Sometimes we see photographs that make us think that they have been digitally manipulated. There is no easy way to do this unless you are an image manipulation expert or have a PhD in forensic image analysis. However, there is an image error level analysis tool that can give you some idea. Image Error Level Analyser compares the error levels of different parts of the image and if there is a significant difference, highlights them as being digitally altered.


The tool is dead simple to use and is based on the image forensic research by Neal Krawetz. To use the tool, simply upload any JPG file from the web and click submit. IELA will than show you the original image along with the analyzed image highlighting the areas with significantly different error rates. The possible alterations include changing the brightness, hue, saturation of the area or touching up colors.
