Description
I was wondering if I could demo breast dynamics with water balloons. Although I didn't have any as a reference, I tried to logically deduct how they they would behave. I find that water balloon with a string depicts the basic idea of breast dynamics rather well. As I'm not blessed with the privilege of having breasts, my points derive from my observations. Feel free to correct me if you find that I'm completely wrong.This demo is more like an intro for possible breasts demonstration part 2. But before the real thing, it's good to know the dynamics behind the breasts.
Numerable factors affects the shape all the time: the body position, motion, clothing... to mention some. Whatever force is manipulating the breasts, the gravity always takes place in some way or another. Obviously, the size of the breasts is a significant factor: the larger they are, the more evident the manifestation of gravity is. The basic shape is pretty much like a water drop, if the breast is hanging free. Here I demonstrate rather big breasts on flat surface.
Regardless of the size, it's the shape that make breasts attractive. So when I draw breasts, I:
-Apply gravity and support (force and opposite force).
-Make them look soft and squishy, yet firm
Hopefully you find this useful

hmm, i see, found it. then it's fine, i guess.
still, I think you should promote your art and suggest it to tutorial groups, because as i looked now your tuts are featured in few groups with not exactly teaching purpose.
looks like it is not a big deal for you, still it makes me sad. for example, guy from youtube makes money on views of the video(apparently) and/or earns attention with that.
being humble is nice, but letting other people sell fruits of your hard work is wrong.
but it is just my opinion, if someone stole my art i probably wouldn't know what to do. because self-criticizing artists like me tend to be like "meh, it was anyway not good enough" attitude, being too insecure in the outcome of their work.
wooow that pixiv artist, great works, thanks for the link. but i saw only illustrations, no tutorials(though i may be didn't find it because the site is not fully English).
btw, your tut is in Russian artists' group, do you happen to speak Russian?
anyway, good luck

I'm mostly drawing these for my own enjoyment and practice, but I also share them with everyone to help people out. Submitting things in groups is already extra work for me. I'm lazy guy when it comes to anything else but my art, so I'm not very active in dA community. If people request my tutorials to be included in group galleries, I accept the requests.
I didn't pay anything to learn drawing, which is why I also want to share my works for free. It's sad if people use my work to get money or attention, but there is very little I can do about that, (other than keep from uploading anything). For me drawing is ultimately a recreational hobby. Although I'm trying hard to become better at drawing, I don't really have any ambitious goals with it.
Yeah, he is really awesome, he is like my idol
As I said before, I'm lazy bum so I'll let people request having my works in their group galleries
Thanks, and if I just come up with new tutos, I will

Sometimes i forget that people draw for enjoyment xD i mean, when i look at good galleries full of works and with a pretty good page view rates i usually assume it is more than just a mere hobby.
but i see your point, this is really generous of you
nice, i'll be waiting ^^

In certain styles I like a slightly fake look to breasts, but only in drawings of course. Still, this is the preferred way I'd like breasts to be drawn. Well done Nsio, I hope everyone has passed this around the internet for reference by now.

i dont know either if this is right... but its kinda like what they would work like if they were THAT huge 0___0 im so glad i dont have to experience all that... gravity impacts myself XDDD

You tutorial got featured in a tutorials mashup I ran into on Tumblr here: god-hates-a-coward-sonny.tumbl…
Just thought you might want to know!

This and the second one are really going to help me out a lot. Thanks for making them!

This is amazing. I say you have the right idea going when it comes to simplicity.
👍: 0 ⏩: 0
They dont quite act like water balloons actually just to point that out. You've got the right idea though! This is great in means of the general idea. Instead of water balloons though think more...pudding. Pudding balloons, that adds a bit of that firmness that water balloons lack that breast have
👍: 0 ⏩: 1
I was aiming for general idea in order to simplify breasts into something easily understandable. But you are right, water balloon physics makes them a bit too squishy
👍: 0 ⏩: 1
In that respect you did awesome. I plan on using the tips in this to better my own drawings honestly. If it helps at all though, the water balloon idea works great for anime styled drawings since those are generally over-exaggerated anyways
👍: 0 ⏩: 1
If I may butt into this conversation late...
Fore-cite does make a point that this reference to "boob physics" does work well for anime in particular, but aside from these water balloons or the pudding balloons... Remember there is a body attached to the other side of that fat sack. It doesn't act on it's own just as the force of a water balloon would. With a hunk of flesh weighing down half of your object, and the object itself- while, yes, being a fat sack- is also made up of fatty tissues. They move, but they're no water balloons! Just things to keep in mind.
Enjoy your arting, all.

Butt in when ever you please my friend! It's never to late lol. And yes that also is something to remember, the reason I compare it more to pudding it because, well seriously have you ever filled a balloon with pudding? It really does have almost exactly the same consistency as breasts but that's really about it honestly, because you do have a very valid point. Balloons have one thing that makes them incomparable to breasts, they're not attached. Their movement is guided by the pectoral muscles underneath them and the muscles that pull and affect those muscles as well. Thank you for reminding me of that with your "there is a body attached" comment. In my excitement to finally get my pudding comparison I forgot to mention that little fact.

