TUTORIAL: FORESHORTENING

TUTORIAL: FORESHORTENING

Hands Tutorial
Computer Coloring Tutorial by [info]cathybites

Okay, as I was trying to prepare for this tutorial, I realized that trying to show how-to's of foreshoretening is hard. So, I've pared my goals down to basically just showing how it's used, how often it's used and some small tips and tricks to create dynamic figures.

Notes:
1) If I don't stress it enough in other tutorials, I'll stress it now: PRACTICE. Lord, it took me ages to figure out how to do it, and I'm still no where near being confident with it.
2) This is my version of accomplishing foreshortening. There are other methods, some technical and some...technical. I use a lot of estimation and trial and error. And crying.
3) You must have a decent grasp of anatomy and figures before doing decent foreshortening.
4) As always, feel free to ask questions, add tips and tricks, correct me if I'm wrong. I'm learning as much as you are.


Foreshortening


What is foreshortening? It's the process you use to successfully translate a 3D figure onto a 2D canvas and still make it look like it's 3D on paper.



Basic stuff--

-- Foreshortening and perspective go hand-in-hand.
But! I still say you can do a pretty nice
foreshortening without yet perfecting perspective.
Because I suck at perspective too.

--Foreshortening also is combined with limb alignment.
*Read [info]ani_bester's explanation!
* See [info]fools_trifle's visual example!

-- Foreshortening is awesome. Ok, this
isn't educational, but! It's true! It makes
drawing-time fun and happy. Practice and
perfect!




------------------------------------------------------------------------------

LINES!

One technical thing I have to mention, is the
key of getting well-placed lines. Yes, foreshortening
can be accomplished without them, but lines give illusion and that's what foreshortening is all about.

The animated example on the right shows how lines can aid foreshortening by creating the illusion of lots of land-gap between the trees.



------------------------------------------------------------------------------

DYNAMICS!

Foreshortening can also help you create really dynamic, high-action poses (above). You can take full advantage of crazy poses and twist your people in all sorts of ways. And if you know your stuff, then they look kick-ass doing so.

However, it can also be used for more mundane things - folding arms, drinking from a cup, sitting down. These sort of actions are more likely to appear in fanart (ie, Harry Potter fanart), so it's always important to know in everything you draw.


Foreshortening does not only apply to full bodies either. It is used when drawing heads, feet and, of course, hands.




-----------------------------------------------------------------------------

When trying to wrap your head around foreshortening, there are two main techniques to keep in mind: blocks and circles.

BLOCKS



One way to view the human body is in blocks. I'm sure you've all heard this before, and it's true, especially when it comes to applying foreshortening. Once you see bodies as little building pieces, you'll understand how a leg muscle should curve or the perspective that an arm should be raised.

Each limb cylinder is tilted in a certain way, and when you build the body and clothing (optional, of course) around them, you adhere to the curves each cylinder tilts to. Does that make sense? Check out the animation to see what I mean.

If you look at the elbow bend of the left arm (the one closest to you), for example, both the foreshortening of the forearm and the sleeve that folds around it conform to the curve of the tilted cylinder.

Watch each of the joints to see how the eventual clothing folds curve around them. They correspond to the curve! (hopefully!)


CIRCLES


I am a huge fan of thumbnails, outlines and rough sketches before going on to the detailing and clean copy. Therefore, when I do foreshortening, I draw a lot of circles. Or rather, ovals. The ovals sort of 'slice' the limb cylinders at key points so I can get an idea if I'm placing the arm high enough and foreshortening it properly.

These circles are purely for rough use only, although clothing folds can also abide and follow their curves. I find circles fantastic, actually, for making sure your random clothing folds look natural and believable.



---------------------------------------------------------------------------

And now to apply the methods! Via my nemesis friend, artpad.art.com.

I Have Mutant Powah! - showing foreshortening of the arm, hand and head. The shoulders are FAR too slim, and if I was actually finishing this, I'd either broaden the shoulders or shrink the head.

Snobby Snob - showing foreshortening of the head. Of course, doing portraiture from any angle is a whole different story.

So Lazy - showing foreshortening of the legs. I put color to indicate the separate cylindrical leg parts, and how the jeans would curve around it.

Are You Talkin' To Me? - showing foreshortening of the torso, arm and legs. Circles, circles circles!

Anyway, I hope that's some sort of help, and pelase, if you have questions or confusions, please feel free to ask.




NEXT UP: FEET!
Yup, shoes too!

You are awesome for doing these !
I wanna buy the book when it comes out =P

It's interesting with forshortening, I'm usually ok up until I try and turn the circles and such into actual body parts. Somehow between the intial form layout and during the form into actual human shapes, something always goes horribly wrong. It's like I have rouble translating the circles and such into actual parts.

