I just love gridspots. The amount of light control that a gridspot will give you is incredible. So, a while back I ordered some honeycomb grids from saxonpc. It is with two of those gridspots that I took the image on the left, but first thing first. In fact Saxon PC is specializing in making computer cooling solutions, little did they know that their honeycomb is just perfect for light control. OK, they knew, they made a site for it. Yet it was fun to say "little did they know".
One of the first projects on DIYP was a coroplast made gridspot, which totally rocked, but getting those nice black honeycombs tickled so much and I caved in.
In fact this solution is very similar to HonlPhoto's 1/4" and 1/8" gridspot solutions. If you are willing to settle a bit on the looks and spend a few minutes modding, you can save a few Dollars. Not that a few dollars will take you anywhere today.
