The short version

  • Each has a real cost: Lensa the underlying Stable Diffusion model was trained on images scraped from the internet, including copyrighted artwork, without direct consent from the original artists, and Lensa avatar outputs have been criticised for replicating identifiable artist styles without attribution or compensation.; 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: Lensa covers Magic Avatars, RawTherapee covers Selectable demosaicing.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

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

Lensa

  • Someone wanting to generate stylised AI avatars from their own selfies, understanding those selfies are uploaded for AI processingnot RawTherapee
  • A user comfortable with the documented training-data provenance concerns around the underlying Stable Diffusion model choosing to proceed anywaynot RawTherapee
  • Someone wanting general photo retouching tools separate from the avatar featurenot RawTherapee
  • A user comfortable cancelling a free trial through phone app store settings before it converts to a paid chargenot RawTherapee

RawTherapee

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

Where each one falls short

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

Lensa

  • The underlying Stable Diffusion model was trained on images scraped from the internet, including copyrighted artwork, without direct consent from the original artists, and Lensa avatar outputs have been criticised for replicating identifiable artist styles without attribution or compensation.
  • Users and journalists reported the Magic Avatars feature generating sexualised images from ordinary selfies, including reported cases involving photos of minors, without the user requesting that style, raising documented concerns about model behaviour and safeguards.
  • Magic Avatars typically requires a separate one-time purchase on top of any Pro subscription, so the total cost of trying the feature is not covered by a single subscription fee alone.
  • The free trial converts automatically into a paid recurring subscription unless cancelled beforehand, following the same pattern of complaints about unexpected charges seen across comparable apps in this category.
  • Generating avatars requires uploading a set of personal selfies for AI processing; Prisma Labs states these are deleted after processing and not used for further model training, but this relies on the company's own stated policy rather than independently verifiable proof.

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

Lensa: Is Lensa Magic Avatars feature the same as photo editing?

No, Magic Avatars is a separate AI portrait generation feature using the Stable Diffusion model, distinct from the app's standard photo retouching tools.

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.

Lensa: Did Lensa face criticism over its AI avatars?

Yes, documented criticism covered the underlying model training data being scraped without artist consent, and reports of the feature generating sexualised images from ordinary selfies without the user requesting that style.

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.

Lensa: What happens to my selfies after generating an avatar?

Prisma Labs states uploaded selfies are deleted after processing and not used to further train the underlying model, though this relies on the company's own disclosed policy.

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.
