Check out my article about how to critique your own and other people’s photographs.
Suggest using the Rule of Thirds.
Note blown highlights and black shadows.
Point out lack of contrast.
Look for poor exposure (photo taken in shade where color tones are muted)
Suggest using sunlight as color enhancer.
Recommend the stimulation of the five senses in the photograph.
Okay, here’s a photograph to critique. Let me know what you think!
