RT to Blur and Darken Photo Background?

Is there anyway to blur and darken the background of a photo using the latest version of RT?

Googled using RawTherapee Blur and Darken Background and found “Select an area in RT, then darken, lighten, blur and desaturate” by dngimage Select an area in RT, then darken, lighten, blur and desaturate but mentions “That feature was on the locallab39 branch, but it was decided that the tool did not integrate well into the code and was too limited in functionality and so would not get merged”

Hope someone has a solution to do this with the latest ver RT.

Thanks

Depends what you mean by “the background”. RT has no local editing capability of the sort where you would either select the background or use a mask layer to affect only the background. If that’s what you want, try darktable or GIMP.
