For Fat over Lean: When making many layers, fast drying paint mixes first, then slower drying layers later. More solvent makes it dry faster. More oil makes it dry slower. Liquin is special because it acts like oil, but dries the paint very quickly. Below I've created a sort of pseudo-multi layered painting giving an arbitrary random example of how the layers should be applied. Note I don't give proportions, but some artists make different bottles mixed with different solvent and oil concentrations (about 4 or 5 bottles), then use droppers to add to tube paint as they go along: Layered from 1. (final layer you'll apply on a painting, most exposed to air) to 10. (canvas) Air 1. Fattest Layer (Mostly slow drying oil with a little tube paint) 2. Fatter layer (uses other oils or proportions) 3. Fat layer (more oil) 4. Less Fat layer (a little oil, mostly tube paint) 5. Tube paint (no solvent or oils) 6. Lean layer (tube paint mixed with fast drying compound, like Liquin) 7. Leanest layer (Mostly fast drying solvent with tube paint.) 8. Acrylic paint (optional) 9. Gesso 10. Canvas I'll look through my notes for what mixtures of oil vs solvent some professionals told me to pre-mix. If someone quotes this, It'll remind me to look it up in the future.
@@tiagodagostini so true. Also, acrylic paint can be considered your “lean”/ fast drying paint so a painter can accelerate the under painting steps of the old masters then move to oil paint which even out of the tube would be way slower drying/ “fat”. Oil over acrylic is ok, but NOT the other way around. :)
Pro tip, if you paint alla prima in one session, you can ignore fat over lean altogether. It only applies when you paint over multiple sessions in layers. If you are a painter worried about fat over lean, you can relax, just paint.
As someone who like to work in layers (acrylic painter habits), I've never been able to really grasp Alla Prima. To me, it's like just slapping one single little cheap layer of paint, and giving it no depth. This is great for people who paint with solid strokes and impressionistic interpretations, but unless you want to mix all the paint in tiny spots and do quick blending right there, I personally can't truly appreciate Alla Prima. Maybe I'll look up some techniques or something.
While the concept is clear, what to do practically is not. Are you saying you should basically paint "thin to thick" but don't use any solvents or mediums to do it?

This is so much more helpful than any vid Ive watched lmao thank u for this comment
Now I'm even more confused than before.
Here it is: fast drying paint first, then slower drying paint. This only matters with “indirect painting”. This prevents cracking. Simple as that.
Yup , no clue why people try to make it something complex.
Also it only applies to OIL painting, it is irrelevant for acrylics for example.

That was very clear and well-presented. Thank you!
This showed up randomly in my feed and I actually did think you were gonna talk about food. Still interesting though. Thanks, UA-cam algorithm.

When i was taking art classes alla prima always annoyed me because i never wanted to finish it quickly.
Well stated. Just paint.

Forget the details.. just never have somethign that dries SLOWER under something that dries faster.. ONLY THAT.
Drying time is all that matters.
@@tiagodagostiniIs there ever a point when I can paint fast over slow? What if I wait a month until my underpainting is dry to touch?
@@bigmeatswangin5837 Depending hon the pigment and amount of oil you may need to wait a couple of years unfortunately.
Thank you for the analogy of a brick wall! :D :D
Thanks
that was a terrible explanation. All you need to know is what is the first coat. (add linseed oil?) what is the top coat? (no oil added?)
Greater Cpvc ? Academically that's should abriviated sir
