I just got a Z8 and can’t wait to create archival quality images of my wife’s paintings 😊
Perfect use case. 😀😀😀🖼️🎨
Damn, these days your videos look more like a scene from a high end cinema ❤🔥
Can't wait for it to hit the Z9 so I can try it out for Astro!
I recently stumbled across a load of old family photographs, dating between circa 1880 to 1920. Shot in various photography studios, these are small pics, measuring just 2 X 3 inches, some even smaller. As might be expected they are not in the best physical condition, some badly faded, others with surface dirt ingrained on the surfaces over the years, not to mention the occasional tears. but it's fascinating for me to see pics of my great, great grandparents and my first instinct was to restore them.
The timing of the find coincided perfectly with the new Z8 pixel shift update, so I set about copying them using the 32 frame 180MP option. The clarity of the reproduction has been very impressive. Using Photoshop to enhance the detail, I now have files I can print significantly larger and still have them looking good.
Did the pixel shift actually help with the results? I like to think so. Whilst most of the original images have an element of slight blur in them, a couple of them are remarkably sharp, but badly faded. Here is where I think the pixel shift has come into it's own, these pics just burst back into life, with detail far exceeding my expectations of them.
Landscape? Maybe. Architecture and product photography? Probably works out well.
The best use-case? Shooting digital copies of negatives or positives.
Scanners would allow for multipass and hence would register red, green, and blue values with each coordinate in the subject. Plain Bayer shooting only has one colour per photosite and the two missing ones must be guessed in raw processing.
A Z f or now Z 8 with FW version 2 will do that convenient variant of multipass for you.
This is not about "sharpness" or more pixels in the resulting image, but about removing uncertainty about missing colours and about colour space and contrast envelope.
The "noise" everybody talks about is bluntly put "Bayer noise". It is implied in the paradigm.
Things like colour noise and luminance noise are just Bayer noise. And when we see it in our photos then the deBayerisation (raw conversion) has not properly worked out. The software was too bad, had dumb AI, etc. In most photography this has nothing to do with "not enough photons".
As to Nikon's writers using photographic jargon ... they appropriately introduced the term focus-shift shooting for the in-camera thing that needs focus stacking to be done in post.
Pixel-shift .. meh.
To appreciate it, we must understand the Bayer paradigm first. Then we know Bayer's problems. So we would be motivated to use it when it improves results.
And we should call it "photosite shift" because the photocells (photodiodes, with their individual circuitry called photosite) in the sensor are not "picture elements" and these photosites cannot register RGB. And RGB we would expect in "pixels".
Hello from Germany 😎
It is interesting how good the Fotos with pixelshift got.
As you pointed out, movements in the foto or by the camera are getting an issue. You need a stabile tripod, best not much wind, etc.
With each of your recent videos, I am more and more impressed with my Zf.
Thanks Ash!💪🏽👍🏾
Definitely more on the pixelshift please. I'm thinking about cropping into an image that's 180 Mb and the sort of end result you'd have. The Z8 is on the way so this is something I'll be right into.
Can't wait to try this feature out. Even the 4 or 8 shot options look like they could have big IQ improvements for times when 180 MP's aren't really needed. Thanks as always Matt!!
There will be many uses for these high end files of static scenes, product photography, architectural, some landscapes/cityscapes and much more. I've just tried it and the files are, yes, amazing. Thanks for explaining the process Matt. 😊
Superb Matt. As expected.
I, too, would love to see an astro demo with pixel shift
It seems you should be able to handle some movement of in-focus subjects by masking the area around the subject and replace it with the corresponding area in *one* of the 32 images. You will lose the denoise effect caused by averaging the images, and the resolution will be half that of the rest of the picture, but I don’t think that would be noticeable if we are talking about a small part of the image. It may be doable without any new post-processing tools.
