During the last three years I have use sketchbook as journals. On them I have represented using different styles and techniques places, objects, people and experiences I met.
In some occasions I would film the process of the drawing.
Many times when I was sketching, I would set up my camera and would shoot a timelapse of myself within the landscape.
In general it was a really good way to record a journal, meet people and see things in detail. I have some ideas for those sketches but they haven't seen the light yet.
You can see more of these on my YouTube channel.
