Who seriously dealing with the photograph does not come around to manual settings. Sure, the electronic image processing can very much take off, but I take my time rather than when shooting in front of the PC. In this respect, the use of a white balance filter is essential for me. The ProDisk is a good tool to make a manual white balance. It is simple to handle and allows a white balance in a short time. Some images come more sober therefore, if you shoot a picture with automatic white balance than comparison photo, but that's what it is to go yes. Eben get no supersaturated images with color tables, but ultimately what you also see. So far I am quite happy with the part.
