FZ 150 and noise editing..
That is a good question for a new photographer. Think of RAW as like a film negative. You don't edit on the negative, but rather during the printing. The idea is that the RAW file is a permanent storage medium for "all of the Digital data" capture by the camera, as opposed to a JPEG that is modified in camera and then the unused data is removed. (that is why jpeg files are smaller then RAW files, a lot of data is discarded after editing).
Now in Lightroom select your RAW file, right click and select create a virtual copy. Make all edits on the copy. Now what you are really doing is creating a data file with the information about the edits, not a whole new image file. When you go to save or export the file then you will need to decide what format to save it in. Your choices will probably be JPEG, TIFF, PSD (photoshop) or DNG (digital negative). JPEG is best for display on the internet or maximum compatibility when sharing with other people. TIFF, PSD and DNG retain more of the original information and hence are larger files.
This allows you to have your original file protected from changes, and then have multiple edits that you can save or export.
Now if you want to transfer copies of your RAW files to another program, then save as "Original" and it will create a copy of the RAW file that should be able to be imported into another program. If you are editing in in Photoshop or another photo editor you will probably need to save as one of the other file formats which will save with edits.
Just remember that RAW is all the digital information captured by the camera at time of exposure without any editing. When you edit, you don't change the RAW file at all, but create a sub data set that contains information about the edits and must be saved in one of the other standard formats. The RAW file never changes, regardless of the number of edits you make. All that changes is the data set. If you want to save the edit in a file format you choose one of the options JPEG, TIFF, PSD or DNG.
RAW is a permanent digital record containing all data, that doesn't change
All Edits are a separate data set (instructions) that tell how to create a new edit of the image.
You can have unlimited edits of the same basic RAW file, each unique.
You then export the edits into a standard photo file format.
You can create duplicate RAW files by saving as "original"
