In photography, soft focus (or soft blur) is a lens flaw, in which the lens forms images that are blurred due to spherical aberration. A soft focus lens deliberately introduces spherical aberration in order to give the appearance of blurring the image while retaining sharp edges; it is not the same as an out-of-focus image, and the effect cannot be achieved simply by defocusing a sharp lens. Soft focus is also the name of the style of photograph produced by such a lens.
I build this website because there is no simple way for people to play with soft focus effet. I want to allow everybody to use it without any photo editing skills, online, and for free. It's a fun effect a lot a people ignore which makes your photos look more dreamy. It also works well removing jpeg noise.
