Very nice but if you see the focus on the single photo is in a different place! So this is not apples to apples comparison! And no doubt the pixelshift destroys the single photo! But pls next time focus manually on the same spot exactly!
I am very grateful for your analytical tests because they easily present the information and relationships that interest me. With my Sony a6300 I tried photostacking in Affinity and was 60 % happy with the results. The a6300 has a manual focusing aid of up to 11.7 times. The a7rIV could probably have a 30-fold focus aid, I expected that you would set the focus once in manual mode and use it for all 16 pixel shift shots. I ask you and all a7rIV owners, who are mentally and practically dealing with your test, whether the AF of the camera caused 16 minimum focus differences, so that the software not only calculated a two-dimensional increase in resolution due to pixel shifts, but also an additional three-dimensional sharpness expansion through focusstacking. If so, your trust in the AF would have led to an expanded depth of field. Could you kindly extend your test with manual focus? Object a round can or bottle with very small writing for simultaneous two and three-dimensional sharpness gain with 16 mult pixelshifting.
Although I don't have this camera I have used pixel shifting before and I found that the best results were achieved when using manual focus. Autofocus can reset prior to each exposure. Some people commenting on focus stacking, why would anyone want to use focus stacking with an image of such a huge size? There should be no reason to go in so close.
Hi 🙋🏻♂️ ich habe das gleiche auch gemacht jedoch bleibt die auflösung anzeige immer bei 5304x7952 pixel🤷♂️ obwohl ich 4 bilder zusammen setze gleich wie in deinem video.. Hast du einen tipp oder wieso ich das bicht sehe das es dann 4 mal grösser sein sollte als 42mp total (a7r iii) Danke🙂
Hi Cem, das klingt merkwürdig, sollte eigentlich problemlos klappen. Hast Du alles exakt gemacht wie im Video? Kannst Du Deinen Workflow mit einem Video auf YT hochladen? Ich schaue mir das gerne mal an.
Tony & Chelsea claims - after testing - that pixel shift on Sony a7riv never worked with him!! He tried that and in every time he achieved 0% succes. Does it work with you??
Yes it worked. But if I compare the Multishot on my Sony A7RIV and the new Multishot feature on my Leica SL2, the SL2 always delivers if the scene is still (so no artefacts or "mistakes") whereas the Sony sometimes produces artefacts in the composed image which should not be there. I guess that's what you are referring too when mentioning the Northrup's experience with Sony Multishot.
@@mathphotographer Great. I downloaded several files and noticed that some of them have a mesh like noise or precisely; uniformity, in other words, they are as if they were superposed but not alligned perfectly!
@@sokals44 Its not the duration of the flash that is an issue - that is as you rightly point out very fast - for instance even my Broncolor in HS and High Speed mode would not be able to keep up with the sensor creating upto 16 images in just a few seconds - so natural light and possibly a continuous light source - but one which strobes such as LED or fluorescent will not work. I use my H^d400c on location sometimes and I have tried it but it is really a fiddle and most of our clients don't need that sort of resolution - when I used to make 5x4 repro transparencies of artworks years ago this would have been a lifesaver - so I see the application for it but its a gimmick that most people will only use down the pub when talking about megapixels. My car an ordinary Golf has radar guided cruise control but in the real world it leaves enough of a gap between you and the car for a flashy BMW driver to sneak in- so the my vehicle moves back and then I get flashed from behind and the cycle repeats so I don't use it
sokals44 flash should be constant if it is a high quality set to manual. The settings allow you set a time interval between exposures that should be long enough for the flash to fully recycle.
@@Marcos-ee7nt ok, so let me get this. You're saying the guy messed up the test, because on the multishot photo, he messed up the focus. Assuming this is true, that would mean the multishot photo would have much lower resolution than it ought to have. Regardless, the multishot photo had significantly higher resolution than the single photo. How is that not impressive? I can come to one of three conclusions: 1. You're blind as a bat 2. Your monitor needs adjusting 3. You're trolling
@@robiulahmed What I mean by mess up the focus is that he didn't focus on the same place in both of the test shots, the multishot looks clearly sharper because it's focused differently in favor of that little spot he choose to compare

exactly! it’s a shame... we couldn’t see how much more real detail was on multishoot 😢
Amazing details!
How about trying "focus stacking" for landscape, using pixel shift next time? 😁 ..it would be a hell of a job!
Good idea, thanks and will try to find time for it.
totally works and with HDR too - megafiles but intoxicating detail to give Hass HY6 a good run - which we also use
Why? Focus Stacking for landscapes would not be necessary.
Pixel shift will automatically turn on electronic shutter.

focus was shifted in single and multishoot 😑
Focus was not consistent. Pointless comparison.
Excellent tutorial. Exactly what I was looking for - the whole process from start to finish.... thanks a million!
This is wonderful!
Thank U man
Skip to 4:02 for tutorial.
Does the Sony A IV have the ability to do in camera double exposures and in camera Panoramic? Thank You !
thankyou GBU

Can you post a link to download the sony viewer program? Ty
Has anyone ever actually gotten this to work? No luck here.
thank you very much everything is clear and short
can you use stroibes witj this feature? thanks
Thank you sir, appreciated.
Bravissimo e chiarissimo, grazie era proprio quello che cercavo!!!
Camilla & I are going to have to get one next year for our wildlife photography
How do you get the file size to show in the display? It doesn't display on my A7R4.
Which part of the video are referring to? Mins/Sec?

Thanks George. I will likely make a similar video for the new Sony A7R V where pixel shift multishot works even better.

Does the Pixel Shift Multi Shooting function work with flash units?
For the a7riii, yes, but it's only 4 shot. Don't know about the 16 shot mode here.
@@robiulahmed Yep it is designed exactly for this
Not as good as Pentax PIxel Shift
Have you tried them both side by side?
@@melb5996 regarding file size and simplicity... i saw so many review about them.
Does the Pixel Shift Multi Shooting function work with flash units?
Yes it is designed 100% primarily for this purpose - but locked off
@@nelsonclub7722 But flash light isn't constant. Is that not a problem?

thx!
very impressive!

1:24 Why is this model being called "Mark 4"? Like almost every reviewer says it but I can't see it anywhere in Sony's paperwork.
This is the first time I've seen a proper side by side demo done so well. Amazing work!
Not really, he messed up the focus on the multishot one, he should've used manual focus from the begining
@@Marcos-ee7nt Well, that makes it even more impressive, then. Look at the resolution difference, it's insane!

Can you use the same stacking software with 16 images shot with a 26 mrgapixel camera a6600? Please say yes
