How to force S20 Ultra to use 4x telephoto camera at 4x zoom? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi all,
Hopefully with the S20 Ultra out for this long that you all have had a good play with the camera. One of the issues that I've noticed is the situation in which the camera will use the main camera and do a digital crop even at 4x. It keeps cropping until it reaches 10x, where it switches to the 4x telephoto camera.
There doesn't seem to be a single trigger for this to happen. I have found that sometimes it will do this even in outdoors bright light. And then other times, it will use the 4x camera at 4x zoom indoors in a dimmer situation. Then there is also the focus distance situation where the 4x camera has a close focus distance of about 43cm but the phone will still select the main camera instead of the 4x even when you are further than 43cm away.
I really wish Samsung would add a setting in the camera app where this behaviour can be switched off so that it uses the 4x camera at any zoom setting from 4x and above instead of the random situation that we have now.

P10 Camera Talk Thread

anyone have success in running google pixels camera on P10 for HDR +, and what other camera apps You use ?
I use Cortex camera for quality slow photography (multi processing) like S8 but much more frames (s8 takes 3 photos and combine them) Cortex use 10 - 100 photos for best quality.
I also use A better camera, but still missing Super sensor option on P10 for best output.
Stock camera use too much sharpening for landscapes and distance objects, but it is fine for near objects...
I've not had any problems with the stock camera and can't get Google pixel camera to install.

Anyone having problems with the panorama photos they are crap! The joins are rubbish and any horizon shots I take look like the Manhattan skyline!

Looks mostly fine to me when shooting horizontal panoramas. The only vertical panorama I've shot is blurry on one half and I don't like manual switching between shooting vertical and horizontal panoramas. Overall I like samsung's panorama user experience better but I think I'll live

Yes but stack bw & color photo? result is fine details but also some noise is present.
The P10 raw image have very high dynamic range. So it can stack them like the Pixel does.

Yes they are ... Huawei have to improve ?
The panorama is really not good. I hope Huawei will fix it soon.
For now, I have a photo for you all I made with my P10. Nothing edited, shot in manual mode free handed.

RE: P10 Camera a talk
I'm seeing much better results than Pixel or iPhone 7.
Quiet satisfied with the camera but I hope they will port PanoSphere to their Camera Mode
This is one shot with a really hard light, the phone however did a really great job.

Just casually run into this thread (I own a Mi5s) since I have also looked for alternatives to Google's multiframe hdr+.
On the Mi5s Cortex works wonderfully on low light still subjects. But my favorite app is Snap Hdr Camera on multiframe Nightmode (usually set to 4-8 frames) for those shots that require iso 400-2000, much faster than Cortex, and better than Better Camera on my phone. Incidentally Almalence, Better Camera's developper has licensed its technology to Huawei in the past.
Is there a way to completely disable all the beautification and bokeh options for the front camera? I don't like the effect at all and disabling it every time can't be the only solution.
That's weird. On my phone, it's only on if i left it on the last time I used the camera..

Unable to select tele-lens on LG G8s

Greetings Just got my hand on a LG G8S here in Norway and I'm pretty happy so far. I started exploring the (three) cameras and noticed today, that if I covered the tele-lens, it did not make any difference. Activating the zoom mode (big tree icon) still provided an image, showing that it was just using a digital zoom on the main lens. Wide lens works fine however.
I also noticed, in manual mode, I could not activate the tele mode at all. Seeing also that the aparture did not match the tele one witch should be f/2.4.
Could it be that I have a G8 firmware, which only supports two cameras?
Thanks!
Pål
Try This.
Guess this scenario is been discussed and tested on other LG triple camera phones with Telephoto lens.
G8s telephoto lens with F2.6 needs good light to work, in poor lighting it switches back to the main/standard lens and offer digital Zoom.
Try outdoors with good lighting,switch to tele lens and then cover this lens with your finger.
Not sure why the software has to decide which lens to choose, May be this is the so called AI camera feature
Try gcam. It uses telephoto lens even at night
Hey, if you want to force the use of the telelens lens long press the little tree button, and it will show a live mini-preview of each lens. Choose the tele view and take the picture. You'll notice the difference in the quality and stability of the preview opposed to when you try to scroll smooth past 1.9x zoom.
But you won't be able to do anything else but snap the shot.
As soon as you click in something out of this preview option, whether to adjust exposure or anything, you'll notice you'll leave the telelens to the main sensor 2x digital
It's not ideal, but Works... Looks like a.... Bug?
Know this has been dead for a while but I investigated this and it bases the lens selection on focus distance and light availability. If you try to use the tele lens on close up subjects it will auto select the main sensor. If used for shooting more generally the tele lens is selected. I imagine light availability makes a difference too. I wish it wasn't blocked in manual camera mode though.

