A certain illusion

"Midsummer Pure Land" watercolor、F6

I tried making a demonstration in the classroom.。If you look at it as a photo、Notice that "vertical" is quite tilted.。Looking at the work again、I don't feel it as much as this photo、It was clear that the vertical line was tilted to the right.。

post-impressionist painter、Cezanne's vertical line is also tilted by about 10 degrees.。I have never seen an art book that points this out.、I think it's a sensual "habit".。Cezanne's “10 degrees”、against the vertical line、Because they are all tilted at the same angle、I thought it was a habit, but、in my case、If you look closely, it appears to be somewhat radially open.。In other words、This is not a habit、I think it's an "illusion" caused by something.。

level、vertically、I felt like I should have had absolute confidence.、I can't help but feel the fluctuation。What is the reason?。Is it because my eyesight is getting worse?、Is it because my senses have become dull?、Is it because my field of view has become narrower and I have become lazy about comparisons?、and so on。

Probably not the only reason、Perhaps an "illusion" is occurring due to multiple overlaps.。Fair enough。I realized that this kind of thing is starting to happen to me too.、Let's be aware。
