In this episode , we go extreme extreme angles are usually challenging for people and frequently ignored by artists .
But studying the extreme angles will make you better at the more common angles because you'll have a better understanding of the method to help us visualize the extreme angles .
We have a special guest .
This is looming .
Let's start by talking about the twist or rotation along the z axis .
This has a few important effects on the head .
First , the center line and brow line will be at an angle .
Second , the side plane will go down to reveal more of the top of the head or up to reveal more of the bottom .
The ellipse that indicates the side plane will be angled perpendicular to the brow line .
This is caused by the ellipse being in perspective to get the proper angles on the front and side planes .
Remember that the head can be simplified into a box to visualize the perspective .
You can see the same angles throughout the face as on the box .
So this is what we have so far , the hard part is over .
If you do that part , right , adding the jaw should be fairly straightforward .
Just observe the major plane changes .
The third effect a twist has is on the gesture of the neck .
Look for the curve , try to avoid lollipop necks .
The concept of stretch and pinch applies here too .
Now , let's take a look at extreme up and down tilts along the x axis .
I always look for the degree of the tilt by observing the angle from ear to brow , find the angle of the brows .
And then the thirds remember what we learned in part two of the series about foreshortening , the thirds will get smaller as they receive from us .
So in an up tilt , the bottom third will be about the same as half of the side plane and the forehead will be fairly small and the opposite in a down tilt , a confusing area for most people is the shape of the jaw .
As the head rotates up and down .
During this rotation , the relationship of the corners of the jaw and the bottom of the chin will change .
As a person looks up , the chin will come up and at one point be in line with the jaw , creating a boxy shape .
If you keep going the shape actually inverts and you get the opposite triangle in an up tilt , you're also seeing the bottom plane of the jaw which wraps around the cylindrical neck .
This connection of the jaw to the neck is important .
So try not to overlook it .
As a person looks down , the jaw shape becomes more triangular because the corners of the jaw and the bottom of the chin move away from each other .
Another common area of frustration is the tip of the nose in an extreme uptil the tip will be unusually close to the eyes .
It's so unusual that most of us feel like we need to move it down to lengthen nose , observe the shape of the bottom plane of the nose and compare it to the length of the entire middle third from brow to bottom of the nose .
It's important to remember that the eyes and lips are not flat on the face .
They are rounded in their simplest forms .
So observe the curvature of these features as they wrap around the eyeball and the tooth cylinder .
So what would happen if instead of the head rotating up or down , we move the camera above or below the head .
When this happens , the side plane rises or drop to reveal more of the top of the head or the bottom of the head .
But this time without changing the angle of the center line , since there is no twist from this angle , the neck will be mostly covered by the head and we just see shoulder .
That's it .
For this episode .
Next week , we'll be covering the eyes .
I decided to do a little giveaway to help promote this video .
The prize is your very own loy .
The one I use for this video .
Actually , I posted a link to this video on my Facebook .
All you have to do to get your own loy is find my profile on Facebook and reha that post .
I will use a random generator to pick the winner on September 14th .
Good luck .
