A very good extension, good to have - can be improved.

This extension is a very good RAW developer to have for the photos app. It works great with many (but not all) lighting situations.
It does a fantastic job with lens correction and noise reduction. Smart lighting and haze removal work, as mentioned, with many but not all photographs. I use it as a first step before passing the image on to other extensions. Disadvantage here (and that is Apples’ fault!!!) is that one can not save TIFF images.

I am not sure why it can not do lens correction after the photograph has been worked with in other software and all the exif information is still intact? DXO does in many cases not recognize the camera/lens used after the photo has been altered. I do understand that fringing may not be corrected in this case (and therefore DXO does not make it available), but the lens distortion correction should work. Having this available would allow this extension to be used at the end of the workflow, if smart lighting and other features are not required as a first step.

What is missing:
- Histogram with highlight/shadow indicator
- loupe or another form of zoom-in tool
- fine adjustment slider for smart lighting/noise removal & clear-view

I do hope they will expand upon this extension and integrate more detailed and sophisticated tools.

I am glad I bought it as US $ 10 is a very good value.
