The HOYA CRAFT Sq100 Golden Soft filter is an effect filter that soften objects in images while also adding a subtle warm color tone. This creates a cinematic vintage look that makes the filter perfect for both photo- and videography. The Sq100 Golden Soft is available in two densities – 1/4 and 1/8 – allowing the artist to choose freely the desired strength for each individual situation.
The Sq100 Golden Soft slightly softens objects in an image, taking out just a little bit of their sharpness, and gently enhances light sources. The filter's unique feature is that it also adds a subtle warm color tone to the image. This combination of effects gives the image a cinematic vintage look and generally a warm, friendly atmosphere. Great settings can be romantic or happy scenes, but also landscape with warm colors of flowers or sunshine.
In portrait shots, the Sq100 Golden Soft smoothens the skin texture while also giving the skin tone a warm touch, making the model appear glowing with a heightened natural effect.
The Sq100 Golden Soft is available as 1/4 and 1/8, with the 1/4 having the overall stronger softening effect. Tendentially, in situations with strong light sources close to the camera or strong backlighting, the 1/8 is preferrable in order to avoid an overly strong effect. In low light situations, nightscape with light sources far away or settings with weak backlighting, the 1/8 might turn out too subtle, making the 1/4 the preferred choice for a clearer visible effect.
However, in the end it comes down to the artist's preferences and intentions as both densities can work fantastically in all kinds of settings!
Note: The graphs are impressions and only tendencies that should help visualizing the differences. The final effect depends, among others, on the selected density of the filter, camera settings and location.
Low Contrast: High value indicates that contrast is lowered a lot.
Light bloom: High value indicates that there is a strong glow around light sources.
Color balance: High value indicates that there is a strong change in color balance.
Diffusion: High value indicates that there is a strong light diffusing effect.
Definition: High value indicates a strong sharpness of objects.
Soft and diffusion filters are a tool especially used by filmmakers who want to have greater image control. This kind of "on-camera" diffusion is usually used to remove the "digital" look of modern-day cameras. In photo- and videography, it is a great way to reduce that "over sharpness" and "TV look" that is the trend of recent cameras and lenses that come in 8k and above. Instead, through using diffusion filters the photographer can give the image a more artistic look similar to that of cinema cameras even when shooting with DSLR/mirrorless.
