The image from Tiffen is from a 1/2 effect. This is for a 1/8th, so it’s more suble and nuanced.
According to Tiffen, their Glimmerglass “is a beauty filter whose function is two-fold: in addition to modifying the appearance of the image itself, it also features a sparkling appearance when viewed from the front, instilling more confidence in the model.

It also produces glowing highlights and a mild reduction in contrast for a more ethereal appearance.” We think it’s odd that they think the sparkling appearance of the filter can instill more confidence in the model.
