Art Education: The Dreyfus Model

Hello everyone I’m Taber, Vice President of Animation Resources. I’m going to be making a series of posts focused on the more academic side of artistic instruction and learning in general. This sort of information can be helpful to both teachers and students as you push yourself to improve and practice your discipline.

Preston Blair instruction

As a beginning artist it can often be difficult to objectively judge your own progress or the quality of your own work. Being able to place yourself in an accurate position of skillfulness can help you to recognize your past growth and current deficiencies so you can better target areas for improvement. But what if you can’t tell exactly what the differences are between your work and the work of more highly skilled artists?

The Dreyfus model focuses on work practices and approaches as a measure of skill acquisition. This can be helpful to both students and instructors as it tends to be entirely non-judgmental and easy to identify objectively. The model uses four qualities to determine work habits:

  • Recollection (non-situational or situational)
  • Recognition (decomposed or holistic)
  • Decision (analytical or intuitive)
  • Awareness (monitoring or absorbed)

These attributes stack one at a time to provide a framework for evaluation:

For an accurate measurement, ask yourself these questions regarding the above attributes. Because some of these attributes can flip between a more advanced and a less advanced state, I recommend relying on the lower state. For an example if you were trying to decide if you are an intuitive decision maker, or a rational decision maker but you do both part of the time, put yourself down as rational as a rule of thumb.

  1. When you recall knowledge about the subject, is it always in a related context with other information, or is it sometimes rote memorization?
  2. While thinking about an aspect of the subject, can you clearly distinguish between relevant and irrelevant aspects of the work, or is it sometimes difficult to tell what’s important?
  3. When planning your own work, do you need to carefully and analytically lay out the steps beforehand or can you see the entire project as a whole task?
  4. When making decisions in your work, do you have to do any problem solving, or do the answers come to you intuitively, without effort most of the time?

Once you’ve answered these four questions, find the lowest tier which corresponds to your answers, even if you choose an attribute from a higher tier. Read the Needs column from the above chart and try to focus your learning on the types of practice listed in that section. Don’t cheat yourself by practicing projects which are too complex or unstructured! That sort of practice is really only for very highly skillful artists.

This system is similar to the surface to core concept illustrated by Scott McCloud in his book Understanding Comics which I highly recommend! In the book, McCloud describes how a person who is initially drawn to be a fan of an art-form must undertake a journey to the core of that medium before being able to master and thus give back to that medium.mccloud_understanding_comics

Additionally, this same artist’s journey from surface to core is echoed in much of the advice and instructional material given to artists throughout time, from Zim to Richard Williams. In essence, this is what an “old masters” approach is. This struggle is ultimately the best way to gain skill in an artistic medium, however it is difficult and it does take time.

“Nobody tells this to people who are beginners, I wish someone told me. All of us who do creative work, we get into it because we have good taste. But there is this gap. For the first couple years you make stuff, it’s just not that good. It’s trying to be good, it has potential, but it’s not. But your taste, the thing that got you into the game, is still killer. And your taste is why your work disappoints you. A lot of people never get past this phase, they quit. Most people I know who do interesting, creative work went through years of this. We know our work doesn’t have this special thing that we want it to have. We all go through this. And if you are just starting out or you are still in this phase, you gotta know its normal and the most important thing you can do is do a lot of work. Put yourself on a deadline so that every week you will finish one story. It is only by going through a volume of work that you will close that gap, and your work will be as good as your ambitions. And I took longer to figure out how to do this than anyone I’ve ever met. It’s gonna take awhile. It’s normal to take awhile. You’ve just gotta fight your way through.” -Ira Glass

I have some personal theories about the types of artistic practice activities which benefit artists the most when trying to improve aspects of their work, and I’ll be talking about that next time!


Right now, it’s Back To School time at Animation Resources, and for the next two weeks we will be sharing reasons why students and educators should be a member of our important project.

Instruction: Animation Reference

Muybridge_race_horse_gallop

Muybridge – Horse Gallop

Today I’m going to be showing everyone my planning process for using photographic reference to plan and execute a naturalistic horse run cycle. This process has been used by generations of artists to help analyse and capture the motion patterns of real-world objects and creatures. This type of study is invaluable for building an internal “motion library” in your mind, so that when you have to make guesses about how something impossible might move, those guesses can be as educated as possible. For the beginning animator, doing motion analysis can also help give a stronger sense of what motion details matter, and which are best to remove to get an optimal stylistic motion.

First up, here is the finished animation: Horse_gallop

In a complex cycle like a horse gallop, there are many things to understand, and without experience animating similar creatures it would be difficult to plan ahead for this animation considering that we have so much to keep track of.

