[Q] Why HDR apps don't work on our phone - HTC EVO 3D

So why don't HDR apps work properly on our phones?
One manufacturer I contacted insisted that it was because the EVO 3D doesn't utilize the android api properly to adjust the exposure setting. I even confirmed this with HTC. You can try it out as follows: If you open the camera app and play with the exposure slider in the options, you'll see that instead of changing exposure, what it does is just bumps up the brightness of the image.
HOWEVER, yesterday I noticed that the exposure does change properly but not when you use the slider. Best way to try this is sitting next to a window on a sunny day. If you point the camera towards the window, the exposure auto adjusts you can see the details outside but anything inside the room still in the frame just looks dark. However, if you point the camera so it's mostly pointing inside the room, you'll notice that the exposure auto-adjusts again so you can now see details of objects inside the room but any part of the window still in the frame is now completely washed out. So..auto-adjustment of exposure works.
Now in most of the these HDR apps work by taking a picture on high, medium, and low exposure and then stitches them all together. However, the app isn't able to adjust the exposure settings properly and this is probably because it's tapping into the "exposure setting" in the camera's api...the same thing we are able to change when using the exposure slider on the camera app. As I said before though, the exposure slider is actually controlling the brightness. But I'm now certain that the camera is actually able to adjust the exposure but only does so through auto-adjustment. What's broken is the ability to set the exposure manually. How would one fix this?

where should i post this to get the attention of the devs who might know how to fix this?

The issue is it is a hard question. lol I don't have any idea. haha. I think the issue is we have two front cameras.

two rear cameras my man. There's only one in the front

Interesting... I've used a couple of hdr apps on gingerbread and they appeared to work. Although I didn't do rigorous testing. All I did was compare normal pic against hdr app and I noticed a difference. However this was last summer. Maybe something changed since then.

Oh and the stock camera app in ICS, or at least in the couple of roms I've tried, has hdr as a feature. Except it isn't true hdr I don't think. It snaps 1 pic then processes it. I didn't think there was any difference at first, but I did notice a slight improvement.
Sent from my PG86100 using XDA

There will always be slight differences between stock vs HDR pics because the HDR app usually does some post-processing however, if it's not taking 2 or more pictures that have the exposure adjusting drastically, you're not really getting the HDR effect.

Yes, I know about hdr... The processing and everything. I just hadn't tested these things like you have and sharing my experience.
Anyhow... I had also read others claim htc didn't use the app right months ago. Not sure why they messed that up. I'm going away for the weekend and might mess with this myself. If I see anything worth adding I will.

That's excellent news! Are you sure the exposure setting works properly and doesn't just change brightness? I know you probably tested it before posting but if you could do this for me and write back, i'd really appreciate it.
From inside a room from a distance, point camera towards a window. Are you able to see detail inside and outside the room by changing the exposure slider to either extreme?

I haven't had a lot of time to play but it did work. I'm a photographer and video producer so I know what to look for. My quick test however was as a passenger in a car. I pointed it to the seat where part was in bright sun and then other was in shade, plus some of the frame of the car in shade. Stepping down showed the detail in the seat in sun, increasing it showed it in the shadows.
I also tried hdr + (I think that's the right one) and each of the 3 photos was at a different exposure, granted not by much.
There is still a bug where the front camera flips the photo left/right after it's taken, however, you only seems this after reviewing the pic.
Edit: the app was hdr camera

awesome, perhaps HTC got around to fixing it in ICS. Several months ago, I actually contacted them describing to them what was wrong with the camera. After a lot of back and forth and escalating the issue internally, I was finally able to reach the team that actually works on the stuff and they confirmed the issue and said they will include a fix "in a future release" but did not make any promises. Maybe they got around to it
I'm going to have to flash a ICS rom to test this myself once I find some spare time

[Q] Adjust manually camera's shutter speed/exposure

Hi,
I have searched from all over the web app that could change camera's exposure time. I like to take good nigh photos, or anyway as good as it's possible with mobilephone camera, but like in mine HTC Desire exposure time is way too short.
I have tried many of those camera apps from market, like camera 360, but non of them can adjust shutter speed/exposure way I wanted. Say, I want a long exposure for night photo. For example I would like input exposure value to app, so that it would expose photo for 10 seconds.
So, do anyone know app to change exposure/shutter speed?
And my Desire is not rooted and I'm currently not planning to do so.
Would love to know about this, too; any ideas for this?
Sign me up for this as well.
Long exposures would be great. Would need some sort of remote shutter release or time delay ideally and a mounting system, tripod fashion.
Problem is - you'd also need a mount or tripod of some sort to hold the camera still enought to make long exposures work
I don't know about the rest of you but I can only handhold steady my DSLR down to about 1/80th of a second

I have managed 1/15 and 1/8 (the latter very rarely) handheld with my Pentax (image stabilisation built into body FTW), but yeah, you would have to use a tripod or to prop it up and have a timed shutter release for the phone. This isn't a problem as such, even just being able to specify the aperture would be welcome.
Well a mount can be anything...jumper, phone leaned against a wall. Would be awesome for cityscapes and such. Anyone found anything which indicates this is possible with a software patch? New to android and just tearing through my first rom package
Exactly, it doesn't have to be anything serious, just lean it against a beer for example.
I can't see a reason why you couldn't manually control everything, I can control ISO, metering, etc on my SGS, adding aperture and shutter shouldn't be outside the realm of possibility.
Had a look around as a noob to Android dev/roms etc. and I don't think it's possible to control the hardware to that level :/
Would love to be corrected on this, though!

