What is the difference between PHOTOSHOP and LIGHTROOM, and when are they used?

Photoshop itself does not support RAW files. You need to edit them in the Camera Raw plug-in first, and then convert them into bitmap files before entering Photoshop for editing. Camera Raw From the main function, both Lightroom and Camera Raw are used to edit Raw files, but there is a fundamental difference between them: Camera Raw is just a Raw editing plug-in, and Lightroom is a set of post-digital photo solutions. You can only edit one photo at a time in Camera Raw, and then enter Photoshop. The function of the plug-in itself is mainly reflected in the format conversion. It is not a complete digital post-work. LightroomLightroom is a complete set of solutions, embodied in its functions including photo sorting, editing, output, printing, publishing and so on. It can be said that from inserting the memory card into the computer to printing or publishing photos, it can be done in Lightroom. There are also some differences between the two in editing functions: 1. Lightroom can keep historical operation records and can interrupt and continue working at any time; Camera Raw is disposable. 2. Lightroom is better than Camera Raw in function and ease of use. In a word, Lightroom is recommended for users who need to manage and edit photos systematically.
