I believe that preproduction is the key to success in whole film production. In short words: the better we are prepared, the better effects we will have. Of course, it isnot good to overdo. This may cause lose of creativity and ability to adjust some decisions on set.
I approach each project individually. All films require developing their own language and own visual style.
Based on the project requirements and schedule, I create diverse materials to help the crew work efficiently.
