The thing is..it IS about lack of skill or rather loss of skills.. skills are and have been lost...very lovely skills..
This is why we have mediocre art and yet we're being told it is fantastic.
It takes years to learn how glazes work. How translucency works. How and why Turner laid down water based paints first and then painted over in oils. It seems that everything learned is gradually being lost...and the art world is doing very little to counter this.
These are skills that are disappearing and we are being left with artists who paint blobs and the world says "wow".
Caravaggio layered up to 60 glazes in a painting. ...the depth of colours in his work is astounding. The light and dark is perfection.
