How the heck is a comment older that it’s video
Glass doesn't let 100 percent of light pass through. It reflects 4 percent back on each side of the pane. So, in total, you'll only get 92 percent of the light passing through. Technically speaking, glass does cast a very faint shadow.
Yeah that's what I thought too, like, a very faint shadow.
I mean in theory yes, but that doesn't account for the thickness of the glass and a lot of physics calculations do simplify things. And I'm staring at a couple of breakers right now and they have about 25-50% of the shadow of the Clorox wipes next to them. And the edge shadows are pretty visible and behave in mostly the way she described (there's extra shadow where the water line is in my beaker).
lost shadows?
THANK YOU!
@@icephoenix174 I was talking about window panes, not glasses or beakers of water.
finally someone transparent about how to draw glass!!
lol I love this
😂😂😂
She sheer fact that light reflects off of glass, is proof that it casts a shadow.
When light reflects off a window, then a certain amount of photons are not passing through.
If you would place a clear standing 'window' somewhere in sunlight, meaning, without a frame around it, you will very clearly see where the shadow is. Otherwise it would simply be invisible.
When you look at a solid wall, then you are seeing reflected photons bouncing off of the surface of the wall. The difference is a more opaque an object is, the more the light is diffused. There's more too it, ie color also plays a role. As this basically is the wavelength of the photons reflecting back. You all likely have seen illustrations of light passing through a prism and the rainbow colors it scatters.
guh, FINALLY, some good advice on glass..
If they are broken yes
I was so about the science part I forgot you were going to teach us some art lessons with it 😂
I love this for you.
This is so helpful!!
Never knew that's how shading on glass containers worked!
Glass does cast shadow. Shadow is just an absence of light. Since glass is not 100% transparent it casts shadow. Same with glasses. They focus light on one point by diverting it from other places thus creating an absence of light there - a shadow.
Relatively to the room the window does not cast a visible shadow but if you had a window and a hole in the wall, there would be a visible shadow.
I have a beaker right here with me and the only thing i want to add is the water line also cast an edge shadow for me. Whats interesting is one beaker has a far more cisible shadow than the other. Great content!
I find this a very interesting video that really helped me fix my art. Thank you forever for your help!
If you can see something then it means that's this thing isn't 100% transparent
Everything is absorbing and then reflects light the light back and casts shadows
*except light sources
2:15 imagine the sunlight traveling at the speed of light, just to reach you, only to be blocked by pesky little sunglasses who won’t let the sunlight reach your eyeballs.
How DARE we insult the sun in this way?!
I love this channel
glass does not perfectly transmit light and thus does cast a shadow even if it is slight to the point of unnoticible
but if we take your does transmit light perectly thing, it still is in shadow where the light does not reach through
glass is like a 6 dimensional surface
there's the position but also the angle you view it from
havent watched it but id say yes and more specifically a light to semi dark shadow depending on the thickness of the opject
How about you just check by putting a pane of glass in the sun? Because yes, glass DOES cast a shadow, unless it's perfect to the point of being nanotechnology and the light comes from a source exactly 90° to its plane. And even then I wouldn't be sure it doesn't. However, the shadow of a pane of glass is fainter than the shadow of its frame (if its has one) or any nearby opaque object.
The flashlight being a pointed light source is not a good test, you need something more evenly distributed like sunlight to be able to compare the shadowed area with its surroundings.
Does it, though?!
@@Wingedcanvas Yes, all flat pieces of super clear glass cast shadows. Both on the unnoticeable and noticeable scale. So long as light isnt dead on, you will get ever growing levels of shadow. You can see this at home by slowly angling a flat pane of clear glass to a close surface. The strength of the shadow is defined by the angle of light, focus of the light, thickness of the glass, and the strength of the light. Its strong enough of an effect to cast visible shadows even at a good distance away counting on the variables.
Love u ur the best love ya love ya💕💕💕
Thank you!!! You're so kind.
0:48 they're casting shadows
Infact everything casts a shadow except light sources
False, fire has no shadow
@@mrpickles-hb6zx yeah you're right
@@mrpickles-hb6zx Fire cast shadows too, but it's less apparent because they also cast light
@@mrpickles-hb6zx False, shadows are defined by something obstructing light. Fires have shadows because they obstruct light. We have experiments that can even show them. All known matter casts a shadow, and even fields can cast shadows by curving light around an object, thus obstructing light.
Ahh okay, it's all clear to me now.
HAHAHA. So punny.
Might be too late to ask a question, but would you consider that a colored glass is casting a colored Shadow? Or would it be okay/maybe better to consider the glass as a light source (powered by the light that passes through), that shines on the surface behind it (opposite the main light)?
Reason I ask is because I use screen blending layer for lighting & multiple blend layer for shading and I was thinking I should do the colored glass shadow/light on the screen layer. Since I assume where it casts, would be brighter than the local halftone value of the table
Genuine question, at 4:00 you show an inage of clouds and it almist looks like there are rays of darkness or rays of sahow coming off of them, why is that?
what about the impurities in windows?
If it didn’t, you wouldn’t be able to see glass
Or would you...
Windows still dim the light a little, made worse by any dirt on it
shadows are the abcess of light, so transparent glass shouldn't have an issue. It's when it becomes opaque or translucent due to cracking
Lol if it nighttime im sorry i can help you lol
Light is weird
Yes
YES
YEEEEESSSS
