146: 56:, which lose detail on nearly every compress. While a conversion from a compressed to an uncompressed format is in general without loss, this is not true the other way around. Even a compressed-uncompressed-compressed round trip without any image manipulation may incur some loss of detail. 32:
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. An example of this is
112:, the process of obtaining bitmap data from a RAW-image is always a lossy operation. In addition, some downsampling is always performed, again reducing image information. 187: 100:. RAW is not a standardized format, in fact, RAW-formats even differ between camera models from the same vendor. Data in a RAW-file is structured according to the 36:'s native PSD-format (Prevention of Significant Deterioration), which cannot be opened in less sophisticated programs for image viewing or editing, such as 40:. Most image editing software is capable of importing and exporting in a variety of formats though, and a number of dedicated image converters exist. 180: 121: 263: 268: 173: 258: 52:
