I love these videos. I have learned so much from you!!!
Thank you. Lovely to hear!
the first time i watch this video was in art class when our teacher showed it to us to help further our understanding. We were in 8th grade, so just wanted to let you know that once upon a time you had like 20 thirteen year olds grouped together to watch your video and every single one of them was fascinated by how clean your sketches are. some kid called you a hacker for sketching with a pen.
Awesome to hear this, thank you for letting me know! Hacker? 😂😂
Love this channel. Extremely clear, clean and informative. Great work
Michael Townsend thank you very much. Really appreciated!!
Thank you so much. I always wondered how to draw shadows and felt it was super complicated. Now I see its actually so simple and interesting.
Thanks so much for the feedback!
This is very informative. Your series of videos is brilliant! Please keep them coming!
Mary Wilson thank you. I’ve got loads of ideas for more videos. They’re on their way!
I’m in college for industrial product design. We are just starting to cover casting shadows, this was super helpful! Thank you!
Great to hear, thanks
This is really good for the beginners who want to be a designer! Really clear your voice and explain. Well done! Thanks for sharing this!
Korean Artist TV thank you very much. Really enjoying watching your channel!!
Thank you very much, this is so simple to follow especially the first part of this video, the source light, direction of light and shadow direction !!! this is so articulate and well explain in short period of time. Thank you for your time and effort....i'm your subscriber now !!!!
Thank you! It’s very much appreciated!!
It would be worth pointing out in this tutorial the difference between an artificial light source and the sun. If the shadow is cast by the sun then the light rays would be parallel due to the sun's great distance. If the light source is an artificial one e.g. a street lamp, then the light rays can be drawn from the light source. A simple explanation is that when you move sideways from an artificial light, the light stays fixed in its position whereas if you try and move sideways from the sun, then sun moves with you. Therefore the sun rays are parallel. It is a common error perpetuated in many perspective tutorials.
I get what you’re saying but would suggests that’s better covered in a follow up video rather than one that covers the principle in short, for an audience that want the fundamentals, to develop their sketching. To include it at the start might overcomplicate for some. I wouldn’t describe this as perpetuating an error.
So, as I understand this particular video would be under the sunlight right??
@@karloatlYes, or a distant light source rather than a nearby one
Thank you very much for such a simple but important way of cast shadow drawing.
My pleasure!!
Most simple easily explained video I've found thanks!
My pleasure, I’m pleased it was useful.
Thanks for this video im just a beginner and was looking for a video simple enough to understand. Job done. Cheers!
You’re very welcome!
That was very satisfying to watch 👍🏼
OTGill ! Thank you!
highly under-rated, awesome content, great video editing :)

It’s so easy to follow and understand and remember. Please have more videos
Thank you
Very nice demonstration- Thanks!
Thank you!
Thanks for the explanations. Great info.
Nory Gonzalez thank you
Simply amazing. Thanks!
Thank you!!
Very helpful video! Could you please make a video on when the shadow interacts with another object.
Pralay Bera good idea, thank you.
Would love to see that also :)
Third this comment! Would help a lot
So helpful. And very clear. Thank you.
Thanks for the feedback
Fantastic video! Please keep them up 😊
Rowan Spear many thanks!
Utterly brilliant - crystal clear in its essences and encouraging in its tone - no pun intended! Thank you very much.
Really appreciate this, thank you!
@@productdesignermaker My pleasure - you have a very real gift - so be encouraged and we can all lead lives mutually enriched! Acquiring skills leads to, albeit nascent competence which in turn feeds our confidence in the 'I think I can' rather than 'I cannot...'. I am a musician and am exploring my love of colour and form - cf Paul Klee and 'Painting Music' - so you have really reawakened my Technical Drawing lessons of many years ago when it was compulsory at age 12 to do Art or TD! My thanks have real deep connections - so forgive the detail, but I sense you will get why your skills and gifts have 'landed' for me.
Thank you, it's so useful for me
My pleasure, thank you.
Very helpful! Thank You!
My pleasure. Thanks for watching.
Thank you for your videos. They have been very helpful. Suggestion: a video on stacked shapes with cast shadows.
