Hi guys, I'm an industrial design student and part time photographer. I'm actually doing my thesis this year and want to design something for photography. I'm frustrated with the topic now, I would be really apperciated if you guys can help m. Can you please tell me what problem you want to solve the most during your shootings? What gears or accessories you like the most or want to have a better one? For ex, the camera diffuser, strap, tripod, bags, etc... Thank you so much!!