I’m looking forward to playing with pixel shift. Time to whip out the tripod again. Thanks for the very instructional video Matt. 👍🏻
Extremely interesting - looks to be an essential and magnificent tool for certain situations, not all. Especially for low light situations and high res/large printing. It is back to tripod days, so careful choice of pixel shift use is paramount. Great to experiment with too - it doesn't work for moon shots (the moon just isn't still !). Thank you for exploring Matt - look forward to more !
Yes please....let's have more of these articles about Pixel Shift.
Also......please.....when is the Nikon Z9 going to have this? Surely it will?
Great video ..as always. Thank you.
Amazing technology - for my next body upgrade. I continue to be amazed at the city you live in. The nightscape is incredible!
Keen to play with this as a property/architectural photographer. Would love to see the colour and dynamic range differences.
Hi Matt, great insights into pixel shift, thank you! I'm holding out with my Z7 II until Nikon will present the Z7 III, then I will have to see wether my path will lead me to the Z8 oder Z/ III ;)
I want to see what this can do for astrophotography. Definitely need a motorized equatorial mount for the long exposures. So, for stars, nebulae, anything extra solar system, it would be easy. For the sun and the moon (or planets if using a telescope), I wonder how that would turn out. They move, but the exposure times could be very fast as they emit a lot of light. So, each shot would be in focus, but the next shot would be moved slightly. I wonder if each image could be lined up in post as it moves across the sky.
Being 80, it'll take me a while to learn all this stuff Matt - but I love the process, and that was a great introduction. I think I need to make some written notes, though, so I don't get lost. It's a shame it can't run faster & leave some the moving objects in frame - an image with nothing moving is maybe a bit sterile. I think I beat you off the starting blocks with "night" - I started plunging into it with a Zeiss Contaflex somewhere around December 1963, shot a whole roll of film at an office Christmas party - and of course everyone completely ignored me, didn't believe for a second that any of the shots would come out. So they kept behaving badly, as people so often do when they're getting plastered. Next month I brought the prints in. Word got round, apparently - I locked the film and the prints in my filing cabinet, went out for an hour, and when I returned, found someone had broken into my filing cabinet - jemmied it open, by the look of the mess they made of it - and the film and prints had disappeared! Later on, in 1966, I took a shot of a double-header steam loco train pulling into Flinders St station around 11pm. I erected my tripod, with a Contarex on top, and blasted away with a Graphlex flash - used three bulbs! Got sprung by the VicRail police, kicked off the premises, banned from travelling on VicRail for 3 months - and caught the "Overland" home to Adelaide, from Spencer St station, the following evening!
Thanks for another great video Matt........Olympus had this out in their OMD-EM1 Mk2 cameras ages ago. It really is fabulous. I love the way Nikon have set the shift for 4, 8, 16 and 32 images.....so much better. I'm looking forward to more on Pixel Shift. 😁
Matt, please, you videos are incredibly helpful but just flat incredible. What are you shooting your moving stuff with? It is so clean it makes me want to cry! Thanks Matt and keep up the great work! Stay well.
GREAT Haircut Matt, really nice! • YES, more on Pixel Shift, please.
Matt, move to something in excess of 60sec exposures and see what happens! it is amazing how the system seems to get rid of individuals/movement through the frame. Water and sky also lose the issues of the pixels. I have not tested this much... but the theory is there!
It introduces rgb artifacts
Pixel shift really seems to be best for landscapes and skyline photography. If the photos are composites of a number of shots then how would moving objects be properly rendered?
That is a beautiful city with the boats along the waterfront. Not very crowded either! Melbourne? Wish I could afford new camera gear! Thanks for showing us some results of pixel shifting Matt!
Impressive, even for you! Thanks so very much!
Thank you, Matt. Going to give this a try over the weekend. Hoping they'll add it to the Z9 as well.
Thank you Matt! I’m going to have experiment with pixel shift on my ZF.
Nice post, I'm waiting for the next Z9 update to include Pixel Shift. It's going to be an interesting process here in Barcelona, too many people. As you know way more than me about printing, how large could you print one of these images for an exhibition?
Have you tried filters and long exposure to get rid of the people?
