Will daylight light bulbs used at night make 400 Asa on ORWO N74? It only is rated as 250 Asa in Tungsten, but 400 Asa in daylight!

It really won't make anything anything-- the film stock ASA is what it is. That said, yes, a BCA will give you more spectrum towards daylight (as would a Kino or an HMI and an LED) and therefore you would treat it as a 400 speed stock if that's your predominate lighting
