It came with a diffuser that snaps into the barn door frame. That diffuses enough to hide the multi shadow that you have from the doors. So the net effect is a reasonably good cut from the doors, much better than I would have expected from a multi source array.
So far, love this light both for on camera fill and hair light.
I am looking forward to receiving the barn doors but unfortunately they have not arrived in the UK yet.
Using it for tabletop photography of miniatures. No more clumsy flags on binder clips and tape to prevent light spill. Excellent value and really simplifies setting up.
