Compare dpi when selecting duplicate photos #851

Open caitsmommy opened 3 years ago

caitsmommy commented 3 years ago

I have over 11k duplicate photos in only 1 of my drives and I want to keep the the photo that has the best resolution. The details does not have an option to add different properties for easy comparing when selecting duplicates. I currently have to open containing folder of each picture, select properties of picture and look at the details tab to view dpi of each photo. This is extremely time consuming. The ability to view horizontal resolution and vertical resolution (dpi) with the details would be much more efficient. Doesn't matter if its in the result details or if it could be an option in columns. I have no programming experience so I apologize in advance if this is already able to be done.

Thank you so much!

Where do you get these DPI values from? Are you talking about EXIF tags? If you are talking about EXIF, then it is not reliable as the values can be spoofed to be anything, or entirely missing, so it's probably not going to be very useful. Or is it a value stored in the JPEG metadata (JFIF)? Seems to be the same problem as EXIF.

We already have image resolution (displayed in the details panel) which should be enough. DPI only applies during scanning of documents, it does not apply to (static) images, for which only the resolution is relevant to us. I might be misunderstanding something, but I doubt DPI means anything here. Correct me if I'm wrong.
