Yes, Adobe Photoshop is a raster-based program. Images are created on the platform using pixels, and hence Photoshop is widely used for working with digital photographs. However, designers often choose to open and edit vector files in Photoshop. Editing vectors on PS has limitations, as they can only be worked with as a smart object or a rasterized file. Thus, if you are working with raster images, Photoshop can be an excellent tool to edit pictures and make photograph-based creatives.