Not to be too big a jerk here, but if you can only hand-hold an SLR steady, any SLR, at 1/80 or faster then I'm sorry to say that you may have a serious case of parkinson's, or are the most ADHD person who ever picked up a camera.
1/60 is recognized as the speed at which regular hand-held motion is mitigated, and unless you're actively moving the camera (or standing on top of a paint-mixer), you will not get camera-shake at that speed. Most photographers are able to hand-hold, and get a shake-free shot, down to about 1/8 on a good day.

What was the rest of the code? and did you try this on actual hardware or the emulator?
I will try to code an app for that. Plus FFC Support...
but you'll have to wait until I'm back from Japan
EDIT: It's not possible to really influence the shutter-speed or the aperture, because it is non-existent in the hardware, but there can be an interpolation of both values that are calculated from ISO settings and exposure calculation. It won't be perfect in any way, but it might be possible to do something similar... probably it is possible to gain more control via the ndk or by "cheating".
Thanks Flokey!
Does anyone knows if there is such a program?
I don't think a long shutter on todays camera phones would be useful as the sensor noise would be crazy bad.

Tip: Camera app has controllable focus

I had been disappointed the camera app didn't apparently support tap to focus. Turns out it has something similar, just hidden behind an awkward user interface.
You can slide the focus box in the middle with your finger to whatever you want to focus on.
I thought I had explored the app pretty thoroughly, but didn't find that one until I read the review of the Photon on Phonescoop.
If i am not mistaken (and usually i am) lol, I thought I was able to do that as well on my EVO 4G running MikG. I don't have my EVO with me at the moment here at work, but I'll see once i get home. Either way, good to know.
Thanks for the tip.
Edit: just checked with my sis and nope I must have imagined it doing that.
TS out
OK so whatever you move the box to center on is the point of auto focus for the photo....very cool !
now, how do we turn off the extremely annoying shutter sound?
Even with manually adjusting the focus, have you noticed that this camera is particularly bad at taking close-up photos? My Nexus One never had a blurry or out-of-focus photo, but for some reason the camera on my new Photon takes crap pictures. I've even tried the macro mode and it still looks terrible. This is at about 4 inches away from the object being photographed. I tried in various different light settings too.

I'm a professional video producer and hobby photographer. I haven't tested the Evo 3D's camera for video yet, but the problem you described is common in all auto cameras.
When a camera is automatically adjusting exposure, shutter, iso, etc. it adjusts for the brightest dominant subject in frame. The camera thinks you want everything perfectly exposed and is programmed not to blow out the highlights. So, what happens is it sees the bright window and thinks "ok, lets expose to that so it isn't a white blob." If you want to avoid this type of thing, lighting has to be as even as possible to the windows (which is almost always impossible) or you frame your subject without the window in the background. You also avoid this by using manual exposure settings, but I'm not sure how much control you'll have on the E3D.
What I would be weary of is the bitrate the E3D records video at. HD is only a resolution, but if it's a crappy bitrate, the video will look like crap. If you're not familiar with that, search youtube for some sample clips of videos in different bitrates. This probably can't be adjusted in the settings, but might be adjusted with some development if this is lacking. I remember when I was on my Samsung Moment which was android 2.1, that was adjusted in the build.prop but I don't know if that's the same here.
EDIT:
Some examples of what I described -
Bitrate comparrisons:http://www.youtube.com/watch?v=0xNG6gw4cxU
Some background to the above clip, this is testing the Q scale of a hacked firmware for a DSLR. The Q scale is just the piece of the firmware that controls the video compression/bitrate. The lower it is set, the higher the bitrate it uses. He starts at about a 44Mbps bitrate in the above video and moves down to about 10Mbps or lower. I'd be surprised if the E3D records even 2 or 3 Mbps. But if you jump from the beginning to about 1 min 30 sec. you can see the difference more. Watching it through, the changes are so subtle you might not notice much.
Couldn't find a video to demonstrate, but this forum post about the subject might help:

No problem. There's a lot to factor into better low-light picture. The tiny lens on mobile phones doesn't help. The new Mytouch HTC just released this summer has a back-lit sensor which lets more light hit the sensor, for example (the sensor is built backwards so the wiring is behind it - in a nut-shell). It's like a "duh" technology but JUST emerged recently. A lot of cameras compensate by adjusting the ISO (digital equivalent to film speed or sensitivity to light) but that causes more noise/fuzz to appear. You may want to try that though if you can for video, I know you can on photos. But feel free to ask me anything about video or photography and I'll do my best to respond. I don't sign in to XDA often, but I'd be glad to exchange emails or something.

