The short version

  • Only RawTherapee has a free tier, so it costs nothing to try first.
  • Each has a real cost: DxO PhotoLab optical modules exist only for camera and lens pairs DxO has measured, so owners of new, niche or adapted lenses either wait for a module or lose the main reason to buy the product.; RawTherapee there is no catalogue, only a folder browser, so any library management, keywording or search has to happen in a separate application.
  • They diverge on capability: DxO PhotoLab covers Optical modules, RawTherapee covers Selectable demosaicing.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

DxO PhotoLab

  • Rescuing wildlife or indoor sport frames shot at ISO 12800 where noise is the limiting factor rather than exposurenot RawTherapee
  • Correcting a known-soft zoom at its weakest focal length using a profile measured for that exact body and lensnot RawTherapee
  • Running a denoise and optical correction pass, then exporting linear DNG into an existing Lightroom or Capture One workflownot RawTherapee
  • Owning an editor outright rather than adding another monthly subscription to a small studionot RawTherapee

RawTherapee

  • Difficult raw files where the demosaicing algorithm visibly changes the result, such as fine fabric, foliage or architectural detailnot DxO PhotoLab
  • Archive and restoration work where a free tool with strict colour management is preferable to a subscriptionnot DxO PhotoLab
  • Photographers who want to understand and control each processing stage rather than accept a vendor renderingnot DxO PhotoLab
  • Producing a high quality sixteen bit TIFF to hand to GIMP or another editor for compositingnot DxO PhotoLab

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DxO PhotoLab

  • Optical modules exist only for camera and lens pairs DxO has measured, so owners of new, niche or adapted lenses either wait for a module or lose the main reason to buy the product.
  • DeepPRIME and DeepPRIME XD are heavy on the GPU, and exporting a few hundred frames on an older machine takes long enough that batch work has to be scheduled rather than run between shoots.
  • The library indexes folders and holds no central catalogue, with no cloud sync and no mobile application, so it does not replace Lightroom for photographers who manage a large archive across machines.
  • There are no layers and no compositing, so any retouching beyond local adjustments means a round trip to Photoshop or Affinity Photo and a second set of files.
  • Most major versions are paid upgrades released roughly annually, so the perpetual licence costs more over five years than the headline figure suggests, and skipping versions eventually loses support for new cameras.
  • Getting DeepPRIME output into another editor requires exporting linear DNG, which produces large intermediate files and roughly doubles storage for any frame processed that way.

RawTherapee

  • There is no catalogue, only a folder browser, so any library management, keywording or search has to happen in a separate application.
  • The default rendering is deliberately neutral and looks flat next to the camera JPEG, which means every user has to build their own processing profiles before the tool is pleasant to use.
  • Support for new camera models and for Fujifilm X-Trans sensors arrives later than in commercial converters because it depends on volunteer work and upstream library updates.
  • The interface presents several hundred controls across many tabs with little guidance about which ones interact, and the learning curve is measured in weeks rather than hours.
  • Batch export is slow compared with commercial converters and there is no GPU acceleration, so processing a large wedding shoot ties up the machine for a long time.

Answered from the vendors’ own pages

DxO PhotoLab: Is there a subscription?

No. Essential and Elite are one-time purchases. New major versions are separate paid upgrades.

RawTherapee: Does RawTherapee support Fujifilm X-Trans files?

Yes, but support arrived later than in commercial converters and results on fine detail still trail Capture One and Adobe on some bodies.

DxO PhotoLab: What happens if my lens is not supported?

You still get the editor and DeepPRIME, but not the measured optical correction for that combination. Check the supported list for your exact body and lens before you buy.

RawTherapee: Can it replace Lightroom entirely?

It replaces the develop side. It does not replace the catalogue, so you will need digiKam, darktable or something similar alongside it.

DxO PhotoLab: Can it replace Lightroom entirely?

For processing, often yes. For cataloguing across drives, cloud sync and mobile, no, because PhotoLab has none of those.

RawTherapee: Are my edits stored in the raw file?

No. Edits are written to sidecar profile files next to the raw, so originals are untouched and profiles can be copied between images.

DxO PhotoLab: Does it handle Fujifilm X-Trans files?

Support for X-Trans sensors arrived in recent versions, but coverage of individual bodies still depends on DxO releasing modules for them.
