Hi,
i have little question, did not find anything that was helpful. So, taking pictures in dark conditions. Few days ago my friend bought Sony xperia go. and, when you press camera button in dark, it turns the LED flash on, make autofocus and take picture. In that way picture came out sharp and good.
On the other side, our evo does not turn flash on, but instead it "autofocus dark image" (practically blank screen) and of course image is usually all blurry.... Is there any solution for that?

Use the flashlight or torch app to force the flash on.
now thats just to funny. you could just say to glue real camera on phone and have excellent pics hahaha

This is your best bet. I do this too when I get that stupid message stating that it can't use flash because of low battery. GTFOH.
I just tried this out. It really works well. Thanks to all the posters.
I do that too especially when taking a video at night. Just go into quick settings and turn on the flashlight!
It works best at 3 AM when everything is hilarious and you try to make a movie better than paranormal activity. Which surprisingly isn't that hard to do.

I can't seem to find a thread on this and I find it hard to believe no one else has an issue with this. In the camera on the HTC Touch Pro where the flash option is, it's "flashlight" not "flash." So you can't have the flash bulb turn on only for the picture and then turn off like an actual camera flash. What's the reason for this? Any hack to fix it?
If you use it how the Touch Pro seems to want you to...
You may as well admit the LED will burn out before it should.
i don't think the led will be burned anytime soon. have never seen a burning led. if it last for 2 year i'm happy, i would probably go a new htc by then. however i agree that having the flash turn on like that it's a waste of battery.
you know the funny part about this is i'm actually this flash as a flashlight with htctorch and it has been very useful.

Yeah, I've searched for this myself, didn't find anything. I mentioend something about it somewhere else but got no responses. Probably because the phoen was brand new and maybe not widely used yet.
In any case, LED's are rated for 100K hours of life, some may get more others less, but on average, that's their rating. Long past the noral usage of a cell phone. It does actually flash though when you take a picture.
The reasoning though (guessing) is if it's in a relatively dark room, the camera will be unable to focus properly to take the picture without it (the subject) being lit up before hand. But most people probably don't take pictures in that dark of an enviroment.
In any case, it would be better to have the actual option and let the user decide if they need pre-light or just a flash to take their picture.
hmmm.. yeah, its not a flash, its a flashlight. if anyone wants to make a hack for this to just flash, that would be so ****ing badass. that thing is so bright that peoples eyes are always squinted before the camera even focuses. its nice that its bright, but i mean, seriously.... its BRIGHT. and annoying.

+1....I was wondering too
There's a reasoning for this, at least.. the focus and metering mechanisms all function poorly in low light, so without the light on for the focus phase of the image taking, your photos would come out even worse.. it isn't the only phone i've used that behaves this way, almost any phone with a LED flash will do this, only Xenon flashes and the like will behave like a camera (brief flash on shutter release)
can Mozart's Xenon flash serve as flash light? I read some review that LED can stay on but a xenon can't since it's like digital camera flash, it fires once after it has sufficient charge. To those people with units, can clarify on this ?
I don+t have the unit, but flashlight app from HTC is not available on the Mozart (check HTC website for instance). I don't now if 3rd party flashlights will allow this, but what i know is that xenon flash must not stay on because its powerful that LED and eventually may burn the flash... So LED may be used for flashlight, but xenon no.
No, it cannot. I bought a powerful LED light from DealExtreme for my keychain to use as a replacement as I was used to the HD2 LED flashlight
There are a few apps for the HTC 7 Mozart. But they only make the screen bright! In my oppinion thats pretty useless...
Yeah, Xenons cant light up permanently. They physically just cant.
And using its display as flashlight sucks.
I read that the flash can only be used for short periods of time as its an Xenon bulb and will burn out if used for to long.This would also explain why know one has made an app for this. The screen light apps are no good but thats not the fault of the app makers as if they could do some thing with the flash im sure they would do. Its almost as important to have a touch as it is a alarm these days and we have all kinda come to expect it. Hope this helps.
The xenon flash is driven by a flyback converter (in the same manner as a capacitor, sort of) running voltage of around 200 - 300v, as the naked battery power isn't capable on it's own... The reason it can't be used as a flashlight is basically due to the converters recovery rate...

