![]() Data in a RAW-file is structured according to the Bayer filter's pattern in cameras that use a single image sensor. RAW is not a standardized format, in fact, RAW-formats even differ between camera models from the same vendor. More expensive digital cameras usually offer the option to shoot in Raw image format. While increasing bit depth is usually lossless, increasing image size can introduce aliasing or other undesired artifacts. 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. Even a compressed-uncompressed-compressed round trip without any image manipulation may incur some loss of detail. While a conversion from a compressed to an uncompressed format is in general without loss, this is not true the other way around. Most image editing software is capable of importing and exporting in a variety of formats though, and a number of dedicated image converters exist.īesides uncompressed formats and lossless compression formats that can usually be interconverted without any loss of detail, there are compressed formats such as JPEG, which lose detail on nearly every compress. ![]() An example of this is Adobe Photoshop's native PSD-format(Prevention of Significant Deterioration), which cannot be opened in less sophisticated programs for image viewing or editing, such as Microsoft Paint. Many image formats are native to one specific graphics application and are not offered as an export option in other software, due to proprietary considerations. ![]()
