Step 1: Materials
General: Scissors, tape( I used black, chrome, and white duct tape), cardboard(preferably thin cereal box kind), rubber bands
Stofen: frosted plastic bowl or tupperware type stuff, knife or something to cut it.
Grid spot: Black straws
Step 2: Bounce Card/Gobo
Lay your flash on the cardboard and mark the width(long side/top). cut a strip along this line. It should be a couple of inches wide. Most of mine are about 3" wide and 4-5" long. You should now have a rectangle piece of cardboard.
Use the duct tape to cover the surface of the cardboard. To make your card do double duty, cover each side with a different tape(ex:chrome on one side and white on the other).
Simply rubber band it to your flash. The side facing the flash will be what gets "bounced". Chrome will obviously reflect more. Use as a gobo to prevent lens flare.
Step 3: Snoot
Simply lay your flash on the cardboard and measure out...just as with the bounce card. This time, rotate your way around the flash.
Crease the cardboard at the lines you made when measuring the flash. This should make a cardboard tube when folded.
Tape the entire surface. I used white at one end and black at the other. The white will soften your spotlight, while black will harden it.
Fold and tape the seam where the two ends meet. That's all!
just slip it onto the flash and if you need to, rubber band it on.
Step 4: Grid Spot
I could go into details, but there are already several good tutorials out there. For mine, I used stir sticks instead of regular sized straws. I simply suck them in a snoot as seen in the previous step.This creates a very soft spot light, but eats up a lot of stops.
Here is a link to an instructable: https://www.instructables.com/id/Black-Straw-Snoot/
you can also make them by stacking and gluing coro-plast sheets together.
Step 5: Stofen
Depending on the piece you have...the simplest way is to cut an "X" in the lid and then slip it onto your flash. Pressure will hold it on. Because of the size of mine..I cut the shape of the flash out and left it just a little bit smaller then my flash...allowing pressure fit.
