It is one of the most visible choices in MurMur Picture Dictionary, and also one of the most debated: why real photographs, when most children’s apps rely on colourful, stylised illustrations?

A drawn carrot is not a carrot

A drawing, however lovely, is an interpretation. It simplifies, it stylises, it sometimes invents details that do not exist in reality — eyes, a smile, improbable colours. For a child building their vocabulary, that gap has a cost: the word “carrot” ends up linked to an imaginary object, not to the real carrot they will come across at the market or on their plate.

A photograph, on the other hand, does not cheat. A carrot is orange, textured, sometimes a little crooked — and that is exactly what the child will see off-screen. The word attaches to a faithful, transferable, useful image.

“Vocabulary is useless if it stays locked inside the app. Our goal is for it to come out.”

A primary school teacher’s perspective

In preschool classrooms, this observation comes up again and again: children name what they recognise in real life more easily than what they have seen in a drawing. Photographic picture books, long confined to paper textbooks, have always worked better for this early learning of vocabulary — it is that on-the-ground observation that guided the design of MurMur Picture Dictionary.

How we choose each photo

Every image is selected with the same standard: a neutral background, a sharp and clearly identifiable object, no distracting elements. Neither too polished nor too raw — just real enough for a two-year-old to recognise the object at first glance, and just refined enough to stay pleasant to look at, again and again.