That's why I usually go for the scribbly method, in which I just build up scribbles until I get it right. It's an interesting way to get mass, but it also insures my slavery to a lightbox if I want "clean" pictures.

It also makes for a lousy tutorial (well just you know scribble, see, after 42 hundred random lines, it's almost an arm!)

Ohhhhh one good thing to cover if you are taking tutorial suggestions. How to use align knees and elbows in perspective.

Thanks so much for these -- I suspect I'm gong to get a lot of use out of them! (Finally dragged out the sketchbook again this weekend, and I'm going to be working on poses... whee, watch me suck practice endlessly.... :)

[info]glockgal

October 29 2005, 06:56:45 UTC 6 years ago

Oh my god, thank you SO MUCH!! Just the fact that you brought out the sketchbook again makes me just glee with...glee. That's fantastic!

I love this so much, very useful as a tutorial, and the best part is seeing that you have the exact same problems with artpad that I do. Which might not seem like the best to you, but, it's SO very nice not to be alone in the universe, y'know?

*g*

Thanks for doing these!!

[info]glockgal

October 29 2005, 06:58:09 UTC 6 years ago

Yeah? You mean the problem that artpad is PURE EVIL? *hee* Definitely glad to know I'm not alone as well, hehe.

This is probably the best drawing tutorial I've seen out there, not just for foreshortening but for anything. And can I say how much I love the animations? Even if there was no other content, the animations alone are fantastic. :D

[info]glockgal

October 29 2005, 07:00:34 UTC 6 years ago

Eee thank you and I'm glad you are happy with it! I'm so gld to be useful. *MWAH*

Omg. I am sooo tired right now but I can't wait to give this a looksie tomorrow. And I am positively vibrating in anticipation of the foot and shoe tutorial. 8">

[info]glockgal

October 29 2005, 07:01:57 UTC 6 years ago

*HEE* I hope it lives up to expectations. Maybe I'll just give up on the whole feet thing and just draw tons of pretty shoes! *GRIN*

I love no-work!glock.. she does so many cool art things!

Foreshortening is HARD. But a fun challenge... and, if you can do it, makes your picture look awesomerz. Feet are tough, too! I look forward to that one, because feet are probably my least favorite things to draw - oh, and also NOSES.. I hate noses! And arms. .. .Why do I draw at all?? Hehe

[info]glockgal

October 29 2005, 17:12:23 UTC 6 years ago

I knowwww! I'm gonna miss all this lovely free time when I get back to work!

Foreshortening is TOTALLY hard.

and yay for feet tutorial!!!

[info]glockgal

October 29 2005, 17:13:14 UTC 6 years ago

YAY!!! Explanations are hard, so I'm glad to know I'm being somewhat cogent.

FEET! EIW. But yay!

October 29 2005, 07:18:41 UTC 6 years ago

This is so much fun--I haven't drawn in years (picked singing over art for the time being--this could change, 'specially if my voice craps out on me as I get older), but I love seeing how you do stuff.

And yes, feet, looking forward to that--you draw the sexiest feet ever. *grins*

[info]glockgal

October 29 2005, 17:25:02 UTC 6 years ago

Awww, yay! And yay for singing! I stick to doing that really loudly in the car, hee heee.

And thank you, awwww! Feet are still somewhat my bane, so the next tutorial will give me some well-needed practice too!

October 29 2005, 07:30:41 UTC 6 years ago

Neat!

One of the better tutorials on foreshortening I've come across both in print and online. (I learnt foreshortening from how to draw comics the marvel way). I really need to pull out my pencils and sketch pad. You're making me want to draw again! :D

I like the chatty style, and the clean uncluttered lay out of this, well done! :D

[info]glockgal

October 29 2005, 17:28:57 UTC 6 years ago

Yay! I own that book as well! I know I picked up a few good tips from that as well.

I was tempted, actually, to do research and scan in books and stuff, but then I figured that that would be somewhat redundant and boring and unfeeling. So I'm reallyreally glad this is working out for you!

ah glock! You make me so happy! *blissful sigh* Love the artpad thingies cause it feels like I'm watching the MASTAH work!!! So KOOOOLLLLLL!!!1!!

dude, are you going to the lumos thingy?? Cause the pictures you guys posted of TWH looked super cool and I'm tempted to sign up!! Probably not to take part in the games cause my head tends to be a magnet for balls but, ah! To see glorious fanartists at work would be such a treat. Plus my brother lives there so maybe I can bunk with him! ^__^

[info]glockgal

October 29 2005, 17:32:29 UTC 6 years ago

Awww yay!!! Man, artpad is soooo evil, but I'm learning it. Slowly but surely!

