   ledwall.ems.srl — forma propria della pagina
   Volume di ricerca piccolo e costo per clic il piu' alto dell'account: ogni
   clic sprecato qui costa il triplo, quindi la pagina deve rispondere alla
   paura entro la seconda schermata. La paura e' visiva ("con le luci accese
   non si vede niente"), e per questo la colonna portante e' una PROVA A
   SCHERMO: due riquadri affiancati che mostrano cosa succede al contrasto a
   parita' di luce in sala. Non e' una fotografia e non finge di esserlo: e'
   uno schema, ed e' scritto sotto.
