Camera seems too zoomed in? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

No mods on my s4. Stock camera. All the way zoomed out, it feels like its too close.
So for example, if i wanted to take a picture of a 36x36 painting, i have to be farther away to fit it into frame than my s3.
Has anyone else noticed this?

Yes, it is because the FoV is different on the lens. (field of view)

Thats the word i was looking for....
So im guessing this is not like quake 3, where i can adjust the FOV?

Not at all, its mostly because the megapixel count. cameras in phones cant have such a high pixel capture and great field of view all at once... yet

Okay, thanks.
I just noticed it was very hard to take a full framed picture in a tight place.
Oh well.

On that note, could you just lower the RES to achieve the wider FOV?
Since the lense is better than the s3, the picture should still look better.

Not sure its the solution your looking for, but try using the panaroma mode... Its a pain, but theoretically should work as long as you dont need flash or anything.

Thanks for the explanation. I had forgotten the field of view is smaller on the s4. I was trying to tell my wife that the camera looks too zoomed in all the time. The Optimus G Pro has a better FOV than the GS4

Well, it's not quite like that. What you're seeing onscreen for the S4 is the aspect ratio of the pictures you're taking. So, you're getting an accurate representation before you take the photo. It's not anything but how it should be. The camera even thoughtfully has the aspect ratios of each megapixel setting in the settings menu. If you select a 16:9 setting, you get full screen because that's the aspect ratio of the S4's screen. 4:3 looks cropped because you don't want to distort your framing when you're lining up your shot. Just to clarify, this is a good feature, and not a bug.

No. This issue being raised is field of view, not aspect ratio. The field of view on the GS4 is smaller than on some other camera phones because the equivalent focal length is longer. A smaller field of view is not better or worse, it is a matter of personal preference. With a smaller field of view, things will look somewhat closer and close up portraits will look less distorted. With a wider field of view, you can get more in the picture, but close up portraits will have distorted, somewhat cartoonish look. This is because there is more perspective distortion as result of squeezing more in the frame. For reference, the S4 has a equivalent focal length of 31mm, the iphone 5 33mm, and the HTC One 28mm. So just on the basis of field of view/focal length, the iphone would the best for close up face shots, the HTC One, the best for fitting in the most on the screen, and the S4 in between the two.

yeah i'm a little disappointed because i like wide angle. but as long as you can take a couple step back, its no problem.

Camera Fix for the HD

I searched for a camera fix for the HD camera with no success. Does anyone know if there's going to be a fix in the near future? I'm sure that ya'll have the same problem that I do. Camera takes pictures that look old & rustic. Brownish tint to them & not very sharp for a 5 MP camera. I have adjusted all the settings for light & junk but nothing fixes it. As far as I'm concerned, it should take pictures IDENTICAL to a normal 5 MP digital camera. I can promise you that it's not doing that. Any help would be great, thanks in advance.

Why should it take pictures identical to a 5MP camera. The lens on the front is going to be vastly different, the sensor maybe 5MP, but what is the spacing on the sensor pixels? The closer together, the noisier the image. Colour balance will be down to the sensor too.
Regards
I'm not talking about the front camera. The normal camera on the back. I understand about the pixel thing, but it still shouldn't be so brownish, right? The pictures look like an old Polaroid picture. You know, the one's that spit the picture out as soon as you took it. Old, brown & nasty looking.
My pictures come out fine...
Hmmmmmmm...................... I'll just keep playing with it.

I'm not being flippant, but is it possible you might have a dirty lens?
Lol, that was the first thing I tried. Cleaned both sides of the back cover & cleaned the lens on the camera. Good idea, though.
The "5mp" doesn't really mean much, as stated earlier, if the sensor and lens are poor quality. As far as I know, HTC haven't released a phone with a reasonable quality camera, yet.
I bounce between different smart-phones (just coming back to WM now, after a year with S60). I can say that many of the S60 devices (in particular the Nokia N95, but also the N82 with Xenon flash) have very good cameras, being similar to low-end digital cameras in daylight. They lack optical zoom and tend to over-compress images, but have good quality lenses.
imho hd camera is excelent
pictures look old & rustic only if you make them inside house without using the artificial light setting, and this is also a general rule, not specific to HD.
Never seen a good phone camera yet, including the latest 8mpixel ones. They're all terrible.
Never
This camera will NEVER take pictures anywhere near what real cameras do. The photo sites are so tiny, they are smaller then the length of waive of light. Therefore noise, lack of dynamic width, etc. No patch will ever fix that. Sorry
open back cover , clean the lens , you will see a huge difference in quality

