Real-world test: Long exposures with Panasonic G9’s high-res mode

Out-of-camera 80MP JPEG using the Panasonic G9’s high-resolution mode. Lots of detail, and some strange-looking pedestrians.

New to Panasonic’s G9 flagship is a high-resolution mode, which shifts the sensor by half-pixel increments eight times, and generates an 80MP final image. As with similar technologies from Ricoh and Olympus, it’s not necessarily recommended for scenes with moving subjects in them. But we thought we’d see if we couldn’t make it work.

You’ll notice in the above image, the pedestrians are sharply ‘ghosted’ in the foreground; this is due (obviously) to the eight exposures being taken, but also partially the 1/500 sec shutter speed. What if we purposely chose a slower speed, so that they would blur more naturally into each other?

These are only initial findings on a gray Seattle day, but we’ve got some interesting results.

For this situation, in order to get a proper exposure without either an ND filter or stopping down to diffraction-inducing levels, I figured I’d give 1/30 of a second a try. As you can see, there’s a little ‘repetition’ around portions of the pedestrians in the foreground and across the street, and while there’s lots of detail in the scene, you may want to just use the normal 20MP file for this one.

What if we go with a little longer of a shutter speed, though?

This looks to our eyes to exhibit some improvement. We overall found that a shutter speed between 1/4 sec and 1/8 sec gave a reasonably → continue…
