Tilt2 camera?....

Ok, this camera states its 3.2 megapixels. But the picture quality is worse than the one from my old phone which had only 2 megapixels. Do I need to change the settings or anything?

Megapixels have nothing to do with quality, only size. Make sure you have the largest resolution picked and that it is set to SuperFine. Still, the camera on the TP2 is only so-so.

Wow thats stupid. I don't like the camera at all.

Picture quality also depends on the camera lenses used. HTC doesn't really use great lenses.
Sony Ericsson (I had the SE C702 CyberShot phone before) uses very-high-quality camera lenses, and the pictures it produced were great!

Well, if you have a 8MP camera vs. a 3.2MP camera taking the same exact photo, and you were to print a 3x5" photo from each, the 8MP should still give you better quality than the 3.2MP. The 8MP camera is able to produce 8 mil. pixels whereas the 3.2MP camera can only produce 3.2 mil. pixels. If you were to print the 3x5" photo, the more pixels, the clearer the image.

Again, that's not a quality issue, per se. Anytime you increase the size of a photo without increasing the number of pixels used to display it, the pic will suffer because things like compression artifacts and aliasing will be more pronounced and visible. Not that these things aren't present in both the 3mp and the 8mp images, they will just be more noticeable in the 3mp image that is displayed at the same size as the 8mp image. That's the real value of more megapixels, the ability to increase print or display size without the ill effects. But that has little to do with quality.
I've been a pro photog for the past 18 years and shooting digitally for magazines since 1997. I started with a sub-1mp camera back then and the quality was fine, but the low pixel count limited our ability to use digital pics for more than just 1/4 page shots or smaller. By the time we got to 4mp cameras we were using them for full page spreads without issue. An 8mp camera can now yield a decent two-page spread. Still, the quality of pics hasn't been increased with more megapixels, only our ability to display them at larger print sizes.
It's easy to confuse megapixels with quality and manufacturers share much of the blame for convincing consumers that more mp=better quality with their sales shtick, but when you understand that quality is not necessarily tied to size, you realize that application is the main factor. For instance a 2mp camera can shoot very high quality 4X6 photos, but blowing those same pics up to 8X10 will reveal the weakness in megapixels, not quality. At the optimum size for a particular mp format, more mp does not yield higher quality, only higher storage and processing needs. It will give you more flexibility in cropping if your skills with the camera are lacking, and more format choices when printing, but not higher quality.

So how would I get the best quality out of my camera?

Have you installed the cab that gives you more camera settings? It gives you a SuperFine setting unavailable on the stock setup. Do a search for it. Also, make sure the lens is clean. Handling the phone often causes fingerprints and smudges on the lens that reduce photo quality.

Thank you so much, do you have a link or know the name of it?

The one I found is ExtraCameraModes.cab.
Here ya go.

Ok, it didn't change anything haha. But thanks anyways

I thought it comes with Super Fine by default. Anyway, I've always had to play around with the light settings the get the color I wanted. I set the ISO at 200. And lighting also takes a toll on the quality of the picture.
Anyway, the camera sucks. i wish they had a button to turn off auto focusing when i need to take quick shots lol

Cameras on cell phones are more of a convenience than a sophisticated capture device. While some actually take fairly good photos, I wouldn't expect too much from any of them. They certainly aren't designed to replace a good point-and-shoot.

OK, well thanks for the help everyone!

arc camera jpeg compression level

is there any way to tweak the photo quality? i think there is too much compression by default. i take photos using 6mp widescreen mode.

Yeah it's a known problem, i made a test i took the same picture with 6M on, and another with 2M, the quality is almost the same. Hope they will fix the problem with the update soon

if i don't root, are there any marketplace cameras (free or paid) that will let me take pictures and I can set the jpeg compression level?

Even if it's rooted, I haven't come across a method/app where you could change the compression ratio. I hope I was wrong.
Sent from my LT15i using XDA App

Also looking for a way to take better advantage of the camera on this phone. the quality is terrible due to compress

Any Update to this?
Really annoying bug.

I don't sure that the real problem is jpeg compression, it's too high but in macro shots the image are very detailed and beautiful at 100% crop. In the photos taken with infinite focus (landascape for example) they are very orrible at 100% crop. Is possible that the problem is the too long esposure time?
I compared the exposure time of the arc's and a digital camera's photos. Taken the same object with the same conditions etc, the exposure time of the camera's photos are much lower than arc's photos.
What do you think about?

In any phone camera you have a much smaller lens aperture and a smaller sensor size than in even the cheapest and nastiest of dedicated digital cameras.
Thus to get the same image brightness in the same conditions you will either have to amplify the signal (which will increase noise) or have a longer exposure time. Ye cannae break the laws of physics, captain.
Having said that, i couldn't say whether the long exposure time is the cause of the issue or not.

As far as I read, Camera Advance (https://market.android.com/details?id=com.mnapps.cameraadvance&feature=search_result) is able to control compression. JPGs on the Neo are now more than twice as big and don't suffer as badly from compression.

Haven't checked the compression, but I do have raw picture and video samples from the latest 4.0.A.2.368 build.

