Part of the conversion to JPEG are sharpening algorithms and as a result, the unprocessed Raw file is less sharp. As a side note, all of my work that uses creative coloring was colored using the white balance settings in the Camera Raw dialog. The richness, detail (sharpness), color range and ability to adjust these settings end up being so much greater with a Raw file, even though what a Raw file looks like before processing is anything but rich and sharp. If the white balance is off I have found that it is much easier to fix using the Camera Raw screen than loading the JPEG and manipulating that – the end result is much better as well. Most of the time the automatic settings are fairly decent, but you have the chance to change the white balance, exposure, contrast, saturation, and even calibration of the red, green, and blue guns or correct for lens abberation – all lossless. When you load a Raw file using Adobe Photoshop CS2 the Camera Raw dialog will automatically pop up. I have found the Camera Raw that comes with Adobe Photoshop CS2 to be very good at processing Raw files (even batch processing them), though everybody has their favorite (RawShooter has a lot of fans). To take advantage of this you will certainly need to use some software on your computer to process the files and produce JPEGs (or TIFFs). Guess which has more processing power: your digital camera or your computer? Shooting in Raw will give you much more control over how your image looks and even be able to correct several sins you may have committed when you took the photograph, such as the exposure. If you do shoot in Raw, your computer rather than the camera will process the data and generate an image file form it. at the best of the specific sensor’s performance) the radiometric characteristics of the scene, that is, physical information about the light intensity and color of the scene. Raw image formats are intended to capture as closely as possible (i.e. The purpose of raw image formats is to save, with minimum loss of information, data obtained from the sensor, and the conditions surrounding the capturing of the image (the metadata). Like a photographic negative, a raw digital image may have a wider dynamic range or color gamut than the eventual final image format, and it preserves most of the information of the captured image. The selection of the final choice of image rendering is part of the process of white balancing and color grading. Likewise, the process of converting a raw image file into a viewable format is sometimes called developing a raw image, by analogy with the film development process used to convert photographic film into viewable prints. ![]() Raw image files are sometimes called digital negatives, as they fulfill the same role as negatives in film photography: that is, the negative is not directly usable as an image, but has all of the information needed to create an image. RAW image files can be edited by Adobe Photoshop and Corel Paintshop Pro. ![]() JPEG files, but is slightly smaller than. RAW files are considered to be the best form of image file, since it does not process the picture, leaving total control of the editing to the user. RAW is an image file format used by many high-end and professional digital cameras.
