So the fat over lean rule, I know, exists because if you don't use that rule, the layers underneath will dry faster than the newest layers and cause the painting to crack.
I'm a bit confused about it though.
- Does this mean that if you wait for the paint to dry between layers, you can ignore this rule?
- But if you don't wait for the paint to dry, then surely you wouldn't need to add more oil because you'd be painting wet on wet and everything would dry the same rate anyway? As long as you don't reduce the amount of extra oil you use, I mean?
Obviously this rule exists for a reason or artists wouldn't have been following it for centuries, I just don't completely understand it and I'd appreciate it if someone could take a moment to explain.
Sorry if this is a stupid question, I'm obviously new to oil painting.
