Hi all,
I have a touch pro 2, have upgraded from a touch pro, and its an all round better phone than its older brother.
However, the Camera on my old TP is so much better than mine on my TP2. On both the stock Rom, and my Energy rom the picture is total rubbish at all resolutions that its taken from. all the images seem very grainy and distorted compared to my TP.
I have tried cleaning the lens, and that hasnt seemed to make any difference either.
Has anyone else found this?
I completely agree with you on this. I remembered I was watching a video review on this device and they noted that the severity of the camera graininess is carrier specific due to the different battery covers. The other day I took a Pic with the battery cover off just to see if their was a difference and the pic was definitely a little bit sharper.
The clear window on battery cover can severely degrade image quality if scratched or greasy. The TP2 camera takes very nice pictures set at highest resolution and with good/bright light. Not so good in dim/poor light situations.
I've seen the same thing. Detail is all mushy. It reminds me a bit of some noise reduction software set too high. Since the tiny sensor in this phone would be prone to noise (small sensors have small pixels, so their light gathering capability is boosted by amplification, adding noise), so the Tilt2/Touchpro2 may have excessive noise reduction running.
Just a thought.
Images taken w/TP2
I am surprised to hear these comments! I have had a couple people mention how good images look that I have taken (using default settings). I have the T-Mobile version TP2 and am using b16b's AthineOS 21914 (superb) and am OC'd @729mhz. I have attached a couple photos taken recently that show what my device produces with it's camera. I am not a photographer by any means, and the image quality isn't amazing compared to a high-end digital camera, however, for my everyday usage which is somewhat limited to impulsive shooting of animals or car-wrecks & bum-fights, it seems to take fairly decent pictures. I do want to also mention that I take great pains to keep my device clean and use microfibre cleansing material frequently. Also, most of my use is outdoors, I have noticed that indoor usage doesn't give great results unless there is PLENTY of light available. Lack of a flash really disappoints me, however, overall I am very satisfied with my TP2!
I've had my HTC One X for almost a year (via Orange shop here in the UK). I've only occasionally taken pictures with it, but I've recently started using the camera a lot more recently due to a new family arrival. Something I have noticed is that when people are in the photo, any reds or pinks in skin tones (faces, hands) *really* stand out quite excessively.
I have searched on this topic and I've found lots of references to an overall hue / tint problem occurring with various colours. However, this can't really be described as an overall tint. It's almost as if there's a horrible nonlinearity with the response to reds / pinks or something. If I take a picture of a face or hands, the reds in the fingertips or cheeks stand out very excessively.
I *think* it's okay with the front camera, but I'll test more to confirm that.
My camera settings were initially as default. I have tried fiddling with the various settings, and setting the saturation to -1 does help the problem a bit. But decreasing the saturation of course reduces the saturation in all colours and I can still see that the response to red is still excessive.
I haven't dealt with HTC before, but from all the horror stories I've heard I'm not sure if I want to go through the pain of returning the phone.
Two thoughts:
- Is there any way at all that the camera can be calibrated on an individual colour basis? I'm guessing this would be something only available via a custom ROM if such settings existed. Using a custom ROM could be tricky for me because this would I assume mean losing the Orange Signal Boost app, which would be a pain.
- I've noticed replacement rear-facing camera assemblies aren't too expensive on eBay. I'm an embedded electronics engineer so I'd be quite happy to disassemble the phone and fit a new camera. The real question, though, is whether the problem I have is actually within the camera itself. For all I know, some kind of factory colour calibration could exist for the cameras on the motherboard, meaning replacement of the camera would be pointless. If on the other hand the calibration is all within the camera module itself, perhaps this is worth a shot.
Any thoughts please, particularly in relation to my last point? I'm still considering obtaining a replacement rear-facing camera from eBay and swapping it over. However, before I go ahead and buy one, it would be very good if anyone out there can actually state from experience whether or not colour reproduction problems are an issue with the camera module itself. Or, to put it another way, has anyone ever replaced camera modules and found colour reproduction to be different between them?
You viewing these pictures on your phone or in PC?
If you open the picture in gallery you can edit the levels, contrast and the like.

HTC one x has bad colour reproduction, ICS was decent but JB literally stuffed everything up.

I was applying my tempered glass screen protector and after everything was done, I did a thorough check to realize that my laser sensor has hairline scratches. Will it affect the focus or performance? It's my first LG phone..
Thank you in advance!
My laser appears to have a few tiny scratches as well.
Highly doubt it will hurt anything. My g3 laser was scratched up and it seemed fine.
I was thinking of polishing the plastic and applying a film protector to get it protected. Any idea if a film would affect the focus? Thank you for the reply.

Anyone got preventive measures to prevent laser focus plastic cover from getting scratches further? Mine is quite scratched up and I'm pretty annoyed by it. I believe it won't affect the focusing speed but it's a flagship phone from LG and yet such thing happens..

The laser cover is soft, cheap plastic. Nothing you can do about it. No, it won't affect the focusing unless you put a giant gash in it that will deflect the beam. Same thing was happening on the G3. Just be careful about it.

