Aka pixel shift stitching

Method

There are numerous tutorials providing instructions for creating a super resolution image in Photoshop – this one by Ian Norman on PetaPixel is among our favorites. Distilled down to its simplest terms, there are four easy steps:

Bring all images into Photoshop as a stack of layers Resize the image to 200% width and 200% height using 'Nearest Neighbor' Auto align all the layers Average the layers by setting each layer's opacity to 1/layer number (the 1st layer will be 1/1 so 100% opacity, the 2nd layer will be 1/2 so 50% opacity, and the 4th layer will be 1/4 or 25% opacity, and so on). Sharpen the image using a Radius setting of 2, and a suitable Amount setting (we used 200% for the 4 image stack and 300% for the 20 image stack – the more images you stack the more amenable the composite will be to aggressive sharpening)

Alternatively, for the fourth step you can convert all layers to a 'Smart Object' and change the stacking mode to 'Median'. This can help deal with ghosting from movement in your final image, but can also take longer to process.

Finally, you can resize the final output by 50% width and height (we prefer Bicubic resampling for this step) to get the shot back to its original resolution, but with far more detail and cleaner output. Or, you can opt to save the high-resolution file if you print big, but just keep in mind that for a 36MP camera, that's a 144MP file. You can always re-upscale a super resolution file you've shrunk, and if you use the 'Preserve Details 2.0' resampling method in Photoshop to do so, the results are often impressive and sometimes hard to distinguish from the higher resolution super resolution file.
