Photographic Memory vs. Eidetic Memory: Understanding the Science and Myths

What are the Benefits of Having a Good Memory?

Maintaining a good memory — especially as you get older — has numerous benefits, including enhanced cognitive function, better quality of life, and increased independence. 

Research shows that keeping your brain active with mental exercises, eating a balanced diet, and staying socially connected can all support memory and brain health. 

These habits may even help slow down age-related memory loss, allowing you to enjoy life and stay sharp as you age.

Can Memory Be Trained? 

While photographic or eidetic memory isn’t something you can develop, your memory is a skill that can be improved with practice. 

By using the techniques below, you can enhance memory recall and how well you store information. 

Use mnemonic devices

Mnemonic devices are tools that help organize and recall information by associating them with familiar patterns or visuals. For many, having a flawless memory would be incredibly useful — allowing you to stay organized, excel at work, and recall every detail with ease. 

Terms like photographic and eidetic memory are often used to describe this ability, but do they really exist? 

While photographic memory is largely considered a myth, eidetic memory — vivid, short-term recall — is well-documented, especially in children. 

In this article, we explore the science behind these types of memory, their key differences, and what you can do to improve your own recall skills. 

What is a Photographic Memory?

Photographic memory refers to the ability to recall an image, scene, or information with perfect detail, even years after seeing it. 

It’s often described as a type of long-term memory that works like a camera, capturing a moment exactly as it happened and storing it for future recall. 

This means being able to recall every detail — like the exact arrangements of objects, colors, or words on a page — without forgetting or distorting any of it. 

For example, a person with photographic memory may claim that they can vividly remember every word on a page long after closing a book. 

Does photographic memory actually exist? 

Many researchers question whether having a photographic memory is possible, but to understand why it’s disputed, it’s important to first understand how the memory system works. 

Memory relies on the brain’s ability to encode, store, and retrieve information. Visual details are processed in the visual cortex and stored as sensory impressions and meaning. 

However, memory is reconstructive, not exact — each time we remember something, it’s influenced by perception, context, and emotion. 

The brain prioritizes efficiency over exact replication and will discard unnecessary information to conserve mental resources.

Storing an exact copy of everything you see — which is the assumption with photographic memory — would be inefficient and overwhelming for the brain. 

The verdict

Due to the reconstructive nature of memory, there is little scientific evidence to confirm that true photographic memory exists. 

Many studies have tested individuals who claim they have photographic memories, but none have consistently demonstrated this ability under controlled conditions. 

While some people have exceptional memory skills, this is thought to be the result of learned techniques and naturally strong visual recall — rather than innate photographic capability. 

Eidetic Memory Explained

Eidetic memory — sometimes called didactic memory — is the ability to recall visual elements in great detail after seeing them for a brief period of time. 

Someone with eidetic memory is able to “see” the image, object, or scene as if it were still in front of them, and describe or reproduce it with remarkable accuracy. 

For example, they could look at a colorful painting of a garden filled with flowers and a small pond. After the painting is removed, they can “see” the image in their mind for a few minutes.

A person with eidetic memory would be able to recall the exact number of flowers and the shades of the petals — but this mental picture fades, and leaves only general impressions. 

Although it's often used interchangeably with photographic memory, eidetic memory is a short-term ability to recall visual details that last a brief moment and fade quickly. 

How does eidetic memory work?

Some researchers believe that eidetic memory may share similarities with a condition known as synesthesia — which could explain how this type of memory works. 

Synesthesia occurs when one sense, such as hearing, triggers another, like seeing colors. 

It’s thought that the heightened connections in a synesthete’s brain may allow for more vivid memory recall, similar to what’s seen in people with eidetic memory. 

People with synesthesia often have strong memory skills, which may explain a possible link between the condition and eidetic memory. 

However, more research is needed to better understand this potential connection. 

How common is eidetic memory? 

Eidetic memory exists most often in children, with studies showing that 2-10% of children between six and 12 may have this ability. 

As we grow older, the brain focuses more on language and abstract thinking, and the ability to recall vivid images fades. 

For adults, true eidetic memory is extremely rare, although some people’s strong visualization skills can be mistaken for it.

Photographic Memory and Eidetic Memory: A Side-by-Side Comparison 

The table below highlights the key differences between photographic memory and eidetic memory, making it easy to compare the two.

These techniques make learning more interactive and engaging, which improves memory retention. 

One simple example is the acronym, “ROYGBIV”, which is a great way to remember the colors of the rainbow. 

Creating similar mental shortcuts helps encode information in a way that’s easier to retrieve, engages different parts of the brain, and makes details easier to remember. 

Improve your lifestyle

A healthy lifestyle is vital to memory function — regular exercise, quality sleep, and a balanced diet work together to optimize brain health. 

Exercise increases blood flow to the brain, encouraging the growth of new neurons, while sleep consolidates memories, and transfers them from short-term to long-term storage. 

Incorporating nutrient-dense foods into your diet, like salmon, blueberries, and walnuts also provides essential vitamins and minerals for cognitive function.

The World Health Organization (WHO) recommends that adults should aim for 150 minutes of moderate-intensity exercise per week, which could include gentle hiking, jogging, or cycling.  

Similarly, adults are advised to maintain a consistent sleep schedule of seven to nine hours of rest per night.  

Practice mindfulness 

Mindfulness — the practice of being fully present in the moment — can strengthen your focus, and reduce stress, which are both essential for improving memory. 

Techniques like breathing exercises, meditation, or simply taking note of your surroundings can train your mind to encode and retrieve information more effectively. 

For example, 10 minutes of daily focused breathing exercises or using apps like Calm or Headspace can help reduce cortisol levels — a stress hormone that negatively impacts memory.

Practicing mindfulness during everyday activities, like eating without distractions or observing nature, can help enhance your overall mental clarity and memory recall. 

Minimize distractions

Constant phone notifications, noisy environments, or attempting to multitask can hinder your brain’s ability to focus and make it harder to remember important everyday details. 

Minimizing these distractions allows your brain to fully engage in encoding information, improving memory retention over time. 

A few simple strategies to eliminate distractions include switching off non-essential notifications, using productivity methods like the Pomodoro Technique, and creating a quiet workspace. 

Removing these interruptions can help you create an environment where your brain can work more efficiently, and enhance your ability to concentrate — leading to better memory retention. 

Focus on practicing and repeating information 

Regularly repeating information is one of the best ways to strengthen your memory. 

By using a technique called spaced repetition — where you review details at increasing intervals over time — you can help train your brain to store information more effectively. 

For example, if you’re studying for an exam, instead of cramming everything in one session, review it the next day, then a few days later, and again a week later. 

This method works with your brain’s natural forgetting cycle, making it easier to move information into long-term memory. 

Flashcards, apps such as Anki, and teaching the material to someone else are great ways to repeat and reinforce the information you’ve learned.