Question Telephoto Camera Not Activated

I've been using the camera and testing it for the past week. I've noticed that the 4x rarely ever activates and the phone uses the main camera with a digital zoom instead. This is consistent in videos too which defeats the purpose of a telephoto lens. Anyone else with similar experience?
I also noticed this, it has something to do with the focus and the lighting conditions. Try to vary your position/distance and you should be able to easily notice that. The phone decides on its own when the transition to the periscope lens is to be made. So sometimes it works when having 4x zoom, sometimes it only activates with 5x. Sometimes it's even a little bit less than 4x. Hopefully Google will add a manual control button later on.
No matter how good conditions are, the 4X camera lens never gets used in video mode. Anyone else with same?
The way it determines it is based on the focal distance. It's unable to focus below a certain distance so when you are too close to the subject it will zoom further with the regular lens before switching over

The 4x zoom will only activate if you have 30 fps selected and possibly only with 4K, I had the same problem initially. Definitely should not be this way though.

That must be why all of those reviews were shot in 4k30. I kept seeing that in every single review video, and I wondered why.

I had this when using the slider to get to 4x but if i use the 4x button it always selects optical.

Question No zoom lens until 5x

So I noticed that the zoom lens only activates at 5x zoom. You can see this by covering the lens with your finger and zooming in.
I gather this must mean that the optical 4x lens is fixed at 4x, but as it only kicks in at 5x zoom you can never get 4x optical zoom shots as it is cropped to 5x ?
This would also mean that up to 5x zoom you are just getting a digital crop of the main lens?
Am I missing something here? Seems a little weird that you cant get a 4x optical shot with a 4x optical lens fitted.

Googles periscope lens doesn't kick in a "fixed" manner, it uses an algorithm (ambient light, shaking, distance to object etc) to decide "on its own" when to kick in the dedicated zoom lens. You can easily test this out/replicate this by lowering the light in your room/and or change your distance to your desired object and see that the point where periscope lens kicks in, changes.
Best just try to focus on the amount of details you can see, if you play around with it, you can quickly see through the Preview when periscope kicks in, since that will improve the amount of details in your preview window significantly.
Many people here want "fixed" values, but as of now, Google doesn't offer that.
This is also a big problem in reviews, since those people don't know about this limitation and you can often see a "here, 4x shot, not looking good" and my eyes tell me "jea, that's a digital crop, you m*ron" and none are the wiser.
So your saying you never know whether you will get a crop or an optical zoom shot at 4x, this makes the 4x lens pointless imho.
Google are basically stopping you using a feature of the phone whenever you want. If every zoom shot is a gamble on cropped or optical, decided by the phone, surely they are stopping you from getting the best performance from the camera every shot/zoom length.
If I choose a 4x shot I want optical every time or I may as well have bought the 6 instead of the pro and saved some money.
The deciding factor on whether it's digital zoom or the telephoto lens is the distance of the object. I estimate the telephoto lens minimum focus distance is around 4 feet. As you go between close and far objects, you can see the stutter between the digital 4x and telephoto 4x. You could always cover the either the main lens or telephoto and figure it out too. What they really need to do is add an icon in the camera app that lets you know it's 4x digital zoom or 4x telephoto.
This isn't something that's only unique to the 6 Pro.

The threshold in the HAL is at about 4.3x provided that all the other requirements for the switch are met. You can see the image "jump" slightly when it crosses the threshold because the image characteristics do not match perfectly. So yes, you can definitely tell which sensor it is using.
The reason why they don't alert you to which sensor it is using is because they (gooble) think they're smarter than you and better able to pick the right sensor.
Another thing to keep in mind is if the 4x telephoto was the default, anything too close would be immediately blurry. Then how do you switch to a digital zoom?
They could just give us a way of selecting the lens in use manually. Instead of treating us all like idiots.

Good luck with that. Truly given the way the entire world is being run right now, its pretty clear that the vast majority of people *ARE* idiots. And that is putting it mildly. So best way to make money is to sell to the majority, who are stupid enough to trust government -- those people clearly can't think for themselves.

