When you choose a folder, album or smart album in the Library Navigator of the Sidebar, the Collection Inspector along the right side of Observatory’s window will display the metadata of the selected collection.
Towards the top, you’ll see an icon to help you quickly identify the type of selected collection. Next to it is its editable name and a lock icon. It allows you to lock the collection, to protect it and its contents against changes. If you marked the collection as a favorite, or archived it, then you will see an indicator here too.
Unless the collection is locked, you can edit all information presented in this inspector. If you made an accidental change, just choose Edit ▸ Undo (
The inspector is organized in sections. You can collapse sections you are not interested in. You can also reorder the sections, but putting your mouse cursor between the disclosure triangle and section title, and clicking/dragging the section up or down to another position.
You can assign a color label to your collection by clicking on one of these seven colored circles. The meaning of the different colors is up to you. For example, you could
Assign a color label to albums you have published online.
Use a color label for albums to indicate the progress towards processing the images contained within. For example:
Please note that Observatory does not support all these phases of image processing itself.
To remove the color label, click it for a second time.
You can assign a 1–5 star rating to your album by clicking towards the right of this label. Drag the stars towards the left to remove the rating.
This attribute may contain an arbitrary textual or numeric value of your choice. The search field in the Library Navigator lets you filter collections by this status attribute.
Tags, or keywords, are a good way to organize your collections. The search field in the Library Navigator lets you filter collections by tags.
You can add notes to each of your collections. With this inspector you can view and edit it. If you have selected it, you can even press
⌘F to search inside the note.
Albeit handy, there isn’t much room in the inspector. Choose Collection ▸ Edit Note… (
⌥⌘') to open a much bigger, resizable Dialog for editing the note. There you can also press
⌘F to search inside the note, or click the icon near the bottom left of the Dialog.
