I use a 4k screen - hence the x and y values with all that screen real estate I can get a clear view of the thumbnails in Opus and the metadata panel.. Apzemek was looking for ideas to get him started on a macro. My macro is not a general image-tagging macro, but one designed specifically for the way I work.
It was never designed to work as Apzemek seems to want his to work. The idea is that you select a number of images and add whatever tags you need to those images. If I take 20 pictures of the same area, I can add copyright info to all of them, probably add the same caption (description) metadata. The macro will put whatever you type into the form into the metadata of ALL the selected images. I can add or amend metadata to individual images later.
If you select more than one image, you will note that t he rename facility will cease to work. I only use it to rename individual images, preferring to use the terrific Opus rename panel for multiple renames
Keywords I treat entirely differently. Of course they can be added through the macro - which I sometimes do, but I have a separate system based on a series of toolbars to add keywords to images.
As for using the indexing service, it is a breeze, and as I have said, blindingly fast:
Will get you started on the syntax for searches - you can write a macro to do it also - and you set up the indexing services via the window's control panel. But, be aware, you cannot easily index mounted volumes, though that does not bother me, the way I work.
Please tear the macro apart at will to make it do exactly what you want. I provide it only as an idea for a starting point.
In the metadata game it really is a case of "Whatever gets you through the night".
