ISO25600 from GX7

For those who may not be aware, there is a variation on this process of shooting burst to obtain multiple frames, stacking in PS, auto align, convert to Smart Object, and then select Median averaging mode.

If you hand hold, as opposed to using a tripod, you can add a step that sets the size of the images in the stack to 200%. This step is performed before converting the images in the stack to Smart Object, so just know that it can increase the time it takes to convert the images to Smart Objects significantly. Be patient, it's worth it.

The result is something that one writer termed "Superresolution", and was even profiled here on Dpreview.

The process makes use of the small camera shifts that come into play when hand-holding, using it to create a result somewhat similar to pixel shifting that has appeared in cameras such as the Panasonic G9, Sony A7RIII, etc. Except that unlike those modes, it not only works when hand holding, it needs the (hopefully small) movements to create the additional detail that makes this process so beneficial.

And it reduces the noise at the same time!

So if you'd like file sizes and resolutions that exceed what the m43 sensors are capable of on their own, try this technique. I've run several trials, both with a Panasonic G85 and a Sony A7RIII, and it really works.

If it's a worthwhile image, shoot more than one series of bursts. Out of something like a dozen trials, I've had one or two series that came out soft, probably due to excessive movement of the camera during the burst capture.

Here's the Dpreview link; note that the article also links the earlier article by Ian Norman on Petapixel.

Here's a link to my album on Flickr that contains a small assortment of images using this technique, both with the Sony & the Panasonic m43 cameras. These are downloadable, so you can compare them on your own computer screen. Please be sure to read the notes that accompany the individual images.

Some of the images are resized for 4K display, but there are one or two at full "super resolution".
