Black Straw Grids for the Vivitar 285HV

Grids take a standard flash and make it behave like a spotlight. They're made up of a grid of channels for light to pass through (hence the name) and depending on the length and width of those channels they can radically reduce the area lit by a flash, while giving the light itself a nice falloff. You can use them for lighting small subjects, singling out a part of a whole, adding hairlights, tossing up a quick background... all sorts of things! This instructable will teach you how to convert some black drinking straws, cardboard, and adhesives into a light, durable, and effective grid for the Vivitar 285HV flash.

To build one, you will need:

- Black straws
- Non-corrugated cardboard
- Paper cutter (or scissors, or cutting wheel, etc.)
- Straight edge
- Square
- Pen
- Box knife
- Sandpaper (kinda optional)
- Masking tape
- Tube of silicone (durable and heat resistant!)
- Paper glue

Strobist recently influenced me to obtain two Vivitar 285HV flashes for some manual off-camera lighting. The're great! They're sturdy, easy to use, and last for pop after pop when filed with 2700mAh rechargables. They'd make a great addition to anyone's portable yet flexible lighting kit. Slap some grids on them and they're only that much more versatile!

Here you can see a (mostly) completed grid being lit with another identical grid positioned about three feet away. Nice light, huh? Not bad for less than $10 in materials!

So I know there's another DIY grid instructable here, but their technique is completely different, and mine's fit to the Vivitar 285HV, right? I'm not a total hack! I swear! :)

Step 1 Prepare Your Straws

Black straws make a great material for grids. They're easy to work with, durable, won't add much of a color cast to your flash, and you can get them online for cheaps. A box of 500 was less than $10, and I didn't even look that hard.

Straws also create a super smooth falloff at the edge of a perfectly circular spot of light, with just the right amount of specular highlight in the middle, in my opinion. The picture of the spot below was shot on a crappy textured wall... and it still looks smooth!

Unfortunately, my straws came individually wrapped. So strip off all that paper and compost it or something!

Exellent, thanks!

Nice job, well planned and explained. I think the results (and talent of the photographer) say it all.

Just made one and its drying. I used your idea with the straws but i used silver foam board and i'm using foam sheets that you get at crafts stores to attach it to my flash. i cant wait to use it

Thanks much for this instructable, I just made one of these and works fine. :)

i like this instrtble hoping to try it soon congrats on this one i give this a +4 just for you

dangit i have a bunch of straws, but none are right. I have skinny bendy straws, coffee stirring starws, and red coffee stirring straws. Where do i get those darned black straws? I love DIY photo instructables because they always have great quality pictures :D

[richelton]

I must admit I caught myself wondering why I would ever want to use a spot flash.... until I saw your last picture. Now I know. Thanks. :)

What an awesome Instructable! This got my monkey brain rolling for problems I always seem to have with artificial light. Usually I wait for the light to get just right on its own, Ansel Adams style (I was taught by a student of his...), but now I'm going to keep one eye out for great "cheats" like this as I continue my foray into digi. Thanks again, and I dig the rat-personal friend of yours?

I shied away from 'artificial' light in my photography for a long time, having been swayed by the opinion of some ambient light purists early on. It's taken me a while to realize that the look I want IS artificial, mostly thanks to Jill Greenburg. Her work is so sterile, I love it! And yes, that rat is an old friend, no longer with us. Fortunatel, my partner and I have three new ratties to keep our pug & us company. :)

Wow, amazing photos! This is a great job too, it's amazing, very well done, great job, I hope I can try this. +1 rating. (added to favorites)

[Pinkerton]

Thanks a lot, GM! It's comments like yours that keep me going. :)

[GorillazMiko]

No problem. :-) This is a really good Instructable, do you have anymore great ideas? I really like this one.

[Orin]

This came out really well! I still think you should throw up a lighting set-up shot for the lighting for this.

[Pinkerton]

But the lighting set-up was so uninspired! :D
