I asked ChatGPT to analyse these two images for composition, technique, and content. I then asked to assess which is the ‘best’ version.

Portobello, Market, 2018.

Portobello, Market, 2018.

ChatGPT: Let’s delve into the analysis of these two images:


  • Both images feature the same subject—a woman in a street market setting—but each with a different compositional approach.
  • The first image is in color, which brings out the rich textures and varying shades present in the scene. This gives a vivid sense of the market atmosphere. The woman is placed off-center, adhering to the rule of thirds, which often results in a more dynamic composition. She is captured from a slight side-angle, indicating motion or progress.
  • The second image is in black and white, which strips away the distraction of color and emphasizes shapes, forms, and textures. The composition here is more central, with the subject directly facing the camera, creating a sense of confrontation and immediacy.


  • The color image has a shallow depth of field, keeping the woman and her immediate surroundings in focus while blurring the background. This technique helps the viewer’s eye to settle on the subject.
  • In the black and white image, a higher depth of field would have been used, given that more of the scene is in focus. It appears that a faster shutter speed may have been used, as the motion is more frozen in time compared to the color image.
  • The conversion to black and white can be a technique in itself, as it requires the photographer to consider the tonal range and how it will translate from color.


  • The subject’s expression and posture are central to the content of both images. In the color photo, her pose is more relaxed, and her expression is contemplative. The contents of her shopping, the phone in her hand, and her stylish attire suggest a narrative about modern life intersecting with traditional market culture.
  • The black and white image, due to its higher contrast and starkness, gives a more dramatic feel to the scene. The expression seems more intense, possibly because color does not distract the viewer, and the contrasts of light and shadow play a more significant role.


  • The “best” image depends on what the photographer intends to convey. If the goal is to present a slice of life with a rich, textured backdrop, the color image may be preferred for its vibrancy and the story it tells through color and detail.
  • If the intent is to capture the mood, character, and form, the black and white image does this effectively. It brings a timeless quality to the image, focusing on the subject’s expression and the play of light and shadow.

Each image has its own merits, and the best one is ultimately a subjective choice based on the viewer’s preferences and the intended message of the photograph.

Which expresses the woman’s character ‘best’?

ChatGPT: The expression of character in a photograph can be subtle and complex.

This is influenced by elements such as composition, lighting, and the subject’s demeanor.

  • The color image provides context. We see her in a vivid, real-world environment. The details like her chic attire, the way she holds her belongings, the act of checking her phone—all contribute to a narrative about her character. She appears to be a modern, perhaps sophisticated person who is comfortable in an urban, dynamic setting like a market.
  • The black and white image, however, strips down these external contexts and focuses on the woman’s face and expression. The high contrast and dramatic lighting contour her features more sharply, potentially conveying a sense of strength or intensity. This can suggest a different aspect of her character, highlighting her presence and poise.

If you’re looking for a portrayal that speaks to the subject’s interaction with her surroundings and her role within them, the color image might be the best expression of character. If, however, you’re looking to capture the essence of the subject’s inner self or a more emotional and psychological portrayal, the black and white image might be considered more expressive of her character.

Personal interpretations of these nuances will vary among viewers, and some might argue that neither image can truly capture a person’s character, which is multi-faceted and cannot be wholly represented in a single moment. However, each image offers a different facet of her character, either defined by her environment and lifestyle or by her individual presence and bearing.
