Acrylics Right and Wrong

IMG_1467.jpg

Our adult art classes were exploring the proper approach to acrylic painting.  The one on the right was a demonstration of a quick, one shot painting.  The canvas was not prepared beforehand and the paint was not dry between layers.  You can probably tell that the colours don’t cover bare canvas very well, and they leave very prominent brush strokes.  The colours in the roses are weak and almost transparent.  You might also be able to see some streaks across the painting that were on the canvas and not sanded out prior to painting.  Only on the right side, where an extra layer of greens was added later, is the look of depth and saturation of colour beginning to grow.

The one on the left was done in class, after several layers of gesso were applied and sanded to prepare the board for paint.  Three or four layers of paint were built up to make a vivid, realistic image.  Finally, a coat of gloss was applied to settle in the colours and make the painting look finished (but also a bit matte for the camera).

This was a great learning lesson which extended over three weeks, beginning with a value sketch and ending with a finished piece.  Check back tomorrow to see the class results.
