[Q] Selective focus more miss than hit - Galaxy S 5 Q&A, Help & Troubleshooting

Hi Guys,
Is it just me or is selective focus not all its cracked up to be when shooting a toddler. I understand that they move around alot but even when my little one is standing still 9 times out of 10 I always get the message that focus could not be applied.
The way it blurs around the edges of the subject can also look a little underwhelming. I know that its not a full fledge SLR but i thought it may have been a little better.
Anybody else experiencing similar issues.
See attachment to see what I mean.

I struggle to get it to work, but if it does work, I don't get the blurry edging as on your pics. I have seen some reviews where they comment on the same issue

I agree, it seems that the feature is designed to identify objects which drastically contrast from the background. For example a a yellow bottle on a white background mostly likely will yield a failure. However a red bottle on a white background would pick up more accurately. You have to mess around with the camera to learn how the selective focus works.

Well it is a software trick and in the end it will never match the BOKEH you can achieve with a DSLR.
With that said though, I find it helps to have an extremely obvious foreground and background in order for the effect to be applied. It can be sort of hit and miss with moving subjects though.

Noise in pictures

I'm wanting to find out if the noise in some of the photos i've taken is normal for the HD2
I expect noise in a camera like this, it's just the nature of having such a small high mega pixel count sensor, I just wanted to find out if what im experiencing is normal. I've got a week left on my 14 days and would like to exchange it if it's not normal
This is probably the worst of them all that I did lastnight
http://twitpic.com/1cs2cl/full Look at the banding noise at the bottom of the frame.
http://twitpic.com/1cs4lj/full This one has some too, but not as bad as the other
http://twitpic.com/1cs50y/full This one looks like it may be a optics problem, look at the red halo around the sykes sign. the 1st time i took the pic i though maybe there was a smudge on the lens so i wiped it and still had the same result
Perfectly normal.
You're taking pictures at night and even standalone digital cameras would struggle to take a decent picture in those conditions.
The Camera will be ramping up the ISO which increases the noise anyway (and as you pointed out coupled to a small sensor just isnt great), the only way to take a decent picture with noise that isnt noticable is to use a tripod, a very small aperture and a very long shutter.
This, being a phone, doesn't have the luxury of that kind of control.
Just take pictures during the day and they are decent enough.
i get it too, including the exceptionally bright flash that usually washes out most photos, just have to live with it im afraid, or fiddle with camera settings, see what happens, but you'd have to constantly change them between night and day....
Thanks, Yeah i expected the noise in pics from the phone. Just the banding was concerning me a little bit.
It actually does pretty good at night in certain situations, there are more pics on my twitpic account from last night that came out ok, very little noise, though a bit more blur. im guessing it probably picked a lower ISO for those.

I have to agree, the camera on the HD2 is outstanding in the daylight, nearly rivals the Sony T33 that ive carried around for a long time for quick snapshots. I just wish they could put a small optical zoom on the camera, even something as small as the 3x optical zoom im used to the with T33. im sure that's asking a bit much with the space constraints within a phone. Im still happy none the less.
The camera in my old Wizard was worthless, i barely ever used it. It was passable outside on a bright day, useless under normal indoor lighting conditions or darker.
Found myself in several situations where i wanted to take a pic but didn't have the T33 on me. HD2 = problem solved =)
I just noticed that there is a TMO USA HD2 specific forum. Since this is about a TMO USA HD2 could one of the mods move this thread over there? Like to see what kind of response i get from other USA version users

Are there apps that take better photos and videos than the stock Camera app?

Hi, I don't know how various settings affect the results. However, I wish to be able to take excellent photos and videos under different conditions. Are there any good apps that take better photos and videos than the stock Camera App? I am using GB. Thanks

Might be dependant on hardware cause of varying quality pics

In photo 1, I do not know why the ceiling lights are like that.
I changed various settings but there was no improvement.
In some cases, the overall color of the room changed.
In photo 2, the room appeared to be dark but it was not.
I changed the flash to auto, on along with changing other
settings. The room still appeared to be dark.
In photo 3, again, that place was not dark. Setting the flash
to auto or on did not help.
In photo 4, everything including the room appears to be somewhat yellowish.
In reality, the wall is white and the pillows are gray.

Thanks for the suggestion but I am not a professional. I don't know how various settings affect the results. By the time I have tested out various settings, things that I want to capture will have been gone.
ah now things are getting clearer . your pictures looks a little bit like something is wrong with the 'white balance' of your camera. so you can try different settings for the white balance, the default should be automatic (AWB). I'm not an photoexpert too, but maybe some one else can guide you further with this.
Thanks for pointing this out. I also tried white balance but it did not help. Perhaps I did not do it properly. Hoping somebody could provide some tips. Are the strong glares from the ceiling lights in photo 1 also caused by the white balance?

This effect on the ceiling lights is due to a hardware fault, there are no settings within the phone that can correct this. You can try, like me, and use photoshop. For me, its no problem because I have used photoshop for many years, but others are not so fortunate. This fault is well documented. Samsung know about it, yet have done nothing to correct it. The only way is to send the unit back to the retailer for a new unit. I tried three or four brand new units and they were all the same.
In general. The camera has limitations because of its size and proximity to other circuitry that may introduce noise etc. Its 8megapix with a tiny lens, so as is, I feel it does a pretty good job (apart from that pink dot that is). To get better pictures, consider post processing with photoshop. If that's not an option, and quite frankly I would not recommend purchasing it just for pics from any camphone, try the GIMP, its free and does an awful lot to enhance your pics. You can find the GIMP here www.gimp.org it will run on linux, windows and the Mac
Hope that helps
So, getting something like Camera ZOOM FX won't help.

Good question. I know the S2 does, and we all know about the Galaxy Note. I can see evidence of the problem on a slashgear.com presentation, and its that presentation that stopped me from going over to the S3. However, there are plenty of youtube tests where it seems pretty good. The S3 has only just been released, so it might be a while more before any issues become apparent. I think its one where you try before you buy. Personally, I'm not touching either the S3 or the 'Note until I have proof that the issue has been resolved.
Edit. The fault is commonly known as "the pink dot"
In photo 1 was the lens clean? Might sound obvious but even the slightest bit of grease or diet can affect how sources of light spear in photos. Typically in any photo I take where I light bulb or something similar is in the picture if the lens was not completely clean I got a similar effect as in photo 1

Well, there must be a lot of pink dirt around. My crappy clam phone must have pink dirt repellent, because no matter how greasy the lens gets, pics from it don't have a pink dot. Neither does my DSLR when the uv filter gets filthy, or my specs come to that. Sorry, but the dirt bit on this issue is a red herring. The camera has a defect.
I use UCam. A lot of "pro" settings and also some cool. And... you can disable shutter sound.

i think you should send the device to service/repair, because i think this is an hardware issue. i saw a lot of pictures taken by the note (not only my own device) and they are al just fine with the standard settings.
I just noticed that there is a protective film covering the back camera. Probably Samsung put it there to protect the lens. Do you think this is the cause to all of my problems? Am I supposed to remove it? For the first few days after purchase (3 weeks ago), the Note took excellent photos. As for last week and the week before that, it depends. The thin protective film has been there right from the beginning. Let's say the protective film covering the lens caused the pink dot, how do you explain why the cafe in photos 2 and 3 appeared to be dark whereas in reality, it was not. Also, photo 4 looks yellowish overall.
Hi,
Protective film would most likely create the effect on pic one. (which would be visible when a direct light source or reflection is in the frame.)
Pic two - could be a metering issue. Try changing the (cog wheel =>) metering setting and / or exposure level.
Yellowish photo is the result of incorrect "white balance". Change the white balance setting to incandescent.
I'm using both the stock ICS camera and camera zoom fx. On my previous phone the fx produced much better photos than the stock one. On my G - Note I don't see much difference.

Yes you are supposed to remove it. It does say so in the instructions that came with your phone. Check the camera after you have done this.

[Q] Line in Photos

Has anyone noticed this in their camera? You take a photo in low light and a line appears near the edges of your photo (only after you've shot it). I can consistently reproduce it. I'll get mine RMA'd, but was just wondering if it was just me or do other people have it? It doesn't show up at all in more well-lit conditions.
A couple more for Christmas
It seems like a software issue to me, making me think that maybe other people have the problem too. One of these shots shows lines on both ends
I just took a few quick photos with mine and I don't seem to be having that issue either. Have you tried restoring it first?
Weird, I get that too. Only in very dark conditions though. Not really bothered about it though tbh since low-light shooting is something I'm definitely avoiding with this camera.

Nothing seems to fix it. I've called for an RMA. It's worrisome that OverTheBelow has it too. I think everyone should check. The way I've been able to reproduce it is to have the camera take a picture of a dark area (not pitch black) and make sure either the top or bottom (whilst holding it in portrait) is completely dark. So the image you capture has to have something slightly illuminated in the middle, but the edges are black.
I just tried it on another Nexus 4 and got the same results unfortunately. Is this a common issue? Has anyone else experienced it?!!

HTC one great phone, lacks focus

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?

