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

So, breasts are not air balloons, they're water abused balloons. Gotcha!

I appreciate you a lot for this!
Seriously made me understand Boob mechanics, like fuck man tits are wonderful but why must they be so difficult to beginners ;-;

I think this is a damn good tutorial and not just for 2D artists but also for 3D artists. Even if you opt for producing fake boobs like LordDonovan talks about below, there are still a certain amount of physics that have to be addressed. Even air and silicon behave in accordance with the laws of gravity and so forth to an extent. So again, this is a fantastic sets of examples and I commend you for your efforts. Great job!

My only issue with tutorials for drawing breasts such as these is that they assume everyone prefers total naturalism and realism. I don't deny at all that the final image is correct in its depiction of realistic soft and squishyness, but, well... if I wanted absolute realism I'd look at a photo, and the Internet's already got more photos of boobs than you could enjoy in a single lifetime. Drawings are for the best you can possibly imagine, and my ideal boobs are somewhere between the "wrong" and the "right" examples. The wrong one is definitely ignoring gravity and squish far too much, but the right one is less round than I like. I don't want them perfectly spherical but generally fairly close, as long as gravity's the only significant factor. And if you ask me, the "good" picture is applying too much deformation for gravity alone.
Anyway, to each his own, I'm not posting to knock other people's opinions to be clear. I just take issue with the assumption that people don't draw them "right" and/or don't prefer "correct" depictions only due to ignorance or their inability to do better. Some people are perfectly aware of what's realistic, and simply prefer breasts stylized in favor of unrealistic partially-gravity-defying roundness. Which isn't really inherently different from the preference for depicting breasts unrealistically large - average by fictional standards is big by real life standards, and big by fictional standards is incredibly rare at best in reality - so clearly artistic liberties are already the norm. Yet only the extra firm and round fans get guide after guide such as this treating their preference like it's simply an oversight of ignorance to be fixed by education, rather than a fully aware and informed choice. Of course people who like 'em extra big know that's unrealistic and don't care, so why can't the same go for those who like 'em extra round? Quit mistaking different tastes for not knowing better. I mean, the girl in this guide has a clearly stylized face, but nobody's accusing the artist of not knowing the difference between real faces and anime faces obviously, it's an intentional stylistic preference. Well, same deal with liking firm round boobs.
And as long as I'm ranting, not all breasts have the same squishyness anyway, in reality there is indeed a natural variance in the balance and strength of supportive tissue versus the fat they're supporting. In which case, even totally realistically, there isn't one absolute correct softness depiction, some breasts do hold their shape more steadfastly than others, breasts of the same mass can and do vary in shape/sag/etc. So while the first example is definitely impossibly and unappealingly spherical for boobs resting on a counter, I do think breasts could realistically be more firm and round in that context than the "correct" depiction shows as well. And as long it's fine to draw them on the extreme end of the realistic -size- range, then drawing them on the same extreme for realistic -firmness- should be just as valid.

It's good to note that generally tutorials and guides are made to explain how things are and work in general or in reality. They are made to help people to learn the basic concepts and then find their own way of doing things. In that sense this tutorial isn't especially good, for it clearly tilts towards the squishy extremity.
Anyway, we both agree that the first example clearly isn't good one. But I don't think your preference is in between the bad and good example. I assume that if possible, the drawing is well executed. So a good archetype of nearly spherical breasts is on its own branch of possible good examples. I don't think we have any disagreement there.
I have no problem with less natural breasts as long as they and the rest of the drawings are well executed. If we look at the first example, it's clear that no one draws like that (quite well executed overall drawing except for the breasts). I believe that the majority of people who draw bad spherical boobs, it's not merely a preference. Often times they aren't very good at drawing anything in general, so it might actually be just about ignorance and lack of skill, in fact, it's very likely. I say this because I drew badly at first because of ignorance. I would say that its at least worth investigating whether there are factors that make people draw badly. It's important to identify whether the outcome is genuine and artistically intentional instead of hiding behind excuses like "this is my style", especially if the artist is a beginner or has low level of mastery (for years spent on drawing alone don't indicate anything, I had spend 6 years on drawing before I realized I was bad).
To me the kind of argumentation you used sounds more like an excuse, like you were saying "not all X look the same, therefore there is no reason to follow any rule at all". I believe there are universal factors which make the drawings work, whether they are realistic or not. IalsoΒ believe there are artists who are good at drawing spherical boobs. Those are rare though, the vast majority aren't so good. The same can be said for the other extremity as well. I'm fairly confident that many people have ulterior motives for drawing the way the do, I'm not exception to that. From Jungian perspective, I have met my own shadow, I know perfectly well why I draw certain things and in certain way. However, I also want to improve so it's been crucial to identify my own shadowy desires and tendencies. And I'm not done with that, I keep working on getting better. I don't mind if people want to follow their preferences even at the cost of not improving in general. It's their choice.

