Hello, I recently bought a godox sl-60 light and a softbox, and now I would like to experiment with colors. So I'm wondering how to attach some gels: in front or inside of the softbox. I'm thinking that: If it's in front I would need really big sheets to cover all, maybe a bunch of small ones to make a bigger one? If it's inside (separated, lets say, 4 inches from the chip), it seems to block the airflow from the cooler devise inside the light, I could damage it? Let me know please if I was clear. I'll attach a picture of what I mean by inside (this photo is for a flash light, it doesn't get hot, so it doesn't clear my questions) Thanks!
