Why do my black and white photos look blue instead of the actual tones in the image?

Skylight, a combination of sunlight and atmospheric scattering, is responsible for the blue tint in photos, especially on overcast days.

The blue tint is more pronounced in black-and-white photos because the blue spectrum is more dominant in skylight.

Camera settings, such as daylight, shade, and cloudy white balance, can affect the color cast in photos.

Using a grey card or a color checker passport as a baseline point in post-processing can help achieve spot-on color balance.

Custom white balance settings in-camera can also help correct color casts.

Print settings and printer firmware updates can resolve blue tint issues in printed black-and-white photos.

Scanning a black-and-white photo does not produce the blue hue, unlike printing.

Photo editing software like Photoshop can correct color casts using the Match Color tool or Hue-Saturation sliders.

Color casts can occur due to incorrect white balance, which can be corrected by adjusting the camera settings or in post-processing.

The sRGB color space is best for viewing images on screens and distributing them electronically.

In GIMP, reducing the blue hue by dragging the slider to the yellow side can correct color casts.

Color filters, like yellow and blue filters, can affect black-and-white photos by darkening skies and increasing separation with clouds.

Curves adjustment layers in Photoshop can boost dull black-and-white photos.

The brain can adapt to color casts over time, making it difficult to notice minor color imbalances.

Color casts can be more noticeable in digital photos due to the camera's sensor and processing algorithms.

Incorrect white balance can cause color casts, especially when shooting in mixed lighting conditions.

In-camera histograms can help detect color casts before taking the photo.

RAW image files contain more color data than JPEGs, making it easier to correct color casts in post-processing.

Softwares like Lightroom and Camera Raw can correct color casts using their built-in tools and sliders.

Understanding the science behind color casts and white balance is essential for photographers to achieve accurate colors in their photos.
