Blenders feature an effect transition that occurs over the entire length of the filter, starting at the top and graduating all the way to the bottom. This allows for a graduated effect across your image without any specific horizon line.
The new Super Stopper works well in harsh midday sunlight - traditionally considered an unfavourable time to shoot. However, with this filter the softness that arises from any movement contrasts pleasingly with areas of bright light, creating an effect rarely seen before now.
The Little Stopper can give increased flexibility with exposure lengths in the lower light at the start and end of the day. This often means that detail and texture can be retained in areas of movement such as the sky and water, while still conveying a sense of time passing.