@@TonyHedges yep, do that frequently. An example alford.photo/galleries/monochrome/#pid=CityOfShadowsStyle.jpg. where I used a really dark ND, and a long exposure, but it's so sunny here its difficult :)
Fascinating technology, I wonder if they could bring it to Z6ii, we have never had a 2.0 firmware update.
Nice job Ash!!! Matt this is fabulous, and suddenly an updated Z50 that would be my ideal hiking camera COULD be my ideal hiking camera by allowing big megapixel landscape shots when needed and otherwise being ultra-compact and ultra-light. Nikon - please bring in-camera charging and pixel shift to the updated Z50.
Beautiful Video !!! :) :) :)
Pixelshift is a great way to enhance resolution for static objects. I have been using it on several occasion with the A1. Btw, I like your night shots of Melbourne.
Thanks for this video, Matt, very useful! I wonder whether we can mitigate the moving subjects or water with longer exposure.🤔
Have just tested PixelShift on my Z8 with Z105MC. This effectively turns the 105MC into a 2x macro lens!
Excellent video thank you.
You are welcome David !!!
More videos/examples of pushing the capabilities of pixel shift please!
Great video, thanks! Plus 4 ev and no noise is so handy...It’s funny how 4 times the resolution wasn’t obvious to me, but I guess TH-cam compression smudges everything.
The lowlight AF is mind blowing good. If you process the files right you don’t even need any AI noise removal all the way up to 64,000.
I have one in blue to complement my Z 9 and there are certainly times where the Z f is better than the Z 9.
That is very informative. Thanks! Current Nikon version seems to work best on static scenes. It would be great for enlarged images such as posters. AI in camera is the next step of implementation.
very informative
This is a awesome program! I have a Zf and they still will be large images. The noise reduction is fantastic. The image with the Vespa and the people in the background on my screen they looked perfectly clear. But even with the. movement it is a fantastic image. I need to try it out on the night sky. If we can get some calm nights. And temps a bit above the negative side of the thermometer. I think you should do a deeper dive into it. Have a great weekend Matt. And you should have mail.
About noise … you can reduce noise substantially by taking several shots of a static subject, say 5 or 6, and, in post, stacking them. At least in Affinity Photo, you can choose the averaging function, so that each pixel in the result is the average of the pixels in the stack. For a ‘real’ pixel, the average will be the same as the corresponding pixel in each of the shots. If there is a noisy pixel, the noise probably won’t be in the other pixels in the stack - since noise is random - so the contribution of noise to the averaged pixel will be about 1/N of what it is in the noisy pixel, where N is the number of shots in the stack. This is what happens in the pixel shifting algorithm in the cases where you select for noise reduction as well as higher resolution, but you can do this with any digital camera.
4 stops boost? Holy jeepers.
I think we now need to try PIxel Shift with some Panos, and focus stacks. Might have to give that a go soon with mine and see. Would be a long process but what would we get
I would try the pixel shift at F8 or F11 and see the extra sharp detail compared to F2.8. You likely need to raise the ISO a bit if needed for a 2 second pixel shift shoot.
Jaw-dropping... The only question I have is how camera handles lens distortion. Let's say I want to take a night sky shot on a very wide lens - thoughts?
What I would like is a nearby city as cool as yours to shoot. What camera was strapped to your head when you were riding around at night?
Great test Matt. I'd like to see a 32 image test shot with a faster shutter speed and higher ISO, say ISO 6400 and adjust shutter accordingly. That would be a great way of showing the noise reduction whilst getting the shots fired off quickly🖕 PS I hope Nikon don't leave us Z9 shooters out in the cold!
Stitch a panorama together with pixel shift then you can 2, 3, 4, 5, 6. Just keep stitching till your landscape has so much detail you couldn't tell the real from the photo. Then, only back off when your computer begins to swear at you and go on strike.
