Visual Similarity Duplicate Image Finder uses advanced algorithms to find similar images in a way that a human does. Due to that fact it can find similar images even if they are in different image formats, different bit depth and image sizes.
It seems I have a thing for liking simple types of fonts. This type puts the word into use by making everything outside of the "focus" circle blurry and everything inside of it super sharp and easy to read. The circle acts as a view finder for cameras as well when you have to line up the center circle to create a crisp image.
