What is a RAW File?
- A file that is RAW had not been processed or compressed by the camera
- The camera naturally compresses and processes an image into a JPEG when it is not set
to RAW, which does not allow for the same flexibility in terms of tonal color data.
- The image processor in the camera automatically develops the image when turning it into
a JPEG ; this allows the camera to configure settings such as brightness, sharpening,
contrast, or color.
- The camera’s processing of an image into a JPEG can not be undone and can cause some
of the images potential tonalities to become discarded in the editing process.
- Allowing the file to be RAW until configured via editing can allow for greater flexibility
and potential creative manipulation of the photo.
More Options for Exposure Issues
- The white balance is one factor which can be manipulated by the camera in the process of
configuration to JPEG, so if the file is left raw - the white balance is under the complete
control of the photographer and editor.
- Noise reduction can be more effective when applied to a RAW file as opposed to a
previously configured JPEG from a digital camera.
- Once the camera configures the image into a JPEG, since it can not be undone - there are
some potential highlights, shadows, and details that are lost before any further editing.
- If the file is captured RAW edits can still be made in Adobe Lightroom, but they will not
be automatically and permanently placed on the image by the camera - and thus can
potentially be reversed if necessary.
