When you come across a photo on your iPhone with parts obscured by a black marker, it may seem impossible to uncover what’s hidden beneath. But with the right techniques and tools, it’s possible to see through that black marker and reveal the concealed content. Let’s dive into the steps and tips that will help you achieve this.

Understanding the Basics

First things first, it’s crucial to understand the principle behind this technique. When you apply a black marker on a photo, it doesn’t necessarily make the underlying content permanently invisible. With the right adjustments in brightness, contrast, and other settings, you can decrease the opacity of the black marker, making the hidden content more visible.

Step 1: Open the Photo in the Default Photos App

Begin by locating the photo you wish to edit. Open it in your iPhone’s default Photos app. This app comes pre-installed on all iPhones and is typically the easiest and most accessible tool for this task.

Step 2: Tap ‘Edit’ to Access Image Editing Tools

Once you have the photo open, tap on the ‘Edit’ option, usually located in the top right corner of the screen. This will bring up various editing tools that you can use to manipulate the photo.

Step 3: Adjust Key Settings

To see through the black marker, you’ll need to adjust several settings:

  • Exposure: Increasing exposure can lighten the overall image, including the blacked-out area.
  • Brilliance: This enhances the brightness and details in the darker areas of the photo.
  • Highlights: Adjusting highlights can help to bring out details hidden under the marker.
  • Shadows: Decreasing shadows can make darker areas lighter, revealing what’s underneath the black marker.

Why These Adjustments Work

These adjustments work because they change how the light and dark areas of the photo are displayed. By altering these settings, you can reduce the intensity of the black marker, making it semi-transparent and allowing the underlying content to become visible.

Limitations and Considerations

It’s important to note that this method may not always be effective. The success of these steps largely depends on the thickness and opacity of the black marker used in the photo. Additionally, over-editing can lead to a decrease in image quality, so it’s crucial to find a balance.

Ethical Considerations

Before attempting to see through black marker on a photo, consider the ethical implications. If the content was hidden intentionally, think about privacy and confidentiality issues before proceeding.


Seeing through a black marker on your iPhone is a fascinating exercise in photo editing. While it may not work in every scenario, understanding and applying these steps can be quite rewarding and enlightening.


  1. Can this method work on any iPhone model? Yes, as long as your iPhone supports the latest version of the Photos app.
  2. Is it possible to see through very thick black marker? It can be challenging if the marker is extremely thick, but adjusting the settings as described may still reveal some details.
  3. Does this method require any additional apps? No, the default Photos app on your iPhone should suffice.
  4. Is it legal to see through blacked-out information in photos? Legality depends on the context and purpose. It’s important to respect privacy and legal boundaries.
  5. Can these techniques damage the original photo? No, the original photo remains unaltered. Any changes you make can be reverted by simply undoing the edits.
