Contemporary photography demands careful selection and testing of ND filters to minimize color casts, ensuring consistent tonal quality in black and white photography.

Specialized color analysis software can precisely quantify the extent of color cast introduced by different ND filters, enabling photographers to make informed decisions based on measurable data rather than just subjective visual assessments.

Controlled testing often involves capturing images of a standardized color chart, such as the Macbeth ColorChecker, under consistent lighting conditions, allowing for accurate comparison of color shifts across various ND filter models.

Certain high-density ND filters have been found to exhibit more pronounced color casts in the blue and cyan channels, potentially causing undesirable color shifts in monochrome photography.

Stacking multiple ND filters can amplify the cumulative color cast, leading to even more noticeable deviations from neutral gray tones, a crucial consideration for high-stop ND filter setups.

Historical ND filter designs were often plagued by significant infrared sensitivity, which could introduce unexpected color distortions, particularly in digital camera systems with enhanced IR-blocking capabilities.

Modern filter coatings and manufacturing techniques have greatly improved the color accuracy of ND filters, but variations still exist between different brands and product lines, requiring careful testing and selection.

Comparative testing has revealed that some budget-oriented ND filters can exhibit irregular color cast patterns, with certain areas of the frame showing more pronounced shifts than others.

Evaluating the color accuracy of ND filters is not only important for black and white photography but also crucial for maintaining consistent color rendition in color-critical applications, such as landscape and architectural photography.
