Ran into a very interesting phenomenon pointed out by my wife. She was working in the yard and saw these long strands of moving stuff. (tech talk here) Never saw anything like it. Turns out it was tens of thousands of Gnat larva on a migration.
I wanted to get a shot of the larva to help identify it. Grabbed the GH5, my Leica 45mm Macro-Elmarit f2.8 lens, and a small tripod and was having no success. Even at 6400 ISO I couldn’t get a sharp photo of the moving, writhing masses due to the macro lens and speed with which the larva was moving.
I decided to try the Post Focus Photo Mode just to see if it could help. The photo mode uses all 225 focus points in the camera and captures them in a 6K video. Each of those 225 frames can be pulled and processed into an eighteen meg-pixel photo. The intended use in the beginning was to allow the user to decide which focus point to use later. An addition to the mode is the ability to fuse all the frames together giving you just the sharpest bits. The beauty is this can be processed in camera. Focus stacking in camera! Able to give you a 50MB plus file.

Even though this was a moving mass because each focus point is being photographed separately it is stopped and in focus. When all the images are processed together I get a Depth of Field i couldn’t with a single capture it also processed the sharp areas into a still image even though there was lots of movement.
Single capture of the same general subject.
The new technology can be leveraged in many ways to make it possible to create images in a different way.
Let’s look at some more examples of using the Post Focus Photo Mode (see part one here).
The focus is all throughout the image. Detail works in this case.
With the post focus mode used to capture this image there is still a soft bokeh even though the camera used every focus point in the processing. But because the background is so far in the distance the background stays very soft and all the flowers are super sharp.
I’ve been testing the Lumix GH5 and the Post Focus Mode in which the camera leverages a 6K Photo Mode wherein the camera creates a short video clip using all two-hundred and twenty-five focus points. Any one of these points can be pulled as an eighteen MegaPixel file. Or a range of images choosing a set of focus points. Or even better, it will combine all of the focus points into a fully focus stacked final image. This is an amazing technology to secure a look that is not possible in a regular capture with a camera. I love leveraging this tech to create artistic images.
This winter and spring have been wonderfully wet in the southwest leading to one of the most wonderful flower bloom seasons in many years. With that said I have been chasing some of those blooms, especially the cactus as they are absolutely beautiful.

Let’s take a look at some of the possibilities using my cactus flower friends.
This image has been processed using all the focus points processed in-camera from front to back. This is not necessarily a good look for this particular image as to the field of focus makes too much of the image in focus.
Another image using the same Post Focus capture but processed with a range of focus points which helped to isolate the subject of the flower buds from the background. The beauty is that this can be processed as many times using different sets of focus points for very different looks. All in the camera!
Here is another image with everything in sharp focus. Depending on the story you want to tell this can be a perfect rendition of the scene with all of the thorns in sharp focus. Very prickly.
This image has all the important information in focus with the background allowed to be more soft which has a different feel even though it was from the same video capture.
Post Focus is a handy mode to have in your toolkit. It makes it possible to create a hyper focus image with depth of field that rocks the house. Here’s an example I made when I was recording the Tech Talk Radio show with Mike Tabback at KAZM Radio in Sedona.
Here’s the Tech Talk Show which aired on May 10, 2017. We chat about the new technology in the Lumix GH5 including an almost endless focus available in using the Post Focus Mode. Find the demo capture and final image below.

First, here’s the video clip created with Six K Photo Mode. The recorded clip is less than two seconds. I have extended it to about six seconds in order you to see the camera making its way through the 225 focus points.
Above is the image fully merged using the in-camera settings of show host Mike Tabback.
Sharp front to back! And everywhere in between
Creates an almost image size of almost 5000 pixels.
There would have been no way to have the KAZM logo on the microphone in focus as well as Mike further into the scene no matter what f-stop was used in a single capture. When a lens gets stopped down to the smallest aperture diffraction and diffusion get introduced to the image which can hurt image quality.
Image was made with the Lumix GH5 camera with the 12-60mm f2.8-4.0 Leica DG Vario-Elmarit Lens

PS – If you have questions about using this technique or any ideas for future blog posts don’t hesitate to give me a shout. As a Lumix Luminary, I get the opportunity to work with a lot of the new technology including the GH5 Camera and some of the newer lenses that have been released.