true, its kinda important, all i ever read was how awesome the xenon flash is but never a word about its disadvantages untill i got one. well i can live without light, always got a lighter, or consantly take pictures like in some horror movie for light
then i read this nice mozart review and about the camera
http://www.missuall.com/htc-mozart-2/
The xenon flash on the Mozart is a bit of a joke. First of all it is too weak and is only usable in low light at a short distance. Attempts at using it as a fill flash with day light were met with spectacular failure. Apart from being weak, there are also three more reasons why the flash fails to perform adequately. First, there is no focus assist that would help the camera focus in pitch darkness, which means your images would come out of focus. Surprisingly though, it worked quite well in low-light.
Secondly, the camera cannot judge the distance of the subject from the camera and modulate the intensity of the flash. Objects that are closer often get washed out when shot using the flash. Lastly, Windows Phone 7 is not optimized for a xenon flash but an LED flash, which means it uses a slower shutter speed, which does not work well with a xenon flash.
Since the shutter is open longer than the duration that the flash is active, the camera is unable to freeze the action the way you are used to seeing on other xenon flash enabled cameras. This is similar to the slow synchro mode that some cameras have where the shutter speed is reduced to allow more light in, except on the Mozart, that’s the only option you have.
We also had issues with the accelerometer on the phone, which annoyingly recorded the orientation of the images incorrectly. Even when we were holding the phone perfectly horizontal it would save the images in portrait mode, upside down. Because of this, we always had to make sure the camera is perfectly straight before taking an important shot, lest we took our pictures upside down.

sounds like you got some internal knowlege about, so is it possible to flash with the xenon more then one time ? how long is the recharge time, how many times can you flash in lets say 10 sec? if u cant make it always on, try to make it flash 24 times a sec i kinda think it wont be possible, but then cant we have multi-shot pictures? i wish i could view in future

xenon lights use a ballast to constantly supply the required power demands of the light, vehicles have an inexhaustable power supply for this process...

The phone flyback converters are produced pretty much with two goals in mind:
1. be small enough to fit into the case...
2. supply the demands of a low-tech, low demand camera...
I think even if you could overcome the dependance of the flash to recover only in line with the frame rate of the camera, the battery would not be sufficient to run it as a torch/flashlight for long...

This is one reason I am strongly considering the cheaper Trophy over the Mozart. The Mozart has a better build but if you plan on doing anything involving flashlight capabilities then you will be better off with a Trophy.
You could buy an external keychain light but to hold that and keep the phone steady will be a task.
Looks like HTC improved some things with the camera but my major complaint is still there. Even with every possible enhancement and option (including image review) turned off, there is still a 0.5 to 1.0 second lag when taking a picture in bright lighting even after everything is already focused with a half press of the shutter. I think it is improved a little, but still a far cry from what it should be. C'mon HTC: if a weak iPhone can take a picture instantly, surely you can do better than this!
Mike
I don't seem to have this shutter lag. The phone snaps the picture pretty instantly after I press the button.
Yeah, I'd say do a full wipe & reflash. 0 shutter lag here. I can't even get the image to speed blur while in motion.
This is with the latest 2.3.4 update.

Are you using the dedicated camera/shutter button? Autofocus is the only thing "auto" that I have enabled. Are you rooted with revolutionary?

For my fastest shots, I use the onscreen button, the camera button has a delay. Auto focus is off.
Yes, rooted with Revolutionary & using Haus' Stock Deodexed 2.08.651.2.
Just updated my wife's phone via the OTA. Hers has never been rooted and will likely never be rooted so I just took the OTA. Her's is exactly like mine. There's at least a half second delay on every shot. I've tried the dedicated camera button and the on screen button. Regardless of the settings or the button pressed, the camera doesn't take the picture until about a half second after you press the button.
Edit: I've never seen one of these phones not have horrendous shutter lag so if you think you have close to no lag, could you please post a short video showing this? I simply can't believe it until I see it.
Mike
I don't have another camera sorry. Sold it back when I had my EVO 4G.
I'm surprised you have this problem.
Try turning up the Exposure & ISO to 800 as well. This also speeds up the shutter on cameras. Will it be instant, I'm not sure but it'll definitely be faster.
Let me know if that works.

On a side note regarding the camera, what happened to the shutter sound on/off option? Now it's on by default and hitting menu in the camera app doesn't show it, am I crazy or is it gone?

Nothing changes it. Already tried ISO 800, shooting in direct sunlight, and every other trick I could think of. Minimum shutter lag is about a half second. Only thing I can figure is that some people call a half second "instant". It's far from it. Went to the Rays game tonight. Indoor lighting was bright as daylight: no flash needed. All pics were good at least and not blurry due to the fast shutter. But between my rooted Evo 3D and my wife's totally stock one, we missed almost every shot even when taking casual shots. And when you hand someone the camera to take a group shot, they press the shutter halfway to focus and then press the button the rest of the way and it NEVER works. Everyone always starts putting the camera down and the actual picture is taken after their hands are dropping because they've already pressed the button and nothing happened until a half second later. Again, this is with all auto stuff turned off, flash off, auto focus off, etc. Unless you are taking a picture of a rock or something else that isn't ever going to move, this camera is totally useless.
Mike
Have you tried wiping the SD card? Or used something other than the stock one?