OnePlus 5T: Camera Software Review

There's a constant debate between OnePlus 5T, its camera.. vs. Google Pixel 2 XL. For myself - I can't justify nearly double the price for the lower megapixel camera and subpar display.
There were also a few camera related enhancements in recent firmwares leading to 4.7.6. Also, for me there was no interest in social media crap - beautifying, etc. I also couldn't make GCam work with back camera on 4.7.6.
All of the photos were made using intentionally difficult conditions.. dim light, photo taken at an angle, etc.
Camera FV5: Creates very noisy pictures, even with optimal lighting
Better Camera - HDR: Too artificial colors with slight red shift, textures are not uniform
Better Camera - Single Shot: Textures are much better, colors are greyed out, some noise still present
Better Camera - Best mode: This seems the most optimal, least amount of blur due to lack of optical image stabilization, as this mode takes 3 shots, and selects the one with the highest focus.
Fotej Camera - HDR: Very poor, spilled ink like effect instead of slight glow
Fotej Camera - HDR off: Also very poor, lack of clarity or details, noise.
Open Camera - Using Camera 2 API, 95% JPEG quality: too much sharpen, textures are not even uneven, but grainy, with blackish dots, loss of texture details
Open Camera - Using Camera 2 API, 97% JPEG quality: same - too much sharpen, but textures are more even, grainy blackish dots are still present but a lot less
Open Camera - Using Camera 2 API, 97% JPEG quality, HDR Mode Always On: Too significant loss of details, loss of texture details
In summary, I think 5T stock camera and Better Camera with Best mode wins. 5T works a bit better with color, textures, does not abuse the image taken, while Better Camera in the Best Mode takes 3 photos, and selects least blurry one - which seems to be the only way to compensate for the lack of optical image stabilization.
Other conclusions:
- HRR still doesn't seem to work well on 3rd party camera apps
- Stock Camera HQ mode still doesn't work, blur and loss of details is significant
What are your findings?

I really don`t satisfy with the camera

Samsung Galaxy S9 Dual Aperture - f/1.5 vs f/2.4 | What's the Difference ?

We have an early camera test from PC World. After looking at the photos, I don't see major changes in Photos taken with both aperture sizes.
You can hardly say this is taken with f/1.5 and this is from f/2.4!
Both f/1.5 and f/2.4 images look good and similar in all conditions. :cyclops:

Covered here: https://forum.xda-developers.com/galaxy-s9/how-to/notice-post-questions-t3754328

f/1.5 allows more light in, so the same scene can be taken at a faster shutter speed and/or lower ISO. Faster shutter speed means the shutter is open for a shorter amount of time, so less chance of blurring due to movement of the camera while the shutter is open. Lower ISO means less gain, so less noise. Both are big benefits for low-light photography. I don't think the scenes used in those pics were the best examples of showing off f/1.5 vs f/2.4.

I have S9 it has very good Camera not great.
I think Samsung should just go to a larger Sensor.
Is this Camera any better than the 16 Megapixel from Note 4 ? Is it 5% better ?

RAW capture in Nokia Camera | My Google Camera opinion.

Recently I got my Nokia 6.1, well first thing I did was download Arnova's Google camera and Potter's Night Sight Google Camera.
Maybe it's me buy I wasn't able to find RAW capture in default camera app. Need help with this because I liked stock camera features.
as for Google camera, both cameras with Super photo settings, I noticed high amount of noise. Check photo corners
Both in night sight and HDR+ modes, so I'm sticking with stock camera, and using Gcam HDR+ only for selfies. Disappointed.

In poor light conditions, dslr-s also have noise in the final image, so you can't expect miracles from a sensor, that is as big as needle pin, compared to APS-C or FF sensors, which have way more area for gathering light. Combine that with the poorer high ISO performance, the lack of long exposure time, and the lack of variable aperture - I'm really amazed what the computational technology of GCam ports are capable of doing in low light, HANDHELD!!! Today I made some tests, and with nightmode I got results, that would require a tripod for my camera to make an image with comparable quality.
Stock camera doesn't have RAW support and RAW doesn't "eliminate" noise - on the contrary - in some situations, GCAM copes better than me in editing the noise out and preserving the detail (I do it in lightroom).
So for now, GCam with nightmode is quite a thing, given the limited hardware of every smartphone camera.

Well I am photographer myself and I understand what you said, but in my case even with ISO100 and 3 sec shutter with tripod final image has artifacts not noise. I noticed that even in daylight, somehow after phone
restart I got less of that, so possibly it was software bug.
So far I tested Footej Camera and Momento Pro Camera both of same allow saving in RAW , however they don't support long shutter speed above 1 sec.
FV-5 camera also is good, saves RAW format and also is pretty well.
As for Google Cam, I use it for selfies, they are a lot detailed, for video I recommend Cinema 4K , you get decent quality with 200mbps bitrate (sample)
And software stabilisation in that software is quite decent, make sure you shoot in 1080p for stabilisation to work.

I tested with lightroom camera, and sadly, I should agree with you, but I don't think it's a software bug. It's either the capability of the sensor (reason one for the short maximum long exposure time), or just fast overheating of the sensor (less plausible).
I've seen a comparison between pixel 3 night mode vs a7riii camera - it's amazing, and has nothing in common with the noise in 6.1. And this makes me think of a third reason - as this program is a port, it might have special algorithm for cleaning the noise of the pixel sensor, which doesn't work for ours. This theory can be checked by asking someone to take a comparable long exposure with pixel 3 in dng, with a third party program.