Great to hear. Thanks for the suggestion, sounds like a good idea.
Thank you VERY much! ♥
My pleasure. Thank you.
thank you for explaining it so simply. Great video
aditya srivastava my pleasure, thank you!
@@productdesignermaker Hey just a request can you make a video explaining how to do shading for two objects kept on top of one another. Like a sphere on a cylinder or Cube on a Cylinder. Thank you
aditya srivastava yes, I will do at some point. I have a few videos to complete first, but I will do.
@@productdesignermaker Thank you
This is something super interesting
Thanks very much.
Thank you !
Thank you too!
This is great. It's a little simplified. The light direction and light angle are parallel only when the light direction is parallel to the picture plane (the observer). When the light direction is oblique to the picture plane (the observer), the parallel lines (light direction and light angle) converge to their respective vanishing point. Will you be covering this or have you already?
Sunaya correct! I’m trying to make my videos accessible to all, so that confidence is built and sketching is loose and expressive. My focus is mostly upon helping designers with communication skills. Shadows suggesting shape and form, quickly put down and building a more communicative page of ideas, efficiently and economically. Great idea to produce a ‘part 2’ in more depth, for those wanting more. Thank you for your feedback.
Thank for your helpful vid 🤗🤗
An absolute pleasure!
this is awesome
Thank you!
Very well explained.....

This is very important and helpful video for begganer.
Good to hear it’s helpful.
If I want to simplify the head in simple shapes can I use this method to get an accurate lighting? Very helpful video
Thank you. If I’ve understood your correctly, yes, I would say so.
Your drawing skills are super rare 🔥👄🔥

Wow
great video

Awesome... If one example of sphere would have been there ... this would perfect... But thank you for this awesome... information...
Thank you. That’s a good idea for a future video, thank you.
What video shall I make next?
please for shadows of floating objects!! I cant get the hang of it
how to cast shadows when boxes and cylinders and any shapes are next to each other or behind or in front
@@PurplePotatoBro I was going to say the same thing xD that and shadows cating over other non flat objects
Can you do this for the nose, eye sockets and mouth?
@@kenkenichi7461 that’s not really my specialism!
The objective of the product design and its sketch is to generate a scene with artificial light, we ourselves are somehow placing a cold white LED projector as a photographer does in his studio when he wants to advertise a product. We never deal with sunlight and ambient light because it is not our intention to seek an artistic purpose with a sentimental weight, but that our sketch can be understood in the quickest and clearest way by our client. I clarify this because there are comments that demand to deepen the subject when in fact with the basic principles such as light, shadow, shadow cast and translucent objects is more than enough in our area.
Love this! Thank you!
Can you explain the Cast shadows itself and others to objects (not the floor planes)? I dont know how you did the 4th
Ben Tal I hope to do more videos on this at some point.
Any books you recommended that I can use as reference?
You have taught me what my University has not.
I’m sorry to hear that, but it’s good to know my videos have been useful too!
Hi there! I have a few questions:
- How do you get the angle of the light - is it something that WE determine?
- If so, in the case where the light source is from the side and not the top, if there are multiple objects, the angle will vary depending on the distance of the object to the light source. Therefore how do you calculate the varying distance of the cast shadow of each object as it progresses further from the light source?
- How do you determine the shape and angle of the cast shadow of an inorganic object, especially with the above question in mind?
If it's too long of an explanation to be written down, I'd just as happily gobble up a video that anyone can kindly redirect me to! I'm legitimately baffled by this and I've got unfinished work from months ago as I've been absolutely clueless hahaha
Hi, i’ll try and answer.
We Determine the angle of the light ourselves. There is no right or wrong. Imagine a pole with a spotlight attached to the top. The spotlight can be angled however you like, and the pole can be any length you like.
If the light source is from the side and not the top, just assume that it is on the top. Any light from below the top would still hit the object and cast a shadow.
Do you mean ‘organic’ ie amorphous? If so, look for any distinguishing points that can be used to reference from.
I guess if the main light source is close like a lamp you wouldn't make the lines parallel though and would have them almost like a perspective point.
Name yep. That’s right.
