Hi Gillian, I don’t think that is available yet on the iPad. However if photos have been sync’d and you have access to a computer e.g.in a hotel whilst on assignments you can add titles and captions in your LR Web Space.
Log-in at the link below to see your stuff in the Creative Cloud.
Thanks for the reply. I was beginning to think there was no answer! I will have a look at the link you sent. And also web space??
Your images first need to be imported into Lightroom running on a desktop or a laptop. Images you want to see and/or work on with Lightroom Mobile get placed in a collection which is synced to LR Mobile. You can then view the collection with a web browser and add a caption or title to the optic. I believe those are your only options right now.
Thanks Theresa for your comment. Yes seem to be my only option. Not ideal, as it sounds like I need to go out and buy a laptop for when I am on assignments.
