I purchased a filter on EBAY, thinking I was purchasing a "deep yellow" filter (I already have a light yellow filter). The filter is labeled B+W 67E 023 3x The filter, however, looks way more like an orange filter, when compared to the yellow filter I already have. Does anyone know what exactly I purchased? I couldn't reference it on the the B+W site. I don't know what the 67E refers to, but 023, I believe, should indicate a deep yellow filter. The filter is sized to fit 67mm lens diameter, though. ideas?
