Introduction: Speedlite "Grid" (as Seen on Strobist Blog)
A "grid" is a great accessory to constrain the output of your speedlite into a nice tight pattern. This tutorial was initially released via the Strobist Blog last fall, and is a great way to use up those pesky political signs you find laying around all over the place after election day.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1
Measure the head of your speedlite and cut a strip of political sign to match the width of the speedlite. Mark plastic corrugated in 1" segments.
Step 2: Step 2
With rotary cutter and ruler, cut 1 inch segments. Hold the ruler down very firmly, to avoid jagged or wavy cuts.
Step 3: Step 3
Trim ends of corrugated plastic to match the contour of Speedlite top. I like to use embroidery scissors for this, but your spouse/so may not be so understanding!
Step 4: Step 4
Cut black foam paper 2 inches by 8.5 inches. You can use any color of that foam craft "paper" but I chose black to match the speedlite.
Step 5: Step 5
Wrap foam paper around grids and fasten with Gaffer's tape. You can get a partial roll of Gaffer's tape from your local school theatre some times, else your local camera shop will have it.
Step 6: Step 6
Slide grid onto speedlite. The extra inch of foam paper will grip the end of your speedlite nicely.
Step 7: Enjoy!
The light is now concentrated in a narrow pattern. The edges of the light pattern seem to fall off more nicely than with my Speed Snoot. Enjoy!
