"content": "<h2>Black and White Image Effect</h2>\n<p>The black and white (grayscale) effect transforms a color image into shades of gray. This effect removes color information while preserving the intensity of light, creating a classic and timeless appearance.</p>\n<p>The conversion process involves calculating the luminance of each pixel and setting the red, green, and blue components to this luminance value.</p>\n<h3>Grayscale Conversion Formula</h3>\n<p>The luminance (gray level) of a pixel is calculated using a weighted sum of its red, green, and blue components. The formula for calculating the luminance \\( L \\) is:</p>\n<p>\\[\nL = 0.299 \\cdot R + 0.587 \\cdot G + 0.114 \\cdot B\n\\]</p>\n<p>where:</p>\n<ul>\n<li>\\( R \\) is the red component of the pixel.</li>\n<li>\\( G \\) is the green component of the pixel.</li>\n<li>\\( B \\) is the blue component of the pixel.</li>\n</ul>\n<p>The new color components \\( R', G', B' \\) are then set to the luminance value \\( L \\).</p>\n<h3>Example Calculation</h3>\n<p>Consider a pixel with original color components \\( (R, G, B) = (100, 150, 200) \\).</p>\n<p>The luminance \\( L \\) is calculated as:</p>\n<p>\\[\nL = 0.299 \\cdot 100 + 0.587 \\cdot 150 + 0.114 \\cdot 200 = 29.9 + 88.05 + 22.8 = 140.75 \\approx 141\n\\]</p>\n<p>So, the new color components of the pixel are \\( (R', G', B') = (141, 141, 141) \\).</p>\n<h3>Applying the Black and White Effect to the Image</h3>\n<p>The black and white effect is applied to the entire image by iterating over each pixel, computing the luminance using the grayscale conversion formula, and setting the pixel's red, green, and blue components to this luminance value.</p>\n<p>Converting an image to black and white simplifies its color scheme, highlighting contrasts and textures. The process involves calculating the luminance of each pixel and updating the color components to create a grayscale image.</p>",
