Learning to Paint: Painter’s Algorithm

February 22, 2016 at 10:48 am (Art, painting) (, , , , )

I had an important lesson this weekend in learning to paint. I painting a set of peppers with some suggested techniques and colour recipes from a book. The book suggested that I block in my shapes by painting in areas using the midtones of my components. This means that if I have a picture of peppers, I paint the basic shape of the peppers in, then the stems, then the background.

This blew my mind, and I’ll tell you why. In computer graphics and rendering, we use what’s called the “painter’s algorithm”; we draw the shapes in our scenes background first, then foreground. I had always thought that all paintings worked this way; doing your full backgrounds and working forward with layers. While some artists may still do this, depending what their medium (oil, acrylic, watercolour, etc), it isn’t the rule in the way I was expecting it. Furthermore, some colours of paint are transparent or translucent, meaning that some or most of the background will still show through the layer. This makes it not very ideal for some pieces, as you’d have to do multiple layers, or put in a layer of opaque paint first to get the colours you want to show through.

Essentially, my lesson was this: don’t assume that your current techniques are the best, or even the ones you will continue using in the future. Always try to find new ways to do things, even if you like how you paint now. You might like the next technique even more.

Pepper Practice Painting

I’ve started reading books on acrylic painting to build up my knowledge of the medium and some techniques. This is my rendition of one of the suggested practice pieces. It’s about 4 inches across.

I just came back from a long weekend. Here’s some snapshots of some of the projects I played around with. They’re all about 2-3 inches in width.

Taking up painting again

February 8, 2016 at 4:35 pm (Art, painting) (, , , , )

I haven’t been posting here due to posting more often on my LinkedIn page. However, I’ve been taking up painting in the past couple weeks. As part of practicing for a larger piece, I’ve been doing smaller tests to work on my brush and mixing technique. I’ve mostly been using dollar store quality paints and canvas boards, and I’m definitely noticing the limitations lately, but it’s been interesting all the same. Here are a few pictures of my practice.
