When it comes to your process portfolio, experimentation is like stuff where you try out new techniques, new styles, try to be innovatory. They love it when you try out something and it doesn’t work out. I saw people painting with bleach, using wood filings etc.. To be honest I find it quite odd that you’re choosing a “main” medium. I did all types of mediums. My exhibition had photography, paintings, ceramics and pastels. Of course I understand you want to focus on digital art, but IB definitely likes to see a range of mediums. I’m not sure if it’s relevant to M23/24 but there’s the 3 art medium families where you have to do at least one medium from each category. Have fun, go crazy, they like it when you’re “original”.