No wipey wipey, but... my wife and I both use a SanDisk 32MB and my friend and his wife use the stock SD card. No difference. Half second delay on every shot, occasionally longer. I wouldn't think the SD card or it's speed would come into play for actually taking the shot: only afterward in storing it.

Hello, samsung disabled some options in camera in most of the shooting mode or scenes,I searched pretty much everywhere and I couldn`t find some useful information.Is really annoying that they did.For example,in a low light situation if I use the flash, 2-3 m in front of the camera will look very good but everything else will look bad, if I use the low light shooting mode, everything will look good but if I would use low light shooting mode + flash, 2-3 m in front of the camera will look very good and everywhere else will look good(perfect).Also the burst mode is pretty usefulness in good light situations as you would have to be drunk to take a blured picture but with the low light shooting mode where is very likely to get a shaky picture would be great to take at least 2-3 photos fast(even if not so fast as in normal mode) so you could be sure that you have at least 1 good picture.The examples can go on and I don`t think that I`m asking for something impossible.Did someone modded the camera app as stated above or is there any possibilty in the near future to see some of those useful options?Thank you in advance.
so not a single chance to accomplish what I want?
nobody can understand what you mean.
Wall of text is horrible
somebody on XDA posted a guide on enabling the option to switch the camera shutter sound on/off by editing the feature.xml file under /system/app/
may be you need to try something similar
but be very careful when you edit such files.

I mean that if you choose from shooting mode the "low light" or HDR or a lof of options, flash is AUTOMATICALLY disabled or you can't use the burst shoot with low light option enabled or HDR, that`s what I`m talking about.Is it possible to trick the camera software to be able to use all the options along?
You need to search and read the various camera mods and decide .

There is a reason why these options can't be used with each other.
1. low light mode is supposed to take into account that there is very little light. If you turn the flash on with low light mode then you're essentially not using low light mode anymore because flash provides loads of light.
2. HDR mode takes 2 shots (3 on some devices) with different exposures and then combines the 2. If flash is involved the 2 shots will pretty much look the same and will therefore mean HDR is useless.
3. Burst shoot takes loads of photos simultaneously and if flash is enabled the first shot will usually be taken with flash. The device simply cannot handle the flash being used up to 20 times one after another.
If there is software out there to "trick" the camera into being able to do what you describe, it won't make a positive difference to your photos. It's general photography and the way cameras and their features work that make what you want to happen, a bad idea!

1 if you've ever played with light settings on a dslr, you'd know cranking up ISO, low shutter speed, exposure, etc will give you such a high exposure you can't even make the picture out.. all you see is a white light.. I feel this is what would happen.. its like shining a flashlight on something during night vision, all you see is a huge white spot.. does that make sense?
its not a software limitation its just the way modern lens work.
2 agreed
3 the flash can stobe 20 or so times a second, any 'flashlight' app will show you this.. you could also leave the flash simply on..
the best workaround ffor this is use 1080p video mode with flash, it takes 30 frames (shots) a second, and while watching the video there's a camera button on screen in the stock video player. best workaround.
and yea mods will come

Yeah I agree I guess what I was trying to say is it would render low light mode useless. It would be one of those options that produces shockingly bad photos.
I forgot about the strobe, although I can't imagine this being a feature. I forgot that these "flashes" are just LEDs and not the traditional flash you get with an SLR.
The 1080p video mode is a great workaround suggestion. I hope saddameu can get something from this information.

I hope English is not your first language
That being said you are probably asking for slow-sync flash - as far as I know the S3 does not have that feature yet.
you have some good points but you took the worst combinations ever.
How can you say that is not good to take a pictures with low light enabled + flash?We are not talking about a dslr flash.If you take a picture of someone being 3-4 m away in low light conditions with flash ON it would be a better picture than taking it only with low light mode or only with flash,think about it, it will just make the person look better as the flash is not that strong to make the subject look too bright.
That is one good combination, another one could be using the burst shot with low light enabled to be sure that you take at least 1 good picture as you have to be very steady even if the burst shot would be slower in low light mode than a normal picture.I could probably take only 1 good picture in low light mode knowing the phone but if you give the phone to a friend,for example, the picture will look like it was taken from a drunk men.
Could you provide me some links with some good camera mods as I only found only hyperx`s mod.
And no, english is not my native language , I learned it pretty much by myself as in school I learned english for only 2 years but the first post was made being in rush.
Thank you,
I used my flash for the first time today I believe since I've had the phone on day one. Seems that there is some lag when using flash? Pictures take about 4 seconds to snap? This normal? Without flash they're much quicker. Thank you

I took a picture with flash on. From the time I tap the shutter icon to flash turning on with focusing and taking the picture, it takes around 3-4 seconds to snap a picture. This is normal as the flash has to be turned on and for the camera to focus. Without flash, it should always be quicker since there isn't a need for the flash, so the camera just focuses and snaps the picture.
