Scotchlite Problem

[Guest]

There is a huge difference in the two photos. I usually shoot with flash on manual and depending on how close will shoot on 1/4, 1/2 or full power. The worst thing with the Scotchlite is the flaring you will get from the silver part. I have read theories about it, like it is caused by a filter on the front or something getting bounced through the lens. Don't know why it happens but it occasionally does. It does seem to happen more frequently with a zoom lens.