Not that I'm doubting you or anything but you do realize that the back cover only has a hole through to the lens?
You might try setting the brightness higher:
If you touch the small rectangle near the bottom right side of the screen (when holding landscape)
Then select the gear symbol, then select brightness from the menu and hit the "+" until it looks better that will remove most of the darkness.
The camera is a plain disappointment. In the time the camera autofocusses, I could have bought a Sony Ericsson C905's, create a good looking photo (with xenon flash) and upload it to imageshack.
If 'your object' makes the slightest move, your photo will be blurry . This is also the case when you attempt to make a photo of someone that isn't aware he or she has to be waiting for the autofocus lag. Head moves >>> blurry pic.
iPhone camera shots are way better quality, don't ask me why. Overall my Touch HD scores 8/10, where atleast 1 full point is taken up by the camera
and it's better don't speak about the very laggy video recording

Too many megapixels on a tiny sensor = major noise problem = blurring from denoise.
Even 2mpixels is too much for sensors this size, but people buy on marketing numbers of megapixels, not quality. You can just imagine the whining that would occur if the Touch HD came out with 1.3mpxiels, even though it would produce better pictures.

hehe, thats true.
mpixels dont count as much as the general public belives. the more mpix. the higher rezolution you can print the picture in. but for ordinary photos, 1.3 mpix would be enough, as long as the optics is good.
Personally, I rarely use a phone camera.
I use either my Olympus 720SW or Canon EOS.
​
the camera sucks **** compared to the n95 and the video recording is horrid. i know it's not meant to be as good as a dedicated camera but this is pretty bad given the price of the device.
i concur with mach03, move the camera a slight bit and eveyrthing gets blurred. one way i've semi gotten aorund this is to unlock the burst functiona nd take a sequence of pics and hope one or two coems out alright, not the most economic way to do it though...
i would ahve thought that maybe there's a way to tweak the camera to stop the blurring or even affect how much light is picked up by the lens which should also help with clarity

nice camera, but...

ok, i'm quite satisfied with the nexus 4's camera but yesterday when I was comparing shots with my friend who owns an htc one x, i got a little bit jealous as her pictures had a wider angle lol. when she previews pics, it really occupies the entire screen. so are there any apps that can help me get wider angle pics or is it a hardware limitation? because my friend also showed me that you can change the pic dimension from 4:3 to 16:9 in htc's stock camera app, and i can't seem to find that in my camera app.
Try Camera MX. It's set to 16:9 by default

If you're talking about the screen, I agree our N4's view angle is nowhere near HOX. And there're no software could help that, it's from the design... pixel arrangement or something. Your another point, when viewing in Gallery, I also note that the portion where statusbar located is wasted, we can't use full screen. This happen to JB gallery while ICS gallery also use statusbar space. I'm not sure what the reason behind this. If you like, you can try QuickPic... it might use full screen, but I still think stock gallery is better.
edited: Pardon me for I confused "wide angle" with "view angle".... just ignore my reply then
AW: nice camera, but...
16:9 just crops the pic. You can just zoom to achieve the same. Sensors are 4:3 so it will just worsen the quality.
The other thing is the focal length. I won't go into detail as it is explained enough on the web, but the nex has a fl of 33mm in 35mm equivalent and the hox has 28mm which means it has a wider angle, thus getting more covert, but it also has drawbacks.
And btw, this is an interesting post:

Haha, if camera's that important, should have switched, or get a hand-held on the side, I guess.
discovered another flaw today. the screen of htc one x looks much more vibrant than the nex4.
haha i still love my phone, it's blazing fast and i know it won't easily get obsolete. But I wish review sites pointed these weaknesses out.

Hox screen is over saturated. N4 is more accurate so less punchy. I have both to compare against reference images.

Heh heh... with all other things being equal, there is essentially no advantage/disadvantage to either of these two focal lengths. It simply means that when composing the exact same picture, The nexus 4 will need to be a little further away than the HTC. Conversely, your friend will need to get closer. Sometimes it is easier to do one than the other, other times not.

Lines get bent. The wider the angle the more fisheyey it gets.
But that's the extremes. I just realised poster before me essentialy said the correct thing for this exact use case.

S4 camera is really blurry?

