The Illusion of Depth – Edge, Line, Cast Shadow and Paint Thickness

The Illusion of Depth – Edge, Line, Cast Shadow and Paint Thickness


In this third part of the illusion of depth,
we’ll look at how edges, lines, cast shadows, and paint thickness can be used to add depth
to your drawings and paintings. Hey guys, what’s going on, my name is stan
Prokopenko, you’re watching proko. Lets jump right in and talk about edges. Sharp edges are visually a lot louder than
soft edges and so they tend to pop forward and separate object, whereas soft or blurry
edges recede and bring things closer together. So, a sharp edge between these two object
will separate them. Blurring the edge will somewhat merge them and bring them closer
together. When our eyes focus on something, things further
away or closer to us from that object will be blurred. In photography this is called,
depth of field. When the depth of field is high, sharp details are seen in a very large
range. Objects far away from the focal distance are still sharp. This can seem unnatural because
that’s not really how our eyes see things. Naturally we will see a narrower depth of
field to help us focus on a particular area. A narrower depth of field is a great tool
to add depth to a drawing. Line Line isn’t really a type of edge; sharp, firm,
or soft, but it is a way to indicate the edge of a form. It’s a stylized way that doesn’t
exist in reality, but nonetheless it is a way to indicate depth and can be very effective.
The type of line you use can make or break the illusion of depth. You can vary the thickness
of the line and the value of the line to achieve this. As forms recede back into space use a thinner
line. This is related to perspective, since the objects further away from us will appear
smaller, including the lines. We tend to use the same line throughout the drawing. Sometimes
this might be because of our tools allowing for just one line weight, such as the tip
of a graphite pencil or a ballpoint pen. In that case, you’ll have to go over the line
a few times to make it thicker unlike with a brush or a pencil sharpened to a taper,
where you can vary the angle to change the line thickness. Also, consider varying the
value of the line. Make the objects further back lighter and the ones that you want to
pop forward darker. This is related to atmospheric perspective that I talked about in part 1. Line can be used not only in separate objects,
but within an object as it recedes or where there is overlapping form. Such as in the figure. This tricep is closer
to us than the deltoid. But, I want to show that the edge of the tricep is wrapping around
and behind the deltoid. So, instead of using the same line in the overlap, which is still
effective because of the overlap, I could use line weight to make it even more effective.
I could make the line thicker in the areas that are closer and thin out and lighten the
line of the tricep as it wraps around the deltoid. Cast Shadows Cast Shadows are another way you can show
that something is in front of something else, especially when there is no overlap to do
that. In fact this is heavily used in graphic design to pop things forward. Photoshop and
other similar programs have a “drop shadow” option that immediately pops a shape out from
the background. In this figure drawing the cast shadow helps
to bring the arm away from the body. And suggests that its further away at the elbow because
of the greater distance to the edge of the cast shadow. A cast shadow on a ground surface can indicate
that there is open space behind the object and also can serve as a great way to add converging
lines to add some perspective to a scene. Paint Thickness The final thing I want to mention is quite
literally adding depth to a picture. If you’re using paint, you can physically bring something
forward by using thicker paint on that area. I won’t go not too much detail about it, but
I think it’s easy concept to grasp. If you have two objects, using thicker paint in the
distant one might not be a good idea. But thicker paint in closer objects can serve
as a great attribute for depth. Just an idea.. Ultimately creating the illusion of depth
in your artwork will be achieved through a combination of the concept I went over in
the last 3 videos, and its up to you to decide which ones you want to use and how you want
to use them. It depends on your style. If you’re a beginner, try all of them and don’t
worry too much about style. As you develop, your taste will grow and change, and your
style will come naturally. Ok, that’s the end of the series, hope you

best way of doing that is by getting my Portrait Fundamentals DVD. The difference between the
dvd and the free videos online is, there�s two additional real time demos at an hour
and a half each. And it�s available as a digital download so you don’t need internet
access to watch the lessons. Thank you! buh-bye

  1. One Ring to rule them all, One Ring to find them,
    One Ring to bring them all and in the darkness bind them
    In the Land of Mordor where the Shadows lie.

  2. You should make a video series for kids. I've been using some of your videos with my elementary school art classes, but I can't use all of them 'cause of the nude models.

  3. Great stuff, these videos refresh some things that i forget or give new ideas to try out. Simple clear and inspiring.

  4. Hey now Stan, drop shadows are used heavily by amateur designers. Experienced ones avoid using it cause its a cheap and tacky looking effect.

  5. I get way too excited when I notice a new Proko video. Thanks for making these! They always inspire me to get out of my comfort zone and try some new techniques.

  6. Excelente fuente de información. Muchas gracias por compartir tus conocimientos con todas las personas autodiactas .

  7. Don't forget about us when you get famous haha! Your channel is growing at an astronomical rate! Great work Stan!

  8. You are an animal, I love your videos. I already know most of this, but I have to go it you, you never made a mistake or said anything that isn't true in any of your videos. You really know what you are doing, unlike a lot of overly confident YouTube channels.

  9. i am confused. Lighter in the background , darker in the foreground? I was thinking saturation should decrease, not so much value??

  10. Think of most of the drawing videos on YouTube as community colleges. Proko's videos are like Harvard U. So informative with a great mixture of theory, practical examples, visuals, and humor!
