Your post is not clear
I wanted to reset my iPhoto library and remove all places, faces and events recognized from the pictures, so I copied my iPhoto library to a hard drive and then deleted it and emptied the trash.
Copied the data to iPhoto again and took a look.
Exactly what does this mean?
Probably your best bet is to run your iPhoto library on an external drive
Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

Well, I didn't solve all the problem - I copied the iPhoto library to an external hard drive, pointed the new location to iPhoto, tested, moved the original library to the trash and emptied it. But I checked the activity monitor and found out that there were just 12,33 gigabytes of free space in my internal drive. It looks like I didn't empty the trash, but I did.

You dragged the iPhoto Library to the System Trash and emptied it? Click on the Trash icon on the Dock. What can you see?

Then your problem is Finder one, isn't it?

The problem was in Time Machine. You know those white and purple lines? The white ones are backups in the main drive (the internal drive and the purple ones are the backups inside the external drive, were all the data is stored in the end). Time machine does it in order to restore very recent files, so it won't need to do an entire backup to the external drive. After 2 days, the internal drive's backups are stored in the external drive and actually removed from the system. Now, the iPhoto library that I removed was really deleted, and, I think, tonight, the other copy of the library will be deleted.
Thank you for helping me with this problem.
