What Causes the Green Dot?
The green dot in your photos is known as a lens flare. It’s a common occurrence in photography, not just with iPhones but with almost any camera. Here’s what you need to know about it:
- Lens Flare Explained: When you point your camera towards a bright light source, the light can reflect and scatter off the lens elements inside your camera. This scattering creates the green dot or sometimes a streak of light.
- Not Just an iPhone Issue: While we’re focusing on the iPhone here, it’s important to note that lens flare can happen with any digital camera. It’s not a defect or a problem with your iPhone’s camera.
User Experiences Across iPhone Models
Interestingly, this isn’t a new issue or exclusive to the latest iPhone models. Users have reported seeing the green dot on various iPhone models, from the iPhone 13 Pro to the iPhone 14. Here’s what some users have experienced:
- iPhone 13 Pro and Beyond: A user on the Apple Community forum mentioned a green spot appearing when taking photos towards light sources with their iPhone 13 Pro. This aligns with what we’ve seen in other models too.
- A Common Concern: Many iPhone photographers find this green dot annoying as it can affect the quality of their photos, especially when capturing moments with a bright background.

Technical Analysis of Lens Flare
Understanding lens flare in the context of smartphone photography is crucial. Here’s a simple breakdown:
- Lens Construction: The green dot, or lens flare, happens due to the way camera lenses are built. Multiple layers inside the lens can reflect light, creating that noticeable green spot.
- Comparison with Traditional Cameras: Unlike DSLRs, smartphone cameras have smaller lenses, which can make them more prone to lens flare under certain lighting conditions.

While capturing the perfect shot, encountering a green dot can be frustrating. But don’t worry, there are ways to fix it after you’ve taken the photo. For instance, Digital Photography Review offers great insights into post-production techniques that can help. Here are some tips:
- Photo Editing Software: Tools like Photoshop and Lightroom offer advanced features to reduce or remove lens flare.
- Snapseed for Quick Fixes: For a quick and easy solution, Snapseed’s healing tool is perfect for on-the-go edits.
Photography Tips to Avoid or Minimize the Green Dot
Prevention is better than cure, right? Here are some handy tips to keep that green dot at bay:
