Trying out a DIY grid spot. No PP, just want to see how the light behaves.

Seems to work fine, whats it being used on and how did you make it?

I use a home-made grid spot and put it in front of my 580EX II. I bought some of the coroplast, then glue and stack them up to make a honeycomb shape snoot. It takes a few hours to make it. Basically I'm just trying to use it to direct the light into the subject. Hope to get some photos up when the glue dry.

As promised.
1. Prepare a "Garage sale" sign, rule, cutter, cutting board, duck tape, cardboard paper.

2. Cut up the coroplast and I also painted the interior of the coroplast to black.

3. Stack up the coroplast and then glue them together.

4. A quick look inside.

5. Plug that into the flash and make sure it fit securely. 8 inches long in total.

Seem to remember a snoot I saw in the Canon magazine - made of black straws held together with a stofen diffuser (front cut off) - results looked fine

That's an awesome idea. Thanks for sharing.

If you buy black coroplast you save having to paint the inside.
The black straws take a bit longer to make and give a round light pattern rather than the rounded rectangle. (I have both).
You can alter the size of the emitted light by changing the length of the straws or coroplast.

Yes, unfortunately, I don't get any black coroplast near my area.

I found the local sign writer had stock

Great DIY I just made one but I made it shorter and I love it, just pissed that I didn't think of it sooner

Another variation is to use straws.

This link (http://www.flickr.com/groups/strobist/discuss/72157602692489464/) has nice templates for the grid sizes.

Eventually, I will make one with black straws too. However, I think honeycomb style snoot with coroplate is more structural stable than the ones make with straws especially if you plan to carry it around in a backpack or even a side bag.

This is a grid spot inside a snoot. Couldnt you have made it without the gridspot part and accomplished the same thing? Or just used the grid part? Why both together? Just curious.

Franko515,
The light does come out differently with the snoot vs grid spot. To me eyes, grid spot light come out softer (soft spot light) while snoot act more more like a 'focus' flash light.
That's how I see it. Hope it make sense... By the way, I didn't glue the grid to the snoot itself, so I have the option to get the grid out and use it as a snoot alone.

hmmmmm, I have grids and snoots for my 580EX IIs but never thought to use them together.
If you have time maybe you could post some examples of the snoot with and without the grid and the grid alone, on say a blank wall to show the quality of light from each.

Here is a link (http://www.pbase.com/haverstick/image/97338725.jpg) showing a comparison between a snot / a grid. As masayako stated, grids seem to have a feathered edge and snoots seem to have a hard edge.
-Honeycomb and straw grids are different as well. Straws makes the light comes out circular where as the honeycomb is more rectangular.
-If you don't want to make a honeycomb you can purchase them fairly cheaply here (http://www.saxonpc.com/).

Painting the inside of the snoot white softens the edge a bit.

I know the differences between a grid and a snoot, what I really wanted to see was the effect of a grid snoot combo like the one masayako built. I asked for the testing of a grid and snoot seperate so I could have something to compare it to.

I built a few of these in varying lengths a few days ago. I also used black coroplast, but I was lucky enough to find a local sign shop that a couple of scrap pieces he just gave me. It works great. I also have some of the straw versions, but I like how sturdy these are better than the straw version. This one also took a lot less time to assemble...:D