I AM TOTALLY DOING LUMOS!!! I know Fiendling and Cathybites are going as well, so, YAY! If you could come, that would RULE, OMG!!!! Witching Hour was killer-fun, man.

Thanks for the tutorial! After years of fade-to-nothing arms and extra long sleeves in my sketchbook, I finally tackled hands, thanks to you. :) I'll be referring back to these, and I can't wait for feet! I love feet. Shoes, I could use some work, but I think feet are fun. :D

[info]glockgal

October 29 2005, 17:36:18 UTC 6 years ago

Oh that is SO cool to hear! I know hands can be extremely intimidating, but once you get the hang of them, they are so so fun.

And yay that you love feet, cause I hate 'em! So if you have any pointers for the next tutorial, don't hesitate to pipe in, babe!

i recently learned about that trick myself, the one with the landscape. and i love playing with sketching clothing folds. the one foreshortening problem that gives me the biggest headache is the arm one... will have to work on that.

[info]glockgal

Yay! Isn't the lines awesome! I totally love playing with sktch folds as well.

What sorts of problems do you have with arms? *curious*

Very cool tutorial! My own attempts at foreshortening tend to involve lots of trial and error, with a whole bunch of sucky scribbled attempts until one looks more or less acceptable, and then copying that on a new sheet via lightbox.

What I found useful to reduce the number of completely horrifying trials especially for arms and legs though was to first pay close attention to where the joints actually are in space for a pose, figure out where that point would be on the 2D plane of the paper and then draw the limbs, instead of trying to figure out how long or short the actual body parts ought to appear by perspective rules for geometrical objects. Also to figure out the 2D positions of joints mentally turning a body sometimes helps me, like when I want to draw someone reclining in a front view, the "mental image" of the pose might be much clearer/easier in the structure when drawn from the side, because you'd see more, and then I first sketch that, and afterwards figure out how far apart the key points of the body would appear vertically were I to look at it from the front (you know, like with those projection lines you do for perspective, only not quite so elaborate?). Somehow when I try to place cylinders right away, some part of my brain never wants to believe how little you sometimes see of a limb or the body, and tries to make all parts of it visible even when they really aren't. But when I'm sure where the joints are, the part of my brain that's stuck at the stage of a five-year old drawing stick figures representing concepts of objects and people rather than their actual look will shut up faster. Well sometimes anyway. ;)

[info]glockgal

October 29 2005, 17:48:46 UTC 6 years ago

Yessss. While I am not against using perspective and strict geometrical rules for foreshortening on a person, I simply do not find it works properly for me. A human body is organic, after all!

And I am TOTALLY with you about trying to show the entire limb, even when it's foreshortened. It took me SO long to break out of that habit, because it's so hard! thank god for staring at awesome fanart and learning that no - I can indeed hide and not show parts and the image will still be understood by viewers. *G*

Thank you for sharing! That's awesome, luv.

Thanks!


And feet! My favourite bits! Can't wait. :)

My gratitude for this tutorial knows no bounds. :D I'm going to add this and every other tutorial you make to my memories.

I've never had any art lessons and had no idea of blocks and circles; I just draw by instinct. So this is most useful. Thanks! :)

[info]glockgal

October 29 2005, 17:54:37 UTC 6 years ago

Oh dude, yay! I'm so glad to be of help.

Drawing by instinct - high five to that! I'd love to take some formal art lessons myself one day, but hey - trial and error ain't that bad if it got me this far. Yays!

These just look such fun, and are so intimidating. Also, the tiny penis on the foreshortened guy is my favourite. If you did not draw one, please ignore my pervy mind.

[info]glockgal

October 29 2005, 17:55:02 UTC 6 years ago

AHAHAH IT IS A TINY PENIS!!! *pounces on you*

October 29 2005, 12:17:50 UTC 6 years ago

I'm impressed at the work you're doing putting together a complete figure drawing tutorial. It's also activating my inner tutor, so here's my contribution - perspective lines for body alignment. It's something I've found very useful, especially when it comes to keeping limbs in proportion (arms and legs at equal length) and ensuring the figure keeps it's equilibrium and is actually resting on something (ground, chair, someone's lap, whatever).
I also find indicating the center line of the torso, legs, etc, helpful - especially when the body is twisted.
Otherwise - the mirror is my friend. It shows me just haw little of my thigh is actually visible, when I sit with my legs out stretched before me, and how much of my torso is covered by an outstretched hand :)

Illustration of the perspective line thing:

Hope it's okay for me to comment with this...

[info]glockgal

October 29 2005, 16:41:47 UTC 6 years ago

This is BRILLIANT. May I link it up with the tutorial and credit you? I was ignorant about this technical aspect until [info]ani_bester mentioned it, hee. I love you for doing this and taking the time to sketch out a visual!

Eee, this is so awesome. *cheers*
