    anyone been playing with this? it's an additional feature in camera raw which will double the raw file on both horizontal and vertical axes, and gives better results than using photoshop standard resizing - basically adding ML resizing (though fixed to doubling on each axis) which hadn't been available in PS.
    on my 5 year old system, the standard resizing takes about 5 seconds, but this option takes several minutes and outputs a new DNG file.

    funny thing is, on the first file i tried it on, i think the 'traditional' method worked better; the slight jaggedness on the resize actually makes it look slightly crisper.

    apols for the large images; i deliberately chose one that would require upscaling; original was shot at 300mm on the cheap sigma 70-300mm lens. 12MP.
    first shot is the full frame, then the standard resize, then the new resize.

    I meant to have a look at this the other night, thanks for reminding me.

    100% crop comparison of your image.

    I agree, to my taste, the old method looks sharper.

    Please forgive me, but what exactly is the abbreviation ACR? And is it available on a Canon 5D MkIII, or a Nikon D850?


    Thanks.

    it's Adobe Camera Raw, so not specific to a camera. comes with photoshop.

    Looks to me when viewed at 100% there's some noise reduction thrown in, the new one definitely looks softer, but with less noise.

    When looking at it from a distance, it's evident that the latest one seems less and less obvious of a distinction, but in after, all models appear nearly clear but a bit dim.

    Here's my quick test. The image is a severe crop from a 24pm RAW at ISO 100 (Sony A7iii). I didn't do any other processing other than the default that ACR does opening Sony RAW files.

    Good light and low ISO, so noise isn't a factor. I think there's a little more detail in the Super Resolution version. Edit: actually, if you look at them at 100% (on a desktop/laptop) the Super Enhanced version is a fair bit sharper and more detailed. See side by side at the very bottom.
