There's this nifty piece of software called Adobe Photoshop Lightroom, and in my time as an educator in the craft of photography I have seen its use frequently abused and mishandled. The issues affect beginners and pros alike, and stem from multiple issues, everything from technical oversight, all the way to a fundamental misunderstanding of what Lightroom is meant for. Read on for an overview of common misconceptions and mistakes with regards to this immensely powerful photo editing system.

I'm not here to teach you how to use Lightroom. I'm here to tell you what to consider before learning how to use it. If you're already using it, I'm telling you what to fix. A lot of these tips and suggestions will apply to any non-destructive catalog image editing program such as Capture One, DarkRoom, DxO Optics, or the defunct Aperture.

It's a UNIX system! I know this!

No, Lex, it's not UNIX (it's actually based on SQL Lite), but notice I said system. And herein begins one of the biggest issues I encounter on a near-daily basis. If you're one of those people who asks a group or forum, "Which do you use or prefer? Lightroom or Photoshop?" you are part of the problem. And if you answer Photoshop, chances are you don't fully grasp what Lightroom is for, either. Lightroom is a fully non-destructive import-to-export database-driven ecosystem that covers ingestion, culling, keywording, folder organization, presets, plugins, batch editing, and export. What happens in Lightroom, (mostly) stays in Lightroom. There's none of this "I use Lightroom sometimes," weirdness I always hear. It is designed to either be used or not be used. There is no sometimes, only Zuul.

You can look at Photoshop as a glorified Lightroom plugin and Lightroom as a glorified combination of Bridge and Adobe Camera Raw (ACR) in a much easier-to-use and polished package. A true understanding of the ecosystem shows that Lightroom and Photoshop are mutually inclusive. Neither truly replaces the other which is exactly why Adobe packages them together for $9.99/mo. You could technically utilize Lightroom entirely without ever editing a photo in it, even if this is a big waste of its power. Part of that power is batch editing. Photoshop really shines at "heavy lifting" editing one image at a time, while Lightroom can edit 800 photos in a single click. Adobe designed them to work together and it's as easy as right clicking on a photo and choosing "edit in Photoshop." When you're done in Photoshop, you just click "Save" and it automatically gets put right back into Lightroom stacked with the original file. Lightroom even has some basic "actions" included, such as the ability to select multiple files and have them open in Photoshop as layers, in a Smart Object, in the HDR dialog, or in the Panorama dialog.

I'm personally able to do about 95% of my editing in Lightroom, and if you primarily just use ACR and "preset toning actions," it'll probably be the same for you. Have no fear, when you need layers, liquify, or some other specialty tool, Photoshop is just one integrated click away.

Respect the catalog.

Lightroom has three major components that all must work together to function, a lot like the human body. The first is the application which acts like the fleshy bag of bones itself. The second is your (hopefully raw) images that are the food needed to function. The third is the catalog file. The catalog is the brain. Virtually everything you do within Lightroom gets stored in the catalog file. If you lose the catalog file, it's no different than losing your brain. You're dead and you have to start over.

There are a number of important things to understand about the catalog file.

The catalog is what allows us to have a full "non-destructive" workflow. Any and all edits you do entirely within the Lightroom interface, including lens corrections and warping, don't ever actually save to your original file. They're all stored and saved in the catalog file with an infinite history. Made 300 brush strokes on a photo? No worries, you can revert to each and every one even years from now. Photoshop only saves 20 steps by default, and unless you save a very large PSD, you're going to lose them all when you save.

Unless you've changed the default settings, every time you close Lightroom it asks you to back up the catalog. This is great, but it is of utmost importance that you understand that this doesn't back up the images. Most of you will say "duh," but this will be a revelation to some of you. Trust me. This is a far more common misconception than you think. You must back up your images on your own. Lightroom has no way of doing that automatically.

The catalog file and images don't have to be in the same place on your computer. In fact, I believe the best way to future-proof storage for visual artists is a modular system where your media is stored on (Thunderbolt, USB 3.0, or eSATA) external drives. For maximum system performance you still want your catalog file to be on your internal drive, especially if it's a solid-state disk (SSD). Lightroom is constantly reading and writing data to and from the catalog, so it should have the fastest path to Lightroom possible. When you import files, you'll want to make sure you choose the correct location, though. Make sure the drive you store your images is selected in the Destination dialog every time. I actually store photos in one of four different drives depending on the shoot, but it's all still with a single catalog file.

Adobe has publicly acknowledged that Lightroom is designed to use a single catalog file. While it is designed to manage multiple catalog situations, these should be only considered advanced or specialty situations. In the early days of Lightroom having a lot of photos in your catalog could impact performance, but several years ago they upgraded how the database is handled so that the number of images effectively has no negative speed impact. External catalogs can be useful as temporary working catalogs that eventually get merged back into a master catalog, but if you're starting out I recommend not doing that until you are intimately comfortable with the ecosystem. There's nothing less fun than accidentally overwriting all the edits from wedding right before delivery. Trust me on that one.

It's smart, but it cannot read your mind.

This is technically another catalog-related issue but it is far and away the most misunderstood and abused issue with Lightroom so we're giving it some special attention. This is also the number one reason why I believe most long-time Photoshop users talk bad about Lightroom. DO NOT EVER move an image without telling Lightroom, ever. Yes, I'm yelling, and no, I cannot stress this enough. From day one, until you no longer use Lightroom, you don't touch an image without informing the application. If you want to create, rename, move, delete, modify, or alter a folder you do it in the Library module in the left pane. As far as your photos are concerned, this is Explorer for you Windows users. This is the Finder for you Mac users. If you make folder and image structure adjustments within the app, it knows. There are very few situations where you ever need to actually go into the image folders via the traditional Explore/Finder route ever again. Do it all in Lightroom.

