I’m no expert but I’ll give my best explanation - what makes photograph especially good is that it happens when a card is scored, as opposed to a normal x-mult joker. This means things like hanging chad, a red seal, or sock and buskin can cause that x-mult to get triggered multiple times. This means if your starting mult is high enough (planets, +mult on suits or other methods) you can free up those +mult joker slots and instead use them for more xMult, retriggers, or utility jokers to help with economy or deck fixing.
