Show only photos without albums

Hello everybody, How are you?

I have now returned to the Mac OS platform and the only thing I haven't been able to solve yet

It's a photo issue. On Windows I always organized my photos by events in folders. I was easily able to bring them to the Photos app.

The problem is that now with the albums created I can no longer know which photos are without abuns so that I can organize them.

Do you have any idea what I can do?