Genial👍
Thank you
What kind of light technique is this? I saw other youtube do it differently. Would love to know! 😁
I'm not sure that it has a title? Just sketching cast shadows - sorry!
I think you forgot the sphere but its alright. Thanks for the video, it was really really helpful!
Did I? Oops! Ah, I think I see what you mean.... it’s just a circle!
very god!
Thank you!
❤❤❤
🙏🙏
Very useful, Can u plz put an video for cast shadow in perspective
I’m not entirely sure what you mean, sorry. These shapes are drawn in perspective. Let me know what you mean and I’ll have a think.
Like two point perspective, one point perspective how to place light source.and how shadow will converge as per vainshing point.
Suppose an object placed before wall.how the shadow falls on wall
Yes it's Steadler pens!
Rustam Karimov absolutely!
Hey loved ur video but can u tell me why are the light direction lines angled and do not go straight following the lines of the cube ?
Thank you. They can go straight, but if they do, the shadow will run on indefinitely…. If I’ve understood your question?
@@productdesignermaker Thanks a lot u cleared my doubt.
@@samarjeetnalavade4817 my pleasure
I saw another tutorial where the 4 points on the cube were connected to the light direction point. Same kinda situation for the light source point and the top 4 points. So that brings the question, how are all of the lines parallel?
Hi, I’ve just simplified it a little and assumed a more ambient, rather than spot light.
@@productdesignermaker That information should be in the title, because otherwise you are teaching wrong things to people who don't know better.
@@humane.t.709 I see your point, but it isn’t wrong. It’s a simple way of drawing cast shadows. A ‘How to draw in perspective’ video wouldn’t necessarily jump straight into delivering a complex 3 (or more) point perspective tutorial.
I want to cry!
Daniel B. Alzate don’t let it get to you!
@@productdesignermaker thanks! I will never give up.
Daniel B. Alzate I can sense you have an inner strength not normally known to man. You’ve got this!
Good tutorial, little suggestion is please dont add BGM in tutorials because it sounds like noise when I try to speed up video. Thankyou so much for sharing , I learnt a lot .
Thanks for the feedback.
I didn't even know there is geometry in drawing shadow too
Great video
Every day is a school day 😀
Fue muy facil
Nunca es facil! 😂😂
How do we know how long to draw the light source and where it’s ground point will be at ?
You can position it anywhere, and at any height. Hope this helps.
@@productdesignermaker Thanks again
@@JaneDoe-ht4tg my pleasure!
I want to know about the cast shadow on near light of cone and cylinder
When I get the time, I’ll make a video to explain shadows on other objects.
i like your cross hatching.cong
Thank you 🙏
Can you please make a tutorial on how to practice making clean straight line without ruler please? I hope you read this, Thank you! ❤️
If you read this, can you also make video for part 2 of cast shadow with more complex shape? for example like shapes that has no edges, sphere, etc.
Hi, thanks very much for the suggestion. Funnily enough, this is central to a course that I’m writing at the moment (well, editing - it’s nearly done). The course has taken several months to put together, and is based upon many years of teaching experience, so it won’t be free I’m afraid. It will cover all the fundamentals that just don’t seem to be taught. Sorry it won’t be free, but may feature in brief at some point on my channel.
@@productdesignermaker i hope i can afford it because your way of teaching is very easy to follow, but if i can't, i'll still keep supporting you through watching your youtube videos and saving up money. Thank you so much !❤️
@@lunafox5571 thank you
Sir, I want to master the fundamentals of perspective drawing in detail thoroughly, can you please suggest me a video? thank you sir.
Sure, this one ua-cam.com/video/SZ_bF7KnWQg/v-deo.html
And this one ua-cam.com/video/zPDbca83V5Y/v-deo.html
@@productdesignermaker Thank you Sir
umm how do we decide what would be the light angle ?
Anisha k it comes from the top of the light source. Place your light source anywhere you like in theory (though it’s most straightforward when it’s off to the left or right, and backwards a bit), and your light angle comes from the top of it and passes through the light direction line. Hope this helps.
Could someone please explain to me why the LIGHT ANGLE (red line) is drawn parallel to other light angles on a cube? If the drawing is of a single-source light, shouldn't each of the light angles be drawn FROM the light to meet each vertices?... Meaning they all can't be parallel to each other? Thank you :'(!
