It might seem odd that having to stop painting is a good thing. Here's why it is…
The difficulty with landscapes
I've suggested scenic art can be more difficult than other subjects before. This is because there's no definite structure to them. Landscapes can also be complicated, with many elements in view.
A painter chooses what's in still life paintings and what's not. They arrange things, including lighting, to suit their ambition. A painter can simplify a still life subject before they touch a canvas with paint.
None of this is possible with scenic paintings. Digging up a tree to simplify a scene is a bit excessive. Trying to stop the sun moving or playing King Canute attempting to halt a rising tide would be crazy.
Portraits have a natural structure to them. A human being's anatomy is a structure we're all familiar with. Noses centre between two eyes. Heads connect via a neck to the torso. All logical, all easy to see.
Landscapes are both complex and chaotic. Add complexity and chaos together, and you've a lot of problems to solve! (I've discussed the relative difficulty of different subjects elsewhere more fully. I'll put a link in here soon when I've reviewed it).
Difficult is not better
Whether landscapes are more difficult or I just think they are is unimportant. Degree of difficulty does not equate to 'better than'.
I mastered life (figure) drawing at art school. Proficiency with portraits came a few years after leaving.
Still-life was an avid hobby as a child. Buildings and cities were a forte during my illustration years. Landscapes were my last great challenge, and this informs my view rightly or wrongly.
In the end, it's not the difficulty of a process that determines artistic success. An artist's vision, decision making and execution hold the trump card. A poor painting of a landscape, however difficult, is not better than a great still-life. A grand portrait or still-life can be better than a great landscape.
More gazing than glazing
The thing is: I'm a beggar for charging on fuelled by inspiration and an overwhelming urge to paint.
It can be the worst thing to do. I've paid the price of angst and disappointment on many an occasion. If subjects are complex and nuanced, as landscapes are, then it's a recipe for disaster.
Putting the brush down and stopping can be when the art happens. This requires a lot of discipline when creative energy is high.
An oil painter has to work in a structured way. Many of the modern mediums were invented in response to oil's inconveniences. The paint needs to be layered up correctly (fat over lean), for example. I've found my studio paintings need to 'settle' before adding more.
This need for structure encourages a landscape painter into contemplation in the studio. A regular, careful study of a painting in progress has an impact on its success.
Subtle weaknesses created early in an artwork's progress end up biting later. Fine defects have unsubtle and disastrous effects in the finished art.
They'll mean undoing days, even weeks of work. That's if it's even possible, by then, to fix things. Because they're subtle, they go undetected.
Painting with oils has slowed me down, in a beneficial way. This is one of the reasons I prefer painting with oils. I've begun to craft my paintings rather than plough paint on to a canvas. I put more thought into them. Carefully planning art before starting it is not enough. Taking time to check on progress is, in some ways, the more effective.
