With posters and objects gathered from walls forming the main ingredient for his work, Dogançay's preferred medium has been predominantly 'collage' and to some extent 'fumage'. Dogançay re-creates the look of urban billboards, graffiti-covered wall surfaces, as well as broken or neglected entrances, such as windows and doors, in different series. The only masters with whom he compares himself are Robert Rauschenberg and Jasper Johns from the last heroic period of art, of which he was a part. Dogancay, however, has always preferred to reproduce fragments of wall surface in their mutual relations just as he found them, and with minimal adjustment of color or position, rather than to up-end them or combine them casually as in the Rauschenberg manner.
