Is there any way to fix the Razr HD camera? In its current form its seriously flawed.
For example, I record some 1080 video in front of my very bright projector screen in a pitch black room (game replays from F1 2012) and the video recording is extremely dark, greenish, and grainy. Compared to video I've taken with my SGSIII and Nexus 4 which capture video flawlessly and exactly as I see it on the big screen, the Razr is really really bad...
I've tried a few different apps, yesterday on recommendation I downloaded the Camera JB+ app but it also just seemed to make it worse (even darker and more green)..
Has anyone found a fix for the Razr HD camera? Is there a way to hack it?? I've even found that outdoor still shots vary too, some overexposed, some underexposed, even when taking several of the same shot in exactly the same light, one photo after the other....
Surely Moto can make it better, I use the video recording all the time on this phone, and its a total fail right now, so much so I'm going to sell it
Hey all,
Here's a pretty cool macro DSLR effect I discovered the other day. FINALLY a use for 4K video resolution!
All you have to do when in video mode is select 4k (3840 × 2160) and zoom in 4x. When close to a subject tap to focus as usual and you may be shocked that the image suddenly has crazy depth of field but still remains sharp.
The reason? The camera module has an aperture of f/2.2 which is great, but that's not the real clincher. 4K UHD has 8,294,400 pixels in a frame. Just to give you an idea 1080p is only 2,073,600 pixels. So basically, when you zoom in 4x, your image still looks great. No other phone camera can do this in 2013.
Big deal, SO WHAT? you may be thinking. Well the results CLEARLY speak for themselves..
Happy shooting!

Are you saying that if you record in 1080p mode and framed the shot exactly the same, that the depth of field would not be the same? I'm confused?
I understand the merits of 4K recording, but I don't see how the depth of field would be affected.
WOW! Cant believe all that comes from the small lens sensor of Note 3

I probably should have explained this better but you can't really frame the same shot in 1080p because you'd be way too close to the subject for the camera to even attempt to focus on it. 4k allows much more flexibility for macro shots.
And do you have a 4K display to see this awesomeness?
Otherwise you're just watching it at 1080p lol.

Now I'm curious how 4K video zoomed in 4x downscaled to 1080p compares to 1080p video zoomed in 4x. I wonder if Samsung is using software zooming to enlarge the video image or cropping the sensor to achieve the field of view. If it's software zoom then there's obviously going to be a loss in quality. But if it's simply cropping the sensor there should be no difference. And it fact it'd be a waste of time and memory space to shoot in 4k zoomed to 4x and then having to downscale it to 1080p afterwards. That would add unnecessary steps for editing. Also, in 1080p mode you have access to the software video stabilization while in 4k mode you don't.
it's not about the resolution lol. think putting on different DSLR lenses for your phone.
great find, OP! will be trying this soon
4k works with approx 50% more colours than normal 1080p. Even if you dont have a tv to warch it in full res, a 4k clip will look and FEEL rather different than everything else.
The clip in the above link is done with a little bit of postproduction. Indeed its impressing and there is more to be discovered.

lol, it's not about the resolution. it's kinda like being able to use different lenses for your note 3.

Cropping a sensor of say a 35mm legs by 1.6 doesn't give you a 56mm zoom perspective. You're still getting a relatively wide angle shot but simply cropped.

I understand that. However, in this instance is 1080p mode on the Note 3 simply cropping the sensor to begin with? My question in relation to the OP is if you shoot at 4K mode, zoom in a 4X, is the phone simply cropping the sensor 4x to give you a lossless zoom? Or it is using some type of software pixel binning to give you the zoomed in view? Or perhaps a combination of both.
And how does that compare to shooting in 1080p mode with the 4x zoom?
I took a few sample videos sitting at my desk and to my naked eye viewing both videos on the Note 3's screen, there is 0 difference between shooting at 4K resolution with a 4x zoom and shooting at 1080p at 4x zoom other than the file size. The field of view is identical. I'm looking to see if there's any advantage at the end of the day if I want to end up with a 1080p file as the end product. Is there any advantage to shooting the same field of view at 4K and downscaling?
The 4x zoom when shooting at 4K did not give me a distance advantage versus shooting 1080p at 4x zoom. The phone remained at the same distance as my subject when framing the shot with the same field of view. So for macro video shots, I do not appear to have any advantage when shooting at 4K.
Epic and very well done video!

