For awhile now, I've been trying to come up with an easier take-with-me-everywhere method of plein air sketching. I have full plein air kits for pastels, oil and watercolor, but often I find that even though I keep one of these kits in the trunk of my car, I usually don't feel inclined to bring it all in to a restaurant, coffee shop or on an afternoon trip downtown. I wanted something MUCH more lightweight and accessible - and the iPad has been it.
Here is a sketch from a recent day trip to the ferry building in San Francisco, a busy tourist-heavy area of the city.
My main objective with iPad sketching is to mimic plein air oil paint using the alla prima technique, direct painting, as opposed to more labor intense methods. The idea is to work quickly on site and get it all down in about an hour or so of working. That means everything from gesture, composition, hue, value relationships and light relationships.
About the hardware: I have yet to find a stylus I am completely comfortable with; I am currently using the Wacom Creative Stylus. I am not keen on recommending it, however, because it feels like painting with a giant crayon. I unfortunately purchased the Wacom Creative Stylus 2 and found afterwards that it is not compatible with many painting apps, including Procreate. A few friends have given good reviews of the Jot Adonit Stylus, which is far cheaper and compatible with a lot of apps.
In the Procreate app, I created a set of swatches in the color picker that are the standard colors of my basic oil painting palette, plus a few white convenience colors so that I don't have to constantly mix the same color over and over. Using these swatches helped me in getting a similar look to traditional paintings, although I think I could still fine tune the set.
In addition to that, I am still trying to refine my brushes to find a working method that mimics traditional brushes. Procreate provides a set of brushes that you can then customize, but I have yet to find some that are to my liking.
