flash diffusion
As winter doesn't have much insect activity, it's the season I use to work on my equipment. Yesterday I tried out a new arrangement to diffuse the heads on my mt-24ex twin flash when the heads are mounted on long, moveable arms. Here's a time-lapse video showing the construction, plus a short clip of the gear in use:
Note the effect of the diffusion:
A bare, undiffused flash produces harsh shadows and glare
A diffused flash provides softer, more even lighting
