win! I probably would've darkened the area at the far left. do you squint while you paint? not just from life but from imagination as well it helps to know how you want your values to be when you reach a stalemate. keep going bro!!
hmm not blur bro, squint. 'Blurring' your vision is good in seeing the basic chroma and/or hue in objects rather than all the subtle changes in hue. for example when you look at grass in a field or when you are on a high roof look at the vast cityscape, your eye is overwhelmed by all the small additions of colour, blurring will chop away all those little additions and show you the basic colours in the scene that you can probably start with. i suppose it is good for Values as well as you are only able to the colour you are observing in it's basic state. it's good you can do it at command, I've met a few people who can't.
squinting on the other hand, chops away all the the subtle changes in value. blurring my vision I've not really used for imaginary sketching as I start with basic colours to begin with squinting on the other hand helps me in knowing if I've probably made something too light or darker than I intended from the vision in my mind. you just see it "that's not how I wanted it"
sorry If I've spammed you with stuff you already know, when you mentioned blurring and saying you can do it on command it made me think you thought I meant differently to what I said. everyone should know how to squint as it's just lowering your eye lids like as if the sun is in your eyes. blurring on the otherhand is the unique one as you implied haha
I use to think I was the only one who could do it. Some sort of special power or something. I learned at a young age that not everyone could do it. I didn't actually know there were others until about 6 months ago when I came across something like this: [link]. It wasn't that url I don't think, but it was interesting nevertheless.
I use it when I paint, but prolonged use hurts my eyes.
