LrC on the move

An interesting question, and one that I’ve looked at more than once, and written about in another place …

Travelling with my camera and without my MacBook Pro [Updated]

… so you can see that I’ve considered what would be the best way for me to travel with LrC. What do I now consider the best way to take LrC with me when I’m on my travels. There are a number of alternative strategies, so there is no “best” way, just the way that matches best the way you want to work. Lightroom Queen and The Missing FAQ is a good place to validate any of the suggestions below, but as far as I can tell this list, partly assisted by a query to Perplexity is comprehensive.

Method 1. Use the Lightroom app on your laptop, part of your Adobe Photography Plan subscription, and synchronise to the cloud and then again to your main machine when you return home. This is by far the easiest solution and works as long as you don’t use up all of the 20GB cloud storage Adobe give you as part of the Plan. BUT … you do need to remember to delete the images when you’ve transferred them to your main machine – you can do this from the Lightroom app on your travel laptop, or from https://adobe.lightroom.com

This web interface to Lightroom is quite possibly the least used one, but it it is very useful for the single purpose of clearing your cloud storage. Just remember however – you delete the images after the synchronisation from the cloud to your main LrC catalog has completed, and you’ve moved your images within LrC to the folders you want them to be in, from the Synchronisation Folder that you’ve created to receive the images from the cloud. More about this in the article cited above.

Method 2. You deploy a SSD like this one [click on image for further information] …

… to store a specific Trip Catalog with images taken so that you remain within the LrC application all the time. No additional interfaces to learn, just a relatively simple setup and refinement of workflow on your return. For this to be your solution of choice, you need to ask yourself – “Do I need access to my main catalog when I’m away from home, and most importantly – do I need to edit any images in my main catalog when I’m away from home.” If as I suspect (and certainly in my case) you don’t need to access your main catalog then this is the solution for you – and it reduces the weight you need to carry as well.

For this to work well, before you leave home, you need to setup the SSD with a file structure exactly the same as on your main machine and you need to create a NEW catalog on the SSD specifically for the Trip.

When you return from the trip, you open your main catalog and select Import from Another Catalog …

… if you’ve setup the SSD correctly the images will then transfer into their permanent home.

[NB It would be a good idea to test the setup before you leave home, so try importing some test shots into the SSD catalog, and doing a test Import]

A step by step guide to doing this (from Perplexity) is included as Appendix 1 below.

Method 3. This involves taking your existing SSD which holds all your images with you on your travels. [Do you really want to do this??? If you want to take images to show’n’tell it might be safer and kinder to your back to upload them to Google Photos and let them travel in the cloud!!] Perplexity shows how this can be done with a number of alternatives.

Alternative 1. Catalog and photos on same external SSD

The cleanest setup is to put both the catalog and the photos on a fast external SSD and use that single drive with both machine, so you’re always using the same catalog and never have to merge or sync later. [However, this will slow down response to the catalog when working on main machine. This is the way I used to work, but I changed to using Method 2.]

Goal: one external SSD that contains:

  • The main Lightroom Classic catalog (.lrcat and its previews)
  • All original photos (existing and new)

That external drive is then:

  • Plugged into Laptop 1 at home
  • Plugged into Laptop 2 when travelling
  • Opened with the same catalog file on both machines

This avoids all “import from another catalog”, XMP sidecars, manual sync, etc. Everything just follows the drive. A Step by Step guide to setting this up (from Perplexity) is included as Appendix 2 at the bottom of this post.

NB Backups and safety

With a portable library drive, backups are critical:

Never travel with the SSD as the only copy; ideally keep another copy at home.

Enable catalog backups in LrC and set the backup location to a different drive (e.g. each laptop’s internal disk or a second backup disk), not the travel SSD itself.

Back up the Photos folder on the SSD using Time Machine, cloning software, or another external drive.

Alternative 2: catalog on laptop, photos on external

If you’re worried about the catalog on an external drive disconnecting mid‑write (a small but real risk), another common pattern is:

  • Photos on the external SSD (shared between laptops)
  • Catalog on each laptop’s internal disk

However, this requires:

  • Either import/export catalog when moving work between laptops, or
  • Deciding that only one laptop is the “master” and the other is just for temporary travel catalogs that are merged later via “Import from Another Catalog”.

