How can I best enhance the clarity and lighting of this photo of my mom?

The human eye can process up to 10 million colors, but most digital cameras can only capture a fraction of those colors, which is why color correction is essential in photo editing.

The concept of "exposure" in photography is based on the Inverse Square Law, which states that the intensity of light decreases in proportion to the square of the distance from the source.

The ISO setting on your camera adjusts the sensitivity of the sensor, but high ISOs can introduce noise, making image correction more challenging.

JPEG compression algorithms discard some image data, which can affect the quality of the image, especially after multiple edits and saves.

The rule of thirds in photography is based on the principles of the Golden Ratio, a mathematical concept that governs aesthetically pleasing compositions.

Red eyes in photographs are caused by the reflection of light off the retina, which can be reduced using specialized flash modes or editing techniques.

High-dynamic-range (HDR) imaging combines multiple exposures to create a single image with more detail in both shadows and highlights.

Digital cameras use a technique called "demosaicing" to interpolate missing color values and create a full-color image from the raw data.

Optical zooms are more effective than digital zooms, as they use the camera's optical components to magnify the image, rather than relying on software interpolation.

The "Orton effect" is a photographic technique that combines a sharp image with a blurred version of the same image to create a dreamy, ethereal atmosphere.

The concept of "color grading" in film and photography involves applying a consistent color palette to evoke a specific mood or atmosphere.

The Fourier transform is a mathematical tool used in image processing to decompose an image into its frequency components, allowing for efficient filtering and manipulation.

The histogram in image editing software is a graphical representation of the tonal distribution in an image, helping photographers adjust exposure and contrast.

Chroma subsampling, a technique used in image compression, reduces the resolution of color data while maintaining luminance (brightness) information.

The human visual system is more sensitive to luminance (brightness) than chrominance (color), which is why some image formats prioritize luminance data.

Image sharpening algorithms, like the Unsharp Mask, work by amplifying high-frequency components in the image, which correspond to edges and details.

The concept of "color constancy" in human vision allows us to perceive colors relatively consistently, despite changes in lighting conditions.

The " Nyquist-Shannon sampling theorem" establishes the minimum sampling rate required to reconstruct a continuous signal, like an image, without aliasing artifacts.

The "zone system" in photography, developed by Ansel Adams, is a method for precisely controlling the tonal range in black-and-white prints.

The "Law of Reciprocity" in photography states that the exposure of an image is proportional to the product of the intensity of the light source and the duration of the exposure.
