I've just discovered something very interesting about the S3 camera -its ability to use very -and i mean VERY high shutter speeds. I first noticed it in the EXIF data of a shot taken into a misty sun...a shutter speed of 1/10,000th second..so I decided to experiment a little to see what the shortest shutter speed the camera was capable of. I first took a close up photo of 250w infrared bulb filament with the bulb on. The result? A clear picture of the filament at 1/55,000th of a second! The highest I've seen so far is an only slightly overexposed closeup shot of the emitting surfaces of a 5w LED bulb straight on at 1/199,680th of a second!!. That's 1/200,000th of a second!!
This must be near a record for any consumer camera...now to find a use for it Filament photos becme a little boring after a while......

Picture
Note the almost black LED surround in reality is too bright to see properly by eye, the LEDs are just a blaze of brightness, not discernible by eye. Check the EXIF data for exposure.

I've never noticed much noise in my S3 camera, besides at the reduced size of the images you wouldn't see noise anyway. If you're getting what you feel is 'noise' have you made sure your camera lens covering glass is scrupulously clean?
(BTW before the noise debate rises again I have a Sony module camera in my S3, my wife's S3 has a Samsung camera module and appears to have about the same noise level as noise as mine -both are excellent for such a small sensor)
nokia n8 camera can also do that for you...better than s3 i suppose!

Here's the original shot that triggered my interest (full sized) taken with my wife's Samsung camera module S3. Not too bad for noise I think, check the clouds -the unresolved distant gravel and mist droplets look like noise but aren't.

Yeah, I agree. It's a brilliant shot with minimal amount of noise. The S3 does indeed have an excellent camera but it doesn't perform in medium to low light conditions as expected. For example, my friends and I went to a somewhat dimly lit restaurant. Let's say it was just above low light conditions. The camera took rather blurry pictures (as expected of moving subjects in low light conditions) and there was a large amount of noise in the picture.
I've attached the picture (it is cropped a bit at the top). You can see a large amount of noise on the blue table.
Actually, I wonder if the "party/indoor" scene in the camera might have resolved this issue. It seems to be doing quite a fine job on dark indoor pictures right now. Hmmm...
Really???

Hey come on now, that's low light.and I'd call the amount of noise totally reasonable for a high ISO, low light shot. The level of noise is way below the resolution of the photo..i.e.the noise is sharp the image isn't from camera shake. You're expected a lot from a phone camera. I've been a photographer for 40 years...from long before digital cameras and I'm very happy with the performance of my S3 in low light..I think it's nothing short of marvelous for a phone camera!
Samsung could have easily included more noise reduction for high ISO shots, but it would have reduced resolution, its always a trade off.
If you're worried about noise check out Noise Ninja..(for PC) with it you can select your own trade offs between visible noise and resolution on any given image.
.
Ah, okay. lol. Well, I suppose I have high expectations because I've been using a DSLR a lot for the past few weeks.
I just took a few more outdoor sunlight shots and they're brilliant! So, no big gripes with the camera.

how about the possibility that the EXIF data might be wrong? how else can you verify the true speed with what the EXIF says? shoot a hummingbird in mid flight?

Firstly experience tells me it's very bright...after all 1/200,000th @ F2.6 is roughly the same as 1/6000 @ f16 which is about 35 times brighter than full sunlight on a 18% gray card...that seems reasonable.given that it's looking right into a very bright light.
Second, I then metered it with my DSLR and got 1/8000th @ F22 at 100 ISO which equates to 1/256,000 @ F4 which is close enough for me.to the S3's overexposure at 1/200,000th @ F2.6 at ISO80
So I think it's both using a real 1/200,000th, and writing the EXIF data correctly.

yeap, but the camera is still great :good:
So, my problem is that my camera does not seem to focus an Objekt, even when I "touch " it in the camera app. It is still a bit blurry when I view the taken shot. When I look at my friends Nexus 4, colors are much better and everything is sharp. Is it possible that I have a broken camera? The settings are exactly the same...
It may be helpful to post some example shots.
1st thing to look for is to make sure that the glass covering the lens is clean. And shoot in good lighting.
Known problem, please star the issue http://code.google.com/p/android/issues/detail?id=43153&thanks=43153&ts=1359017856
AW: Bad camera focus
And the washed out colors? Max it be the fault of rev10 devices? A friend of mine said something like that
//edit
Here's a sample. If you zomm in you will see the Blurry borders. They are really annoying because when I look at the pic on a PC, I am able to notice it. Maybe it's the cameras fault or Googles fault for bad drivers and software.

