The plurality of design approaches and working methods afforded by the postdigital has blurred the role of images within experimental architectural practice. Images as Instruments focuses on the image as a speculative medium for conceiving and perceiving architecture. By accessing and manipulating the information stored in images, digital image processing may be modeled in the form of multidimensional systems. Accordingly, the research explores new form-generating processes by deploying images as a generative instrument. Especially, raster-based image manipulation techniques were used to explore how they can inform three-dimensional implications, which invites a new vision for architectural conventions. Broadly, It is a critical inquiry into the meaning and role of image in our discipline and addresses the shifting ontology of image in the postdigital context.