If for some reason a folder gets moved outside of Lightroom, there will be a little question mark next to the folder in the Library module. You can right click it and try to find it, but if you haphazardly move or delete files and folders outside of Lightroom, you may be in for a world of hurt when you can only find individual files randomly scattered about.

Make plans and organize early and often.

Keywords, collections, flagging, and folder structure are the two most basic and critical components for maintaining both efficiency and sanity. If you don't do it when you start out you'll probably never get around to it. Trust me. I'm more organized than any of my other Lightroom-using friends, and I'm certainly not perfect.

Keywords: You can get pretty picky with keywords, and the more specific you are the better. I personally do pretty broad keywording, but admire anyone who does more. In the import dialog, always fill out basic keywords that can help you find the shoot if you forget where you put it. Locations, topics, people, and even gear involved can all be helpful. But whatever you do, make sure you put in even just a few keywords with every single import with no exceptions. Just a few days ago I had to pull up an image in my library that a tour management company needed for a major advertising campaign for an upcoming band's North American tour. We're talking in the the thousands of dollars for this single image, and they were up against a 30 minute deadline. Of course it wasn't where it should have been in the folder hierarchy. But I was able to quickly find it via a metadata search of the band's name and now I can pay rent and utilities for the next two months thanks to my very basic keywording habits.

Collections: You've got me here. This is something that is really powerful but I've never taken the time to get into. Basically collections are imaginary folders that can hold any images in your catalog without actually moving them from their permanent location. There's a ton of great uses for them, but I think they're exceptionally useful for organizing your portfolio. If you were with a prospective client and they asked you right this second to show them your top 10 best images, how quickly could you provide your portfolio? If you had a smart collection that automatically collected all your 5-star rated images, the answer would be "immediately." Yeah, I really need to do this.

Flagging: The most critical culling/picking action you can do. It should be the very first thing you do after every import. Flag picks (keyboard shortcut P) and rejects (X). Anything you never plan on ever needing again should be rejected. Anything you plan on potentially giving to a client at some point should be picked. If you have photos you may need to reference later or want to save for a rainy day, just leave them unflagged and unrejected. After I have delivered photos to a client, then I can delete all the rejects in a single click. Get in this habit for every shoot and it will keep your library nicely trimmed of useless photos.

Stars: Decide on a system early and stick with it. There's no wrong way as long as it works for you, but Thom Hogan has a great article on dealing with lots of digital images in which he references the great Galen Rowell's "ABC system," which would translate to 'A' being 5 stars, 'B' being 3 stars, and 'C', being 1 star. This gives you 2 and 4 star ratings for images that are on-the-fence and maybe you want someone else's opinion before making a final determination. Five stars would be for real winners. Don't even touch this unless you think the image could be in a coffee table book. We're talking cream of the crop. We're talking a level where even the best photographers in the world might only have a handful of these a year. These are your instant portfolio images and should be ready to go on the cover of a magazine at any moment. Three stars would be for images worthy of selling that you are proud to have your name attached to with a lot of good stuff for broader portfolio use. One star images are for pictures that someone out there would find publishable, but you'd be indifferent to having your name associated with it or not. Maybe these are important images that don't necessarily have a profound style to them. Don't think of 5 to 1 meaning bad to good. Bad photos get deleted. Neutral photos don't get a star rating at all. A good idea of something I'd keep but wouldn't assign stars to would be family formals for a wedding client. They're important to a client, but I'm never going to do anything with them.

Color labels: These are convenient when you want to mark a selection of photos temporarily, such as picks for a blog post or album. Don't use color labels for anything important because they are Lightroom-only metadata. Stars and flags can actually be read by other programs and systems. Colors, usually not.

With regards to flags, stars, and labels, do not mix them. Each does its own thing. Just keep it simple and start out with what's important to you. If you don't have a real use for stars, don't use them. In a few years you may wish you did, though.

Folder structure: This is my first line of organization and how I typically access and find most of my photos. As with most forms of organization, there are a number of ways to do this but in any case start broad and get specific. Here's an example of I handle my live music:

Take advantage of presets and plugins.

Develop presets (like those you get from VSCO, Replichrome, Mastin, and the like) get all the glory in Lightroom, but export presets are one of the great features of Lightroom. First thing's first, you need to understand that Lightroom is designed around the export concept. Since it's non-destructive, you don't save over the original file, ever. Instead, you create on-demand files. If you need to send a file to a client for web-use with a watermark, you create a file specifically for that. If you need to export files for uploading to your album designer, you export a file for that, too. If a magazine wants to use a photo in an article, you send them a file that is specifically exported for that purpose. Exported files are, essentially, disposable after their intended use. If you need it again, you re-export it. Let Lightroom do as much work for you as possible. If you're constantly exporting the same type of file over and over again, make an export preset. It's as simple as entering the settings you want and then click "add" on the left panel. Same goes for regular develop presets. If you are always doing the same thing to every image, make a preset. You can even have presets apply automatically from the import dialog.

Lightroom also has its own plugins to help you out with non-included features. I always suggest a quick Google search if you wonder if something can be done in-app, without going to an external editor. One of the most common comes from Photoshop users who are used to being able to fade the opacity of their adjustment layers and actions. Turns out there's a Lightroom plugin that does just that

There are entire multi-day courses devoted to Lightroom education. I'm very passionate about the program as it's wonderful utility, so I hope to write more Lightroom articles, but this is one that's been on my mind for quite some time. If you have any other Lightroom topics that you'd like to see, let me know in the comments!
