If there is one thing I love most about using Procreate, it's iteration. Testing out version after version of an idea is a great deal easier and faster on the iPad than on paper, and even in Photoshop on the desktop I would find the extra options and sophistication of the more powerful software a hindrance to my creative flow.
You can see in this process video for the Die Nibelungen how many changes, major and minor both, I made to these designs before landing on the ones I wanted. Siegfried especially changes a lot from the original sketch.
With this pair of posters in particular, it was incredibly useful to be able to work on each design literally on top of the other. This way I could easily keep my compositions consistent between the two posters. This allowed me to use contrasting types of forms (angular and organic) to distinguish the posters within a common overall page layout. That was important for me, since a contrast in the nature of the two halves of the film (as well as between the two leading characters themselves) was the principal concept I wanted to get across.
As wonderful as the app is for this part of the process, it should be noted that in order to get to this stage, I went through pages of pencil-to-paper sketching, note-taking, and serious consideration of themes and what I wanted to communicate. An effective drawing tool in your hand is only as good as the idea in your head.
You can read more about the concept and the film on the Black Dragon Press website.
The posters are available in very limited quantities from Black Dragon Press and Mondo. If you miss out, check my online shop for Artist's Proof copies or sign up to the mailing list to be notified when the APs are available.