Omfg, THIS.
Hold on, I gotta show this to a few "pin-up" artists now! [link]

Breasts are NOT waterballoons, even the right image is anatomically not correct. A breast is much firmer (especially when young!). Keep in mind that breasts are firm, holding a pencil under them would actually be impossible. Young (even big!) breasts would NOT be able to hold it and the pencil would drop. Only saggy boobs work like that... Your theory would imply that the gravity would pull them down down down when standing up- without a bra. AKA saggy breasts. Yes those exist but not all boobs are that. Please, they have a mass and aren't just liquid.

Thanks for pointing out the firmness. True, breasts aren't water balloons. I just used them as an example for making it easier to understand the dynamics behind the breasts.
As I haven't done empiric research on real breasts, my points dervies from my observations, thinking and personal preferences. That said, I can't deny the fact that my drawing isn't anatomically correct and my views are biased. I usually don't want to draw too large breasts, because "my dynamics" makes them too liquid, just as you stated here.
Could you also take a look in my second part too and tell your opinion regarding the smaller breasts that I have demonstrated there?
👍: 0 ⏩: 1
This is both right and wrong. As to mass, yes: breasts have mass, but, outside of skin, and Cooper's ligaments, there is nothing to keep them from sagging, and quite soon, the mass related to size will produce a breast that WILL hold onto the pencil.
As to the pencil test: Yes, young breasts are firmer than older ones, but, if they're big enough, almost no matter how young the possessor, the pencil WILL remain in place under them. The simple weight of them will produce enough sag to hold onto the pencil. This is from a girlfriend of mine who was well endowed from the age of 12, and by 13 the pencil stayed in place.

This is awesome - I know a lot of people who's art would benefit from seeing this 
As a woman with a large chest though, I'd like to point out (for the sake of realistic breasts alone) that when they are that large, they do not tend to squish together that way. Gravity pulls them the way you illustrated, but a lot more away from each other. Trust me - I WISH my chest went together rather than away all the time, but there's a reason they make bras that do that for us ladies and our gals
👍: 0 ⏩: 1
I agree. I guess that's why most hentai comics include so forceful manipulation of breasts with either hands or... well, with anything.
Thank you a lot! It's always useful to hear women talking about their first hand experience about breasts
And yeah, it's all about the artist's preferences, and I don't think I'm completely unbiased drawer either!
I just submitted the second part [link] , so I would love to hear your opinions again, if you please!
👍: 0 ⏩: 1
Wow! I really love both part 1 and part 2 of these, especially your emphasis on the rib cage in part 2 
Again though, these are really great, and thank you for making them! Breast are all quite drastically different from woman to woman, and as artists we often take the parts of them we like the most for our drawings (even I don't draw my women with two different sized breast like the average woman has lol). But these basic guidelines you've created are very helpful and have definitely taught many people, I'm sure
👍: 0 ⏩: 1
Woah, then you really do know a thing or two about breasts! I'll heed your words
Yeah, I was had my doubts regarding the cleavage on "motherly" one. I believe the breasts do press together at least a little, but even if they do, it shouldn't be drawn with such bold lines or with lines at all. Though I think it had more to do with my urge to add a semi-cleavage there no matter what, so I believe in your explanation and remember it when I get to draw larger breasts next time
Thanks a lot for your opinions! Good to hear that you liked

LOL, what can I say? I've got *thrusts out her chest* experience
Glad I could help in any way! Keep up the great work!

omg. finally. I really hate it when artists draw women with rock hard balls of nothing on their chest which aren't affected by gravity or objects -.- I have chest myself and i always try to use it as a reference when drawing girls (finally i have a reason to be proud of the size) :L but its annoying when females have a rock hard chest, it makes the characters look fake and although im not attracted to girls i think it makes animated/fictional women look a lot more attractive when their chests are softer and more realistic :L
btw i think you've done a good job without a proper reference, you've got them down to a tee
👍: 0 ⏩: 1
I agree with you. That's why I'm aiming for certain shape and softness rather than fake bimbo breasts.
Heh thanks. I have had to resort in hentai quite a lot to get where I'm now.. ^^'
👍: 0 ⏩: 1
yeah I never understood the appeal of bimbo breasts either :L I think that most do, I do think about my own chest when im out and about, but I think more about "am I showing too much? are they too outlined?" rather than "I hope these look big enough to get some attention"
but I think it is mostly unintentional showing
even so, most hentai's do tend to have breasts unaffected by reality :L
👍: 0 ⏩: 1
Maybe it's just me doing too close observing... haha xD. I do look people a lot, including the breasts but not only them. The real world is full of excellent reference for everything.
True, most hentai is biased. Btw, I got the second part out, so have a look and tell your opinions! I would really appreciate your views!
