Artificial intelligence (AI) has turned the world of visual creation on its head. In a matter of seconds, tools such as Sora, DALL-E or Stable Diffusion can produce images of impressive realism. But this power poses a major challenge: how do you know if an image is real... or entirely generated by an AI?
In this article, we'll help you develop a critical eye and recognize the clues that betray artificial creations.
1. Inconsistent details: the first sign to spot
AI-generated images are often perfect at first glance, but they hide anomalies in detail. Take a closer look:
- Hands and fingers are frequently misshapen, too long or too numerous.
- The eyes may be asymmetrical or look in different directions.
- Jewelry, buttons, glasses or accessories sometimes blend strangely into skin or clothing.
- Text (on a poster, T-shirt or billboard) is often illegible or distorted.
Tip: Zoom in on the image. AI excels at overall composition, but often fails with microdetails.
2. Strange textures and proportions
Another way of detecting a generated image is to observe its textures and proportions:
- Hair often appears blurred or blends into the background.
- Skin textures can lack pores, giving an overly smooth or plastic appearance.
- Body proportions may seem slightly "off", with overly broad shoulders or illogical perspectives.
These anomalies go unnoticed at first glance, but careful analysis reveals that something is "wrong".
3. Reflections and shadows never lie
AIs are still struggling to manage luminous coherence.
- Shadows can point in several directions at once.
- Reflections in mirrors or on glasses don't always match the scene.
- Light can appear to come from several incompatible sources.
Tip: Compare the direction of the main light and that of the shadows - a classic way of spotting a fake image.
4. Context: an often overlooked clue
Beyond the image itself, the context in which it is distributed can be revealing.
- An overly spectacular image without a reliable source? Don't trust it.
- A visual shared on a massive scale without photo credit or author credit? Another red flag.
- If the image is linked to a controversial or emotional news item, be extra careful: visual deepfakes are often used to manipulate opinion.
The human eye remains your best tool
Even in the age of ultra-realistic image generators, the critical eye remains the best defense. By taking the time to observe, analyze and cross-reference sources, you can unmask most artificial images.
AI is evolving fast, but human vigilance and visual culture remain irreplaceable.
