Assignment #3: Jpeg vs. Raw
Jpeg: A file format that is processed right inside the camera that vary from each camera model. Jpeg’s are readable by any image program on the market or available open source, has exactly 8-bits of colour (12-bits per location) is compressed (by looking for redundancy in the data like ZIP file or stripping out what human can’t perceive like a MP3). Jpegs are also small in file size an 8 megapixel camera will produce JPEG between 1 and 3 MB’s in size. Jpeg formats can be saved in any image program from the pre-installed paint program in virtually every home computer to more advanced Adobe photoshop and other photo editing programs.
RAW: is a file format that captures all image data recorded by the sensor when you take a photo. When shooting in a format like JPEG image information is compressed and lost. at least 8 bits per colour – red, green, and blue (12-bits per X,Y location), though most DSLRs record 12-bit colour (36-bits per location). Uncompressed a raw file is much bigger, an 8 megapixel camera will produce a 8 MB Raw file in size. Because no information is compressed with RAW you’re able to produce higher quality images, as well as correct problem images that would be unrecoverable if shot in the JPEG format. Â
