RAW Images RAW Images A RAW image is image data that has recorded output data of imaging sensor. As image processing is not performed inside the camera when a photo is taken and the photo has been recorded in the special form of "RAW image data + Image processing conditions information at the time of shooting", special software is needed to view or edit the image. * "RAW" means "in a natural condition" or "not processed or refined". RAW Development If described in terms of film, the concept of a RAW image is a shot image not yet developed (latent image). With film, the image appears for the first time when it is developed. In the same way, for RAW images too, you cannot view them as images on your computer unless you perform subsequent image signal processing. Therefore, even though it is digital, this processing is called "development". When RAW Development is to be Done DPP automatically carries out this "development" processing when RAW images are displayed in DPP. As a result, RAW images displayed in DPP are images whose development processing has been completed. With DPP, you can view, edit and print RAW images without being particularly conscious of the development processing. Introduction Advantages of a RAW Image RAW images are recorded in the format "RAW image data + Image processing conditions information at the time of shooting". When you open a RAW image in DPP, the image is automatically developed and you can view the image as an image to which image processing conditions at the time of shooting have been applied. Even if you perform various adjustments to the image you have opened (it undergoes automatic development processing each time), only the image processing conditions (development conditions) change and the "original image data itself" remains unaffected. Therefore, it is the perfect data for users who want to get creative with the images after shooting, as you do not have to worry about image deterioration. In DPP, the "Image processing conditions information" that can be adjusted is called a "Recipe" (p.89).

In DPP, all the adjustments (image processing conditions information) made with the tool palettes can be saved in the image as data called a "recipe" (p.90), or can be saved, downloaded and applied to other images as a separate recipe file (extension ".dr4", p.91). However, a recipe file with saved RAW image adjustments cannot be applied to JPEG or TIFF images. 5Printing Images 6 Processing Large Numbers of RAW Images 7Remote Shooting 8 Specifying Preferences Reference/ Index 40
