when I take a photo then view it and zoom in, the photo becomes pixelated and does the same when i viewed it in photoshop never did this on my s4 any suggestions please.....
What settings did u mess with ? Or auto everything?

Any photo is made up of pixels, so when you zoom, you will see those pixels of course, it's expected.
So I'm confused what you mean. Are you saying that when you zoomed into the S4 pictures, you never saw any pixels? That's impossible!
Perhaps it's just different software or tools you happen to be using, maybe you somehow are able to zoom further into the G4 pictures so that you can finally see the pixels, but when you used the S4 you just never got close enough to start seeing the pixels? But trust me, every single digital picture has pixels, you can't avoid it.
Are you using the correct resolution?
You can't really change the G4's photo resolution, at least not using the included Camera app. So it's unlikely the OP is shooting at, say, 2MP rather than 16MP.
But as KingFatty said, every photo will become pixelated if you zoom in far enough, that's just the nature of the beast.
The only "exception" I can think of is if you are using the digital zoom on the G4. It handles this a bit strangely, IMO.
On my last phone, as I recall, it would save digitally-zoomed picture as a lower-resolution file, reflecting what the sensor actually captured.
But with the G4, the picture will still be saved at the normal resolution (5312x2988, if shooting in 16:9). But in reality, if zoomed fully to 8X, it only captured 1/8 of the normal area on the image sensor. It only captured what was at the middle of the image sensor, then it stretched that out, "pretending" it captured 5312x2988. When in reality, what it captured is much lower resolution.
So a digitally-zoomed picture will look much worse than normal, when you zoom in using Photoshop, etc. It'a *already* been digitally zoomed in once, when it was saved. If using the digital zoom, you may as well just take a normal picture, then crop it down later to just what you want, it's the same end result.
This is why I never use digital zoom on anything. Cropping the final picture will always give you a better result than digital zoom since the digital zoom also effectively cancels any image stabilization in use.
How far area you zooming in? If you look at a photo from a DSLR at 100%+ you easily see the pixels and you can see how soft the photo is.

hello
Is there any way to improve the camera's zoom?
it can improve a rom?
photos are very nice but the zoom is not clear and very weak
B.R.
Dont think there is a way to do that. If you want good zoom probaly better off with a actual camera

The short answer is no. Your phones camera, like most smartphone cameras only has digital zoom. This is essentially the same as cropping an image using photoshop or some other photo editing software.
If you want to be able to zoom and have crisp photos, the only option is to buy a camera with OPTICAL zoom.
As a rule I have found you are much better off ignoring zoom on your camera completely, and editing it later on, and if you do use the digital zoom feature, use as little magnification as possible.
Any software updates/changes could the algorithm slightly, and in my opinion, it rarely makes much difference, and being Sony has a digital camera/SLR arm (they also bought Minolta a while back), I would suspect they have tweaked for quality already.
I ask because I previously used the desire hd and there was a very good zoom

DHD camera is not as good as arc in the first place, and the zooming function make it worse..
I had a DHD with 2.3.4 rom and zoom was very good and clear
Take the photo and zoom afterwards with a pc or an app if zhe zoom of the cam isn't good enough for you.

I agree that digital zoom is not as good as optical but it has its used on the Xperia ARC. You will actually get me details zooming in than taking a full size picture which you enlarge later on.
Try the following to test this, it will only work on motives close by. Place a book 1-2 meters away from you. Take a full size picture and then take a one where you zoom in on the book. You will actually be able to read the text on the book on the zoomed picture while the enlarged full size picture will show the book as pixelated and it is difficult to read the text.
There is no difference on motives far away between the zoomed picture and enlarged full picture.
I am not sure why the objects close by contain more details when zooming than enlarging a full picture. My best guess would be that SE has some logic buildin on the photo chip that on the zoomed picture correlate pixel readings on the sensor and not just cropping and enlarging the final picture.
Please let me know if you experience the same, I am very puzzled that the zoomed picture for objectives close to the camera contain more details than the full size picture.
Lets put ugly black bars on the sides of all your pictures while giving you gorgeous 1080 video capture.. Okay seriously, any chance the stock camera apk can be modified to allow widescreen photo capture?

You mean instead of taking full 5mp photos, you want the camera app to crop the top and bottom of the photo and downscale it to 2mp? Because thats what 1080p is.
When viewing a picture on a Widescreen monitor, an HDTV or our phone's screen for that matter, 16:9 just looks better.
Anyone know if this is on the to do list, or if there is a way to do enable this on the stock camera app?
Surprised the camera doesn't default to 16:9. Most phone cameras haven't used 4:3 in a long time.
zoom in on the photo if you're bothered, I'd rather have full resolution and make full use of the 4:3 chip inside than having some cropped off.
It's as bad as the people who moan when DVDs, Blu-rays and film channels (at least here in the UK) show films properly which means there's black bars at the top and the bottom, I'd rather see the whole thing that have some edges chopped off!
Whats also interesting is if you take a picture while recording a video in 1080p or 720p for that matter, then those shots are in widescreen.
Forget which quality is better for a second and think about the fact that this will lead to having different aspect ratios for some of your pictures since theres no way to force is on the Camera shots.
I dont know whether the quality is better with widescreen or not (it sounds like not) but I think we can all agree we'd rather have the option to turn it on or off.
Hopefully it comes in an upgrade or MOD at some point.
Has anyone tried using Vignette?
Yes, Vignette seems to work well on ICS. That said, I haven't found a way to make it shoot 16:9 stills. However, it looks like Camera360 Ultimate might -- and for whatever reason, it is free in the Market as I type this.

