There is a number of questions before anyone can give you any answers.
How did you import your photos from iPhoto? Did you use the plug-in in Lightroom? Do you know where all your photo files are on your harddisk?
You can always make a new Catalog in Lightroom and try to run through the import process again. Yes, you can rename all your files within Lightroom. Select the photos you want to rename and press F2.
No idea what you mean by location!!
Does the timezone matter to you?
How did I import the photos? I utilised the Import button on the left-hand side of the Lightroom startup screen.
Do I know where all my photo files are on my hard disk? Good question. All seem to be in the Pictures folder, with iPhoto images a subgroup.
New Catalogue in Lightroom? Ohhh that sounds a brilliant suggestion. Will give it a try right away.
Location - not too dramatic an issue - we can forget this. Just that somewhere in the zillion pages I was scanning through, there was a default setting of the USA, and the option to change - so I thought I'd put my accurate geographical location. It didn't work, I'm cool.
Timezone - It kinda mattered in that I feared that the technical help one of Lightroom Chat staff recommended I connect with ... only work Monday - Friday between 8 am and 9pm.. and I got confused about whether I'd be able to connect up around my working day. I didn't realise the time difference between PT and GMT. But as you have answered my question, no longer an issue... for now! I'm sure I'll be back, crying over another error I'll have made.
I will suggest that you use the plug-in in Lightroom to make the transfer from iPhoto.
1. In Lightroom make a new catalog
2. in Lightroom select the menu "File" / "Plug-in Extras" / "Import from iPhoto Library"
3. Follow the instructions on your screen and be careful to read it ALL !!!
This way you will get more information into Lightroom from iPhoto.
