Emisar D1 / D1S review

Thanks for the answer. This is here DC-Fix Diffusion Film Sale
Where can I see the photo, to understand how to do it?
P.S “Because the Butler Creek Blizzard scope cover gives you the BEST of BOTH worlds. It adds very little girth to the D1 and weighs hardly anything….“

What are the options for attaching the film to the flashlight Emisar D1?
