A Beginners Guide to Oil Painting
About Oil Paints
Oil paints have been used for centuries by the great painters to create all styles of painting. In the early days artists would create their own oil paints by mixing up the pigments with the oil but for artists these days it is much easier to go and pick whichever shade of colour of paint you want from the massive selection of manufactured paints available.
I started painting in oils about 10 years ago and it continues to be my favourite medium. However, I mostly use acrylic paint these days because, as I work as a professional artist, I just don't have the luxury of the time needed to let the paint dry before either putting the work up for sale or finishing a commissioned job.
The Basics of Painting with Oils
If you are just starting out in oil painting then I want to share with you a few basic principles of how to use oil paints.
Firstly, like all painting, I would say that one key factor of a good painting is layers. Don't just decide on a picture, draw it out and then paint it. You need to build up the layers of paint to make a good painting. With this in mind the first rule of oil painting is the well known phrase 'fat over lean'. This basically means that each layer of paint that you put over the previous one should be 'fatter' i.e. it should contain more oil, than the last one. So, if you are starting your painting then the first layer should contain some turpentine (or turpentine substitute/sansodor/thinners type medium) which is the 'lean'. I usually put on a base layer that is quite heavily mixed with sansodor as a very rough sketch of what the painting is going to look like. Don't mix it too freely or the paint will run and separate.
As you continue with your layers, reduce the amount of turpentine and add more oil (there are various oils available - the most common is linseed oil but there are others like poppy oil. Start with linseed and you can always experiment more later). So, for example if I think I am going to use 3 layers in my painting I would have one with turpentine, one with a mixture of turpentine and linseed oil and one with only linseed oil.
Essential Items to Start Oil Painting
There are really two types of paint you can get - student quality and artist quality. I would say when starting out just to get some student quality paints. These are fine for using just for your own work, where you don't intend to sell it and you are just really practising techniques.
Again, you can pay a lot of money for quality brushes and these are good for some aspects of painting, for example when you want really fine detail. But really when you are starting out don't go spending huge amounts on brushes or it will quickly become an expensive hobby. It may also depend on the style of work as to what kind of brushes you need - as an abstract artist I prefer to use big soft brushes that will blend the paint well and I can get these kinds of brushes quite cheaply in craft stores. Yes, I have to be careful when I first use them of hairs coming out, but after the initial use this is much less frequent and I find them create for creating big abstract works.
As mentioned before you will need turpentine (or thinners/sansodor etc) and also some oil (linseed oil is fine). There are many other mediums available and I would recommend you try them out and see what suits you. I often use liquin as a medium when I need to complete a picture quickly as this makes the paint dry at a much faster rate. There are also other quick drying mediums, glazing mediums etc.
The support is what you paint on and in addition to the traditional stretched canvas or canvas board you can paint on pretty much any surface you like as long as it is primed. When you are a beginner though it is easier to just start with shop bought supports and venture into other things later. A good thing to practice techniques on is paper specially designed for oil painting. Be careful with canvas boards as they are liable to warping.
Books in Oil Painting For Beginners
What to Paint
My advice here when starting out would be to get yourself a book with a step by step guide in how to paint a particular picture. It doesn't matter what the subject matter is but this will give you a description of how to paint each layer and how to build up the painting. Once you have done a number of these then you can venture to perhaps painting something that you have photographed yourself. In this way you are creating your own original painting rather than a copy of someone else's.
I love painting in oils because they blend so well together and have such a rich array of colours. The long drying times can be a bit of a pain at times (I have had one painting take 3 weeks to be totally touch dry) but it is the long drying time that really gives it the flexibility. If you don't like something you can just wipe it off and start again!