It seems to me like the hardware is perfectly capable of the focal lengths to get clear focus, it's just the autofocus implementation that's broken. Is autofocus a driver level implementation? If so, would it be feasible to try and create a custom driver to at least allow for true manual focus?
There are several things that can be going on here. 1.) it ain't a great lens, so not all areas of the picture are going to be razor sharp. I see a good degree of softness in the corners.
2.) I have noticed the camera's default behavior is to use lower ISO, and longer shutter speeds in less than ideal light, making camera movement a major factor in blurry photos. If you're gonna test under less than ideal light, rig up some kind of tripod.
3.) Auto-focus algorithms decide focus based on maximum contrast. If the area of your focus reticle is over an area that has poor contrast, focus will be compromised. Low light also lowers contrast.
4.) Depth of field. It is limited with this lens. Make sure areas you are checking for focus are on/near the same plane with shots that have reasonable distance separating foreground/background objects. They all can't be in focus.
With all that said, reasonable photography skills can get pretty reasonable results from this camera, as is exhibited in the photos posted in the photo thread of the "general" forum.
It does focus, but has a small delay tho..
actually the focus on N4 is slow a little bit ..
Is there any new piece of information about the bad camera focus?
anyone else have a pink haze when capturing white objects
I mean it in a literal sense.
If you look at the image below, youll be able to see that its a bit blurry,
I've drawn 2 black lines in the image, notice that the top and the bottom is blurry and the center is focused.
It doesnt occur alot, but it does happen and sometimes even in videos.
Any help as to why? Perhaps 4.2.2 might fix this?
I think the DOF is so narrow because the lens has a wide aperture of F2.0 which helps in low light.

Can you explain what DOF is?
Is there anyway I could fix it? You think anyone else has this problem?
"depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image." - (http://en.wikipedia.org/wiki/Depth_of_field)
And I don't think it's a problem. It's just how the lens is made with a large aperture to allow more light in to the image sensor.
You could try to compensate this a bit by increasing the sharpness from the camera menu.
I'd be more concerned with the poor dynamic range shown in the top of the pic. ;O)

That`s totally normal for the one, it only exposes the focus point, instead of the whole image, could htc not have given us a choice

Well that sucks. One of the reasons I bought this phone was for the camera.
Do you know anyway I could fix this? or atleast minimize it?
The problem is when the image contains both dark and bright areas, if you focus on the bright, the dark areas will be underexposed and if you focus on the dark the bright areas will be overexposed, you need to find an area to focus on that will give you an average exposure for the entire image.
I have the same problem, but some photo`s are amazing and some are utter crap.
Try using hdr mode, it takes multiple images at different exposure levels and then integrates them into one photo, but you need to keep the phone very steady, hopefully HTC will fix this problem.

Mine does this as well. Easiest fix I've come across is just tapping on the screen in the area you want focused...it seems to hold focus better after the first time and the photos look a lot better.
Problem is, I generally forget about this until after the first picture is taken without it. So it's a process for sure.

Mine is the same way. Wasn't bashing the camera was just giving my first impression of the pic posted. I think the camera is excellent for a phone. Small sensor and tiny optics will only go so far. This device is fantastic as an overall package.

Why are all you guys saying this is normal? Either you have defective phones or you don't know how to take pictures! ... The only time my One does this is when I use touch to focus on Macro mode. I have taken hundreds of pictures and no pictures look like yours unless I wanted them to.
Agreed. The picture in the OP looks like an issue with OIS, not depth of field.
If it was a one time thing then this thread doesn't need to exist. If it happens a lot the phone needs to be replaced.

I do think it's a flaw in the camera software that exposure and focus can't be decoupled. I LOVE the shallow depth of field but can't use it property because touching-to-focus blows out highlights.

Most of these comments come from people who have no idea what they're talking about.
Your phone is perfect. Nothing wrong with it. All you did was tap to focus on the middle of the picture.
This did 2 things.
1. It will FOCUS on the center of the pic. Other areas will be blurred. Hence the term, focus. That's how cameras work.
2. The exposure was adjusted to where you focused it to. What does that mean?
If you focused on a light area the camera will adjust the exposure to compensate. What that means is if it's light, the camera will darken the overall image. Lights become darker, farms become darker.
If the photo is focused on a dark area, the camera will adjust the photo by making the dark area brighter and the bright areas, as a result, brighter. Which is why you have super white skies.
To fix it, go to the camera settings and I think select touch to capture. But to say fix means it's a problem.
It's not.
For landscapes, use landscape mode which will focus on the entire image and bot blur. Also you can tap on the area where you want adjusted, ie brighter or darker. Blur again is only cause you focused. Don't focus on landscapes.
Photographer here. Focus on this comment and not anyone who says your phone is messed up. This is why.
Take a look at my two attached photos. One I clicked on the sky and the other I clicked on the grass. Light then dark. Can you figure out which was which and see what happened to the photo?
Note that it was overcast and cloudy. There were NO BLUE SKIES. it was grey. So the sky wasnt killed by the camera
Btw don't always use Hdr. Don't. Its not a saving grace every time. If you shoot in the sun you're shooting in the sun. Photography rule #1: DON'T.
ALWAYS USE THE SCENES WHEN YOU CAN. WHICH IS WHY THEYTE THERE AND EXIST. SLRS HAVE THEM TOO FKR A REASON!
As for the lines, panorama? Did you move too fast? That's what happens when you do - camera can't stitch properly

