Join Value Challenge 2: Scale


There are many paths to drawing mastery.

If you want realism in your work, you need to master seeing values and controlling your medium. That’s what the Value Challenges are all about. This is how I train artists from all over the world at Barcelona Academy of Art.

Join the challenges and become a more sensitive and skillful artist:

Why a Value Scale?

Somebody might have already told you to make a Value Scale. Perhaps you got excited about it and genuinely wanted to do it. But maybe you thought “I don’t know where to start”, or “that’s boring, and a waste of time”. Well, I think if you do this even once, it will save you hundreds of hours.

Consider all the images you are going to make in the coming years: portraits, landscapes, concept art… You’ll realize that values are at the core of every one of them. If you have to guess your way around values, that is the real waste of time.

I recommend doing at least one Value Scale for every medium you work in. The ideal moment is when you first encounter a new medium, but many experienced artists still practice with Value Scales to keep their eyes sharp. If it’s good enough for them, it’s surely good enough for us!

Here is my invitation to you to take on the Value Scale challenge. Ready? Let’s do this.

How to make a Value Scale

A) Gather materials

  • A soft pencil (I like a 2B)
  • A hard pencil (2h works well for me)
  • A kneadable eraser (if you can’t find one, work more slowly and carefully)
  • A ruler (you can also use the edge of a book)
  • A piece of paper (sketch paper will do, but the nicer the paper the better)

B) Things to keep in mind

  • Working carefully and with clean hands you will finish much quicker than trying to rush.
  • Keep the tones very smooth (free of texture/noise) so you can see the value identity of each step.
  • When it’s finished, the contrast between all steps must be evenly distributed.

1) Draw the scale

Use light lines. Make 9 steps. If this is your very first Value Scale, you can do one with 5 steps.

9 swatches pre-drawn cleanly.

2) Begin with the extremes

The most common mistake I see is students trying to make a Value Scale “from left to right”.
You will get much better results by starting with the ends of the spectrum: 1 and 9.
Go as dark as your pencil allows on 1 and leave 9 empty (just the paper).

Starting with the extremes: 1 and 9.

3) Find the center

Add the missing tone in the middle: 5. It won’t be perfect, but get as close as you can. Keep the tone even!

Adding the missing tone in the middle: 5

4) Find the center again

Add the missing tones in the middle: 3 and 7. Adjust 5 if you need to.

Again, adding the missing tones in the middle: 3 and 7

5) Add the final tones

Add 2, 4, 6, 8 to complete the scale.


6) Rebalance

Finish the scale by evening it out where necessary. A very effective strategy is to identify the biggest “jump” between two tones. Here that was between 6 and 7. I darkened 7 slightly, lightened 4 a bit, and made 5 more even. Done!
