Hi Cotty but is a skylight filter not more than just the color correction of to much blue light? It helps in making clouds better visible against a bright blue sky, how do you correct that for example later in photoshop, if the clouds are not on the photo at all? I saw some impressive demonstration photos of filters in a Hoya book and have no experience with digital photography.... thanks Markus
