The filter comes in a hard case, which already distinguishes it from low-end filters: it is convenient to use and has a non-slip part with different notches for multiple filter sizes. The construction is excellent and immediately recognizable by the layer applied to the surface, which is a professional tool.
If you're a photography freak like me, you've already tried things like petroleum jelly on the lens, stockings pulled onto a filter, or different films to get an effect similar to diffusion/glow. Here this filter is anything but. It has a sneaky effect and does NOT degrade the image. The edges remain sharp while the colors inside the photo seem to fade slightly, restoring the quality obtained using film: really nice! I bought it for daytime photography, but certainly one of its best uses is with night lights, where you can better appreciate that spread of color and brightness. Although it is an overused term, this filter gives the digital photo pulp an organic feel. I would like to point out that it does not have an obvious and vulgar broad appeal, but is visible without being noticed. Also highly recommended for videos!