That’s more admin but can be a bit safer from a catalog‑corruption perspective. It sort of gets close to the suggested preferred Method 2 (above).

Appendix 1.

Overall idea
  • Home machine
    • Contains the main Lightroom Classic catalog and the long‑term photo storage.
  • Travel laptop
    • Uses a temporary catalog for the trip only.
    • Stores RAWs either on its internal SSD or on a dedicated “travel photos” external drive (or SSD) during the trip.
  • After the trip
    • Use File → Import from Another Catalog on the home laptop to pull in all new images and edits from the trip catalog.

This way:

  • The main catalog never leaves the home machine.
  • All culling, rating, edits applied on the trip are preserved when merged.
Before the trip (one‑time prep)

On the home machine (with the master catalog):

  1. Make sure the folder structure and backup strategy are solid (master catalog and photos clearly organised and backed up).
  2. Decide where trip photos will end up long‑term (e.g. into a dated structure on a photo drive). He’ll need that when he imports the trip catalog later.

On the travel laptop:

  1. Install Lightroom Classic (ideally same major version as home laptop).
  2. Decide where to keep travel images:
    • Either on the laptop’s internal SSD, or
    • On a small external SSD dedicated to travel (good for capacity and backup).
  3. In LrC on the travel laptop, create a new catalog for the trip:
    • File → New Catalog.
    • Name it something like Italy_2026 and save it in a folder like Pictures/Lightroom/Italy_2026/ on the travel laptop or on the travel SSD.

That catalog folder will contain:

  • Italy_2026.lrcat
  • Italy_2026 Previews.lrdata
  • Possibly Smart Previews.lrdata (if you build them)
During the trip

On the travel laptop:

  1. Always work in the trip catalog (e.g. Italy_2026.lrcat).
  2. Import cards into LrC with photos going either:
    • To a trip folder on the laptop (e.g. Pictures/Trips/Italy_2026/), or
    • To Trips/Italy_2026/ on the travel SSD.
  3. Do normal work:
    • Cull, rate, flag.
    • Apply develop edits, presets, crops, local adjustments.
    • Add basic keywords, collections, etc.
  4. Have a backup routine while travelling:
    • Keep the images on SD cards until there are at least two other copies (laptop + external drive).
    • Optionally use a second external drive or cloud backup if bandwidth allows.

No syncing with the home catalog happens while travelling; you just work in the trip catalog.

When you return home

Goal: bring the whole trip into the master catalog on the home machine, including all edits and metadata.

1. Move the trip catalog and photos to the home system

Pick one of these:

  • If the photos and catalog are on a travel SSD
    • Plug the SSD into the home laptop.
    • Make sure you can see the trip folder structure and the Italy_2026.lrcat file.
  • If everything is on the travel laptop’s internal SSD
    • Copy the entire trip folder (containing the catalog and its photo folders) to an external drive, then copy that to the home machine, or directly into the home photo drive.

Key point: keep the folder structure intact – don’t separate photos from their trip catalog yet.

2. Import from the trip catalog into the master catalog

On the home machine:

  1. Open the master catalog.
  2. Go to File → Import from Another Catalog….
  3. Navigate to the trip catalog file, e.g. Italy_2026.lrcat, and choose it.
  4. In the import dialog:
    • Make sure All folders are selected (unless you want to exclude some).
    • Under File Handling, choose:
      • Copy new photos to a new location and import – then choose the permanent photo location in the main library (e.g. the usual dated folder structure on the main photo drive), or
      • Add new photos to catalog without moving – if you want to keep them exactly where they are on a photo drive that’s already part of the long‑term storage.
  5. Click Import and let Lightroom:
    • Copy/move the RAW files to the chosen main‑library location (if you selected copy/move), and
    • Bring in all metadata, flags, ratings, edits, virtual copies, collections, etc. from the trip catalog.

