We need an automatic focus stacking feature like w/ pano.  This way we can have everything sharp in post.

Driving higher f/stop isn't viable as the ISO has to be raised or the shutter duration which is bad for obvious reasons.

We need it in a firmware update for all the drones that have an MF feature.  Preferrable 5 images or more for super sharpness.

edit: Post #21 has the originals and the stacked image. and look at Post #26

Why on earth would you want focus stacking when at the optimum apertures every single thing over about 6ft away is at infinity focus and sharpness?

It's not edge-to-edge, corner-to-corner sharp as it can be when you start stacking up, close to far images together in photoshop.  Load files into stack and align > Auto-blend layers after selecting the layers on the bottom right.  If you don't stack enough images such as the stack between far and close is too far with bokeh, you will have that blur be part of the images which is bad.  If you stack like crazy w/ say an f/1.8 500 times you can get and epic image which they do for macro.

An ideal should be at least 3, but preferably 5.  If we can go all the way to 10 it can be the best as if you set all the way to infinity or super close, you can still get blur.  When I did the test of 3 photos, I was fixated something all the way on the bottom right, middle, and upper right but not the sky then stacked them.  The all-around sharpness is like no other.  The only downside is the time it takes to do it.

You seem to have confused focus with sharpness, optical issues and circle of confusion.  They're not the same thing.
Focus stacking is not going to have any effect on that at all as on a standard drone flight *everything* is at infinity focus.

Stacking multiple images is a way of reducing noise or increasing apparent detail but its a totally different thing to focus stacking and ultimately you're limited by pixel size, optical qualities of the lens and CoC.

Nothing to do with focus stacking.  Everything is in focus.

You need focus stacking for macro because everything is very close to the lens, at quite a large focal length where the depth of field is tiny.  You cannot possibly get the whole scene in focus at once.
Thats nothing to do with a wide angle drone which has a small sensor and every subject is at infinity.

If anyone says stacking doesn't work clearly hasn't done test or test correctly.  It 100% works, at least when using Photoshop 2020.

The only thing you have to do after is crop out the lack of sharpness around the edges so the image requires up a 5% crop in, in all directions?  I can't stand the lack of edge-to-edge sharpness.  If you are using a Sigma 14mm f/1.8 at f/11 or f/13, you have 100% corner-to-corner sharpness with no lens distortion compensation in anyway and no distortion.  It cheats though as I think the focal length gets narrower a bit so I'm not sure if 14mm is retained.

I ran the tests but deleted.. nope you guys are in luck I have it including the originals. and look at Post #26

The file didn't work before for some reason.  I've updated it that it does work.

Just updated it 6:32pm 3/6/2020.  I didn't check my files to see if it's done right.  It's done right now I think lol.  At least it's corner-to-corner sharp, and that is what I want people to see.

You have to download the files and open them in MSPaint and zoom out to see the true sharpness.  Do like in this picture and hold left ctrl+mouse wheel down 2 times or just once to see the maximum quality.

You still don't understand what focus stacking is, does or what its used for.
Nothing you've posted is anything to do with focus stacking.
Edge to edge sharpness is nothing to do with focus.

Focus stacking a series of images where every single part is at infinity focus achieves nothing from a focus point of view.   

Again you;re using layer blending to achieve a different effect which is nothing to do with variable focus.

Hello AntDx316, you would need more than 5-images to do Focus stacking to really increase Depth of Field.  

To create a virtual image that appears to have been taken say using a lens set to f/22, when it was actually taken using numerous image with a lens set to f/1.2

Default fault focus-stacking on my camera is a 100 images.  Seen people use less, seen people use lot more.

When it comes to lens edge softness, aberrations, and distortions, really is a matter of Lens quality, and to some degree available correction filter for lens.  Some software programs like DXO Photolab, Lightroom, ON1 Raw have correction filters for professional lens, and popular semi-professional lens.

You can of course focus bracket a photo, using 3/4 etc focus points and then blend in PS , I’m not sure if this is what your talking about. With some handheld cameras you can set manually focus points and shoot a series of photos you can later blend onto one photo.
Is this what you are trying to convey ?

Other cameras can automate the process for you right?  Why not include that kind of one-touch automation on everything?

Yes my Fujix3 you can set to focus bracket manually or auto, in manual  you focus say at the point nearest you and shoot that point will be in focus and furthest point away will be soft, then focus to center point shoot etc etc, with auto you just set number of focus points you want camera to use and shoot, you then say you use 4 focus points and have 4 images of the same scene , you then need to blend these images in SW similar to PS.

