This camera attachment helps to use a piece of paper or cardboard to diffuse the built in flash. It was tested on the Nikon D3200 and D5600 but will work probably for other models as well. It also is a hot shoe cover and doesn't have to be taken out when you are finished. It offers the advantage that it doesn't cover the microphones on the camera and has a slim profile. You just slide it into your hot shoe mount and add a piece of paper or thicker white cardboard. Pop up your flah and stick the paper in like shown on the pictures and you are ready to go. The result is a more even lighting and no harsh lines.
Have fun with it and share it if you like it :)