Get Video Reference

If you can film your own reference, then that’s a great first step, but if you can’t, the first place I search is the BBC Motion Library at Getty Images. This collection has thousands of real-time and slow-motion shots of sports, nature, vehicles, and much more. It’s free to view and download, which is ideal as we will need to carefully go through our shot frame by frame in order to analyse it.

Here is the shot I used for reference. As stated above, it’s free to download (non-commercial use of course) by right clicking the clip and choosing Save as.

A few notes about the shot:

  • It is playing in real-time, not slow motion, so we can use it for timing information
  • The shot isn’t stabilized, so we can’t use it to track body parts necessarily
  • The whole body is visible, including the feet as they touch the ground
  • The speed of the run is relatively stable for a few seconds, ideal for a cycle

Use A Frame by Frame Video Software

Next we need to be able to see each frame of the video one at a time. You can do this by importing the footage into any video editing software if you  have it. I prefer to use a much simpler method by opening it in QuickTime.

quicktime

QuickTime interface

To my knowledge, QuickTime is the only freely available video software which allows you to step through a video one frame at a time (using the left and right arrow keys). Many others allow you to skip several frames, but none that I’ve found allow this level of precision. Another benefit of this software shown above, is the ability to switch the timecode to frames, so we can easily count and locate keyframes in our action.

Before using the shot for any timing information, you’ll need to know the frame rate of the video. I figure this out by going to 1 second in the timecode, the switching to frames to see how many have elapsed. This shot is in a standard 25fps for european PAL broadcast. This will effect our conversion to our frame rate. In my case, I’ll be animating at 24fps (see the conversion math later on at the bottom of my Xsheet).

Get Additional Reference

Although we could use a single source of reference, it’s better to have several similar sources to draw from, and the plates from Edward Muybridge’s animal studies have been a source of inspiration to animators for a century. We have an extensive library of Muybridge here. These images (shown at top) are invaluable because they show a flat sideways perspective of a horse galloping with extracted frames to display the entire cycle of motion. The only problem with this is that we don’t know how fast it should be moving, a problem we’ve already addressed with our video reference.

Here is a playback of the muybridge_horse set to a realistic 40fps.

By comparing the frames to our video, I determined that the approximate speed of the original Muybridge shot was a brisk 40fps. I also adjusted the frames to stabilize the ground, put vertical and horizontal lines in to help track key parts of the body, and finally tracked each hoof with a colored ball. All of this information provides almost everything we need to put together our plan.

Horse Gaits

The last bit of information we need is an understanding of the pattern we hope to find and reproduce. This information I found easily on an equestrian website, along with footfall patterns of all the primary horse locomotion speeds.

Record Observations and Refine

Finally we are ready to utilize all of this information into a formal plan for animating our horse. By stepping through the video and referring to the Muybridge plates, I record all of the pertinent information I can onto an Xsheet.

xsheet3D_Horse_Gallop-1

Modified Xsheet for planning CG animation

By examining the sheet above, you can see that I’ve sought out the most important aspects of the motion and spaced them out in time so that they flow fluidly. Here is a list of the things you should look for before continuing:

  • Key Frames – These should be the most informational single images for the action, without which, none of the remaining actions can possibly hope to illustrate the action properly. In my case, I chose the Squashed mid-air position, and the Stretched leaping position of the horse.
  • Extremes -The foot contacts must all be present, as well as the maximum and minimum vertical positions of the chest and flank.
  • Breakdowns – Wherever necessary, plan for the passing or half-way positions of body parts and poses, so you do not miss the nuance of the motion pattern.
  • Small patterns– Note the path and notes about the head, these patterns are important and shouldn’t be missed. Make notes of any details you might easily forget later.

For one reason or another, the use of Xsheets has never fully translated over to computer animation, which I think is a major loss. Although these sheets were originally used to plan for the exposure of cell levels in traditional animation, they can find a valuable second life in helping to plan body part motions and musical timing.

Execute Plan

With all of this preparatory work, the only thing left to do is to use this roadmap to complete your animation. By this point, you should have such a solid idea of what your animation is going to look like, that the actual work of animation is almost an afterthought. In The Illusion of Life, as well as The Animator’s Survival Kit, the authors tell stories of their lengthy and strenuous planning procedures, and how once planned out, an animation scene was practically complete before pencil ever touched page. This method allows you to keep a solid focus on your scene even between work sessions, and frees you to focus on the details without becoming lost in the larger patterns of motion.

Art Education: Practice Types

Last time we talked about how to objectively judge a person’s current ability within a discipline using the Dreyfus Model. Today I’ll be giving my personal theory about what types of practice are best for students and professionals of various levels, and how to determine what type of practice is right for you.

I formed this theory by combining my own experiences learning sports, art, music, and mathematics with advice given by notable teachers of animation and art. My litmus test has been that I must be able to apply these practice methods to any subject a person might want to learn, although practicing skills is this system’s focus, not academic memorization.

The five categories I’ve identified are listed below with a short description of each and an example of the type of activity you might engage in if your goal was to learn how to draw. Remember that these are broad categories however, and may be applied to any skill or discipline.

Willy Pogany’s Life Drawing Lessons

Academic

When first approaching a subject, the concepts and working methods are all completely new, therefore the first and most basic type of practice is the type which is most widely used in the classroom: Academic practice. This would include all newly introduced or researched information which comes from an authoritative source such as a textbook, tutorial, lecture, or guide.

This type of practice is most helpful right at the beginning of a student’s study. If you find that general knowledge about the way your discipline works is absent, or that parts of the working methods of your skill are hazy or poorly understood, this is the type of practice you should engage in first. However, as soon as a workable understanding of the concepts is obtained Academic practice should be abandoned in favor of a different type to allow the student to internalize what they’ve learned.

In drawing this would be the equivalent of learning body proportions and anatomy. These are very critical and useful areas of study, but if that’s all you practice, your work can only ever look like a textbook illustration.

Public Sketching – Gordon Grant

Drilling

In order to become a confident and skillful practitioner, a student must commit to hours of practical application. In sports all minute aspects of the game are drilled endlessly until each action becomes as natural as breathing. In music, scales and rhythm exercises are used as warm-ups even by highly accomplished musicians so that they become second nature. Drilling is any task which you already know how to do, and can perform repeatedly in small rapid bursts.

This type of practice is the next most common type of activity employed by students and professionals. In essence, the purpose of drilling is to gain confidence and familiarity with your working methods. A pleasant byproduct of drilling is an increase in speed and a decrease in error making. Many professionals if not most of them continue using drilling throughout their careers as a way to keep sharp.

Drilling in illustration would represent public sketching, thumb-nailing compositions, or plein air painting just to name a few.

William Lee Hankey

Quality Test

At the point where a student believes they have learned enough to become competent, it may be time to put all of their acquired skills into practice by attempting to perform their discipline to the best of their ability. In sports, this would be game day, in music it would be the concert or recital, and in art, this would represent a single piece of artwork meant to  showcase the artist’s talents.

Art made for a quality test should be made carefully, slowly and deliberately. No time limit should be imposed and the artist should be as thorough and careful as they can possibly be in order to push the limits of their ability to the extreme.

Performing work of this type may often have humbling results, revealing exactly what shortcomings the student has yet to overcome. As a diagnostic tool, this type of practice is invaluable, and also provides milestones for the student as they progress so that they can compare their current work to their past work.

Quality illustrations should  make up much of a student’s portfolio along with life drawings.

Gustaf Tenggren Comparison

Experimental

After mastering the basics through the use of Academic and Drilling practice, it becomes necessary for a student to explore their own preferred methods and to attempt to expand their ability beyond what can be taught to them explicitly. Experimental practice is done to attempt to create a new work method or a unique result which is entirely the student’s own. It is important to note that this type of practice is most useful in the hands of an already skilled practitioner of their craft, but it may be useful to novices as well, as a method of discovery.

In my opinion, this is where many graduate students and professionals fail to expand their abilities. It’s very easy to copy and reproduce from textbooks, instructors, and tutorials, but it’s a very different and altogether more frightening thing to try to create a new method of working, or a new way of seeing the world.

In illustration and art in general, those artist who are synonymous with a particular style or artistic movement likely owe their success at least partially to experimental practice. The need to perform this type of practice need not be that grand however, as even small modifications to an artist’s working methods help to personalize and internalize their craft.

Albert Hurter

Freeform

The last form of practice is the free and non-structured kind which children indulge in. Although non-academic and not strictly intended to improve a practitioner’s ability, freeform practice serves as a crucial way for the student to enjoy themselves with their chosen craft. Although it may seem unnecessary to list it here, I believe that maintaining a fun and creative attitude toward your work is at least as important as academic study, if not more so.

Work of this type has one goal: to make you happy. After all, why are you putting in all of this time becoming skillful if not to use that skill in a way which pleases you? Very often unfortunately it seems that the mark of a professional artist is that they draw at work but not at home, having long since ceased to enjoy what it is they do for a living. Don’t fall into the trap of slowly choking the life out of your art, have a little fun now and then!

I hope these practice methods are helpful to you or your students. Next time I’ll be talking about motivation and forming a practice habit!