Yep, I’ve simplified it a little to have the light source as an ambient or general light source. If the light angle lines all came from one point, that would describe a spot light. You make a good point, but since it’s potentially a complicated concept, it can be off putting for people developing their skills, so hopefully I’ve made it a bit more accessible.
This helps tremendously. Thanks for the clarification!
genio crack lider
🙂
Can i asked a question ? how to cast shadow for a spheres ?
Great question. I should make a video.
Yeah... Sir isnt getti g that homework he wanted
Walkerz _XD No? Think of the skills you’ll have acquired if you do it! You can become a pro! Also, sir is a pretty shrewd bloke if he’s sent you here! He’s got my respect!
Edit: make sure to tell sir that I think he’s cool!
Did you delete your previous videos on prototyping and such?
Man Fish-Eagle my manufacturing processes videos are still up. I haven’t yet done any specifically prototyping videos yet but I’m planning to at some point soon.
Woops, I got you confused with producttank. My bad!
Man Fish-Eagle I’m flattered! 😂
Can you use this metod on drawing shadow in building and human?
Yorozura. id definitely for buildings. You could adapt it for the body. It will work for still life.
@@productdesignermaker thanks, your explanation is really good and this video should have more view, as thanks I didn't skip the ad
Yorozura. id haha! Thank you! Very much appreciated!
@@productdesignermaker can I ask you something? Where to put the light direction, I understand where to put the light source but I notice that if I change where to put the light direction, the shape of the shadow will be different, can you please answer this because it's make me frustrated for a while
Yorozura. id hi there. The light source can be anywhere, and the light direction can be anywhere too (so long as it comes from the base of the light source). Imagine a sun rising on the left side of your page, and setting on the right side of your page. It can be anywhere in between, and the shadow will change all day, depending upon the time. I hope this makes sense.
Ruler is not available of this blogger. Amazing..
Haha, no rulers allowed!
how do i know the light angle and direction?
PopcornSticker you choose. They can be anywhere within reason. If you put the light source to the left hand side of the paper, then bring the light direction towards the right hand side. The light angle just goes down to cross the light direction (and it starts from the top of the light source). I hope this helps. If you’re still struggling, go back and have another look at the instructions towards the start of the video.
@@productdesignermaker soo the angle depends on height of the light source, and the direction - on its position.
PopcornSticker yep, if your light source it a tall strip light, the light angle starts from high up. If it’s a low lamp on the floor, it starts from low down.
your work is great, but it is better to draw the light source to keep following what you are doing and depend on what!
Not fully sure what you mean I’m afraid
Actually, I think I understand. You suggest including a sketch of the light source itself. Yep, I can see that would be helpful in some cases. Thanks for the comment.
First you diagrams are detailed to perfection
Only you did not tell us why it is cast shadows
Shadows are cast by the solid shape. Sorry if I’ve misunderstood the question.
Great! But forgot sphere shadow......
Did I? Just an ellipse.
gg easy
Thank you!
Your videos are very helpful, but making them time laps is very annoying for new learners.
Ali Mohammadhosein thanks for your thoughts. It’s a difficult one and no solution fits all. What I’m trying to do is to explain and demonstrate a process at the start of the video, then demonstrate it at speed afterwards. This is so that people stay to watch the whole video without getting bored or distracted. You can slow the video down and watch it in more detail. Hope this helps.
product designer maker thanks, You are right.My main problem is making my hand stable like you. How this can be achieved?
Ali Mohammadhosein the main thing is to try and lock out your wrist. Work as much as possible from your elbow. Turn the page regularly to suit your natural straight line position. I’m planning a few videos on this.
product designer maker Thanks a lot for your advise 🙏🙏
the was really distracting i think it is too loud
So distracting it distracted you from saying what was so distracting? 😂 I’m guessing it was the music that was distracting? Always appreciate the feedback, thank you.
@productdesignermaker lol, yes it was the music, sorry big typo
Fantastic video! Please keep them up 😊
Very helpful video! Could you please make a video on when the shadow interacts with another object.
Yes, soon
