Hey All,
I did a couple of simple mods on my Deep Octa to get a honeycomb grid on there. I recently got the rotogrid for my 70cm rotolux and loved it so much I thought I try this out.
First thing I did was add 2 inch white velcro inside the box so that I can get the diffuser hood on without having to thread the rods through those pockets inside the hood that way I can quickly velcro the hood on, so first PIA solved. It's not as taught as it is with the rods inserted but it's good enough.
Secondly I had a local tailor shop sew on 2 inch black velcro on the inner rim of the hood just before the white diffuser cloth. I bought a cheap Chinese 90cm fabric grid and stuck that on the velcro. Since the hood is only attached to the box by velcro and the grid is only 90 cm, it pulls a little bit (as u can see below) but still works fine.
Unit assembled:
Test shot w/ hood, inner and internal diffusers - 160/s f/9
Test shot with grid, external and internal diffusers - 160/s f/8
Power level was the same on both shots, model was about 1.2m from the box, and 1.7 m from the wall.
These were shot with my D700 and 24-70G, SOOC RAW converted to jpg with Capture NX2. Don't have much time to do any real tests, but these quick tests show how it works. Will do some more tests when I get the time. Really busy with the world Expo opening in 10 days (really funky stuff - the UK Pavilion is especially brilliant)
Cheers.
-Pete
