Any photographer that takes their work (or hobby) seriously will tell you how important lighting is to your pictures. They will also tell you that the tiny flash that came attached to your DSLR isn’t powerful or versatile enough for many situations. Thus, you’ll end up buying a separate flash, and using it for a lot of your shots. However, after years of use, you might start to think that it isn’t quite as bright as it used to be.
The problem here doesn’t lie with the flash itself, but rather with the piece of clear plastic covering it. Much like the headlights on your car, they can build up a layer of gunk that dulls the light being sent through it. So how do you fix it? The guys over at DIY Photography have discovered that the easiest way is to simply use some toothpaste and a cloth. Work the stuff into the plastic for a bit, and in no time you’ll have a flash that’s just as bright as the day you bought it.
