The number is correctly 450, the next smaller number is 500. Now looking at the caption, the number 400 is detected,Īt the next smaller number, one does not know if it is 410 or 450? With the option Raw-Details and Super Resolution zebras are resolved about 16% higher.Ģ) ACR developed with the Raw-Details optionģ) ACR developed with the Super Resolution option In the second image with ACR and Raw-Details, the stripes have a resolution of 220LP/mmĪnd the third image with Super Resolution also shows a maximum resolution of 220LP/mm but much higher contrast. In the first image, with normal development using Adobe Camera Raw (ACR),Ī resolution of about 190LP/mm can be seen. If you look at the stripe lines (resolution) in the following images, That's why the stripe pattern is also well recognized and cleanly displayed by the resolution test target. The Artificial Intelligence (AI) knows only one animal, the zebra. The following comparisons are with the same RAW file, Ironically, it looks from Guppy's results that one thing ACR did not train very heavily on was charts of resolution bars! But that is demonstrably not the case, as discussed at and the many articles that it links to. You might think, for example, that an automatous vehicle vision system trained to recognize STOP signs would be paying attention to the shape, color, and letters. I expect this product is typical of most machine learning results, where even the creators don't know what the thing is actually using for clues while it's producing its result. Whether that actually happens is a matter for experiment. On the other hand, it may be perfectly willing to provide results that look like details that were lost to diffraction. I expect it will work really well, or not so well, depending on how your subject matter matches the patterns that their machine learning system was trained on.Īs a matter of principle, no, it cannot recover details that were lost to diffraction. My version of a short explanation is that this feature is in the business of recognizing low-resolution versions of things that it knows about, and turning them into cleaner high resolution versions of the same things. To my eye, it gives a good description of Adobe Camera Raw's "Super Resolution" feature. ![]() When developing with Camera Raw, the image should not be sharpened! When the frames were developed with the Super resolution. These images (TIF 7360x4912 pixels) were stacked with Zerene.) The resolution of the object is not reduced in the image. Were reduced to the original size (7360x4912 pixels) and converted to TIF format, (The frames in DNG format with the size of 14720x9824 pixels, When the frames were developed with the Super Resolution option. The following is the unprocessed section from Zerene Stacker, Now the "optimal" processing of the image without Super Resolution. Maximum resolution of 7360x4912 at 14bit color depth, ISO 64 recorded.ĭifferent is the development of the RAW images.Īnd for comparison with Camera Raw 13.2 with the Super Resolution option.įollowing is a section of the unprocessed image from Zerene Stacker without Super Resolution. Now we are talking about the same shots in RAW 14Bit format with the Nikon D810Īnd the Rodenstock Apo-Rodagon-D 2x 75mm 1:4.5 at an image scale of 3:1, It will have to be seen how well this simple and quick to accomplish option of Super Resolution, proves itself in practice. The most successful way to increase resolution is to apply Super Resolution to RAW images. With normal development, maximum sharpening and contrast enhancement, such a high resolution can never be achieved. (You should not use the default setting for sharpening in Camera Raw. The image with the super resolution is about 10% -20% higher resolution, but shows sharpening artifacts. Here I then reduced the resolution back to the original size (7360x4912). The image is then twice as large with the edge length, so 14720x9824. Recorded with the camera as RAW with maximum resolution of 7360x4912 at 14bit color depth, ISO 64.įirst the RAW image optimally sharpened during development:ĭeveloped the following image with the new "Raw Details" option:Īnd following developed with the "Super Resolution" option.

One of them is "Raw Details" and another one is "Super Resolution". Adobe is giving the new Camera Raw 13.2 some new options.
