Product Comparison: White Balance Filters
By Stan Sholik
If the number of products available to pre-capture white balance digital cameras is any indication, professional photographers’ interest in creating a neutral color balance must be very high. There is a good reason for this of course. While professional digital cameras do an excellent job autofocusing and autoexposing, auto white balance is not likely to give accurate, consistent color under many ambient lighting conditions.
White balance isn’t that much of an issue when making RAW captures as it is easy to adjust when processing the files, though it adds work time. When capturing in JPEG, or RAW + JPEG formats, it is important to have as accurate and consistent color as possible to reduce additional processing and saving of the compressed file.
With prices ranging from $8 to over $100, I thought it would be interesting to test a few of these white balance filters under actual ambient lighting conditions to see if they produced an accurate white balance and to examine the advantages or disadvantages to each. One of my photographer friends swears by Mr. Coffee filters for white balancing, and I was curious to see if he was really serious! My store was out of Mr. Coffee brand but had Melitta Junior Basket filters in stock, so I picked up a pack for testing.
Along with the Melitta, I tested five filters designed for professional photographers: the ClearWhite, ExpoDisc Neutral, Lally CAP, Mennon and Phoxle SpectraSnap. Designers of each of these photographic filters took a slightly different approach, and one approach or another might influence your decision as much as the accuracy of the white balance.