I think there's a great need for help when it comes the drawing small boobs. Going from circles to something more resembling actual breasts just takes applying some mental gravity, but how do you approach less endowed characters? All I can assume is that it takes a degree of subtlety and I have no idea howΒ to start.

Start by studying references. It might be harder to find small breasted models though.

No offense or anything, but by having a tutorial so good about boobies, why the breasts in this drawing are so stiff
π: 0 β©: 2
Because she wears a bra. Probably a push up one.
The point of the tutorial was to show how boobs aren't really how bras make you think they are. Boobs aren't firm and spheric.
But bras are. They shape our boobs and therefore we lose the natural squishy form. That's why they are so useful (appart from the support). Is like putting a water balloon inside of a semi spheric bowl. It's like a shield so they doesn't wiggle when we walk, hurt when we jump or when we are pushed. If you hug a girl and squish her against you you will notice her breasts don't squish as much as you would think, they stay rather solid because of her bra. That way you don't hurt her.
And that's just with normal bras! If boobs don't fill the entire cup, and instead rest over pads, then they spill and create cleavages with round shapes.
But also, notice that some people get sillicone semi spheres inside of their boobs through surgery, making them look unnaturally round and firm. A lot of models and porn stars have this, making people believe that's what's natural (because admit it, you've seen more images of boobs than real life boobs).Β
But as artists, we need to be aware of how things really look like. All the time, we have to study real things and realistic drawings, even if we want to stilyze them later. You need to know how a real pair of breasts looks like, and then you can decide to draw it however you want, as Nsio did here : )

this isn't how boobs work at all. I mean...better than air balloons but boobs aren't like balloons at all. Not like water or air balloons.Β

It is kinda though, specially the 3, 7 and 8 ballon. I have a D cup, and sometimes people have a fun idea on gravity when it comes to breasts. This is really how gravity works on a bigger cup at least, ofcouse they are not like water or air ballons but it is pretty hard to describe. As a woman I canβt find a word that describe specific how they feel, some men do say βwater ballonsβ, but to be honest I think its because of lack of words or experience.

It's a pretty good example though. The bigger the breasts, the heavier they are. Or at least I'd imagine they would be.

A water balloon, which seeks to form a sphere, is a poor model for human breast.Β
The best physical model for breast would be a thick-walled bladder or balloon, filled with a gel, and encased in moderately stiff netting. Real breast are a fat store held up and together by a mesh/web of ligaments (cooper's ligaments). It is the Cooper's ligaments that produce the much beloved "ski jump" curve.Β
Both the adipose (structured fat tissue) and Cooper's ligaments form the breast into an elongated hemispherical shape compressed against the pectoral muscle. Unlike a water balloon, the breast always tries to return to this shape when deformed instead of trying to form a sphere. You can see this in photos of women undergoing mammograms. The breast don't squash out symmetricallyΒ under the pressure of the X-ray plates like a balloon would.Β
The force vectors displayed in the two balloons in the second to last sketch are wrong because the Cooper's ligaments are stronger to the sides than the middle. So, the breast always pull to the bodies centerline. That's why the old bra commercials, "lift and seperates" makes breast look larger, those bras shifted breast out of their natural alignment and to the sides creating the illusion of breast wider breast.Β

gel ballons are Β poor reference for drawing breasts though. I mean it's easier to picture the water ballonΒ or even get one than getting bladder and gel.

`Breasts are water balloons...`
Well, it`s a good way to get started, I guess. Thanks for the simplistic view of the dynamics of...uhmmm...anime-style breasts...?
It helps since it's the only art-style I want...(I don't have an affinity for anything else, so yeah. :/) But this is really a big help. nonetheless.
...Sorry for whatever woman may read this comment... ; - ; Please, I have an idea how real breasts work D:

"Blessed with the privelege"? Nah man, they seriously suck!
But anyways, I like how you explain it. I had a friend who thought that they just stuck in one place and didn't know they were actually squishy objects very much affected by gravity. (Trying to explain it is always awkward -u- )