Thanks. I did try this on my Z8 without worrying about the subject. Wanted to see the process and it's fine. Now I have to figure what's worthwhile for me to actually shoot with this. And do I really need that huge file. guess it's time to experiment. have or will you do this with more mundane stuff? Thanks - Tim Oh, as always your nighttime cityscape stuff is just gorgeous !
Could be very good if you know that you are going to do a heavy crop. So in theory it could give you a perceived longer lens.
Btw, in C1Pro you have to double your sharpening from default setting of 180 to match your 180mpx file to the regular 45mpx file.
Looks very worthwhile! Not only what you've shown but I am curious. Just how clean is the photo if the 180MP file is downsized to 45MP? I imagine that noise is a thing of the past. Maybe.
32 exposures is kind of like 5 stops of latitude. Ie if you take the sum of the exposures instead of the average (which is what the algorithm allows) you get five stops or 32x the light.
I’ve been playing with the pixel shift feature on my Z8 as well. I have been experimenting with items in the picture that aren’t important to the final image, but become a distraction because they moved and the final image is blurred in that area. (Think about the flags in that first image you took or the people in the restaurant in the last one). You have 32 raw images to choose from, so once you have created the merged pixel shift image, make a manual stack of the merged image and one of the original files and simply “cut out” the area of the merged image revealing the original raw file below and you now have no movement. Make your final edits…
Very good plan. And I think worth making a video about. My guess is that is what Sony ‘AI’ does. 😀
@@MattIrwinPhotography I’ll be watching for that video! Sony may very well be doing that. Like you said, it would be wonderful to know what the software is doing behind the scenes to create these pixel shift images.
Very interesting Matt, as a Z9 birder I am looking at the tech and wondering how it would affect me. I think I would be waiting for a Z9ii, but imagine this with a global shutter? 32 shots could be taken almost within a second. Eliminate noise, that is huge. Global shutter probably means the end of noise in photos! I am but a flat pebble skimming across the surface of a very deep lake though, making these comments, because there is much more to what I am saying, or rather outlining. How would ISO be in a global shutter/pixel shift world? Would we be more mindful of dynamic range and relegate ISO to an after-thought? I can see another long Matt-Irwin-opines-on-imponderables type video... All the best Matt
It's already implemented in the A9III.
@@renestaempfli1071 yes but they’ve kinda f’ed it up. What good is global shutter if you are sitting about waiting for the buffer to clear?
Do you have anA9III? On my A9III it's almost instant.
Question, do you turn off in body stabilization when doing pixel shift images also because your on a tripod? Thx for sharing all of your thoughts, reviews, and imagery. I have the ZF and Z8 and this looks like fun to give a try.
I have the ZF but haven’t tried the pixel shift yet . I loved your video on the z8 version and looking to see the ZF version . Could you also do a test with the different versions of pixel shit 4,8,16,32 and compare the images please and is there enough difference to go all the way to 32 . Is it also possible to do a photo with only 4 samples of pixel shift with a fast shutter speed , say 8000s hand held . Love your videos keep them coming .
Do you think pixel shift would be useful for astro photography when using a tracker mount?
What’s your thought about an 8 sec Astro Milky Way shot should be short enough to avoid star trail movement and a game changer for noise 🤷♂️
Great explanation Matt. My question is: Is pixel shift something that requires the sharpest glass or can one use older lens that have some character and get good results?
Do you want a lot of sharp pixels or a lot of blurry pixels? no free lunches
ASTRO!!!!
Excellent and helpful demo of this cool feature! I'm going to see how this works with some motion blur. Example - landscape with a moving river in the scene, 1/2 second shutter to blur water.
Also I've heard that Adobe Lr / Ps / Camera Raw will soon be able to merge Nikon's Pixel Shift files, so we can pull NX Studio out of our workflow (although that software works great too).
Do you think nx will one day update to remove the RGB artifacts from subject movement
I am curious how a MilkyWay shot will turn out, since you leave the shutter open 6 to 8 seconds anyway.
Pixel Shift technology is helpful, however a Nikon medium format camera would do better. However, this is only wishful thinking, since Nikon must first complete the Z lens lineup.
