DSLR built-in flash directional diffuser

DSLR built-in flashes are great as a fill-in flash and for general portability. Unforunately they aren't very versatile and give harsh shadows and can overtake a photo. The solution for this is to use a flash diffuser. You can either purchase one that is specifically made for built-in flashes or you can make your own from materials you can find around the house.

step 5Dealing with leaks/rips

If you have some light that's leaking through the cup it may be due to light going through small rips in the aluminum foil. You can either tape the rip or cover it with a s…

step 6Sample photos

These are some photos showing the difference with and without the diffuser. Note: These pictures were taken in a dark room without any other lights.

step 7Other configurations

You can cut a hole on the side of the cup instead of the bottom. This makes it possible to shoot portrait while still having the diffuser pointing upwards. You can also co…
