If you really want to get some good pictures of the Eiffel Tower then you must wait until nightfall. A spectacular seen is when the Eiffel Tower aluminates. My suggestion is to snap your best pictures at the first lighting show. Pictures usually turn out better without glare from the light if it is nearest to dusk. Using a tripod will also help eliminate glare.
