I have two CC accounts through work, which is shared across several computers, including my laptop.
I would like to use Lightroom semi-privately, but do not want my colleagues who also use the CC products to be able to see my personal pictures.
Is it possible to store the uploaded photos in a "private" account, or have it that they are not available to be seen across all devices?
1. Use semi-privately: if you are sharing an account with other people, then you are sharing one single catalog. There's no way to hide a portion of this.
2. Not seen across all devices: no.
