Therefore, you can go back to the original RAW file and redevelop it any number of times without destroying the original image information. The RAW file is developed in a nondestructive way by using a text file that contains your development instructions. The extra bit depth allows you to spread the colors over a greater range creating fewer opportunities for banding to occur.
Having the extra tones can increase editing flexibility, especially when trying to preserve details in shadows and highlights or pulling out more detail in other areas of the image. RAW files have 68 billion colors between black and white JPEG files can have no more than 16 million colors. The difference between the two lies in the tonal range between these black and white points. These values are the same for both for the JPEG and the RAW files. The camera's sensor determines the black and white points of the each camera's image. For instance, if the JPEG camera settings lead to “blown out” highlights (containing no, or very little, data in the highlights), then using 16-bit RAW can enable you to recover that information. Saving an image as a 16-bit RAW file overrides the camera’s compression settings, allowing you to save an image that might otherwise have been distorted by the camera’s compressing the image into an 8-bit JPEG. This allows you to have greater control over the appearance of your final image. removing blemishes, cloning etc.) in your image editor. setting white balance, color temperature, correcting shadows & highlights, etc.) before further manipulation (i.e. RAW images will need to be developed (i.e. It is helpful to think of each RAW file as if it were a piece of undeveloped digital film. RAW files contain the maximum amount of data possible by capturing exactly what the sensor recorded when the shutter was pressed therefore, RAW files hold more useable data than do files in JPEG, TIFF, or other formats. Raw files are 16 bit images, having 4096 tones per color channel, thereby producing over 68 billion colors. | What Are the Advantages of JPEG Files? | RAW Gotchas! | How Do I Develop My RAW Images? | How Do I Save RAW Files For Use in My Image Editor? | Examples | | What is Camera RAW? | What is a Camera JPEG? | What Are the Advantages of RAW Files? | Depending on the camera, you can choose to save your images as a JPEG file with various compression settings, as a TIFF file, or-as many more manufacturers offer this option-as a RAW file.
