Publishing software maker Adobe Systems has acquired privately held Fotiva, which creates digital photography applications. Santa Rosa, Calif.-based Fotiva's software allows people to manage, store, edit and share digital photos. Adobe's product line already focuses on image-editing software such as Photoshop. Fotiva, which was known as PhotoTablet until October, was founded in February 2000. Fotiva will become part of San Jose, Calif.-based Adobe's graphics business unit.
