What type of file provides data for an image in an unprocessed form?

1. JPEG

2. PNG

3. Camera Raw

4. TIFF

The correct answer is: Camera Raw

A Camera Raw file is a type of image file that contains unprocessed, uncompressed data captured directly from the camera's sensor. This format retains all the details and nuances of the original image, allowing photographers to manipulate elements such as exposure, color balance, and other parameters without any loss of quality. It provides greater flexibility in editing because the raw data contains more information than traditional processed formats like JPEG or PNG. Camera Raw files are specifically designed for post-processing, which is essential for professional photography where achieving the best quality is paramount. Other formats, like JPEG and PNG, apply compression and processing that may result in a loss of detail, which limits editing capabilities. TIFF files are often high-quality and can be uncompressed, but they are still generally considered processed files, typically used for publishing or printing rather than raw capture.
