Light Painting (while pregnant) – Smarter Every Day 41


Hey it’s me Destin. Welcome to Smarter Every Day. So most women get pregnancy photos then a couple of months later look at them and say what the heck was I thinking, but I’ve decided to bring my wife here to a (wife) spooky abandoned warehouse.
Yeah it is a spooky abandoned warehouse. And, there’s a guy named Wes Whaley, and he is a light painter, one of the best ones I’ve ever seen. Anyway, he lives close to me so I contacted him and said hey can you do some pregnancy photos for me. Anyway, so today on Smarter Every Day we’re gonna teach you about light painting. Are you excited?
-yes. Behold the sexiest pregnancy photo ever made. [laughing] [music] OK so this is your camera shutter, and the camera shutter opens to reveal an image sensor. And this image sensor is made up of several pixels. Now any time photonic energy hits the image sensor the sensor converts this light energy into electrical energy. So we’re gonna illustrate that by blasting me with photons So can you blast me with some red photos?
Woo! Alright, there you go. Keep blasting away. So as she’s blasting, I’m gonna take these You got em in my shirt. This red and green photon energy and, go ahead, good job. I’m going to slowly deposit this yellow light, which is red and green mixed, into the top left corner here. So basically, all the energy that goes into the image sensor, as long as it gets there before I close the shutter, then that’s what your image is gonna look like. So you can see we have some red and blue, but up here we have yellow, which is a mixture of green and red. So, that’s how light painting works. You expose the sensor. You add light, as if it’s paint on a canvas, and then you close the shutter. Now, the one flaw in my metaphor here is, a real shutter doesn’t open like this. Last week with the Phantom high speed camera I showed you that the shutter opens from one side, and then it closes from the same side. The reason it does that is you want a uniform exposure on all the pixels. So, talk about the sensor now. So there’s two main types of image sensor. The first one is a charge coupled device or CCD. Now CCDs are uniform, and all they do is they take.. Are you done with the particle waveform analogy there? Can I have one? -That’s done.
Oh that’s a good one. This is blue? Alright, so light is a particle and a wave. So as the light comes in here and hits the sensor you get an output voltage. That’s how a CCD works. However, a CMOS sensor, which is a complimentary metal oxide semiconductor is a little bit more complicated. It has on-board circuitry that processes each individual pixel as it’s being exposed. So the problems with this is that you end up having a little bit more noise, and it’s a little bit more expensive to make these chips, however they’re getting really good at factoring all this stuff out. So CCDs are typically used for really low noise applications really low cost. CMOS chips are usually used in things that need to have a very tight form factor, so a lot of the stuff is done on the chip itself and you don’t have to have auxillary circuit boards. So as you look at the rest of Wes’s work here just think about this. As the sensor is exposed it doesn’t matter when the light gets there. If you have a 3 watt laser over here that blasts for a nanosecond it might be equivalent to a really low power LED dimly shining over here. That’s why you can light paint without actually showing up in the image. [music] If you want to learn more about Wes and what he does, just go to the video description down below, and click on the link going to his Flickr page. He’s got a lot of cool stuff on there and, I chose not to video some of the stuff he does, cause he’s a little mysterious and I don’t want to give up his secret sauce. But if you want to try to figure it out go check him out and contact him.
Get Smarter Every Day. Have a good one. Hey all the songs that have been used in Smarter Every Day videos so far are all together in one album. I’ll put the info in the video description.
Hear you. Go ahead. Catch a photon! If you can get a laser then tie LEDs to your dog and then you can shine a laser and make your dog chase the laser, and get a good image that way. There’s all kinds of good stuff you could do. [ Captions by Andrew Jackson ] Captioning in different languages welcome.
Please contact Destin if you can help.

  1. but Wikipedia says " Light with a wavelength of 570–590 nm is yellow, as is light with a suitable mixture of red and green.". so it is its own wavelength as well as red a green?

  2. I love light painting, thanks for sharing! I haven't done all that much with it yet but it's such a creative outlet!

  3. smarter every day… i wonder how smart his children are gonna end up being… they are exposed to this every day… literally

  4. Well, sort of. Your eyes can only see red, green, and blue, so when you see something "yellow", it's because the red and green cones (sensors) in your eyes are both responding. That could be because the light is actually yellow (such as from a rainbow or yellow light bulb), or because you're seeing a mixture of red and green (like from a TV or computer screen).

  5. Wait. Aren't the primary colours red, yellow and blue? That's at least the primary colours of a common colour chart. Is this just a mix up between art and science, because the eye can see red, green and blue, but somehow in art the primary colours are described as red, yellow and blue because of the colour circle? Because this is the first time I've ever heard someone (that's smart) say that green is a primary colour. And sorry if you get annoyed when I write colour, I use English UK and not US.

  6. Haha smart people just don't buy trollings. Well, I'm not that bright that's why I replied to your pathetic message. Well here's some tips from me, find some good friends, involve yourself in a positive society since you seems to have been breaking your mind with things like conspiracies and bad jokes. Youtube contains a lots of things and plenty of them are bad. Be smart and choose wisely.

  7. Your daughter is making "particle wave-form analogies"! She is going to be a genius! I didn't even know that light was both a particle and a wave until I was a junior in high school! 🙂

  8. 2:03 Kid becomes a completely normal child in front of a camera…
    2:16 Destin looks at daughter who is a perfect angel with a big smile.

    Love your kid, dude. She's awesome.

  9. Already did that. Search my channel for "Dragon's Breath". By the way, it won't work in a Saiga because it's gas operated.

  10. I didn't get it until the end when it showed the pictures, it just looked kinda boring until then, I mean the science was cool, but the application didn't pay out until later. it was worth it though.

  11. I hope Wes makes a couple million off his brilliant light paintings. Mesmerizing and original! Thanks Destin for the great vids.

  12. Look up Neon Light Tubes. That's what those are. They're the same tubes you would see at stores, like the "Open" sign.

  13. This is correct. primary colours in art are different to primary colours in light, whilst in printing applications its cyan, magenta and yellow.

  14. Hey great work! I just have a quick question for you. How would you create a light painting photograph with a subject in it, and keep that subject tact sharp without any blur? Is it possible? I know your shots show subjects in it but I don't want any blur from my subject. The only thing that makes sense to me is 1 of 2 ways: 1) Photoshop 2 separate exposure and make a composite. Although I feel that this may look fake. 2) use a ttl chord, (10m or longer) put the camera on 2nd curtain, paint the shot and the flash will freezing any blur. But with this I feel like the subject might get that ghosty faded effect.

    Let me know what you think!

  15. After watching several episodes (including the beat boxing one XD so funny) I'm totally excited to subscribe to you.

  16. The little girl has the voice of a adult i had to see if that was her talking lol. This is a great video though!!!!! I freaking love science

  17. This is awesome – I've never seen anything like this.  Thank you for putting this out there.  Growing up, science was not a favorite subject but you make it interesting and fun!  Thank you!!!

  18. Nice video man !!! You got a cute photon thrower girl !!!! Its nice to involve your whole family on your projects!!

  19. I wish this playlist was in reverse order so I could watch them all as they were chronologically released.

  20. that title though.

    I thought it will be about "I'm so wonderful I can take pictures while pregnant." Glad it was not.

  21. This was probably the most coolest and easy-to-understand way of breaking this down. it made perfect sense compared to the other videos I seen. Thanks for posting
