A set of three 150x100mm Lee neutral density graduated filters. The most popular reason for choosing to buy Lee filters! The set comprises 1, 2, and 3 stop grads, to allow balancing of a bright area of a scene against a darker one - typically sky versus foreground, but there are many other applications. Available in four graduation types. On full frame format, soft or medium graduations are more generally useful, but photographers specialising in landscapes where there is often a sharp dividing line between sky and foreground (e.g. seascapes) will usually prefer a hard graduation. For smaller sensor formats, Lee recommend using a hard grad set for most scenarios. Supplied in a 'tool-roll' style soft wrap.
