As of right now it's 6:10 AM.
I opened the window and observed the outside.
There is a barn here with a metal roof.
I noticed many interesting things.
When observing something under weak lighting conditions many of our color receptors don't function properly (or maybe don't activate at all. I'm no expert on this.)
The cells which are responsible for distinguishing light from dark are always active though. (Again, don't quote me on that.)
They are scattered all over out retinas.
I noticed a dotted pattern in the shadows. (That's nothing new in an on itself, but I became more aware of that fact and that I could integrate it in my art.
The dots are noticeable. I mean, it's noise, but not the kind of noise you could emulate with a noise layer in Krita. The dots and patches are slightly bigger.
Also the roof that I know has a hard edge in bright sunlight, had a fuzzy edge.
Not a blurred effect that you could achieve with a gaussian blur, no.
It was broken up. It kind of had something of a fata morgana. Maybe, because the air in my room was relatively warm in comparison to the cold outside night air?
I think I could replicate that effect digitally with a smudge brush that is not round, but has some notice angles and uses a bit of texture. (I recently played around with such a smudge brush, so I got the idea of using that while looking out of my window and trying to figure out a way of replicating what I see.)
Then I went into the other room, where a mouse trap lies on the floor. I knew where it was lying, but coming from a room where I turned on bright lights and stepping into a room without, it took a noticable amount of time for my eyes to adjust and to be able to observe the mouse trap on the dark carpet.
First I didn't see anything except gray noise, then the trap started to slowly fade into vision, still just a fuzzy shadow shape of more or less a single value (besides the dotted shadow pattern).
After around what felt like two second, I was able to discern a light and a shadow side of the flat quboid shape.
The relatec pic is trying to emulate what I saw.
The picture uses two noise layers as visual enhancements. One simple noise layer like tumbler artists use it. (I've slightly blurred the noise, reduced it's saturation and lowered the opacity.)
The second noise layer has bigger specs and is rougher.
I created it the following way:
- create new layer filled with blank color and apply random noise
- apply a gaussian blur (10px in both axis)
- add oil paint filter with a stroke width of 6 (Krita, very GPU straining, result will look almost like a flat tone)
- then apply an auto contrast filter
- set the layer to multiply
- play around with the opacity and a layer mask (I used a white transparency mask with a 10% gray in areas where the light hit. That makes the pattern very faint in those areas. I didn't want to completely get rid of it. It should still be very, but very subte. Not noticable, if you are not deliberately looking for it.)
You might say it looks good, but only because you don't know what I was aiming for.
If you are pushing yourself with a certain piece, you will usually never end up with a result that is as good,real,believable, whatever as how you've invisioned it.
But you can still appreciate what you've created, know that the next time you will get closer and that you've improved with this piece, because you pushed yourself.