The black lines on the image, I DREW to show where it gets blurred (not panaroma).
You're right, but when I focus on the center, all objects in the background should get blurred right? I mean thats how the focus works. You focus on a particular subject (lets assume in the foreground) the objects in background gets blurred.
If you see the image I uploaded (in the top line) the upper part of the tree is blurred and the lower part is focused.
It doesn't work like that right?
Hi everyone,
I'm having a problem with my Samsung Galaxy S4.
The front camera is producing blurred photos, almost as if they have been automatically edited/badly Photoshoped.
Before I capture a photo, the quality looks normal.
I've made sure the lens is clean and there is no plastic covering the lens. The same happens with Instagram... quality looks fine before capturing and then the same awful result afterwards.
Any help would be great!!
Anyone?
Can you post any photos you took with the front camera?

Thanks for the reply!
Here is an example.
This is on the highest possible resolution but the same thing happens with every option. The quality is absolutely fine before I capture the photo and then, as you can see, it's as if a soft blur filter is added.
Any ideas?
Bump!
I think it's because the post procesing, which tries to reduce the noise for the cost of details (blury).
Try to take some photos in brighter enviroment.

It's the camera. There's a definite lack of sharpness, and it happens on every ROM, so it's not software related.
Having the same issue.
Under good lighting, it's decent.
But under low light, or even under normal room lighting conditions, the image becomes grainy.
Even my previous S3 takes sharper and clearer images.

Exactly. I just upgraded from S2 and never had these problems. My software has just updated but with no effect.
S4 Front camera, STRANGE.
Hi,
I was having problems with my S4 trying to make an ordinarily phone call. The phone seamed sluggish and my voice did not go through once I was connected. So, I switched to hangouts. I made a video call so I was expecting to see myself in the small picture on my screen. I did see a zoomed picture in good quality? Better quality I ever had seen before! I was surprised to see a good quality zoomed picture under poor light conditions. Since I am a computer guy I realized that something is fishy so I looked for an appropriate forum to put this story in.
My question is since you are talking about a suspected software filter. Are we without our knowing it have better camera performance than we the user are allowed to use? I do not buy the ROM explanation of the problem.

S4 Front camera, STRANGE.
Hi.
I had an encounter with something, well, alarming.
I had some problems making an ordinary phone call, sluggish phone, so I switched to hangouts instead.
I made a video call to my friend. For some reason the phone had not stopped being funny. In the small picture, the one of me, I saw something I never had seen before. Instead of the expected streamed image of me I had a zoomed in version in surprisingly good quality! I could see holding my phone, S4, at 30 to 40 cm distance my mouth covering the with of the image.
Question: I looked for an appropriate forum and thread before posting. Since you are here talking about the poor picture quality of the front camera being manipulated by a software filter you might be intrigued like me about this observation I had by chance stumbled up on.
My question is whether the cameras on our phones have capabilities we are not aware of?

Hey!
I can't seem to find any samples or anyone even showing or mentioning the results of the front facing camera in any review.. From what I have seen on the z1 is that the pictures of the front facing camera are grainy like crazy if the light isn't perfect. Anyone knows if the slightly better hardware of the z2 camera gives out a better end result? Maybe anyone of you can link to some pictures on the web.
Thanks!
The front camera is just a 2mp ish camera which really all you want it for is 'selfies' which it will do the job.
From the samples I have seen Im pretty pleased with the results of the rear camera and low light pictures definately look acceptable.
Im on the LG G2 now and the camera is awesome, the pictures I take are amazing, until the light starts to fade, then it takes about 3 seconds to focus, if the object is moving its blurry and looks like a cartoon. Im just hoping the Z2 gives me the awesome pictures in daylight and ok pictures in low light which are not blured, that will do me. But as always I wont know until I test under my own uniqe conditions.
