About 2 years ago I watched a video by Feng on Design Cinema where he said something to the effect that he doesnt paint with opacity b/c it doesnt exist in real life, colors are what they are. Now I cant find that video again or remember the correct quote.
Anybody know what Im talking about or am I going crazy? Is painting with opacity shit? Right now my results are muddy as fuck with opacity (pen pressure) and you can see all my strokes. I dont know if its optimal.

I think you must've misheard him because he does paint with opacity. He just uses nearly 100%.
>>2871576
so how does he get gradients?

>Right now my results are muddy as fuck with opacity
if you care about colors, use really opaque brushes so that it doesn't mix with whats already on the canvas, then blend them in with opacity brushes
Feng uses 80-90% opacity brushes, theoretically the same thing, but switching between hard fill and opacity brushes. gives you complete and total control over colors.
Reposting an old post of mine I found in the archive:
I've seen plenty of people paint with pressure opacity turned entirely off. Feng Zhu briefly describes the merits of doing this here: https://youtu.be/eaH_WlD_rP4?t=704
I prefer to use 100% opacity for most things, but I use low opacity brushes for glazing-type stuff towards on a mostly finished piece. For line work I set pressure to brush size. For lay-ins I use a hard round or a hard flat (the angle for the flat brush is controlled manually) brush without any dynamics. For texture brushes I do whatever feels right at the time. In any case where I have pen pressure controlling brush dynamics, the pressure curve looks like the the right side of a parabola that sits slightly above the x axis so the brush will always be at least a few pixels wide.

blend tool maybe?
As a /beg/ asking here would it really matter once you're past the block-in stage? I imagine having opacity on would help tenfold in terms of blending. Or am I not understanding something here.
>>2871572
Oh yes, and we all know Feng makes realistic pieces.
When you say paint with nearly 100% opacity, are you just referring to the general opacity setting, or that he turns Opacity Pressure off completely in brush tools (or sets min opacity at 90%)?
>>2871572
He paints with pressure sensitivity turned off, switching the percentage opacity (10%, 20%, 80% etc.) with the number keys. Using pressure sensitivity, however, you can create washes and essentially regulate this effect with pressure as you see fit rather than setting it to a hard limit. The end result is the color of the object regardless of how you got there so if that's his explanation it doesn't make any sense.
>>2871583
Airbrush (round brush at 0% hardness).
Feng a shit though.
>>2871572
He was saying that while demonstrating how to paint values on a cube in perspective. He said that he doesn't advice people to use opacity because it creates muddy values which is not how objects actually appear in life.

Wouldn't switching opacity to different values with the number keys gives you the same results as just having it set to pressure sens? I don't understand.
>>2874096
also forgot timestamp its around 12 mins. where he explains his set up on pen pressure

>Feng a shit tho
That isn't his work tho. It's a student's lineart that he rendered and didn't bother fixing anatomy and design for
