Having become accustomed to using a vintage "super" flash for events such as weddings when I was shooting film, I was concerned that the powerful unit would over power my closer digital group images with a too harsh light. Early experiments with my digital equipment confirmed the washout of face tones. Given how inexpensive this diffuser was, I gave it a shot as a potential remedy.
It worked better than I had hoped. Skin tones look far more natural, greatly reducing washout. The large size of the diffuser adapted well to the over-sized head on my super flash. Background shadows were not completely eliminated, but were greatly improved.
Excellent buy for my purposes. I bought a backup.
I use it on the flash that I have. It is easy to apply and softens the flash just like it is suppose to . I use it all the time and like it just fine.
