I don't know if you guys know what is an HDR Picture is, but it is a very nice picture, even the iPhone 4 have it on their phone and they only have 1 camera on the device.
HDR is capable by taking images in diferent exposures and then combine it.
HDR video is capable by using two diferent cameras at the same time using the same as above.
Now that this device, the EVO 3D, is capable of doing 3D imaging and video, it will be nice of doing HDR too.
I have a feeling that it will be capable if you program both cameras take diferent exposures at the same time and then combine the photo/video for an HDR to come out.
What do you guys think?
Anyone knows something about it?
It better be...

I'd be interested in hearing how you could do HDR using both cameras since they're both seeing two different perspectives. The cameras need to see the exact same thing, or it would look terrible. Current real-world examples of capturing HDR video with 2 cameras is done using a beam splitter, which you would not be able to use with the EVO 3D since you can't correctly aim each camera at the beam splitter.
I was kinda hoping you could take 3D images, and then view each 2D image separately... In regards to doing pure 2D photography, I'd love to see HDR as well, and even multiple focal points... imagine a video being recorded with a close focus, and an infinite focus, that you can use software to pan between on-the-fly, (and after-the-fact.) I think that would be awesome.
I would be surprised if the iphone4 can do HDR very well, honestly. I just purchased a Canon S95 and without a tripod it is nearly impossible. You get all sorts of ghosting.
What would you like to see/think would be cool/only possible with the Evo 3D?
1. Dual focus images: Not sure how well this would work or how well the effect would even be perceived, but independently focus each camera when taking a 2D image (obviously requires someone to figure out how to use both cameras in 2D mode). Possibly result in a easy Tilt Shift photo.
2. 10mp image: Doubt this one is even possible really, but stitching an image from each camera together.

#2 won't work.
5mp+5mp doesn't = 10mp
10mp would be like taking the first 5mp shot and attaching the 2nd 5mp shot by a corner to one of the corners of the first shot.

Assuming the boxes with the 1's in them are 5mp each, a 10mp box would be made by making lines enclosing the 2 other boxes - where the X's are.
With the 2x5mp cameras, you'd only have 1/2 the data necessary to create a 10mp picture.
Technical talk aside...
I think it would be cool to invert the 3-d...
To take a picture of someone's head and "pop it inside out" so that their nose was the furthest point AWAY from you, rather than the closest.
I don't know if this would be as simple as swapping the two images or not - so the right displays on the left and the left displays on the right.
Nothing like playing with someone's mind by inverting the way they think the world is and showing it to them =D
Kalah, 5mp+5mp does indeed equal 10mp. Your way of thinking is a little skewed though. The pictures would come up essentially the same way the 3d pictures will be displayed on the phone normally (ignore the - signs, they are just for formatting since the site will delete extra spaces):
111111-222222- 121212121212
111111-222222- 121212121212
111111+222222=121212121212
111111-222222- 121212121212
111111-222222- 121212121212
The picture doesn't show a larger area, just a higher pixel density. The problem is this will only work for distant photos as they are taken from just slightly different angles.

Alright... Kindof.
You can get 10mp across, but your vertical resolution wouldn't increase. You'd get some really wide pictures.
To double the size of a photo, you have to quadruple the pixels... Not double them.
I'd love to see some great high quality 3D Augmented Reality apps that incorporate 3D. I'm sure there would be good money interactive 3D AR. I know it's cheesy and all, but those little pet games are very popular (personally not a fan). One thing that I would find absolutely fantastic is an app that allows you to draw or create cool 3D shapes in AR. When you close out of the app, all your drawings save and when you open it again you can continue creating awesome stuff and building an alternate digital reality splattered with your creativity. And it would be vital to add in a feature so you can add friends so you can share your world with them.

1) both images are offset as they are taken from different points, wouldn't work
2) again, different angles of the same image, wouldn't work

turn the phone upside down
or, open the mpo file in something like "stereophoto maker" (freeware), press "x" (swaps images round) and save the new mpo file back to the phone. (am sure there will be an app to do this eventually)

Again, you don't really understand what "megapixels" means. It is already width x height in the picture. Example: 1000 px x 1000 px = 1,000,000 px or 1MP
If you double one dimension, you double the MP of a photo. I didn't say you made it "twice as big." Yes, I agree that when people say twice as big they usually mean twice the height and twice the width, which is really 4x as big.
on to a different camera idea i just thought about.....
you know when you try to take a picture inside of a moving subject and it always blurs due to lights and ****. wonder if you could make an app that fires the cameras a split second from each other and you can choose one of the better pics

