Really good idea. How should the filter look like?
I mean it must be usable for someone without knowledge of boolean algebra and it must not take 10 mins. to set a filter to show pictures from you and me

Well - use the current Filter Wizard with a bit of minor (he he ) tweaking. Right now all filters are selected at once, which is a problem when creating more advanced filters. This would change the current approach with checkmarks next to the selected elements into a filter statement, that continually updates when the user selects different filters.

Something like this:

1. The user clicks 'Persons' and selects 'Henry'
   
2. The filter statement in the top reads "Persons = 'Henry'".
   
3. The user clicks the 'OR' button
   
4. The filter statement in the top reads "Persons = 'Henry' OR"
   
5. The user select Persons -> 'John'
   
6. The filter statement in the top reads "Persons = 'Henry' OR Persons = 'John'"
   
7. The user clicks the 'AND' button
   
8. The filter statement in the top reads "Persons = 'Henry' OR Persons = 'John' AND"
   
9. The user clicks the 'Delete last' button
   
10. The filter statement in the top reads "Persons = 'Henry' OR Persons = 'John'"
    
11. ... And so much later
    
12. The filter statement in the top reads "Persons = 'Henry' OR Persons = 'John' NOT (Persons = 'Michelle' OR Persons = 'Jackie')
    

Options should include 'AND', 'OR', 'NOT', '()', and 'Delete last'

For the novice user, this approach would still be easy. Finding all images with Persons = 'Mike' is still only one click away, and finding all images with Persons = 'Mike' AND Keywords = 'Baking' is actually easier than it is today. I do believe that even somewhat novice users would be able to predict the outcome of that filter statement.
