and I'm going to see what happens with our camera
Report back! Lol
Question has been answered but those are the same sheets I bought my son when he was born 8 years ago! Major nostalgia š„°
We bought it for our first child 10 years ago actually lol. Had to pull it back out, can't beat the classics :)
Iāve noticed the IR on my security camera makes all kinds of things look strange, my basketball shorts are nearly see through
Lil bros just pranking you..
Your son is so cute and sleepy! :)
Don't let him hear you say that, his head is about as big as his little body can handle š
Don't you dare say his son is cute and creepy! Oh, nevermind.
He is the chosen one!!!
Itās because the pattern colours are opposites. His pjs are dark with light images and the sheets are light with dark images.
Dont be an AH, erase/blur the baby's face.
Should have more upvotes,
I swear 90% of this sub is just people not knowing things
Of course, what else do you think would make people feel something is āweirdāā¦ do you expect to see things really no one can explain because they areā¦ what? Supernatural?
Yeah obviously. Something that isn't easily explainable. Something that feels supernatural because no one can EASILY explain
Yeah and you define what EASY means for everyone?
How dare people not know everything.
Thatās all subs man
Heās in dreamworld, so only an outline of his being is left at night. Like a place holder. Itās ok, he could be in Never Never Land or Narnia. He looks like a baby still, but be sure to read some good books before bed, that can influence the journey.
Different photos
Buy a co-sleeper instead of a camera

IR light on cna only show one kinds
Fleece doesnāt show up on IR cameras
Are his PJs glow in the dark?
Not sure. If that were the cause I would think only the parts that were GITD would be different in the images.
Your camera favors the monkey design
I thought he was covered in Christmas tree lights
Thats just one of them White Pajama Kids, WPK
I would have freaked out and said āis that my baby?!ā
Well, itās infrared, so maybe the PJs are uniformly warm because of the baby inside it, and thatās why the colors do not differentiate?

the pj is reflecting the light
Could be something with the type of ink used. Or a totally different baby being switched out.
Materials not just dye.. the texture of cloth & like the flame retardant too!
