Hi Edmund, the retarder just doesn't last long enough!
Woody the wet palette is a Tupperware tub, with a good sealed lid, 10/12 layers of absorbent paper/kitchen towel and then distilled water, not tap water as the minerals/chemicals can taint the paint.
Fill it, let it stand for a few minutes and pour off the excess.
Then the important bit, a piece of grease proof paper, white, light or opaque not the brown stuff though, and if possible a good quality paper, the one I have, started to degrade and get bits in the paint after 3 days of being wet!
Make sure the tub is big enough, after mixing the flesh and 3 high lights and 3 shadows there wasn't much space left!
Pop the lid back on when you are not painting to keep everything wet, and you will need to re mix the paint on the palette with every use, as it separates also keep the differences between each shade darker and highlights less than you might think, as they will get lighter with time as they get thinner with the water keeping them wet
I remember Alex's blog and have seen the wet palette on the Oliver Kovacs DVD too.
And just have a play, that is exactly what this blog was for, to have a play and see what I could try and do, it hasn't turned out too bad, but I know where I can do better next time.
I'll photo the palette too, as mine is now in the bin!
I'd like to know what kind of wax paper they make over there cause the kind I got starts to tear after a hour or so. So I have moved away from the whole wet pallett.
Nice work Steve, they came out really nice. As you say, the camera probably highlights faults that you won't see with the naked eye, but still, i think you have done really well!