I don't think they should be in the same thread because they are different issues. Perhaps they are related, but then it would be do to a hardware issue.
What's the preferred means of posting examples?
If your having problems with both stills and videos, then it is likely related. You can attach jpg files to your post. You can upload vids to YouTube and post the links here.
Here are a few example shots.
The 1st shot is with the camera settings at default. The 2nd shot has anti-shake on. The 3rd shot has auto-contrast enabled.
As you can see they are all grainy and blurry even though I'm taking an image of something that is not moving.
The light produced from an overhead halogen. However, the pictures turn out similar under standard incandescent, fluorescent, or any other non-natural lighting. Also I tried out several other settings without any improvement (e.g. setting white balance to incandescent, setting the scene to party indoor, using macro focus instead of auto, etc.).
That's sensor grain. It happens when there is insufficient light as the sensor has to work harder to expose the scene and it heats up. Also, since the scene is so dim the camera is using a slower shutter speed, which results in some camera shake that causes a less sharp photo. Can you take a pic with the flash on? Also, if you are expecting Canon-level photography from this (or any cell phone camera) expect to be disappointed more often than not.

Cool, thanks so far. I will try it with the flash on. I have taken pictures in a lot of indoor light and if anything is moving the whole image is blurry. Sometimes it looks like the air is shimmering.
Perhaps what I need to do is to use something other than auto ISO?

Nope, just like Miami_Son said, auto flash will make the difference. That or bright enough lighting. Try it during the day time.

Like I said, in low light the camera will pick a slower shutter speed, which causes camera shake and blur of anything moving. What seems well lit to the eye is different for a camera sensor. Either use flash or turn on more lights. You can try turning up the ISO, but that can also increase grain.
Record video in 720p and the autofocus issues should go away.

Close up pictures?? how?!?!

okay so ever since i got the LTE EVO iv been seeing people take AMAZING close up pictures of bugs/insects that are in FOCUS!
HOW?!?!?!?!?
Ill find a bug outside and take out my LTE evo, open up the camera app and put the macro on "close up" and i can NEVER get it to atuo focus/touch focus good enough to see that its even a bug!

It's unfair for people to immediately blame the camera, but by the same token, it's unfair for you to claim it's simply user error. There's a degree of subjectivity (not sure if that's even a word LOL) that needs to be taken into consideration when talking about camera and picture quality.
With that being said, my personal opinion is is that the camera software on this phone is certainly flawed. It's good, but it can be better in so many ways. The camera itself is very very good. Tons of potential there, but the software is holding it back.
As for my personal experience when I had this phone, it consistently takes very good outdoor shots, but was very hit or miss when it came to indoor, lowish light shots. I have 2 pictures that was able to find that illustrate my concern. I think the problem is with the AUTO settings. Manually changing settings prior to taking the shot will produce better pictures, but it's a bit impractical to expect that (EVEN from a phone). In regards to the physical camera button, maybe my phone was defective because the first step of the button did absolutely nothing. I was told it's supposed to SEEM like it does nothing, but that it's actually auto-focusing. In my experience, that wasn't the case. The auto-focus usually happens automatically (kind of like the iPhone 4S) center-weighted, unless you use tap-to-focus. Pressing the button didn't refocus anything. In fact, it didn't seem to do anything AT ALL. Again, my phone may have just been defective. Going to make sure to try this again when I get another one in my hands.
I'm adding a few pictures. The one of the boxes and of the notebook is a prime example of the kind of shots I would get when shooting AUTO in indoor and low-light conditions. As you can see, the shots are terrible. For some reason the camera is maxing the ISO (among other things) so they came out extremely grainy. They are perfectly focused, the image simply isn't optimized. The keyboard picture shows a much better shot. In this shot the camera did a better job of optimizing under AUTO settings. It also maxed the ISO, yet it still produced a good looking shot. This one had better light, as you can see.
Overall my grade of the camera was an 8/10, and only because of the software limitations. As a reference, I also give the Samsung Galaxy S II an 8/10. On that phone the camera itself isn't as good, but the software (or maybe just the capture algorithm) is significantly better when shooting in AUTO.
Just my 2 cents.

Um, no it doesn't.
Press it down half way to lock focus and exposure, not to command a focus.
The camera is constantly focusing. Half-pressing the shutter button only maintains the focus at the time it was pressed.

Your hardware button isn't defective. It's programmed to lock focus and exposure settings instead of manually focusing.