Yeah guys, VIGNETTE works well on SGN, you ca adjust aspect ratio to 16:9.
I have just purchased this and need to try how is the quality now...
but at least it works in wide screen mode, even though the effect is more or less a zomed in pictures, but the app can save simultaneously the original 4:3 photo as well. . It would be better to have a native 16:9 camera..

Most camera-chips and camera's are 4:3, including on high-end DSLRs.
If you want it to have a widescreen look, either zoom in or just crop it. It's not that hard.

Yeah, and this is limitation for capturing normal widescreen photos. For example, my previous xperia neo has 8M camera and it native sensor has 4:3 (3264*2448) or total ~8 million pixels. But it software camera has 16:9 mode which crop top and bottom lines for 16:9 (3264*1839) or total ~6 million pixels. At the end, our gnex camera has 4:3 (2592*1944) or ~5 million pixels. For cropping this to 16:9 we'll have only 1458 for height. This is totally loss information for such a sensors.
If your such a camera nazi then crop the pics to 16:9. But i agree with the people that say why downgrade quality , im sure if they did you would start a thread on nexus camera not detailed photos

It's actually 3:2. Only Olympus produces 4:3 DSLRs.
Back to the main topic, if you want to capture somewhat widescreen images OP, try Camera ICS.
It doesn't do 16:9 but 3:2, at least. It also offers various improvement.

No, it's 4:3 but there's a setting in Camera ICS that automatically crops 4:3 images to 3:2.
By doing so, you lost about 0.5mp (from 5.0to 4.5mp) which isn't a big deal.
---------- Post added at 11:27 AM ---------- Previous post was at 11:16 AM ----------
And guess what? Camera ICS also supports 16:9 (3.8mp) format.
Camera Mx, 16:9 aspect ratio
Camer JB +
Install Camera JB+ from the app store. It gives the option of Widescreen (16:9) pictures but you have to compromise with MP (3.8MP)
Hello,
I've been doing some digging around and it seems this may be related to the JPEG compression, but how can this be removed? All the "mods" i've came across are discontinued. Please explain.
Anyways, if my camera moves the slightest while taking a picture, it becomes blurry. Videos seem fine, but pictures almost always appear blurry.
Thanks for your help. :highfive:

If the images are blurry only when phone is shaken then it has nothing to do with JPEG compression. AFAIK One X doesn't have optical image stabilization, it has a digital IS mode for video, but not sure if there is anything for still photos. There is nothing much you can do other than hold the phone still and try to shoot under well lit conditions (to reduce shutter time).
Are you using an AOSP custom ROM (i.e CM10, AOKP etc.) ?
Also, with the stock camera app, hold down the shoot button and it'll take a few photos in quick succession and allow you to choose the best one
Does anyone know what the Lucky Shot feature is?!?!? I'm the only one in the world trying to figure it out apparently. I'm wondering if it is on both 6P and 5X. I know that 5x has 120fps slow motion, and no burst mode. but this Lucky Shot thing has me confused, apparently it is NOT the same thing as SmartBurst.
from Nexus enginners Q&A on reddit:
"We've done a bunch of things to provide image stabilization: 1. The Nexus 6P/5X has a large 1.55um pixel camera and the amount of motion blur due to hand-shake is lower when you have large pixels. 2. We have a feature we call "lucky shot" internally. When you take a picture, behind the scenes, we select the best of 3 bursts of images. 3. When you use video, we have optic-flow-based image stabilization. 4. When you use SmartBurst, we select the best image from the burst (for example a shot with eyes open)."
It just means when you take a picture it actually takes 3 and chooses the best for you automatically.. It's not a setting or anything.. Just something that happens behind the scenes
cool, got it, but does it work on the 5X or just the 6P.
Both