With regards to Noise Reduction (only) - taking several shots and computing them to reduce noise is nothing new. In astro photography this is a standard workflow. You don't need the Pixel-Shift Mode in the camera to achieve this.
Is the ghosting lessened with a longer gap between images?
After creating a large megapixel pixel shift photo do you thing it has any advantage if it is downsampled to a smaller MP? I experimented with a 32 shot PS shot of my motorcycle where you could see every dead bug on it. I down sampled it to post on social media and even with the smaller MP size I still think it made a difference. Thoughts?
Question! I was wondering is it possible to combine Pixel Shift with Focus Shift? That would he next level
Hi, I’m shooting with Fujifilm gfx100s but it’s not good for all types of photography which I like (Portrait, Landscape, Still-life). It’s heavy and bulky with gf lenses to carry around, and slow for sports and wildlife if sometimes I like to experience it! But it seems Z8 is all in one camera. The only matter important to me is if I switch to Z8, with 14bit and 45mp, could I achieve the same high images quality (detailing, colour rendering, and deep dynamic range) by gfx100s with 16bit and 102mp? Thank you.
This is brilliant for product advertising, but probably limited use for wknd shooters. Z7ll is small it's my love it, if there is a Z7lll maybe a worthy upgrade for pixel shift. The 8 is just too expensive for most of us.
Also works on Zf giving 96mp.
What camera is being used for the Hyperlaps Especially the Night laps?
DJI pocket 3 😀 love it.
How does pixel shift work with shooting tethered? I'm an art and heritage reproduction photographer, and curently shoot tethered with capture one and a D850. I've been hoping that a professional implementation of pixel shift would become available for the Z8. This seems to be the case - you have at least confirmed that a proper raw file is produced.
Hmm, what happens when you need to reduce your file size because the place you want to upload to rejects your image. How much resolution will you lose and would that negate using the pixel-shift?
The Z7 doesn’t have the sensor for this I take it ?
yes, amazing but after pulling the specific image files into nx and creating the nefx file how do you migrate this file into capture one And what version of capture one is needed. I some times see nx studio prevents me from moving a file to PS stating the file is locked. what say you.
Latest version of Capture One to read the NEFX, 25.6.0 version of Photoshop opened the NEFX also :) Let me know how you go. cheers Matt
How does it deal with Hot/Stuck Pixels? I wonder cause my Z9 has about 30 of them
Nowadays there is no good film scanners in production, unfortunatly, - so Pixel-Shift is the only option for high-rez digitazing Medium Format film.
Will the camera create/merge the image after the 32 shots immediately or do you have to merge these 32 photos using software such as Lightroom?
You use Nikon NX Studio to do the merge, thereafter you can edit the file in Lr etc as you like
He explained that
He did indeed
@@markturriff994 When will Nikon support Linux users?
Keeping 32 originals + the merged file is gonna be pushing 2Gb per capture even before Photoshop gets involved. Need. More. Disk. Space.
How is this different from bracketing
Bracketing changes the exposure - pixel shift keeps the same exposure but moves the sensor slightly for each shot.
Will pixel shift come to the Z9?
It will eventually
This may be a shortsighted take and a minor point of an excellent video, but I dislike the idea of AI processing to automagically remove people, movement, etc. I know 'traditional' editing is already messing with the "reality" of a photograph, but to me that just _changes_ what is already there. AI conjures up things and removes the image from the world into fantasy.
Again, probably shortsighted and grumpy, but I sort of like the idea of reality's limits _exposing_ creativity rather than seeing them as _imposing_ on an idealised picture if only those people weren't in it or the wind weren't rustling the leaves.
I guess with a longer shutter speed and a delayed pixel shift you lose the rest of the people completely. would love to test it, but unfortunately I "only" bought the Z9...
I would think your voice would vibrate the camera.
If you can shoot 32 pictures in 1 sec then animals will look good even in super dim conditions.