Now those images are fully part of the master catalog, as if they’d always been imported there.

3. Clean up after merging

Once you have confirmed that:

  • All trip images are visible in the master catalog, and
  • The files are in the expected folders and backed up,

you can:

  • Optionally archive or delete the trip catalog folder (Italy_2026.lrcat and its previews) from the laptop/SSD, keeping it only if you want a belt‑and‑braces backup.
  • Free up space on the travel laptop by removing the local copy of the RAWs (as long as the master library and its backups look good).

Appendix 2.

Step‑by‑step setup for Catalog and photos on same external SSD

Assuming your current situation is:

  • Machine A (heavier laptop), or desktop: LrC catalog on internal disk, photos on external drive X
  • Laptop B (lighter): LrC installed, but no catalog yet
1. Choose and prepare the travel drive
  • Get a fast external SSD (e.g. 1–2 TB, USB‑C/Thunderbolt).
  • Format it in a compatible file system both machines can read/write (APFS if both Macs; exFAT if any Windows involved).

On that drive create two top‑level folders, e.g.:

textLightroom Library/
  Lightroom Catalog/
  Photos/
2. Move the photos onto the new SSD (if needed)

If your existing images are already on a suitable external SSD and you’re happy to keep using that as the travel drive, you can skip this move and just standardise the folder layout.

Otherwise:

  • From Machine A, copy the existing photo folders from the current external drive to Photos/on the new SSD using Finder/Explorer.
  • When done, in the old catalog on Machine A, use Library > Find Missing Folder / Update Folder Location to point Lightroom to the new drive location so the existing catalog now sees the photos on the new SSD.

At this point:

  • Old catalog (still on Machine A’s internal disk)
  • Photos now on the new travel SSD (Photos/)
3. Move the catalog to the SSD

From Laptop A:

  1. Quit Lightroom Classic.
  2. Find the current catalog folder (the .lrcat file plus the Previews.lrdata and Smart Previews.lrdata).
  3. Move that entire catalog folder to Lightroom Library/Lightroom Catalog/ on the SSD.
  4. Double‑click the .lrcat file on the SSD to open it. Lightroom will now run that catalog from the external drive.
  5. In Preferences → General, set “When starting up, use this catalog” to this catalog, if desired, so it becomes the default on each machine.

Now:

  • Catalog and previews live on the SSD
  • Photos live on the SSD
  • Machine A is using the SSD catalog
4. Connect and use with Laptop B (travel laptop)

On Laptop B:

  1. Install the same Lightroom Classic version (or as close as possible).
  2. Plug in the SSD.
  3. Double‑click the same .lrcat file on the SSD (Lightroom Library/Lightroom Catalog/...).

The catalog will open and should show all the same folders and photos because the drive path and structure are identical.

From now on, you always:

  • Connect the SSD
  • Start Lightroom by opening that .lrcat
  • Imports new photos directly to Photos/ on the SSD (set the Destination on import to the SSD), whether at home or travelling

New year with Lightroom Classic – what do I do

The first thing to state (and a very obvious one at that) is Backup your Catalog, and then continue to Backup your Catalog as you try some of these ideas out. That will mean exiting Lightroom Classic and NOT skipping Backup. It’s better to be safe than sorry!!!

So what might you wish to do when Importing images into your catalog?

Two things really, first creating a “preset” for the Metadata that you’d like to import with every image which will then be baked into the EXIF data of the image. The second is the Preset itself which records the action that you wish to take on each Import eg where the images will be stored, in what form, renaming them, making a second-copy, profile changes, etc etc.

Let’s look at each in turn.

You want to add to the Metadata added to the image at the time of import, to add keywords, or to add a Copyright notice. This can be done from the Metadata pull-down menu in the right-hand Import panel …

Screenshot

… and here you have a whole range of options that you can choose from with perhaps the most relevant being the Copyright info. and any info about you you want added …

Screenshot

… so my Copyright info, and the only ones I use in the Metadata, and which I update each year before January 1st looks like this …

Screenshot

… and that’s about it. I enter MLT Copyright 20xx in the Metadata field in the right-hand pane and move to the next step – creating an Import Preset. But before we setup the Import Preset, you need to consider where you want to put the images you’re importing. It is up to you to decide how you store your images, but for a number of years now I’ve stored all my images in folders titled by the year – 2025, 2026 etc. I create them on the fastest drive I have which is the internal one – where I also store my main catalog and the key software files also.