I like this implementation better than the Moto X's one. It gets cluttered with double takes of pics, thus having me to look through them to see which to delete. I trust Google to pick the best pic
But I think only HDR+ uses this feature.
Because Google advertised HDR+ with exactly this feature.
http://googleresearch.blogspot.de/2014/10/hdr-low-light-and-high-dynamic-range.html?m=1
"HDR+ also begins the alignment process by choosing the sharpest single shot from the burst. Astronomers call this lucky imaging, a technique used to reduce the blurring of images caused by Earth's shimmering atmosphere."
The one pet peeve I had with the S7 camera (I had both the S7E and the S7 earlier this year) was that the plane of focus was so narrow that large parts of the photo would be out of focus or blurry (subject and where you tapped to focused would be spot on, but rest of image would often be hazy I AM NOT TALKING ABOUT THE BOKEH EFFECT PRODUCED BY SHALLOW DEPTH OF FIELD!). I recently got the Note 7 and it too seemed to suffer from the same problem. All this is shooting in Auto mode.
However, taking the same exact shot in Pro mode (with ISO, Shutter, WB and Focus still set to Auto,) the photos come out better! It's weird, everything set to auto in pro mode should be same as Auto mode, but its not. I think it's because Pro mode gives you the option to set Focus to "Multi AF" instead of "Center AF" as well as the option to do matrix metering.
Now my question is whether there is a way to set auto focus to Multi, and metering to Matrix in the Auto mode. Doesn't seem to be any menu options.
Most likely the Aperture. When you focus on an object with the Apeture wide open (provided the aperture is big enough) it will blue the objects outside of the focus point. The phone has an apeture of 1.7 which is pretty good.

You are missing the point. I am well aware of depth of field and aperture, and what the 1.7 does. I am talking about multi AF versus spot AF and metering.

In Auto mode it seems to prefer opening up the aperture all the way for that subtle bokeh effect. It seems there is no way to override the aperture behavior of Auto (which is more aggressive than the 'auto' of pro).

The aperture does not change.
I'm pretty sure what you're experiencing is the depth of field, and having f/1.7 is an unfortunate side effect at times. The only way pro mode would be any different is if Samsung's processing is playing with focus in a less than optimal way. If the exact area you intend to focus on is 100% in focus, I see no reason that pro and auto mode would be any different.
Not being funny or anything but have you made sure there's no plastic film thing over the camera lens? Sometimes can be hard to see that it's on there. Only say that because I've not seen any examples of this happening else where like in note 7 camera review videos etc.

Yes. It does. The quoted 1.7 is maximum size. if it couldn't be effectively made smaller, every picture in moderately bright light would look like the surface of the sun. Go into pro mode, you can manually adjust from a pin point (almost closed) 1/24000 to a huge (wide open) 10.

It is a dept of field issue and they are (pro and auto) different. In Auto mode, it seems that the aperture is kept overly open and the exposure is shortened (less motion blur, more saturated colors, narrower DOF) on purpose. It looks nice. I've paid good money for SLR lenses with a larger aperture so I could make nice portraits with an out of focus background. But it's not what you always want. In pro mode you can manually adjust the effective aperture (same as f-stop in photo lingo). You can set the aperture to 'auto' in the Pro mode and it seems to be better about focusing a larger area of the photo by using a narrower aperture and a longer exposure and lower "iso" sensitivity. So Auto and Pro with all 'auto' settings appear to behave differently.
I really appreciate you guys taking the time to add to this discussion, particularly kaylorRN. But I fear you are all missing the point entirely. My original question may have been poorly worded I suppose.
I am not talking about focus blur or depth of field. I am very familiar with that concept. What I am talking about is situations when you shoot for an entire image to be in focus, but large parts of the image are still out of focus. Best to show you. Look at these photos shot with my old S7:
Photo 1
Photo 2
Photo 3
Photo 4
There is no real 'subject' in these photos, and they are not macro shots, so depth of field / bokeh / focus blur is not relevant. Those photos are normal, everyday photos where the entire photo is expected to be in focus. But you can see the S7 camera in Auto mode locks onto a very small area and other large areas of the photos are blurry.
Shooting with the Note 7 in Pro mode (with all parameters still left on Auto) seems to minimize this problem. I have a feeling its because pro mode allows you to shoot in "Multi AF" and lets you do matrix metering. Can anyone confirm or deny this hypothesis?
Again, I am not talking about depth of field / aperture.
Does anyone know if shape correction has any negative effect? I was going to use it but unsure of the ups/downs

Umm, that's shutter speed; not aperture. There is no way to control aperture because it is fixed on these phones. The phone compensates for the fixed aperture by reducing the shutter speed.
Look at the EXIF data from any picture taken with the s7 or note7 and they'll all have the same aperture. Pretty much any phone behaves the same way (the aperture may be different, but it'll be fixed).

Nothing in those photos appears to be in focus. If I had to guess, you were too close when shooting. Do you have other pics of the same things which were take at a greater distance?

ha. No, I wouldn't say I was too close. A normal distance away. And it was the same story even when shooting from far away.
Should be sharper. Looks as though the camera lens is faulty or you are causing some kind of shake. How were you holding the N7? The bike shots look as though you were reaching down and then angling the device, a very unsteady posture. Even holding the device too tightly can cause shake.

I see your point. The aperture is fixed, inadjustable. However mine seems to be on the contrary. It has a deeper DOF in Auto mode than in Pro mode (Multi AF). I did test many shots and can confirm that. Whatever results, it 's still unsatisfying to me. I 'd like to have a deeper DOF (just like decreasing the Aperture in DSlR)

I get what you are saying. I have noticed the same thing on my Note, and previous S7 Edge. I believe you are correct when you say that Auto Mode uses center focus, and Pro Mode uses multi-point. I normally use Pro Mode for just that reason.