Much of what your saying makes little sense to me like corner to corner .
I have seen some of Labroids work and it’s above excellent, if you want to know how to best get your images sharp then follow what he advice , you will find it pretty simple without complications, but do as he says not as you would think you would like him to say.
A few years ago he gave me very simple way to shoot panos telling me I would get better results than shooting auto, and he was right and I still shoot panos with this simple method .

I'm not going on word of mouth here.  I want to see some images presented.  You will not be able to match a good focus stacked blended image w/ a one shot on the DJI drones and if people's lives depended upon it then people should've listened to me.  It's just a waste of time going back and forth.  Show images, compare, move on.  This is one of the simplest things to clear.  If we get stuck here, we wouldn't be able to move on in the other advance areas.

I got into photography and videography because it can show us things that we would miss.  When you have tech working with you, that is reliable, works, and well-developed you can end up with changes that result in an awesome outcome.  When people film themselves on Youtube on how to control a motorcycle.  Well, I've copied it and didn't crash and I go really high-speed.  More than probably any of you would ever think about going.  Just replicate peak performance w/ evidence to back, figure out how it can work for us, and move on.  Every single time.  Not get stuck on methods that are considered obsolete.  It could suck as it feels sacred but it's either that or you get left behind, die, or worse in other areas of life.

I'm not stacking images when there are too many things on the move in frame.  I will just one shot and head to the next position.

Again it’s very difficult because you’re either talking rubbish or it’s been lost in translation, nobody mentioned anything about a single image which incidentally your wrong about, what happens is your questions are a bit daft and you won’t listen to correct advice .

The edges are blurry on the long end.  It's just masked by the object textures at the corners.  If you take pictures of homes, and vehicles that are in the corners they will not be sharp.

To actually get corner-to-corner sharpness in the photography world is the difference between a $300 lens and a $2k lens.  I'm just trying to share a workaround for automation that produces pretty much the same results.

Focus stacked? Cropping the sides out that are blurry doesn't count.  I'm saying RAW off the camera sharp corner-to-corner. I mean, you will still have to crop but not as massively.

Believe those claiming they get sharp pictures from their Mavic Pro or Mavic 2 drones, need to do a side by side comparison between their drone and comparable MegaPixel DSLR (or mirrorless) camera which has quality glass lens.  There is sharp, and there is Sharp.
Mavic drone images tend to be soft (aka not sharp).  Which is to be expected being good part of cost goes towards quad-copter platform, R.C., batteries, and charger.

Which leads me to wonder if Focus Stacking would do much good.  Being Mavic drone images are soft regardless of whether focused up close, mid-range, or near infinity.   Focus Stacking 5 soft images taken at different focus points, is going to result in virtual image that is overall soft from foreground to background.

Well here’s the images with Mavic and M2, soft they’re not, but maybe those who think That DSLR in same price bracket can take sharper or better images then maybe they should post them, I can’t find any camera costing 1k that can do any better than what I see in above photos, it’s all very well comparing these with cameras that use lens costing 2/5 k but that would be ridiculous, compare apples with apples, those pictures in link above will compare to any camera costing 1k, but remember cameras take files photographers take pictures. I seen plenty of Sh#t photographs taken with gear costing a leg and an arm and plenty of great images taken with Mavic air.
Also something to remember, drone photography is very much in demand at the moment, and people are always happy to buy good drone photography.
And just so as you know, it’s now vogue to have some softness in photos, pin sharp is not so popular now using Gaussian blurs to soften photos is a much used tool in PS nowadays.

If your camera cannot take pictures like above then there is most likely something wrong with the photographer, but we’re all here to learn and improve.

There is no such thing as corner-to-corner sharpness from a one shot with any DJI drone.  Even all the way to the max f/stop, in MF w/ DJI RE Goggles on, moving from closest for infinity will show some DOF.  Unless you are running f/13 or higher on an expensive lens, you will Not get corner-to-corner sharpness.  You will have blur somewhere and some of the spectacular one shot photos from drone aerials are done where that blurry area blends in w/ the texture of the environment.  There is no need to argue.  This is how it is.  You can get away with a pano shot then cropping in, cropping in, and/or blending focus stacked images together.

5-AEB with pano is great of course but not with an ultra-wide lens.  The distortion is crazy.
