If you're gonna save lossless, don't do it in PNG.
Do it in something like TIFF, PNG is optimized for flat areas of colors, hence the "Graphics" in "Portable Network Graphics". It's lossless, sure, but it's not the correct way to save photos or anything that's not a graphic lossless-ly.
Not to mention it's a waste of time in practice in the first place. Unless you're getting your images from the source and in PNG format, 95% of them are going to be saved in jpg or similar. Meaning saving in PNG won't suddenly make more information appear. You'll just increase file size with no benefit because PNG isn't a magic format.
It'd be like taking an MP3 and converting it to FLAC and expecting there to be more dynamic range.
For general purpose use, saving anything in JPG at high quality will be far more effective than saving in PNG. You're not saving over the image multiple times (in all likelihood, you won't save over it ever), so degradation won't occur, and 99% of the information is already there, and the 1% it's missing you would have never seen in the first place.