It's worse on video. I took a supposedly 4x video of my dog and it looks terrible. Pixelated, oversharpened and unusable.

Do you have 4k60fps enabled?
For some odd reason, Google only allows the dedicated sensors to kick in if you use 30fps, since both the ultrawide and Tele module do not support 4k60fps.
So if you zoom in whilst having 4k60fps enabled, it will always be a digital zoom.
This is one of the most annoying features. The 4x lense can focus as reasonably close range but the "ai" deciding to either crop and main lense or switch to the periscope is crap.
You can trick it by switching to 4x and focusing on a distant object and back again and hope it's just within range.
People ask why use it so close, but the 4x can really aid in composing a shot without the wide distortions.
Another issue is if you adjust anything like HDR or temperature on the main lense and switch focal length to other options it doesn't switch to the actual lense you want anymore!!

You can't use the telephoto sensor for video. Only the other two.

In my book, that's an idiotic "feature" and is in fact a bug.
It makes zooming in day-to-day use unusable in most common cases.
When I zoomed to 4x and took a video, the result (1080) was not usable. It's a joke.
I think the conclusion here is the entire camera system really needs work. The hardware is better but the software is letting it down. Jerky transitions, bugs and a processing algorithm left over from the lower quality sensor days that actually over works the 50mp images.

No, you can. I just tested it by setting it to 4x, making sure I'm focused on something far enough, and blocking the telephoto lens does block the picture.
Just discussing this elsewhere, with regard to the MWP GCam mod. This is a *serious* improvement over the stock app; the one thing they could do to make it perfect is give you control over when the periscope kicks in. If anyone here knows the people working on this, please mention this. The mod is here, btw — you really should try it! The version you want is 8.3.252-V1c_MWP:

That may not actually be an option. The hal only presents one logical camera on that side of the phone and transparently switches between the sensors based on the level of zoom requested, and an assortment of other data.
I haven't looked into what the hal looks like, is it open source? If it is, presumably it could be modified to present 3 or 4 logical cameras (I.e. 3 individual + 1 combined).

How is it an improvement?
Testing zoom, it still uses the main lens on 1x, 2x ad 4x. Just like the stock camera does.
This is another reason to dislike this phone and to recommend against buying it.

Question What is the zoom lens for?

Hi all. I am debating the switch from the regular 6 to the pro.
Looks I will be getting bigger higher refresh screen (pro) which is curved (con) and with worse battery life.
One thing that is not clear to me - is the zoom lens used in any other situations than when actively selecting it? For example - which of the lenses is being used when you select the portrait mode in the camera app? Is it using the telephoto lens to battle the fish eye effect?

I have never gotten the telephoto lens to show up in gcam. Only the 50MP wide cam and the 12MP ultra wide cam. The 50 gives you zoom options but the 48MP telephoto never shows up

It's a 4x telephoto, which is a lot for portraits (so portraits are taken using main camera at 2x magnification).
No, it's not being used for enhancing ultrawide. I suppose it's also because if the same reason mentioned above (OnePlus uses it's 2x tele for this as well).
Telephoto is really only useful for zooming 4x and up all the way to 20x, when photos are still kinda useful (depending on a scenario), thanks to being a 50 MP sensor and some Google's AI magic.
I take a lot of zoomed pictures and I don't mind curved display. Battery is okay, 6 hours of SOT are real for me, usually on social networks and news scrolling. Sometimes I play a League of Legends, than it will drop to 4-5 hours.
Zoom lens is for... zooming in. I would think that would be self-explanatory?
It kicks in when the magnification reaches about 4.5x. Switching between sensors is exclusively a matter of changing the magnification level, not by "selecting" a particular camera. There are other details considered before switching sensors, such as exposure requirements.
You can tell which sensor is in use by briefly blocking sensors with your finger. When you see your finger on the screen, you found the sensor that is in use.
Yeah, thanks
What was not clear to me was if it is being used when shooting portrait photos, as some phones (e.g. Oneplus) do.
Looks like this is not the case.
I will stick with my vanilla 6 then, not missing out on much, subjectively.

Portrait photos can be made with ANY lens, depending on the distance and direction to the subject(s).

Is it so? How does the portrait UI looks on Pixel 6 Pro? On the vanilla pixel I have the options to shoot it in 1x and 2x only. Does the pro version offer a higher magnification, using the zoom lens instead of main one?
