Exact idea as with sound was dedicated to that subject and I found this subject on DT faster then when I was looking for some sound photos. This subject opposite to sound sense is easier to show in a photo then in illustration I think. So at first I show some illustration that matches my idea not as obvious as smelling flower.
I found some incredible smoke illustration with colorful vibration,
obvious but very charming illustration of woman smelling morning coffee in very simple form and brown color,
and very obvious but beautiful photo of childe smelling flower.
