I'm having such a great time playing around with my old(ish) DSLR, Sony Alpha 200 and my new portable flash (super inexpensive yet high quality - search Bower SF02965 on Amazon) that I wanted to share it with all of you.
But... like I've mentioned before, I totally suck at tutorials. I try but I just can't bring myself to meticulously take the pictures during the process and organize everything just right. It just takes the fun out of it and I'm not sure why it's worth doing if I don't enjoy being in that in-the-moment, creative zone and getting my hands dirty.
So... what I can do is give you a good idea of how I made these and then maybe you can go from there. You can do it! If you have any questions, I can try to answer them in the comments below.
Have fun! Experiment! Break the rules! Do it your way!
Step One: Find a translucent, creamy white, plastic take-out container. Not opaque like a milk container but still white.
Step Two: Make some (very) loose measurements - I totally eyeballed it four times - and cut your plastic so that it will fit over your portable flash with overhang on top and bottom. Now score the plastic with a craft knife at top and bottom where you'll be folding it over the flash. This just makes it fold over easier.
Step Three: Use Sharpies to color your diffuser if you want. You could make a solid color like I did or experiment with gradients.
Step Four: Fold over a long piece of duct tape so that it's not sticky except for at the very end. Now you want to wrap it all around the sides of your plastic diffusers to keep the light in (instead of flooding out the sides) when you snap a pic. Then wrap a regular long piece of duct tape around that so that everything is secure on all four sides.
Step Five: Add clear male velcro to your flash and small female velcro dots to the inside of your diffusers. Because your flash is inexpensive, adding a few dots of velcro doesn't hurt so much and you can have more fun and be more inspired by your equipment instead of feeling like things have to be babied due to the fortune you spent. These cameras are pricey enough, amiright? May as well have a good time using them.
That's it. These are really fun to play with in low light so that they illuminate your subject nicely with various hues. I'll try to get some pictures of the inside of the diffusers, velcro, etc. as well as some test shots with each color in the near future and tack them on to this post with a quick edit. ;D
