2. Image conversion - Wikipedia

   en.wikipedia.org/wiki/Image_conversion

   Like any resampling operation, changing image size and bit depth are lossy in all cases of downsampling, such as 30-bit to 24-bit or 24-bit to 8-bit palette-based images.. While increasing bit depth is usually lossless, increasing image size can introduce aliasing or other undesired artifa

3. JPEG File Interchange Format - Wikipedia

   en.wikipedia.org/wiki/JPEG_File_Interchange_Format

   JPEG allows multiple components (such as Y, Cb, and Cr) to have different resolutions, but it does not define how those differing sample arrays (which render bitmaps) should be aligned. This pixel-producing information is rendered with the expectation of indicating rectangles by their centroid , rather than being pixel data directly, or being ...

4. Raw image format - Wikipedia

   en.wikipedia.org/wiki/Raw_image_format

   Simple algorithms such as linear interpolation result in colour artifacts and blurring. If raw format data is available, it can be used in high-dynamic-range imaging conversion, as a simpler alternative to the multi-exposure HDI approach of capturing three separate images, one underexposed, one correct and one overexposed, and "overlaying" one ...
