We all know what a 4K image looks like. With its resolution of 3840 x 2160, it works out to be an 8.3-megapixel image. Double the number of pixels horizontally, and you get 8K resolution at 7680 x 4320, which is about 33.2 MP. Do it again, and you get 16K resolution at 15360 x 8640, or roughly 133 MP. Sounds incredible, but have you ever wondered what a 32K image would look like at a whopping 531 megapixels? Well, now is your chance!
While conducting my November Death Valley Workshop last year, I decided to use the new Nikon Z 85mm f/1.8 S mounted on the Z7 to do a multi-row panorama at sunrise. Knowing that the Z 85mm f/1.8 S reaches its peak performance at f/4, I captured a sequence of images at this aperture in several rows, as quickly as possible using the standard panorama technique. Since everything was at infinity, I did not have to worry about parallax errors.
The result of the stitch in Lightroom was an image with an insane amount of detail at close to 500 MP resolution. Sadly, it was not enough to make a real 32K image at that resolution, because I did not have enough vertical pixels for a proper 16:9 aspect ratio. At 30720 x 17280, or 531 MP, a 32K is no joke!
After I cropped the image to 16:9, I ended up with roughly a 300 MP image. At this point, the only way to get to 32K was to use an upsampling algorithm that can increase the image dimensions. I opened up the stitched panorama in Photoshop, and used the “Preserve Details 2.0” resampling method to get to 30720 x 17280.
The result was a massive 4 GB TIFF file that I now had to export as a JPEG image to be able to share with our audience. The first image worked out at around 200 MB, but it was still too big and impractical. I set JPEG compression to a lower value, then tried again, and this time I got an image just shy of 100 MB. Here it is:
The above image is a sample preview. In order to get the image at 32K resolution, you will need to download it to your computer using the link below, then view it with an image viewing app. MacOS users can utilize the Preview app, although it will take some time for Preview to fully render it (make sure you wait for a little after opening).

I do realize that I could have gotten a 32K image out of my equipment without needing to upscale it in software, had I used a longer lens and more rows of images. However, that was the equipment I had in my hands, so I had to work with it. Also, something like the Fuji GFX 100 would have worked much better for the job.
Still, the point of all this was to show what type of detail we can expect from a 32K image. Imagine a 32K-capable camera that can capture such detail with a single shot in the future. That would be insane, although I am not sure such a camera would ever be practical…

Hi Nasim,
I love such stitched, detailed photos. I took one myself a good year ago from Zermatt with the Nikon D850 and the 300mm f/4 with the 1.4xTC, so f=420 mm. The resulting image is just abobe 470 Mpixel and shows the Matterhorn as seen from my hotel balcony in Zermatt. Zooming in, one can see the Solvay hut up on the Hörnli ridge and even individual climbers on the way to the summit. If you are interested, I can send it to you via a WeTransfer link. The jpg file is 297 MByte.
Cheers,
Geir
Geir, would love to see it – sounds like a fun pano to check out!
Hi Nasim,
Found your reply just now. Here is a link to a jpeg version of the photo.

On the Hörnli ridge (the normal route to the summit from the Swiss side), one can see the little brown Solvay hut, and looking a bit closer one can see people on the way to the summit.
Cheers,
Geir
Very impressive, Nasim! Thank’s
Glad you enjoyed it Pino!
Antonioni’s film “Zabriskie Point” is a 60s counterculture classic, with some nice airplane footage, a desert cliff mansion and unforgettable ending.
I remember that ending with the explosion!
I’ve also found preserve details 2.0 to do a great job, although I don’t like the default settings, in particular I set noise reduction back down to 1, or I thought it was creating small artifacts. I’m curious as to what settings you like best.
RJ, I don’t remember exactly which NR setting I used, but I went back and forth on the slider and looked at all the corner and noise areas to make sure that it looks good before I clicked the OK button.
How about using superresolution or pixel shift technique to make such a project more easily? obviously not straightforward, but almost certainly feasible.
Maciek, I am really hopeful that Nikon comes up with a firmware update to do this!
Nice job with that ISO 64 ;)
Alvaro, that’s the way to go with the D810, D850 and Z7…amazing sensors!
Cool image Nasim! If you want that much resolution — real life resolution, not stitched or interpolated — in a single image, LF is the way to go. Want mind-blowing Gigapixel resolution? Then try 8×10. You won’t be disappointed, and you’ll never go back! :)
Pierce,
Indeed, digital can produce a sharp image. But it takes a lot of effort for that Resolution or even sharpness front to back.
For this and other reasons I still use 4×5 and I’ll never go back.
Pierce, I would love to do it, but that’s when I do a personal trip. Can’t really be playing with a LF camera while teaching a workshop :) The image above took me almost no time to execute, all while I was teaching to a group of 11 photographers.
Amazing. I cropped to 1/8 on the long-edge .. which should make it 4K and it looks really sharp on my 5K display. That’s a crazy amount of digital zoom capability .. among other things.
Thank you Talha! If you know your actual screen resolution, you should resize it to those dimensions – it will look much better that way, and no pixels will need to be stretched.
I moved up to a Xeon processor and 96gb of RAM for this very reason.
I’ve shot the exact same pano, but with a D810 and 55/2.8 Micro Nikkor AIS for evenness of illumination.
I use ON1 for upscaling, rather than CS6EE.
Your test review of this sometime back, convinced me that ON1 is better at this.
Remember good old Mr. Gates: we will never need more than 640k.
Too big for now, but I won’t be surprise this is going to be standard resolution in a near future.
Sorry bgavin. It wasnt supposed to be a reply to your post… Nasim, anyway I can move my post?
Simon, yes, I remember him saying that :)
No worries about the post replies, sometimes it happens!
Bgavin, yes, there are better tools out there than Photoshop, but at the time of doing this, I didn’t have enough time, so I just did a quick job in Photoshop :)
Really nice image with amazing detail. The algoritms for upscaling are getting better and better.
Thank you Anders, glad you enjoyed it!
