How do I export what I have edited in my the develop module? It is a long exposure of the milky way, I've softened the image to reduce noise in the develop module, but the library module (that I use to export) is showing significant more grain. How do I change this? How do I get the export option to work with what Ive edited in the develop module???
First Export the image, which can be done from the develop module by right clicking on the image and select Export. Then take a look at it.
The Library module works from a Preview file and some times that preview image isn't updated right away.
Why not exporting and looking if the "significant more grain" is not simply an impression you have when looking at a scaled down version of your image. Anyhow, to appreciate your picture grain, you need to look at the picture with the 1:1 view.
If after the export (and looking at the exported image at a 1:1 scale) the grain is still significant, post screenshots of your one to one views.
Do not forget to mention your LR version and OS and version.
