 +====== Big Disadvantage of Catalog Concept ======
 +
 +**You can't shift and move around those original photo directories**
 +  * just like a web page link to the image directory, Lightroom catalog is pointing to those original photo directories,​
 +  * once you move, you break the linkage in lightroom catalog database, and you have to re-link them, if you shuttle sub directory and name change, the process can be more detective and by how smart lightroom is.
 +
 +**Backup Original and Editing info always with concern to the catalog file**
 +  * if your catalog don't associate with multiple devices for its photos, then it is easy to leave the catalog on each device, and re-point the device to update a backup copy
 +  * if your catalog links to multiple device, then in order to use that backup, you need to update the device list in catalog again.
 +  * so you can't use backup copys in lightroom before let it update the directory locations
 +
 +**It is a risk to put "All the eggs" in one basket** ​
 +  * Lightroom used to get slow when the catalog grow over certain size, but now you have no limit in catalog size performance
 +  * However, the best practice with catalog may be "Each Catalog per Project",​ just like "Each PSD per Photo"
 +  * In contrast, you may need to find a balance for your workflow, since there is always How Many databases you need to Manage "​Personal,​ Shortlist, Best, Clients, Current Shoot, Tmp Edit"; that makes a point to decide whether you use lightroom or manage yourself with standard file explorer; and whether you need Lightroom to assist you on photo management
 +  * also, in single catalog, if you run out of disk space as catalog grow, you can't add into the catalog anymore, and you can only continue to use lightroom if you change to a bigger disk.
 +  * so instead of many photo directories,​ you manage many photo catalogs
 +
 +**Your are forced to backup everything again and again if you use single catalog**
 +  * not all photos are on the same level of importance, I may only like to backup certain photos not all every time
 +  * all your changes are in one file, you have to roll back all photo changes in catalog if only one change is corrupted.
 +**No advantage clone retouch heal combination**
 +
 +**No Layering and Compositing**
 +
 +**Single User workflow, Catalog can only be changed by single user compared to normal folder structure**

 +===== Managing by Folders by Yourself =====
 +
 +  * Year_Folder
 +    * Date-Project_Name
 +      * shortlist_folder
 +  * Best_of_Best
 +    * catalog file for search
 +    * album_name
 +
 +====== Advantage of Lightroom Catelog system ======
 +
 +**Deal with multiple Cameras and multiple Photographers for single project**
 +
 +  * automatically figure duplicate names from different camera sources. ​ (use Lightroom import)
 +  * automatically avoid duplicates from same SD card again and again
 +
 +**rating system**
 +
 +**batch processing for large photo pool**
 +
 +**multiple collections without duplicate folders**
 +
 +====== Breaking Point with Lightroom ? ======
 +
 +**What is equivalent workflow in lightroom?​**
 +
 +  * in Photoshop, the process flow is
 +    * **Original Photo layer -> Retouch and Fix with original layer -> Color and Exposure Grading layer**
 +  * the above workflow in Photoshop will break if flow like below
 +    * Original Photo layer  -> Color and Exposure Grading layer -> Retouch and Fix with original layer 
 +    * since every color change, the retouch and fix clone won't carry over those color change and still with previous color version; as behind the scene, you are painting pixels, and photoshop layer only record the result pixel, not the brush stroke motions and steps; and also color grading got baked into retouch and fix layer
 +
 +  * quote: "If you did the color treatment or color grading first in your workflow and then the client didn't like it, or wanted changes it could be an issue with all your subsequent cloning, healing, copying image parts done down the line.  All those layers would have to be re-done to match the color change."​