Polish it with ABS polishing compound, then put a drop of optical hard lacuqer on it. More trouble than it's worth, IMHO.
Although LG brands it as "laser" it's nothing more than a ray of infrared shot and measured after it bounces off obstacles. So unless the emitter/receptor is REALLY weak, there will be likely no effect on the focus.
Double that with the fact that the camera uses both the "laser" and phase detection to focus, if the "laser" fails to provide focus information the phase detection will do (slower).
Think of it that way: Do you care that much about the scratches on your TV's remote infrared emitter?
Don't worry, your "laser" is fine

I don't think you really know what a laser actually is.
The whole point of the laser-assisted autofocus is to project a tightly focused, coherent beam of light shining in a single direction so that it reflects off the photo subject and nothing else. A non-laser IR diode projects light in a "cone" in all directions, which is useless for focusing the camera. It is a laser by all means, otherwise it would not work at all.
Scratching the cover might diffuse the beam slightly but only a major gash will actually impair it to the point of uselessness (since it will scatter the light in many directions).

I know very well what a laser is, thank you very much

A "perfect" laser would be actually counter-productive, for unless you have a sort of "crosshair" on your viewfinder to mark the focusing point, you may very well have your phone focus on the tree behind your beautiful significant other, just because your subject is not in the laser's line of sight.
It is actually necessary for this concept to work that the beam is conic. Here, see this image from LG's own keynote: http://androidspin.com/wp-content/uploads/2014/05/LG-G3-Laser-Autofocus.png
If it was a super-focus laser, would they represent it as a conic, albeit very narrow, beam?
They don't need a "perfect" laser emitter to work out their concept. Granted, they need a narrow beam to avoid interference and allow an accurate measure of the scene being captured but a perfect laser beam (perfectly coherent, single direction light) would just do more harm than good. This is not used for sniper rifle or whatever, it's used for focusing on a scene.
Scratches will maybe deviate a portion of the beam a little but the majority of it, unless the window is completely buffed, will still serve its purpose. I'm strongly guessing that the way it works is: Send a burst, receive reflectionS (plural because there will be more than one) and apply some algorithm that'll define the most appropriate distance to focus on, based on the collection of durations from the receiver.
So I have a question on this topic. Since its supposed to be infrared, on a remote, you cant see anything being emitted unless you look at the emitters through a camera or something. When I have my camera on my G4 on, I can see a tiny red red light shining. Can anyone else actually see the red light being emitted? Just making sure mine's not defective.

I can see it too. Very much like you can see the IR emitter of your TV remote, except it's more focused here so even more noticable. Your device's fine
More on why we can "see" infrared in certain conditions even though it's out of the visible spectrum: http://phys.org/news/2014-12-human-eye-invisible-infrared.html
You'll notice that the "laser" is pulsing rapidly, which is the required condition to trick the eye into "seeing" the beam.
So, after applying a proper camera lense protector to the phone, I finally started to play with it. And in low light I'm seeing a lot of static on certain colored furniture or items on the floor, while taking a photo. The images in low light are also quite blurry. Is this due to the lense cover or normal?
I actually took the lense cover off and the static is much less now. Kinda sucks, there does not seem to be proper protection for the lenses without losing image quality. Would a liquid glass coating do?
Folks; unsure whether it's the device, the camera app or just me, but: Is it (im)possible to shoot really "sharp" images using the M51 stock camera app or hardware? Using this in various situations, it basically seems to boil down to a _very_ limited range of focus within the image with everything outside being slightly blurred which looks quite bad especially on "natural" structures (trees / leaves). From a mere "optic" point of view it feels like the camera hardly has any depth-of-field and there seems no way to fix this. Is there...?
Thanks in advance and all the best,
Kristian
Samsung Stock Camera is very bad at sharpness/HDR, it tries as much as possible to denoise pictures, and the front image processing is even more disappointing on many devices I've tried/used.
Using Google Camera, it feels very different, as there's manual settings, you can increase/decrease sharpness, saturation, hue, AWB, ...
So the problem is not the hardware but the camera app. Depth Camera works fine on objects/persons.
Consider trying the GCam that suits you from here. I can modify sharpness as low/high as I want.

Thanks for the feedback, will give it a try then. Just wondering (after playing with one of the builds for a moment): How _do_ I actually set sharpness and the like in GCam? Compared to OpenCamera or the stock app, user interface seems even more stripped-down. Maybe though I missed something here...

Depends on the mod you are using, there's a lot of mods, each has his features, but most of them has lib patcher, allowing the modification of image processing library.
For an example, here's how you find sharpness on tigr GCam mod. It has a lot of controls. You can use xml files to load some ready-made configurations. Sometimes configuration may not be compatible with your device, then you'll need to clear app data and try another one.

Ah cool, wasn't aware of that. Will test-drive some of these and see how they do. Thanks bunches for pointing me there.

Anytime, mate.
Replying to myself as recommendation / hint to future readers: All my fault. Period.
Longer answer: When ordering the M51, I applied a screen protector glass - to both the main display and the camera cut-out, in order to protect the camera when having the phone in my pocket. After spending quite some time playing around with this, I learnt that apparently the screen protector placed in front of the camera lens causes a drastic loss of quality (and, thinking a few moments longer about physics and refraction of light in different media, this is pretty obvious).
So: Without this thing on my lenses, quality is ages better. Don't use screen protectors in front of your M51 camera.

Uh .. never thought about this, because I thought it was obvious since 2014 or something that full screen protectors do cause problems with phone sensors, and front camera.
I couldn't find a screen protector with camera cutout for my A70, so I had to crack it manually.
