Aspect Ratio in ImagesLet’s look at this set of images Here, Image A, C, D look similar Image B appears elongated Image E appears compressed Why do these images appear different, or same? The answer lies in the Ratio = π‘Ύπ’Šπ’…π’•π’‰/π‘―π’†π’Šπ’ˆπ’‰π’• Images with same Ratio are similar, But with different Ratios are different Let’s calculate ratios for these Images Ratio of Image A = π‘Šπ‘–π‘‘π‘‘β„Ž/π»π‘’π‘–π‘”β„Žπ‘‘=60/40=πŸ‘/𝟐 Ratio of Image B = π‘Šπ‘–π‘‘π‘‘β„Ž/π»π‘’π‘–π‘”β„Žπ‘‘=40/20=𝟐/𝟏 Ratio of Image C = π‘Šπ‘–π‘‘π‘‘β„Ž/π»π‘’π‘–π‘”β„Žπ‘‘=30/20=πŸ‘/𝟐 Ratio of Image D = π‘Šπ‘–π‘‘π‘‘β„Ž/π»π‘’π‘–π‘”β„Žπ‘‘=90/60=πŸ‘/𝟐 Ratio of Image E = π‘Šπ‘–π‘‘π‘‘β„Ž/π»π‘’π‘–π‘”β„Žπ‘‘=60/60=𝟏/𝟏 Since Ratio of Images A, C, D are same ∴ They look the same And, we can say that these images are in proportion The Ratio = π‘Šπ‘–π‘‘π‘‘β„Ž/π»π‘’π‘–π‘”β„Žπ‘‘ is also called Aspect Ratio Example: Our TV It’s commonly used by graphic designers, T
