Hello my friends and welcome to another Tuesday of tutorial!
I am Leonardo Pereznieto and I am so happy because today, my brand new book,
on the "Basics of Drawing, the Ultimate Guide for Beginners" gets released to the public!
You can get it today from Amazon, and very soon from all major U.S. bookstores.
I worked from about two years on this project.
Bring all the fundamentals of drawing, in a very simple form
to you.
And today we will pick from Chapter 10 which is about
surfaces and textures... ¨How to draw glass¨.
Specifically how to draw marbles.
When light hits a transparent object, it behaves like this:
Let´s say that the illumination is coming from the top left.
The area on that top left of the object,
tends to be a little bit darker, except for a small bright reflection.
Because the light will come through the object, and hit the opposite side,
which will be lighter.
It will create a shadow that often will be darker close to it and then get lighter,
and within that shadow, there may be a refraction, a distorted light on the surface.
Good! To draw our marbles I will use a Tutto3 Mechanical Pencil, on gray-toned paper.
And to make them perfectly round, let's use a lid or a circular object or a compass.
In this case the source of light will be above and behind the object,
so we will have a bright spot on the top
and I´ll mark a few others.
As I said, this area facing the light source will be darker
but not too dark since it is transparent,
and it lightens as it goes lower.
Some marbles have a nice shape inside, made by twisted paint.
So let's draw that!
With a white pencil we draw the top reflection
and the lower area which I will finish in a little bit.
With a stump we can soften and make more even,
the shading.
This lower area as we know gets illuminated
but maybe a little bit less intensely,
than the top bright spot.
We will have the cast shadow here, with an illuminated area.
And I switch to a softer lead for the darks.
By the object, the shadow will be darker.
And then it lightens and get softer.
Of course, everything that I am telling you is just a guideline,
is a very general rule
it can change tremendously depending on the type of illumination,
how far the light is, how strong, how intense or diffused
and how transparent the object is, as well as its texture.
And let's smooth out the shadow.
The shape of the illumination on the surface, may be like a water drop or just a little dot,
or it may have a strange shape like a hairy monster for example [laughter],
because of refraction.
Very good! ¡excelente!
And let's draw two more marbles.
We will draw this basically in the same way,
and I´ll just give them a few variations.
Of course, I can use the white pencil like this for the lights, because I´m drawing on toned paper.
If I were drawing on white paper,
I will leave that white for the lighter values.
Inside let's draw a different shape,
and in a different direction.
If you make additional highlight reflections,
remember to follow the shape of the surface of the object.
And now, let's draw the 3rd. sphere, the 3rd. marble.
And tell me, did you use to play marbles when you were a little kid?
I did!
We do the shadow,
and again, you can see the degradation of value from darker on top of the sphere,
going lighter toward the bottom,
and with the lower part illuminated as hit by the light.
In this case on the 3rd. marble I am adding a darker area toward the bottom
as if it were reflecting something.
As you saw I'm mainly using a kneaded eraser,
when I need to lighten or erase an area with graphite.
The list with all the materials that I am using,
is in the description below the video.
If you made it all the way to this point, I would love to know it!
Please in the comments write me the secret code:
"Don´t lose your marbles" [laughter].
We give it the last touches...
and it´s ready!
If you enjoyed it, please give it a LIKE!, subscribe to Fine Art-Tips,
if you haven't done so already,
get my book with the link below [laughter],
and I will see you with more creations,
on Tuesday ;)
