Photodysmorphia
Either when (a) a professional photographer is overly critical of their own work which is viewed as being excellent by others or (b) an amateur photographer sees their work as great (typically due to excessive use of photoshop or filters, etc) when in fact it is of low artistic and technical quality.
Ever since Terry started playing with Instgram filters and Photoshop, he thinks he has suddenly become a professional photographer, in reality, he has photodysmorphia.
