Oleg, you cannot add comments to an album. But you can add both a title and a description to photos, and to groups of photos. Go to the Photo Organizer (from the upper right). Click on the album on the left. Click on all the photos you want to edit one at a time (this puts a big white check mark on them), or use the 'select' drop down to select all. Then click the "Edit" button.
The photo are taken in Haifa, Israel - in the area affected by the big fire in the end of 2016. Presumably the fire was ignited intentionally...
The tool: our prototype dual-camera rig with two vertical Sony A5000 cameras.
Do you know how one can add comment to an album? I can only see the title field, but I prefer to keep it short.
It's in Nesher, Israel. Frankly speaking, the park where it stays isn't worth visiting. I went there to test the camera rig because it's close to my home.
