Lightroom and Photoshop Round-Trip Editing Guide

The round-trip editing workflow between Adobe Lightroom and Adobe Photoshop allows photographers to harness the organizational and global adjustment tools of Lightroom alongside the advanced pixel-level editing capabilities of Photoshop. This process lets you send a raw file from Lightroom to Photoshop, perform intricate edits, and automatically save the modified file back into your Lightroom catalog right next to the original asset without losing your place.

Configuring External Editing Preferences

Before starting a round-trip edit, you must configure Lightroom's external editing preferences to ensure optimal image quality and color fidelity.

  1. In Lightroom, navigate to Preferences (Mac: Lightroom Classic > Preferences, Windows: Edit > Preferences).
  2. Select the External Editing tab.
  3. Under the Edit in Adobe Photoshop section, select your target parameters:
    • File Format: Choose TIFF or PSD. TIFF is broadly compatible and supports ZIP compression, while PSD is Adobe’s native format.
    • Color Space: Choose ProPhoto RGB to preserve the widest color gamut captured by your camera sensor.
    • Bit Depth: Choose 16 bits/component to prevent banding during heavy color and tonal adjustments in Photoshop.
    • Resolution: Set to 240 or 300 pixels per inch.

Sending the Image from Lightroom to Photoshop

Once your preferences are defined, you can initiate the round trip from either the Library or Develop module.

  1. Select your target image in Lightroom.
  2. Apply your initial global adjustments (exposure, white balance, lens corrections).
  3. Right-click the image and select Edit In > Edit in Adobe Photoshop, or press Cmd + E (macOS) / Ctrl + E (Windows).

Alternative Send Options

Lightroom provides specialized methods to open files in Photoshop depending on your creative needs:

  • Open as Smart Object in Photoshop: Embeds the raw file inside a Photoshop Smart Object layer. This enables you to double-click the layer thumbnail later to re-access the raw data via Camera Raw.
  • Open as Layers in Photoshop: Loads multiple selected images as individual layers in a single Photoshop document, which is ideal for focus stacking, exposure blending, or composite work.
  • Open as HDR/Panorama in Photoshop: Merges selected exposures or frames using Photoshop’s native rendering engines.

Performing Edits in Photoshop

Photoshop opens the image according to the parameters specified in your external editing preferences. At this stage, you can carry out tasks that go beyond Lightroom's non-destructive capabilities:

  • Advanced retouching and frequency separation
  • Complex object removal and generative AI fills
  • Multi-layer compositing and precision masking
  • Specialized filter application and pixel-level warping

Closing the Loop: Saving Back to Lightroom

To complete the round trip, the file must be saved back to the disk location from which it originated so that Lightroom can update its catalog.

  1. When finished editing in Photoshop, choose File > Save (or press Cmd + S / Ctrl + S). Do not use "Save As", as renaming the file or changing its directory breaks the automatic catalog link.
  2. Close the document in Photoshop (Cmd + W / Ctrl + W).

Photoshop generates the new TIFF or PSD file in the same folder as your original file. Lightroom immediately registers the new file in its catalog, typically stacking it next to the original raw file.

Re-Editing the Returned File

If further changes are needed after returning to Lightroom, right-click the newly created TIFF or PSD and choose Edit In > Edit in Adobe Photoshop. Lightroom will present three choices:

  • Edit a Copy with Lightroom Adjustments: Creates a new, flattened copy that includes any additional sliders you moved inside Lightroom since returning.
  • Edit a Copy: Creates a duplicate of the TIFF/PSD without applying new Lightroom edits.
  • Edit Original: Opens the exact TIFF/PSD file in Photoshop, preserving all existing Photoshop layers, layer masks, and smart objects. This is the recommended choice for continuing layer-based work.
