I have a folder of 700 images open in the import dialog. I want to select out specific images (056, 072, 310, 078, 511, etc) that the bride has selected for editing, and make a catalog. How do you search for a filename during import? I don't want to scroll through and hunt for them one by one because her list is not in numerical order.
Import them, select them, and then export as catalog (file menu).
You can not create a catalog from the import dialog box.
If you don't want them in the original catalog, simply delete them. Alternatively, you could create a new catalog, then import them into the new catalog.
An alternative approach that may be easier if you have just a handful of files to import: Create a new catalog in LR. In the Mac Finder / Windows Explorer, find the files you want to import and drag them into the LR library window.
