Can anyone recommend a really good duplicate image finder that can compare some 100gb of photos by metadata e.g. exact date and time taken of the original photo rather than the name of the photo (as some of my photos might have different names after I changed them but they are the same photos).
Also is there a way of seeing a visual depiction of all the photos taken in a heat map style so I can see where there are large gaps (e.g. 1-2 months) where no photos are?
Also I am capable of doing a google search myself so what I am really looking for are recommendations based on what people have actually used and not opinions based on what they have read on a web site (as I capable of reading a blurb too). Thanks.
