The pen control exercise is a start. It teaches you how to be precise with your lines and the pressure exercise teaches how to control the thickness of the line .
It looks like this:
You can find it in the Art School Term 1 - Assignments.zip under "Photoshop for Digital Production 1"
I used to do this everytime as a warm-up.
I'm gonna link you a couple of videos which explain why you even use line weight at certain spots:
First Scott Robertson, extremely skilled in his job and he also has books which are quite difficult to grasp for beginners, so I would wait a little.
This is a website which is useful for a quick recap:
Lesson 7: Introduction to Line Quality
About learning it:
- You can start with simple forms like cubes and cylinders, depending on what you want the line to convey you might have to add forms behind one another to see an effect.
- Traditional is almost the same as digital, try to be consistent with the lines and experiment a lot, back in drawabox we had a technique called ghosting, it's basically this:
- You want to draw a line.
- Try to imagine the line where you want it to be.
- Now, hover with you pen over the imagined spot and do the hand motion but without actually touching the paper, you do this motion till you really feel confident about putting the line down.
- Once you are ready you lower the pen onto the paper and do a quick but confident line.
