Sky Diffuser

By: Laurent Laveder

 

Region: Europe

Site: Brittany - France

 

Compare these three Milky Way photos above Brittany of France, all taken nearly at the same time and with the same setting but the photographer had used a star diffuser filter on the lens for the middle one and a normal diffuser for the right image. Diffuser filters are used to create soften images in portrait photography but they also diffuse light sources without affecting much the sharpness and contrast of the image, so it is different from the effect of out of focus. For wide-field night sky photography they are occasionally used to make more clear views of constellation by enlarging the image size of brighter stars. This way they also help in better recording star colors. Laurent Laveder/Pixheaven.net
