A technical breakdown of how to draw in any focal length using the cone of vision. I highly recommend reading Scott Robertson's 'How to Draw' for more detailed explanations of perspective and technical drawing.

Yeesh what a dense subject! Would you like to see more technical in-depth videos like this in the future? 🤔
yes please 😅
Yes!
I like the summary at the end...
To paraphrase...
Low Focal Length = Vanishing Points are Close Together
High Focal Length = Vanishing Points are Far Apart
Thank you so much this was really helpful and your statement of dr. Draw was really amazing 🙏
Thanks for this overview of focal lengths! This has been a bit of a mystery for me for a while.
thank you this is very helpful. I probably won't really use the exact measuring method, but I think it's super important to understand how it works.
Thank you! For sure, unless you do technical perspective drawing (for architecture for example) I think you don't need to be 100% accurate with all of it.
it's wild to have something you learned by osmosis as a kid put into technical terms.
''It can be anything as long as it adds up to 90°''
Thank you for this golden clarification.

Glad it helped, thanks for watching! 😄
I finally understand the concept , thanks for explaining clearly
Man, what a great video... Keep up the good work, you're helping a lot of us :)
Really helpful! Excellent explanations and visuals. Thank you!
This is really a brilliant way to use 3D software to explain perspective sketching
Thanks! Very helpful!
You cleared so many things up for me! Thank you so much 🙏🏽❤
Wow! Really helpful, thank you so much❤
Wow, this is awesome; super interesting and thorough tutorial! Definitely worth learning how to fiddle with the angles; it can put so much power in your hands; you can literally create any lens effect you want in your drawings :D thank you very much!!
What an excellent video. Lovely work, thank you kindly. :)
Oh, just the vid I was looking for
Amazing content thank you!
Your video is sooo great ! You helped me a lot, thank you so much !!
I am really glad to hear it helped, Anissa! Thank you 😄
Very helpful video, especially part with the station point. I'm going through Scott Robertson's How To Draw Objects and Environments book and it's a lot to take in and sometimes I feel there's a missing step which this video covered. Cheers man
Thanks for watching! I agree, while that book is great the more you revisit it, it's super dense initially and hard to understand. Hope it helped! 😊
omg, I´ve been reading Scott Robertson´s book and it was so hard to grasp every term and concept, specially the cone of vision. Thank you so much for making this video :´)
You're welcome! It definitely is a book you'll need to read a few times before it makes sense 😅
Thank you, Daniel! This was very helpful! I was hoping you could explain why the telephoto cube version doesn't magnify like a camera lens? I'm sorry if I missed/misunderstood your explanation.
Glad it could help! What do you mean by magnify?
very great channel and educational content you have here, i am baffled you dont have more followers , but those who do are quite lucky !
Instead of estimating if you know SOHCAHTOA it's gonna be easy to get distance also if you understand triangle
Amazing, amazing video! However few questions here:
1. Why should the vanishing points always make 90* degree in total (60/30, 45/45 etc.)?
2. What does this angle represents exactly (the 90 degree one), is that the obejcets will have 90 degree angles or?
3. If our look/view is parralel to the ground, should it always be that the horizont crosses the cone of vision circle right at the center?
4. Do you usually use this tecnhique to put your vanishing points before you start a sketch so they are not completely random?
Thanks!
Thank you Simeon! And great questions!
1. The vanishing points add up to 90* to ensure that your objects have a right angle. If the vanishing points are closer together without using this method, it just means your objects most likely won't have 90* angles. Though this is a very technical and precise way of doing it - when doing art, I often just go by feel instead.
3. No, not necessarily. You can actually place the horizon line wherever you want, but it may mean that you'll start to see some distortion from the COV drawn from it. Remember, when looking straight down, the horizon line will shoot up off the page, and an auxiliary vanishing point will be created for objects converging downwards.
4. To be honest, I actually will use perspective grids and guides after a sketch to clean things up. When I'm drawing thumbnails, I focus more on the composition and mood/feeling, and then go in technically afterwards to ensure everything is all good.
Hope this helps!
@@DanielAngArt BIG thank you man! Oh so the 90* total degree for vanishing points doesent mean that whatever is drawn will have 90* angles of the form itselv but it will mean that they are rotated in 90 degree within perspective?
Hey!
I have a question in regards to the cone of vision.
Here you talk about the different focal lengths used.
For example, a higher focal length of for example 200mm would only take up a very tiny frame of the COV.
This makes sense, but I’ve seen people just take a small frame within the COV and draw within that frame, and it’s still a focal length of 35mm.
Wouldn’t a smaller frame within the COV make for a higher focal length?
How is this even possible?
your video is great, i think the next video for this series is on this topic which situations should we use each focal length (telephoto, standard and wide)? I think it requires a lot of knowledge related to storyboard or storytelling. hope you make it.
This is a great suggestion, thank you for watching!
The cone of vision for a 35mm lens isn't 60 degrees, it's 54.4.

The bit about 90 degrees for "drawing rectangles," I always understood that 90 degrees was chosen so that the grid creates squares- 45 on each side. Are we expressing the same thing or have I been misunderstanding this whole time?
That's correct, though you can change the degrees to rotate the cubes in space. Otherwise each cube you draw will always be front facing at 45° following the same vanishing points. You just have to make sure the angles both add up to 90° so it's still a cube 🙂
Very nice but it doesn’t answer the question. It was about how to implement focal lengths in one point perspective drawings. Thx a lot.
1st here :)
Question: will the horizon line be always in the middle of the image?
No, not necessarily! When creating actual art I'd recommend avoiding a 50/50 split between horizon and sky, but instead recommend 70/30. This just favours one side over the other and I think creates more appealing images 😄
@@DanielAngArt totally agree. My problem was applying that along side cone of vision. For some reason my mind twisted and I had troubles applying both things together xD any tip?
@@trigestigro4707 Think of your picture plane as something you 'overlay' over the horizon line and cone of vision. If you shift the picture plane up or down, it will change the effect of perspective in your art, BUT your cone of vision and convergence (focal length) remains the same regardless. I hope that helps! ☺
