# Creating a Lightroom Classic Catalog and Importing Photos
{% hint style="info" %}
Recommendation
We recommend creating a separate Lightroom catalog for each photoshoot, as the app performs best when the number of photos in a catalog does not exceed 10,000.
{% endhint %}
### Creating a New Catalog
1. In Lightroom, go to File > New Catalog…
2. Specify a folder for the catalog, enter a name, and click Create
***
### Exporting a Photoshoot to a Separate Catalog
If all your photos are stored in a single catalog, you can export a specific folder to a separate catalog:
1. In the Folders section, select the desired folder
2. Go to File > Export as Catalog…
***
### Smart Previews Support
PhotoPicker also supports Smart Previews.
Benefits of Smart Previews:
* Smaller catalog size
Drawbacks:
* Previews are stored in the DNG format, requiring decoding during each view, which may slow down performance
***
### Importing Photos into the Catalog
1\. Use the File > Import Photos and Video command
2\. In the import window, set the Build Previews parameter to 1:1, select your photos, and click Import
Setting 1:1 provides maximum photo detail, making it ideal for use in PhotoPicker.
If catalog size or import speed is a priority, you can choose Standard instead of 1:1. In this case, you need to specify the size of the standard previews before importing:
* macOS: Go to Lightroom > Catalog Settings…, then under the Previews tab, set Standard Preview Size to 2880 or 2048 pixels
* Windows: Go to Edit > Catalog Settings…, then under the Previews tab, set Standard Preview Size to 2880 or 2048 pixels
### Important: Re-rendering Previews for PhotoPicker
If you edit photos after importing them, Lightroom may delete high-resolution previews for those photos. As a result, you might see the following message in PhotoPicker:
*“Preview for this photo in the Lightroom catalog is not available in sufficient resolution.”*
To prevent this issue, re-render the missing previews before copying the catalog to PhotoPicker:
1. Select all photos in the catalog
2. Go to the Library tab
3. In the menu, choose Library > Previews > Build Standard-Sized Preview or Build 1:1 Preview
Lightroom will render previews only for photos that are missing them.
Once this process is complete, your catalog will be fully ready for use in PhotoPicker.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://photopicker.gitbook.io/v3/lr_catalogs/import_photos_to_lightroom_catalog.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
