Ever since I got an external flash for my Canon Powershot G5, I have been researching and building home made light modifiers. Some are more elaborate than others, some look better than others, but they have all had the desired effect. Here is a rundown of the ones I have tried, with links to instructions (some might go to videos). The DIY softbox above is one I have not made yet, but you can get the plans here. [edit - on 12/14/08 I made it and then did a review]
Milk Jug Diffuser
The milk jug diffuser is one of the simplest ones to make. Lop off the end of a milk jug, slot the edges so it will wrap around your flash head, and presto chango – instant diffuser. Not as pretty or professional looking as a Gary Fong Lightsphere, but it will get the job done. I haven’t made one of these yet. We have our milk delivered, and their jugs are much heavier gauge than the store bought ones. Hmm, that might make for better diffusion though. I’ll have to see if they are so thick as to not be pliable enough to fit on the flash.
MuzzBounce™ Ghetto Flash modifier
The MuzzBounce™ Ghetto Flash modifier is similar to the milk jug diffuser in that it uses a translucent jug (mine was from windshield wiper fluid). The effect is different though. It is designed to redirect (bounce) the light from a flash, while at the same time diffusing it. It works quite well in portrait and macro photography. I built my first one shortly after I got my new Olympus E-510 and FL-36 flash. My wife made a comment immediately, something about spending so much money on a camera only to put a jug on it. I thought it was a funny comment, but it didn’t stop me from using it around the house. Certainly doesn’t project a professional image though. Not really sure what the “professional” (store bought) equivalent would be, but if you spent enough time on this one, you could make it look professional.
DIY Reflector-Diffuser
I have a slightly different version (cannot find the site it was on now) of the DIY Reflector-Diffuser. It is on;y slightly different, and the results are pretty much the same. I like it so much, I keep it in my camera backpack all the time and use it fairly frequently. Construction is very easy, using craft foam from a hobby shop. The DIY Reflector-Diffuser site also includes plans you can print and use as templates when cutting the craft foam. This is a “must make” for the do it yourself light modifier. Other alterations I have seen include cutting a honeycomb pattern (with large hexagons) into the modifier to let more light escape vertically.
A Better Bounce Card
This was one of the first thing I tried. A simple bounce of light from my flash, that allowed enough light loss to spread the remaining light out properly. It worked OK, but I certainly liked the results from my Muzzbounce better. The plans for A Better Bounce Card have been updated to use craft foam. I think the original may have been something else, as simple as copy paper. It certainly served it’s purpose though.
The Finn Bounce
For those of you with a P&S camera that has a pop-up flash (or even a DSLR like my E-510 that has a pop-up), the Finn Bounce is an easy to make light reflector (bounce card) that, given it’s size, has a tremendous impact on the quality of your pics. Don’t take my word for it, find a piece of cardstock, rubber cement and aluminum foil, then follow the 9 easy steps to make it. You will be glad you did.
This covers the ones I have tried. Below is a list of ones I want to try, along with the softbox that led this article. Hope this has been worthwhile to you.
Miscellaneous Others I Have Not Tried
Here are some highlights of projects I plan to try at some point:
Using a flat fluorescent light fixture I picked up at Home Depot, and a piece of black craft foam, and my large DIY light tent with glass riser, I was able to get the photo above. I cut a hole in the black craft foam that was roughly the same size as the base of the glass. I then put my black backdrop into the light tent, set the fluorescent light on my workbench inside the light tent, and then placed the craft foam on top of that so no light escaped except through the hole I had created. From there I inserted my glass sheet to have a riser (which was conveniently about an inch higher than the surface of the fluorescent light), filled the drinking glass with beer, and turned on the light. This photo did not require any additional lighting other than the fluorescent underneath the product. And by using the pane of glass as a riser, a nice reflection appeared as well.
Shooting Highly Reflective Surfaces
I have scored a few product shoots because of my demonstrated ability to take good pictures of glass objects. Truth be told however, there really isn’t a whole lot to it.
First step is to have the proper environment to shoot in. For me that means using my oversized DIY PVC Light Tent. It is big enough that the light is distributed really well within. For added measure, when I was building it and then making the second revision, I made sure that the fabric would cover any of the PVC so it would not show up as a reflection in the objects I was shooting.
Second step is, obviously, lighting it. When shooting in the big tent, I tend to go between two different placements for my lights. I use a pair of 27W, 5500K compact fluorescents in standard 10″ clamp light fixtures I got at Home Depot. Sometimes I will place them slightly ahead of center on either side of the tent. Other times I will put them overhead, either facing directly into the tent or bouncing the light off the rafters overhead (sounds goofy, but it works). I take a couple of shots, see how they look, and then readjust as necessary. Most of the time I can get a good idea of how the lights are working from peeking through the viewfinder and then adjusting.
I generally do one or two shots in auto mode to get some idea of the f-stop and exposure ratio, then start working from there. As you can see from the EXIF for the shot above, it can be fairly fast. But again, that depends on how you light it.
One key I have been working on is how to keep the camera reflection from appearing in the object. I account for this in a couple of ways:
1) The opening in my front curtain is only large enough to let the lens through.
2) I do not use any sort of lens hood.
3) When practical, I elevate above the object and shoot downward at an angle. Straight on shots are the worst for showing the camera lens, and I try to avoid this at all costs.
4) When 4 isn’t practical, I try to get any opaque objects on the surface of the object to be in the forefront.
5) When 3 and 4 don’t work, I just deal with the fact that the reflection is part of the image.
These things must be working, as I continue to get product shot engagements, and several specifically indicate it is because of my work with highly reflective surfaces.
