pastel as underpainting for oil?
 

Hi
Today I tried to prepare an underpainting for oil painting.
I did a little background of green -grey acrilic ( I don't know if it's okay),
then I used pastel-pencil ; I fixed it and I began with oil colors.
I made from an ugly photo so I put dead ones.
The canvas is quite large (60 x70 cm) ..next post I'll show the following of it...

This is the complete canvas in pastel ...
And in oil...It's not finished jet. I know there are a lot of thins to
improve.

I've never seen anything like that, but I liked the portrait very much.

Hi Claudemir
I did my son fifteen years ago in the same way.
That's the painting.
ciao

You paint very well Adriano, I liked both paintings very much.
I just would like to know how this sort of underpainting helps you.

Nice weekend.

Hi Claudemir
First of all I only know this way of painting. Unless I follow a Tony Pro's workshop I'll go on painting this way. The advantages are many.
1)you get quickly the cromatic balance by pastel. (if you use turpentine you must wait for a day)
2)You get the shadow and the light value immediately and you have to mix the color already indicated.
3) the shadow can be glazed by a glaze of complementary color that scumbles the final value.
4) some parts of the canvas can remain as you put on pastel initially. You don't have to cover the entire surface.

I forgot the last one!

Very interesting.

I only paint directly on the canvas.

What do you fix the pastel with to prevent it mixing with the paint?

I usually use hair spray becouse it smells good ,but any fixative for charcoal will do.
