JPEG QualityThis should match the original quality of the image that has been photoshopped.Įrror ScaleMakes the differences between the original and the recompressed image bigger The results of this tool can be misleading, watch the video and read the tutoria for details.

This can make manipulated regions stand out in various ways.įor example they can be darker or brighter than similar regions which This tool compares the original image to a recompressed version. Blocks that have been rejected because they do not have enough detail show up as black. Can be useful to tweak Minimal Similarity and Minimal Detail. Show Quantized ImageShows the image after it has been compressed. Maximal Image SizeThe maximal width or height of the image used to perform the clone search. Minimal Cluster SizeDetermines how many clones of a similar region need to be found in order for them to show up as results.īlocksize (2 n)Determines how big the blocks used for the clone detection are.

Minimal DetailBlocks with less detail than this are not considered when searching for clones. Minimal SimilarityDetermines how similar the cloned pixels need to be to the original. If a lot of regions overlap the result can look white. Regions that are similar are marked in blue and connected with a red line. Note that this tool is a first attempt and not yet very refined. Has been manipulated using the clone tool. These can be a good indicator that a picture The clone detector highlights similar regions within an image. Histogram Equalization is the most robost option. Auto Contrast mostly keeps the colors intact, the others can cause color shifts. Histogram Equalization, Auto Contrast and Auto Contrast by Channel. MagnificationAlso known as the zoom factor.ĮnhancementThere are three different enhancements available at the moment. It does this by magnifying the size of the pixels and the contrast within the window.

The magnifier allows you to see small hidden details in an image. You can use this application while offline.

Just like a magnifying glass it can't tell true from false or good from evil,īut it might just help you to uncover the truth.Īlso absence of evidence is still not evidence of absenceĪnd Extraordinary claims require extraordinary evidence. It helps you to see details that would otherwise be hidden. You should think of forensically as a kind of magnifying glass. You can read a bit more about it in this blog post. It includes clone detection, error level analysis, meta data extraction and more. Forensically is a set of free tools for digital image forensics.
