Color film can give quite unbalanced color images as well. It is probably best to judge a color image on the basis of its detail its range of colors and its general beauty. These are subjective judgments indeed. Filter thickness is an important issue when taking three color images. The filters must be exactly the same thickness or there will be an image focus shift at the imager.
Filters vary in thickness considerably.
I have always made a practice of keeping a record of filter thickness for my photographic work. This set of color filters are each exactly the same thickness which is essential for color imaging. The color filter thicknesses in the SBIG color wheel are the same and those in the Meade color wheel are not according to the information I have seen. I hope that this information will be of some value to those considering color imaging.
