coffee

Post by mgausp »

I would like to share with you a detail of a coffee bean. The main challenge here was composition and lighting, since I wanted to highlight the "groove" in the bean. Lighting was done by a Godox V1 with a small teflon sheet as diffuser and a DIY fiber optic setup powered by a Godox AD200, the diffuser was positioned towards the top-right and the two fiber optic ends from above and from the front right. I hope my explanation makes sense and you enjoy the image.

First off, I like coffee, and like this. It shows the unexpected cellular / foamy / bready texture of the bean. If you think the highlights are still bothersome you can try a larger more distant diffuser illuminated by a point source.

I ended up using the plastic diffuser sheets from a scrap LCD monitor - they work great and you get several of them with various "tooth" to them you can arrange in various ways. They are sort of miraculous, having tried a lot of other materials.
