I have CS5 and am wondering if I need Lightroom. What does it do that Photoshop doesn't? Anyone with experience, I'd love some info. Thanks!
I have both CS5 and Lightroom3, and use Lightroom almost exclusively. As far as editing goes, there isn't much that you can do in Lightroom that you can't do in Photoshop, often 2 or 3 different ways. It is just set up with photographers in mind, and the workflow is more logical with how digital images are processed. Lightroom is divided into several modules, each covering a different aspect of digital image processing and management. The Library module is used for getting images available to edit, but actually creates a card catalog of sorts so the program knows where to find the images. You can add keywords, group images from different folders into collections, and can sort through your files and show you all images shot with a certain attribute, a specific lens for example. The Library module is also used for exporting images as TIFF, jpeg, PSD files, etc., and you can add copyright watermarks, and set the image size and quality. Overall, it is a very powerful tool for cataloging and finding images, as well as outputting edited images.
The Develop module is for processing images. The main controls are almost identical to the ACR controls, with some additional controls added. One of the main advantages to Lightroom is that you can edit an image, and Lightroom only adds the processing instructions to the image file; they don't get applied until you export the image out of Lightroom. Since you are only generating editing instructions, you can make as many virtual copies (basically separate editing instructions) as you can keep track of, and they don't take up additional hard drive space.
There are also modules for printing, slideshow and web functions.
This is just a quick overview, and would require a more detailed explanation than what is reasonable for this forum to explain all that Lightroom can do. If you are very proficient at Photoshop, you may not
need Lightroom, but many pros have switched to Lightroom for the majority of their editing because it is set up so intelligently. You may find that Lightroom doesn't fit your workflow, but I know it makes mine much easier.
