This is an example of academic painting in the modern period that was categorized as Juste Milieu--that's French for middle ground. or the middling way. Subject matter was modern--this appears to be a father vising his son in a hospital ward. The painting style is academic with careful attention to perspective, naturalistic lighting, figures, clothing, objects, textures and surfaces. Experimenting with anatural colors or abstraction or skewed perspective would have been counterproductive to the narrative. Juste Milieu paintings often sentimentalized the subject or moralized about them. That was part of the allure. To do that effectively, artists had to pay attention to specific details that would appeal to audiences. The pallor of the boy's face, the line of identical beds with their young patients and the shabby clothing of the man establish the figures as part of the working class and the tender demonstrations of affection (notice the patient being embraced by a relative, the small group of visitors in the background, and the bright peeled orange on the table--citrus was expensive and a treat) were all reminders of the inherent nobility and essential goodness of the working class.
