DESCRIPTION
|
|

|
|
- a new lighttable module "external editors", to select a program from a list of up to
|
|
- 9 external editors and run it on a selected image
|
|
- a set of lua preferences in order to configure name and path of up to 9 external editors
|
|
- a set of lua shortcuts in order to quick launch the external editors
|
|
|
|

|
|
|
* in the export dialog choose "collection" and select the format and bit depth for the