You could also do something like this (ignore "-" sign):
11111 - 22222 - 1*1*1*1*1*
11111 - 22222 - *2*2*2*2*2
11111 + 22222 = 1*1*1*1*1* -where each "*" is a virtual pixel value, which is
11111 - 22222 - *2*2*2*2*2 -approximated by taking some sort of average
11111 - 22222 - 1*1*1*1*1* -between the neighboring (left right bottom)
---------------- *2*2*2*2*2 -top) actual pixel values.
---------------- 1*1*1*1*1*
---------------- *2*2*2*2*2
---------------- 1*1*1*1*1*
---------------- *2*2*2*2*2
simplest approximation would be * = (right + left +top + bottom)/4.
Using two camera for 2d shoot can have only benefit in focus and sharpness, because 80% of picture is same on bouth cameras
The 3D is nice and all, but the dual camera seems like it ought to have real potential:
1) HDR (High Dynamic Range) photos
2) Accurate? distance measuring
3) 3D model generation
4) Facial security for lock screen - 3D based, so can't be faked with a photo
5) "Corrected" 2D photos - use the differences between dual photos to filter out artifacts? Better low light photos / night vision?
6) Action shooting (alternate cameras for faster snap shotting?)
7) "Hand" lock screen? (take a 3D photo of your hand, to unlock your phone?)
Just throwing stuff out there I haven't a clue on how to actually create any of those, or even if they're possible.

Try fast burst camera from the market. Doesn't use both camera's but takes pictures quite fast.
New idea?
i thought creating 3D icons... and use the 3D cam. to create a wallpaper of the image the camera see in 3D in combination i think that looks cool.

I would like to have some image effects on the 3D pictures... kinda like HDR and Vintage or Black and white 3D pics.
3D Video Chat!
We already have 3D video recording so something like live video chat does not seem like too much of a leap. Most video chat programs don't support the front camera of the Evo4g let alone the Evo3D. Having a program that specifically targets the Evo3D for 3D video chat would be an amazing feature to compliment this awesome phone.
Cheers!

What video chat apps don't support the 3D's front camera? Yahoo, Tango, Fring, Skype, and Qik all do, that only leaves Oovoo. Plus the front camera won't do 3D, it wouldn't be video chat, you could stream live in 3D though.

A camera app to create extended dynamic range image using the two camera sensors. Similar to what HDR does by creating 3 images: underexposed, normal and overexposed, but instead two images: slightly underexposed and slightly overexposed. The advantage would be that the two images will be taken at the same time thus minimizing the delay typically required for HDR where the three images are taken one by one.
What do you think? Any suggestions?
disadvantage: photos from different angles so can't be mixed so it wouldn't work
if it did work then 3D wouldn't work

Correct me if i'm wrong but I dont think that HDR capturing requires precision in position when taking subsequent images. I know that on original EVO the HDR images come out pretty good even when the capturing position of subsequent images is displaced by a small amount.
Some idea: it can be used for capturing two photos with some time delay so you can choose between two pictures
I'd love it...ANYthing to improve image quality!
Specwise the Evo 3D is having 2 5MP cameras on the back. But some websites say that the Evo 3D captures 2D images in 5MP and 3D images in 2MP (correct me if I am wrong).And in 2D mode The Evo 3D uses the upper camera to take photos and videos.So the camera below it can be 2MP instead of 5MP.Then what is the need of the having 2 5MP cameras instead of 1 5MP and the other 2MP.
I'm lost with what you said...but I will try..to many damn numbers...so the pictures will be of equal resolution since you can take 3d pictures at 5 mp.
It is in deed strange, why can't E3D take 5MP 3D pictures. Maybe there will be a firmware update in the future who knows.

I think it has to do with the processing power to "combine" those two separate pics into one 3D image. You think the camera was laggy before, try waiting for the CPU to stitch together 5MP images...
I thought the camera take 2 seperate pictures and use parallax barrier to make one preceived as depth, aslo E3D has more processing power than ordinary point and shoot 3D cameras.
From what i have read the Evo 3d takes 2 x 2mp pictures in 3D mode and links them together to get 4mp.
Regardless of that, the phone takes great pics in 2D and 3D.
Love that dedicated camera button..no more yoga finger stretches to tap on screen while trying to keep steady..
Simplest answer may be the best answer... It was designed as having to take a 2MP 3d image because of how the screen displays natively.
Why 2 5mp cams? Because they are cheap and identical, from the same manufacture and they could only use 1 cam assembly Chinese kid instead of 2 to install 2 different non alike cameras. Allows them to just buy 1 sensor in greater bulk than 2 model sensors. Hence, cheaper to produce.

but the indian GSM evo 3d have the upper 5MP and lower 2MP cam
Think of 3d as blue ray It's twice the SIze of the file. And it seems I get 5 mp in both. I miss the og EVO camera. And panorama. In windows there was a hack in the registry where we bumped up from 3.2 mp, to 8 mp in panoramic. Up too 7 stitches. Problem is we ran out of memory for more than 3 stitches. I miss those options.

There's many Roms that add panorama camera mod. And there's a ROM that claims it boost camera up to 8mp but I havnt tried it myself
Hi all,
I have installed Elixir 2, i'm not sure which one to use. On clicking on information and then on the device tab, one of my camera's says it has a resolution of 2560x1920 focus length 3.49mm and the other is 3840x1080 focus length 3.49mm, the front camera says 1280x1024 focus length 2.2mm
Can anyone tell me what this means please.

The rear upper camera can take 4.9MP images and the rear lower camera can take 4.1 MP images. Through according to me the cameras are capable of taking maximum of 5MP images but the software is made like that by HTC .
And the front can take images of 1.3MP

Else every CDMA and Every GSM phone is same (some parts might be region specific)
