Fake Photo Or Real? Check If An Image Is Morphed Or Edited

6 in 10 people can’t identify a fake picture from a real one. Can you?
  1. We see hundreds of images every day, and almost all of them have been digitally manipulated in some way.
  2. Some have gotten basic color corrections or simple Instagram filter effects, while others have received full-on Photoshop jobs to completely transform the subject.
  3. It turns out humans aren’t very good at recognizing images that are morphed or modified. Quick tips listed in this article will help.

How To Tell If A Picture Has Been Photoshopped Or Doctored?

1. Digital Forensic Techniques

Fotoforensics.com is a good fake image detector website. It makes use of a technique called Error Level Analysis (ELA) to find parts of the image that are modified.

  • This is the original picture of a walkway clicked on my phone.
    Take a look at the ELA result, the edges have similar brightness and the textures have a similar color.
  • This is the modified/Photoshopped picture with a lion added to it.
    In the ELA result, look how the lion stands out with different brightness and color in comparison to its background.

  • Remember, if an image is original – Similar edges should have similar brightness, similar textures should have similar coloring in the ELA result.
    You can also try an altenative tool called Forensically.

2. Metadata or EXIF Data

When a digital camera captures an image, it appends a whole array of information like date, time, camera model, geolocation, etc., to the image file. This is called as metadata or EXIF data.

Imageedited.com uses this metadata to run a few analyses and tell you if an image is edited or not.

  • When I tested an edited/Photoshopped image.
  • When I tested an image downloaded from Facebook.

3. Reverse Image Search

Google reverse image search is a great way to find the original source of the image.

  • If your old Facebook friend posts an image from the swanky beaches of Bahamas, you can check if it’s authentic or Photoshopped.
  • Just drag & drop or upload the photo in the Google image search bar, and it will bring up all the sources of that image.

    It’s a great way to find out if someone stole an image from the Internet and posted it as their own.

4. Lighting and Shadows

Lighting and shadows play a pivotal role in finding if a picture has been morphed or doctored.

Begin by following the trail of light from its source in the image and determine whether the shadows and highlights are moving in the correct direction.

  • For example, light coming from the left side of an image will create shadows falling to the right.
  • Shadows and highlights will appear to violate the laws of physics when something has been removed or added to a photo forcefully.
    Irregularities or discrepancies in lighting and shadows are easy clues.

5. Careful Observation & Common Sense

Carefully looking over the image helps you verify the authenticity of it.

You might think that Photoshop scam artists might perfect their game but there are often visual tell-tale signs that a photo has been manipulated.

  • Check the minor mistakes: Even the best Photoshopped photos have minor mistakes which you can spot.
  • Look for patterns: Objects rarely repeat identically. A novice Photoshop user may well leave repeating patterns behind when trying to clone out an object.
  • Use common sense: “Aliens eating chicken tikka in a Chinese restaurant” is definitely a Photoshop fake.

The Fake Can Never Be Real

Imagine you go out and buy a brand new phone with beautiful packaging.
You bring it home and unbox it.
Try putting the phone back and box it. It will never be the same as the original packaging.

The same is true for a digital photo. Once you mess with it, it will never be the same again.
And that makes it easy to detect the modified or morphed pictures.
