I dislike the word "cheating" which invariably comes up in regard to tracing, as it is emotionally-laden and tends to cause heat rather than light to be generated on the subject

My opinion is that it depends very much on how it is used. (Let me set the scene first, with my answer - it
does eventually come back round to tracing, I promise

)
The problemsI think one problem that is seen often in beginners (and sometimes not-so-beginners, too) drawing freehand is difficulty in proportions, so that - with a portrait for example - the individual features are drawn well, but the
relationship or scaling of these
to each other is off - so that the top of the head is in the wrong place relative to the face, for example, or the mouth is too low and too small, etc...
Now I'd suggest this occurs because the artist has been concentrating on the detail, and ignoring the "big picture" - I think the tendency is to narrowly focus in on the exact place that the tip of the pencil is hitting the paper, like tunnel-vision on the pointy tip of the pencil - and one tends to see people who do this holding the pencil near its tip, and bent over the drawing like they were signing a cheque.
Another problem often seen is that the lengths or angles of lines are off, or that the edge of a face is reduced to a single inaccurate arcing curve.
Gridding?One thing that's often suggested as a workaround for both sets of problems is gridding - so that a grid is drawn on the ref-photo, and a matching one on the drawing, and the artist then concentrates on trying to accurately put in the lines of the drawing one-square-at-a-time. This can work, but it really ducks the issue, because it
reinforces the idea that one must concentrate on the small detail, and provides a way that the artist can get the different areas in the correct relative sizing and proportion
without having to think about it at all, or even
recognise the true nature of the problem (namely the "tunnel-vision" approach).
Why tracing gets a bad reputationTracing is often condemned as "cheating" because again it
can be used in an
uninformed way, where the artist is focussed down very tightly on an area of the drawing just 3 or 4 millimetres square, and is wholly concentrating on trying to make sure that the pencil doesn't wander off the underlying line on the original image. Now I'd agree that
this approach to tracing
is bad, because again it doesn't address the real problem, which is the mistaken belief that its all about focussing in very tightly on the location where the pencil-tip hits the page, and then crawling along the line like a frightened tightrope-walker. This sort of
attitude to tracing gets the placements, relationships and proportions right, but it teaches
nothing about how to do so
without a piece of tracing-paper - and thus tracing gets a bad name, and is called "cheating".
But....How can we get placements, proportions. and relationships right?I think the key concept is that we have to
think big - and see big - what I mean by this is that we need to get away from the idea that we have to focus in on the exact pointy tip of the pencil. How can we do this? There are working approaches which
immediately help with this:
1. instead of working on a tabletop crouched over our drawing, put the paper onto a board, and prop it up
near-vertically. A painters easel is the ideal thing here (
that's what its for, why it was invented in the first place) - but if you don't have one, any arrangement where you can prop it up will do - tape it up to a smooth wall, for example.
2. get back
away from the surface, work at arm's length - ideally, do it standing up.
3. hold your pencil at the
back, and
lightly, not tightly at the tip. Hold your pencil like an orchestral conductor holds his baton.
Now you're ready to do a drawing, at a reasonable size (another mistake beginners make - "I'm only a beginner, not a proper artist - so I should be humble and draw it small, so that I don't waste materials, or look like a pretentious showoff, posing at an easel"

).
How do people do it without tracing?Now, if we break down what we see - either in a ref-drawing - or even from life! - into a set of straight line-segments first - keep back from the paper, draw holding the pencil at the back, lightly - draw a rapid line, moving from the shoulder and the elbow rather than the wrist (think of that conductor in front of his orchestra). Look at the line you've made, compare it with your reference - is it accurate? Should it be longer or shorter? is it at the correct angle from vertical?. If not, put down a corrected line, check again (rub out the wrong one - erasing isn't "cheating" either!).
As you go, keep checking out how the lines relate to each other, and also check out the sizes and shapes of the spaces they make or enclose. Don't think in terms of features - "eye", nose", and so on, but just in terms of lines of edges you can see - including edges of shadows - and the areas they enclose. Try to break down what you see into abstract shapes, and look for big shapes first, then gradually refine these into smaller shapes. Keep standing well back - occasionally check how you are doing by standing several paces back and taking in the over-all view. Check it in a mirror, too. Realise that (even
lots of) time spent getting the big proportions and placements correct is time well-spent. Drawing is
not only about doing the shading - and it isn't about speed, either. The winner is the
best drawing, not the fastest.
Oh dear, that all sounds a bit advanced to me, I thought this was supposed to be about tracing?Lets learn how to do most of these things, but
using tracing to help us,
and learn at the same time! If you can, set up as I've described above, on an easel. If you can't, get your drawing board on a desktop or in your lap, but try to put as much distance between it and your head as you can. Put your ref-image down on the board, and fix it securely, with a piece of tracing-paper on top.
Start by finding three or four points on the ref-image, preferably towards the edges, where you can make dots or crosses for alignment (You can make these yourself on the original ref-photo, if there isn't anything suitable) - the idea of this is that it fixes the alignment of the ref and the tracing - so that if the tracing-paper gets moved, you can easily get it back into the right place.
So, can tracing be a learning tool?Now, holding the pencil towards the back, and keeping back as far as you can from the board, start tracing - BUT
do so thinking of the overall shape of the line you are on - NOT focussed onto the point of the pencil.
DON'T worry about staying
exactly on the line, but instead think about
travelling along the line and getting the
direction and
distance correct.
Use the tracing to help you get the
line-lengths right, and the
angles, and the
sizes and
shapes of the areas. Remember not to crouch over the drawing. Keep back, hold your pencil at the back end, draw like you're conducting an orchestra, make the lines in rapid smooth movements, with a light touch.
As you are drawing lines or curves, note how your arm
feels as you move it rapidly along the correct line - relate the
feel of the movement to the
visual feedback you are getting from seeing where your tracing-line is in relation to your ref-photo underneath.
Feel how drawing a rapid but accurate line is different from either "tightrope-walking" along the line,
or from drawing a generic arc.
Used like this, tracing can, I believe, not only get the drawing done - but also be a tool which can help you how to learn to draw accurately
without tracing.