Hi there, not sure if this is a common problem or not.
Whenever I take a photo on the phone it appears okay, but when I start to zoom in it comes out really blurry. The camera's set to 13mp and even on 9.6 it's blurry too. Is it like this for everyone?

Well... I think I get what you mean, and it has to do mainly with the resolution of the screen. When visualising pictures in a FullHD screen (2MP) the available real size is "only" 2.5times the display size on each direction. (Screen is ~2kx1k, 13MP is ~5kx2.5k pixels). And when you zoom in you quickly reach (and surpass) the real (sharp) size.
With an old phone (say 800x480) you had plenty of zooming to do before reaching the 5MP size.
The complementary reason to this is that the camera 13MP sensor is not proportionally sized with respect to good 8MP ones.
Having said all this, I find the quality of the S4 pictures to be OUTSTANDING for a mobile device.

I usually leave it on Auto Mode although some times I do have to lower the ISO level because it tends to like high ISO values unnecessarily. I'm not a Pro photographer though.. there's probably some thread about tips and tricks to get the best out of it.

Ohoto Aspect Ratio 18:9 is Just a Crop?

Just got my G6 and was looking at the camera settings and noticed the 18:9 default aspect ratio of photos was an 8.7MP photo and 4:3 is 13MP. Well we know the sensor is 13MP, so obviously anything wider than 4:3 is just a crop. So correct me if I'm wrong but choosing a wider photo ratio in settting isn't going to give you a wider field of view, all it's going to do is crop out the top and bottom of actual photo the sensor is registering which you could easily do in a photo editor. But you can't put the top and bottom back in, if you set the aspect ratio wider than 4:3.
So what is the idiotic thinking behind defaulting the camera to 18:9? I'm guessing the average user might be upset that the photo is not taking up the entire screen on their phone. It's odd that these days there's all these tests, reviews and debates about what smartphone has the best camera, and then you have the manufacturing setting the default camera settings to crop out the top and bottom of your photo.
Yep, AFAIK, all camera sensors are round, while all pictures we got are in square shape. So, such wide pictures as 18:9, 16:9 are all cropped.

Camera sensors are not round, they are rectangular. The sensors native aspect ratio is what determines which aspect ratios are cropped.

I'm sorry, I have explain what I mean in the wrong way.
As we know digital camera*takes light and focuses it via the len (which is round) onto a sensor, and yes, the image produces by the round len is round.
And when that round image projected on the rectangular sensor, we got the rectangular picture. Using a nearly square will get most of round image made by the len.
A more wide ratio picture (18:9 for example) with the same quality as 4:3 need 2 things: a bigger len (to have a bigger round image), a bigger sensor to crop the wide section => both increase the cost and most important need a bigger camera part.
Hope I have make my opinion​ clearer. Sorry for confusion I made.

I don't remember exactly but didn't the camera say something about this when you first started it? Or when you headed into the camera settings for the first time?
I seem to recall being reminded that using 4:3 would use the full sensor at least so that would help people who aren't in the know.

Rare 'fish-eye' effect on wide angle photos

Hello mates! I've had mi G6 for around 3 weeks and I love it. But the wide angle camera does some strange fish eye efect on the borders of it.
I uploaded one with the regular mode and another with the wide angle mode to make a comparison of both.
What do you suggest? Talk with the sellers?
Thx in advance.

Yeah its normal
Haha yeah. That's how it works.
If you take a picture of a big panorama or something, you'll see it looks much better.
That's why the normal camera is used for up close normal photography.
Yeah.... wide angle lenses will have barrel distortion... that fish-eye effect... There is really not much you can do about it. Think about it, when it's taking that pic, the image it sees isn't 'flat', it's looking at a large arc, a 120-degree arc, then projecting what is essentially a curved image onto the flat sensor in the camera. Every wide angle camera lens will do this, and the wider the angle, the greater the distortion.
Now, your eye has a larger field of view, why don't we see the same distortion? Well, ignoring the fact that the human brain is one of the most powerful image processing engines in existence and will compensate for a LOT of junk, your eye's sensor, your retina, is also curved.
There are some tools you can use in photo editing applications that can reduce the distortion, and they stretch out the corners. Now, if you took that wide angle photo and then projected it on the inside of a sphere, you wouldn't see any distortion.
The main camera sensor is also distorted, but it's a much more narrow field of view, so the distortion is not nearly as prominent. But if you look at the margins of the pictures you take, you will still see some of that distortion.
