A fair amount of my work is based on photographs which I have collected over time. As the weather is not always kind, and as time is often short I found working from photos to be the next best thing to working en plein air.
In the normal way the photo merely acts as a guideline to arrive at a free-hand sketch to form the basis for my painting. On this rare occasion I converted the photograph into an outline drawing using software. That drawing was then transferred to paper but it could have been a canvas or any other working surface to be painted on.
Here is the example on how I achieved this.
The photograph on the left was tweaked on my computer taking out the colour and most of the grayscale to leave me with just a few lines. You will also notice that I have left out the church spire behind the middle ground building as it would have spoilt the view.
I printed the resulting black and white picture on the right and then used my acrylics to add colour. Of course it would have been possible to transfer the drawing onto any other surface using tracing paper. As you can tell by the painting at the top it was not just a colouring-in exercise.
The PC approach was not even a shortcut to help the creative process as it would have been quicker to use a free-hand sketch than to develop the right computer settings to arrive at a printable drawing. On the other hand I would now be able to print as many identical sketches to paint over and generate several originals from the same photograph.