So … it is necessary to move older year folders to a slower external disk, preferably an SSD – YOU MUST DO THIS WITHIN LIGHTROOM though, not in your file system – if you do that you will lose the link between the images and the catalog and the alterations you’ve made to your RAW images.

Once this has been done you can click on the Import tab in the Library module; apart from deciding whether you want to …

NB I almost always choose Copy

… you will see at the bottom of the screen the word None …

You click on “None” to see the range of Presets you can deploy

… unfortunately, this will always be the case; it’s up to you to now create, and then choose the Import Preset you want to use. This has its advantages because you can change the one you want to use by year, by camera, by anything.

So, you set up the parameters from the right-hand pane the way you want the preset to work, eg naming, second copy, location to store images and any other actions to do as you import, and then click on None and …

Screenshot

… Save Current Settings as a New Preset, and you’ll be asked to give it a name, and that’s it. Every time you want to apply these parameters to an Import, that’s what will happen. The files may be renamed (if that’s your wish), they will be copied to a specific folder on your hard disk, etc etc.

Other tasks you may wish to do at year end.

  • Search for missing files (these will be photos in the catalog, but not in folders -they’ve probably moved!)
  • Searching for duplicates – The Lightroom Queen has an excellent post on this topic which I can’t improve upon and recommends a plugin (which I have used) which in the case of simple duplicates works well.
  • For more complicated duplicate problems – perhaps involving whole folders of potential duplicates, its probably far better to use an operating system program such as dupeGuru (MacOS and Windows) or Photosweeper (MacOS) – there are others for Windows that I haven’t tried. I’ve tried both but prefer dupeGuru as it allows you to do a quick sweep by EXIF data, and Content of Pictures specifically.
  • One suggestion I have is to separate folders into catalogs and Export as Catalog before doing any scans for duplicates. When you have a folder that you think is clear of duplicates chose Import as Catalog from the Library > File menu, and when this has been achieved, delete the original folder.
  • This links to another feature that I really hadn’t appreciated until I read this article. Rather than doing move of files/folders INSIDE Lightroom (which is the accepted wisdom to maintain the integrity of the catalog) – which can take a really long time and which is also potentially dangerous in terms of file corruption, use Find missing folder. You chose the old folder in the Library and then point (by right-clicking) to the new folder you’ve just imported.

Backup

All of the above was a preface to doing the real annual task which is creating an offsite backup which up until this year was copying all the images and the catalogs onto a hard disk that I stored in my son’s house nearby. This was the safe/secure disaster recovery option which meant that all my historic images would be safe.

In doing this work, this year, I realised that I’d probably not been as clever as I could have been, and in copying images and catalog(s) separately, I’d been missing a trick. It became obvious to me (light-bulb moment) that I should Export as Catalog (Catalog + Images) to the Hard Disk. This then led to the realisation (second light-bulb moment) that I was keeping a large number of old catalogs, for previous versions of Lightroom that I would never go back to, because if I stopped my Photographic Plan subscription I would still have access to the Library module. Why would I want to go back to an earlier version!

I was on a roll now and looked at other people’s backup strategy. Yes, I was doing the right thing in having a 3-2-1 approach – three backups, two locations, one offsite, but was I really doing the most efficient and most effective form of backing-up. Perhaps (third light-bulb moment) it might be better to clone my Lightroom folder(s) overnight – so that I could quickly recover in the case of primary internal hard disk loss – instead of relying on rebuilding from Time Machine and iCloud Drive; and perhaps it might be better to look at Cloud storage for the offsite storage.

So last year I made a decision to move in this direction and use Carbon Copy Cloner (MacOS only) for cloning to a local hard disk which runs several different clone operations at different times – the most important one being a whole system copy to an external disk.
