I Became A Better Artist IMMEDIATELY After Understanding This | #shorts

Learn the concept of Fresnel for more realistic art! #shorts

[water-fallswebtoon]

I love how short yet useful this is. I honestly think these are the things artists don't tell beginners because once they know it, they just paint it without thinking about it and since it is something so "obvious", they don't tell us beginners assuming we will notice it.

Fun facts:

1; It is named after French engineer and physician Augustin-Jean Fresnel. His research lead to the acceptance of the idea that light is a wave, and he described the mathematical formula to calculate a whole bunch of optical phenomena, including the "Fresnel reflection" that was named after him. He also figured out a lot about the polarization of light, diffraction, refraction, and many other optical phenomena.

2; Fresnel reflection is why if you look at a lake, you can see through the water surface at your feet but the further you look the more reflective the surface appears. Generally, the lower the angle you are looking at the surface the more Fresnel reflection there is.

3; Fresnel also invented the Fresnel lens, a compact complex lens used in lighthouses to create their light beams, visible from very large distances, and later in some image projectors to magnify the image with a relatively flat lens (used. eg in those old school projectors teachers used with writing on transparent sheets).

never change Marco - unironically the best and most enlightening art guides on youtube

Works on human skin as well! Identifying areas that would be affected by Fresnel and ambient occlusion (rather than *only* thinking in terms of light and shadow from specific light sources) can instantly bump up the realism

I am literally doing a masters degree in optics and I never thought about applying knowledge from uni to painting. Thank you!

It's 8am. I wasn't ready for this. My mind is blown, and I haven't finished breakfast.

I always knew this was a thing, I just didn’t know it had an actual term for it. When you learn to actually SEE the world around you is when you become a better artist. It’s all about observing E-V-E-R-Y-T-H-I-N-G!

To anyone who is still not understanding this:

Imagine a surface of water viewed from an angle and compare that to almost a top-down view of the water surface.

The angled view is more reflective (of the sky) and the top-down view allows you to see more clearly into the depths of the water's color.

Best explanation for understanding fresnel i've heard - if you were standing in the shallow section of a lake you can see through the water in front of you, but as you look further you instead see the reflections of the sky and environment. The angle of light from your eye to the water is very tight directly in front of you, but becomes wider the further you look out creating the fresnel effect.

Marco literally blows my mind sometimes. Dude...you're truly a lord of knowledge.

[DrakeyMoodflare]

Damn learning frenel from game developing can be applied to drawing
(Mind-blowing!)

[IronShigeru]

The FOX engine was built around this, and that's how they managed to get such a realistic look in mgsv with its lighting. They did a big dissertation at GDC about it. Should be up on youtube.

[joeshmo]

Lighting has so much nuance, honestly. Thanks for breaking down another aspect for us!

[SpokoR]

Nice to have a bite of Fresnel with my breakfast. Thank you Marco

[Fieshs]

Literally no one does it like Marco Bucci. Always in it with superb tips

[bobxbaker]

10/10 tip, i've been trying to study reflections or specularity specifically and this pretty much confirm that what i observed is definitly a thing and i'm not crazy.
not only that, very good concise explanation of how it works.

another way you can apply this knowledge is on big pools of water like lakes and oceans.
the most easiest way to observe it is on still pools of water obviously.
the reflection becomes more and more opaque the shallower the angle becomes making the water surface less and less transparent.

I noticed this when I was a child playing on the hardwood floors of my house, but I sort of just accepted that's that how it was and never in a million years would have thought that it could a) be put into words b) actually be useful for something! Thank you for the really great content, keep up the good work!

[Angels-xist]

Very cool. My first thought is that depending on the texture of what has light cast on it, it’s going to be a softer or harder texture to the contrast or sometimes just change the tone of it. Like the textured book cover has a bit fuzzier lighting and the harder wood is sharper. It’s like the difference between matte, semi-glossy, or glossy. It can be hard to think of with something like fur or skin, but I think all you need to do is be observant. The difficult thing is to retain and memorize your observations.

I cannot believe how short your videos are and yet they are very informative...you're one of the best art teachers I've seen.

[cguibcx]

You and The Painting Coach give the best advice on the platform hands down! I know that's a bold statement but after watching both of your videos on color theory I noticed literally an overnight improvement in my work!!
