first step- when you want to transfer the image onto a bigger canvas put the study in plastic and draw horizontal marks from corner to corner then take a t-square and draw a horizontal line that cuts right thru where the X is. then do the same vertically.this will make four squares with one line going diagonally thru it. then draw a horizontal from corner to corner of those squares. now that will be enough for most easy compositions but if there is a square that has lots more detail in it you can keep drawing more and more squares by drawing corner diagonals and taking the t-square going thru where the diagonals cross.
after this is done you do the same on your larger canvas. now remember that for this to work, you have to have the same ratio of heighth to width. easiest way is to double the size of the study. 9x12 can be done on a 12x16 because the heighth to width ratio is 3:4. or you can go buy one of those proportion wheels at the art supply store to figure it out.
then i paint on rose madder and yellow ochre acrylic washes on the white gessoed panel board i buy at Lowes and cut on my table saw. using a stray tube of charvin paint that looks like alizarin crimson and orange with a touch of green, i draw in the composition and lay in the shapes using varying amounts of Liquin to make the mixtures lighter and darker. if i want it really light i just wipe down to the original acrylic wash that is not affected in the least by the oil paint that was on top of it. cool thing is--this will dry in less than an hour, so i can start laying in my darks. i mix the paint in piles and paint it right on the plastic to make sure the value is right (most important) and the color is close (secondary importance).
here ive got all the shadows laid in. i didnt like the yellow in the sky and on the road in the foreground so i went back with my rose madder acrylic and cooled off those two shapes (not shown here)
i must say, this one's going very easily since ive already done it once before. i'll post the painting tomorrow when i finish it up.
