Originally posted by doroth2 I do have one other question. If I decide to purchase the stand alone version of Lightroom, how do I switch from one to the other? Do I need to uninstall the version already on my computer? What happens to the photos I've already edited? How does that work?
You have three parts to this:
Lightroom the software
The Lightroom catalog
Your images
Your images stay separate so that does not matter, just keep those files in sub-directories all under one directory like"Pictures" or "Photos".
The catalog can also be passed between versions, even between Mac and PC with no issues. Just make sure you know where yours is located and where the backups are.
The software AFAIK can have both versions installed with no issues. Not sure about the trial version though. I went from standalone to CC version and had both versions installed for a while. Just run the executable for the one you want. Though obviously running two versions at the same time is confusing and not recommended.
Your edits, assuming you edited the RAW files are saved in the catalog. Unless you export to jpeg in which case the edit is baked into the jpeg.
