This page looks at the best possible results when using the Panasonic S1R Multi-Shot High-Res mode.
Comparisons include standard vs HighRes mode images at native resolution as well as resampled to 125 megapixels. Image can be toggled for A/B comparison. Observations on sharpness, noise, etc are made along with an estimate of the maximum possible gains.
It’s clear after doing this comparison and also looking at others that these examples represent a “best possible” scenario—all sorts of things can degrade HighRes mode. Indeed, these examples shown above are compelling, but others I shot were less so.
