Adobe is a US company making computer software.
Its main presence in photography is through Adobe Photoshop, a proprietary, versatile image-editing program which competes with a variety of similar programs, including the most common non-proprietary alternative, GIMP.
Adobe Lightroom (a pun on "darkroom") is its application for managing and manipulating batches of digital-camera raw images.