V20 Bug - Purple Shadow when Taking Night Pics with Wide Lens

Hi Everyone,
Have a look at attached example image to see what I mean.
Please try to take a manual shot with your wide lens in a very dark environment with very high ISO (3200 in example) and exposure time of 5secs plus (20 secs in example).
Everyone who has tried that so far has the same issue, a big purple shadow on the top. It's most likely the laser and it won't happen with the normal lense.
Do you have the same result? Any suggestions what we can do about it?
Whoa! I haven't seen that in a long time. I think maybe around the time of the Nikon D80. I can't currently try this out personally but by the sounds of it what has happened is called Amp Glow. It's when you kind of start getting out of the bounds of what is really acceptable shooting conditions for a given sensor. In this case, if you really are shooting in conditions that call for high ISO AND still need a shutter speed of 20 seconds and the image still comes out that dark, then you're way beyond realistic expectations for shooting with a cellphone. In the older DSLRs, people would see it when doing star trail photos that were 10 minutes or longer. Frame stacking software became the solution to this problem by taking a lot of shorter photos and stacking them up and pulling through the new dots of light. (And this is still used by a lot of photographers as it also gets rid of other forms of noise.)
So what is happening? ISO is pretty much the gain. It's the amplification being applied to the signal coming off of the sensor. Ideally with ANY camera, you want to stay as close to the base ISO of a given sensor. That's usually the lowest ISO number. (There are some exceptions where some camera manufacturers have done some trickery to get a lower ISO to show up but that was short lived as it didn't really help things.) Unfortunately, image sensors are not hanging in space. They're packed in with a ton of other stuff. Stuff that gets warm. If that stuff is near an edge of the sensor, that heat bleeds into the sensor and then those warmed pixels get amplified by the higher ISO and next thing you know, Amp Glow. Well, that's the simplified version at least.
A cellphone, any cellphone, is not designed for those kinds of shots. If they were, they would have a tripod mount, a much better flash, and a much larger sensor. (Yeah, the flash on your cellphone is not meant to light up stuff much past 5 feet. Even the ones built into a DSLR aren't meant for much past about 15-20 feet.) The reality is that cellphones are designed for handheld shots with decent light. Even the larger sensor used in some cellphones shouldn't be expected to pull any miracles that top end DSLRs are just barely pulling off cleanly. For that shot, you would want to use a dedicated camera locked down on a tripod using base ISO and long exposure at the very least. Although, personally, I'd probably just take a pass on that shot.
someone on reddit has the exam same issue with the wide angle. and someone said it's in the regular too. weird. my s7 never had this purple hue when I did even 30 second exposure at night.

something obstructing the lens maybe, or just camera went bad
Better hope this isn't the same problem the HTC one m7 had with the purple haze. The culprit was a light sensor on the camera would overhear and give a purple haze on the screen in low light. Place the phone face down and with the camera on and see if the purple comes back.

No, it won't happen with the same ISO/Shutter settings I took the previously attached photo. But maybe that's because it's not dark enough. Did the M7 issue only happen in dark enviornment as well?

Yes the m7 only happened in low light / dark environment. Do a Google search for HTC one m7 purple haze. What caused me not to buy another htc phone

No, it won't happen with the same ISO/Shutter settings I took the previously attached photo. But maybe that's because it's not dark enough. Did the M7 issue only happen in dark enviornment as well?
Thanks a lot for the detailed explanation. My question here would be, why doesn't it happen to other phone-cameras with similar settings?

Settings aren't the only part of the equation. The other par is the placement of other components within the device. I need to look at the tear downs to see how the various parts are placed next to each other but something is heating up and passing that heat to the sensor. Just off the top of my head there are four parts together; the two camera sensors, the laser focus module, and the flask module. Each one of those on its own will generate heat if used enough.

It's the same issue. I haven't looked at the HTC issue but from your description of it, it's the same. Amp glow is what it is called in digital photography. (OK, silly that I said digital as you don't get amp glow in film.) The glow will show up because there is no other data coming off of the sensor for those pixels and the heat is amplified as "data".

Ok, just watched the JerryRigEverything repair tear down. The flash module sits right next to the wide angle and the laser focus next to the regular sensor. There is no mention as to what is sitting next to the sensors on the main board but I see silver boxes on each side with one having some sort of black and yellow warning sticker. Not sure what they are so I can't rope them in as culprits. So for now, I'd say it's a combo of the four units of the camera assembly.
Were you running the flash or one of the cameras a lot while you were playing around? Shooting a lot of long exposure shots in a row?
I'll get to test out some night shots and video tonight at a lighting ceremony but I'm still not expecting to shoot 3200 for 20 seconds type shots. Again, that's pretty extreme.
