Full-resolution RAW Digital Image Professional Course Photoshop Lightroom Photographer Professional Skills (Color Printing) pdf File Download

Raw is just a storage format and can be opened with the latest version of photoshop. You can explore for yourself. Raw information is rich in storage, which provides many choices for post-processing of photos. I suggest you search these questions again. In the course of digital imaging, I suggest you take a look at Wei Wu's photography lecture, and Baidu. I don't think you need to look at the rest.
