I changed the size of a JPG of a photo that still contains the original EXIF data. How can I calculate the original resolution (in pixels) that the camera was set to when taking this photo? In EXIF, I see the following potentially relevant information:
EXIF: Model NIKON D850 XResolution 240 YResolution 240 ResolutionUnit inches FocalPlaneXResolution 2301.324615 FocalPlaneYResolution 2301.324615 FocalPlaneResolutionUnit cm FocalLength 78.0 mm FocalLengthIn35mmFormat 78 mm XMP: CropTop 0 CropLeft 0 CropBottom 0.932059 CropRight 0.932058
Can this data be used to derive the resolution with which the image was originally taken?
