Manipulating Digital Negatives

Although you may be working with images scanned from film or print, it’s almost equally likely that much of your Photoshop fodder will come from pictures captured with a digital camera. If that’s the case, you should know that your digital camera may be capable of producing three different types of image files, all of which are well-suited for enhancing within Photoshop CS. You can learn more about them in my book Mastering Digital Photography. In this section, I’ll provide a summary of some of the information detailed there.

All newer digital cameras produce, by default, JPEG files, which are the most efficient in terms of use of space. JPEG files can be stored at various quality levels, which depend on the amount of compression used. You can opt for tiny files that sacrifice detail or larger files that preserve most of the information in your original image.
