Scince two days I have a laptop as second operating base (until now I only use a Desktop PC). I installed Lightroom 5 (trial) and want to know how I can see/view the history of my raw images on my laptop which i made on my desktop. I did not connect my new laptop with my desktop, don't even know if this is possible.
You need to transfer the catalog along with original images from your Desktop to Laptop in order to see the edits that you did.
If you are looking to share your catalog between the two computers on a regular basis, your best bet is to put the images and catalog on an external drive and move the drive from computer to computer as needed.
