How can I restore and enhance these two portraits, considering they're my only photos of me?
TheRule of Thirds: Divide your image into thirds both horizontally and vertically, placing important features along these lines to create a more balanced and visually appealing composition.
Color Harmony: The 60-30-10 rule suggests using a dominant color (60%), a secondary color (30%), and an accent color (10%) to create a harmonious color palette in your portrait.
Lighting: The Inverse Square Law states that the intensity of light decreases in proportion to the square of the distance from the source, making it essential to position lights carefully for optimal illumination.
Camera Sensors: The Bayer Filter, a mosaic of color filters on camera sensors, captures colors by interpolating values from neighboring pixels, allowing for detailed color representation.
Image Resolution: The Nyquist-Shannon Sampling Theorem dictates that the minimum sampling rate required to reconstruct a signal is twice the bandwidth of the signal, influencing the resolution of digital images.
Noise Reduction: The Gaussian Distribution is used to model random noise in images, enabling noise reduction algorithms to effectively remove unwanted artifacts.
Cropping: The Golden Ratio (1.618:1) is an aesthetically pleasing aspect ratio, often used when cropping images to create a more balanced composition.
Facial Symmetry: The Pareto Principle (80/20 rule) can be applied to facial symmetry, where 20% of facial features often dictate 80% of the overall facial attractiveness.
Background Removal: The chroma keying technique, using a green or blue screen, relies on the principle of color difference to separate the subject from the background.
Skin Tone Enhancement: The CIELAB color space is used to quantify and adjust skin tone colors, enabling more realistic and natural-looking enhancements.
Eye Sharpness: The Circle of Confusion, a concept in optics, determines the maximum acceptable circle of confusion (CoC) for a sharp image, which is typically around 0.03 mm for a 35mm camera.
Hair and Fur Removal: The Lasso Tool, commonly used in image editing software, is based on the concept of active contours, which track the outline of an object using energy minimization.
Artifact Reduction: The Fourier Transform is used in image processing to reduce artifacts by analyzing and filtering out high-frequency noise.
Image Compression: The Discrete Cosine Transform (DCT) is a mathematical algorithm used in JPEG compression, reducing image data by approximating redundant information.