I think what he's saying is that no matter of 1080p or 4k, distance and senzor pixels are the same, therefore theoretically you shouldn't necessarily have to do 4k to do such zooming. Question is: in effect does zooming in 1080p still record lossless as far as the sensor goes (13mil pixels), or zooming in 1080p only zooms into the 1080p capture (magnifies the 2mil pixels).

I just assumed that zooming in ALWAYS "magnified" the pixels so you'd naturally just get sharper detail with the 4k mode. I now understand my error with the field of view though (I tried it out myself too)
I guess the main thing to take home is the amount of detail you're getting from this phone's sensor.
I noticed something that I hope can be addressed in a future update, in regards to the camera in video mode.
Both 4K and 720P (HD) video resolutions appear to use very close to the full field of view that the sensor provides. But, I was surprised to see that when you set resolution to 1080P (FHD), the field of view is significantly cropped. I would guess ~20% reduction in FoV.
Since it would seem that in resolutions less than the full sensor provides, the camera is selectively scanning / interpolation the image, there would be some freedom in what FoV to use. GoPro does this nicely, with each video resolution having some number of user-selectable field of view options.
The camera on this phone is outstanding, so it's a shame to have a heavily cropped FoV in the most common video resolution.
I'm submitting this to HTC support. If this bugs you, please submit too!

I did a quick test with Open Camera, and the FoV stays the same in 1080. Seems to be an issue with the HTC camera app.

Yes, I mentioned this in my initial impressions of the phone after I first received it. I also do not like the narrower field of view when shooting 1080p. I don't know if this will be addressed when they add the 1080p/60 option, but I'm guessing probably not.
Hmm
Was pondering why it is only in fhd, even had idea it is for stabilisation...
But in 60 fps view is not cropped
I notice on alot of videos on youutbe on 4K 60fps.
It is like a smeary coating over the picture in movies that makes the picture look not so sharp and also artifical when watchning it on larger screen. Also when the camara moves it gets unsharp. Look at this video on a larger screen.
Look on the ground in 7:30 and you see much more details in the P20 Pro video, and also the overall sharpness. There must be some kind of possiblity to fix, because Oneplus 3/3T have sharper videos.

I read somewhere that the unsharp artificial tint(?) is becuase of that the software im the camera have problem hadnling the grayscale(?).
Also the picture in the movies are oversaturaed and dosnt feel natural, just look at this video when they compare OP6 to Iphone X(6:58 in video)

I really hope the Oneplus could fix this in an update
Or is it possible that the gcam might handle this better?
Hello, I've been an XDA lurker for a while, starting with my Galaxy S4. I just recently got a OnePlus 6, and love it so far, but this one problem is kind of irritating me.
When using the front camera (both in the camera app when not set to 4:3, and third party apps like snapchat), the picture looks very zoomed in). I'm guessing its because any other ratio is just a cropped version of 4:3.
The only way I can think to fix this is to force a different ratio for the camera to use, but I'm not sure if that is even possible.
Anyone else have this type of problem? Help would be much appreciated.
I think its because the lense has a higher focal length... Nothing to do with ratio.
So is there any way to work around this so that the front image isn't so zoomed in?
For video? It's because of their stabilization

I mean in the pictures. Like if you're taking a selfie, the viewfinder shows the image as very zoomed in (like your face covers the image if you're a normal distance away), and the picture is taken like that.
When you shoot with 4:3 you have all the picture of the sensor. When you shoot with 16:9 or other you don't use all the sensor but it crops the image to be in that ratio. And you see the zoom. Take a picture with 4:3 and zoom with your fingers to see a picture of 16:9 shot. It's the same.
