The problem when using camera is:
At first, I set "Macro" for the scenes. The first photo captured was a macro one. Then I continued to take other photo, and the second and later ones have no longer been in "macro" mode, although I did not change the scene settings. It was likely captured in "normal" scenes.
There was a simultaneous problem with the "white balance" function. Specifically, at night I set "cloudy" for the white balance. The photo taken had a warmful color, likely normal with "cloudy". But the second and later ones were like in "incandescent" mode.
Thank you so much for any help!
Waiting for better firmware!

I'm trying to understand what makes a camera phone produce good quality pictures. Initially, I thought it was pretty much solely dependent on the camera itself: I have an HTC EVO 4G LTE and it's 8MP. I want even better picture quality so I was searching for phones that had more megapixels, since I assumed that more MP the better. But during my search, I saw more discussions centering around the camera software, and how that effects pictures, which I hadn't even known before. Can I just simply download a camera app and get better quality pictures, or will I have to get a new phone, or both?

Sort of. Megapixels are a measure of resolution, which is essentially how many mini-dots of color make up an image. One megapixel is the equivalent of 1,000,000 of those little dots, called pixels. They make up every digital screen you've ever seen. The more pixels an image has, the more detailed, and the the clearer it can be.
Now, there are some issues with large amounts of pixels in a small camera. One is that each pixel in the sensor must capture light, and the smaller they are, the longer they take to capture enough light for a well-lit, clear picture. That leads to the second main issue, which is blur. When the shutter time (amount of time that the camera sensor takes in the light that forms the picture) is long, you get a well lit, clear picture... provided the subject is stable, and your hand is too. If something moves, then the sensors see it both in it's initial - "true" - position, and every position in between where it ends up when your sensors stop taking in light. This causes blur. When the shutter time is short, blur is reduced, but pictures are darker.
So, yeah, the software you use is important. Some will use smart software to correct for blur, some will automatically brighten the image (Which reduces detail), and the best ones (IMO) let you set your own shutter time depending on what you're taking a picture of. For example, if you're watching a baseball game outside, you should set a very short shutter speed so that you minimize the amount of motion blur captured, but there should be plenty of natural light provided by the sun. If you're in a dim art gallery, you may want a longer shutter time, as you need the time for lighting, and nothing's going to be moving.

Wow, thank you for that very detailed answer Creed I understand this much better. So basically (let me know if I'm wrong here) a large number of MP won't make much of a difference if your software and settings suck? So, on average, what is a decent amount of MP? I have 8 right now on my HTC EVO 4G LTE. Can you also suggest a good camera app? Thanks very much in advance :good:
Hi guys
After doing lots of practicals in different condissions. I found some of the tricks to maximise the quality of picture captured by your smartphone.
So just follow the guide according to what condition you have.
1-- Day time(high to mid light)
Keep the iso value as low as possible.
keep flash onn.
Choose auto focus mode insted of macro mode.
Always try focusing on a light colored object insted of dark color.
Do not focus on plane objects as camera often did not resolve correctly.
if capturing an image with bright colors then you should be a litile bit far from that object or to take a closup have sone shade on that object from sun.
if inside room or in shade from sun set canera to clody mode insted of daylight.
2-- night time(high to mid light)
Keep the iso value as low as possible.
Choose auto focus mode insted of macro mode.
Always keep flash onn.
Always try focusing on a dark colored object insted of light color.
if capturing an image with light colors then you should maximise the exposure value.
if in a room with lighys onn use florosent mode.
3-- night mode(low light)
keep iso value high.
keep flash onn.
maximise the exposure value.
set camera to auto focus.
cloudy mode is perfect for your images.
do focus on object which you can see on screem in dim light.
never zoom your camera.
while closeup in dimlight keep exposure not too high.
4-- images of more than 6meter distance
these images can be clicked only in day time.
keep iso value not too low.
keep exposure maximum.
keep focus to infinity by tapping on any far off object.
set camera to daylight mode.
keep flash onn.
keeping flash onn reduces the shutter closing time. and this allow to get a sharp image without any shakes.
setting iso value to low reduces noice in images but it also reduces the brightness considrable.
exposure is the brightness and contrast of image.
and mode like daylight.cloudy and floresent are type of filters to get natural color in any situation of lights.
i hope this helped a lot.
many of you i think need this. hit thanks if it helped.
peace

I find the when I shoot in Superior Auto in low-light, many times there appear a violet / bluish haze on the left side (no flash fired). I find that switching to Night Portrait or Night Mode is too much of a hassle, ESPECIALLY when the conditions constantly change like going to a different place that's brightly lit or going inside a restaurant. Also, these modes tend to have motion blur.
Now I'm thinking of Manual Mode but basically got the same results as Superior Auto (probably. I'm just not good at tinkering with the settings).
Any tips?
Thanks!

In night conditions only use switching ISO settings,exposure and white balance.
For examle,when it has blueish scene turn the white change white balance to one in the midle if the list,and you will got more reallity look of scene you photographing.Also ISO settings dont go over 800 and you can sometimes change exposure ti minus to get a less noise.Try with those settings and you can get ok images.

Here a a few tips on controlling the stock camera app in auto-mode that you may or not be aware off.
Just thought it may be of help to other owners.
We know we can control pretty much all aspects of camera in manual mode (focus, metering, ISO, WB, etc).
However, on the Xperia 5 the manual mode generates more noise in the images than the auto-mode, especially noisy in non-HDR mode whith dark environments on the photo background areas, edges and faces.
So I end up using mostly the auto-mode except to force HDR or for long-exposure shots.
In auto-mode, there are quite a few things I found frustrating compared to manual mode, but for which there are solutions:
Control scene detection: sometimes you don't want auto Backlight (HDR), Document, Food, etc. >> To temporarily disable scene detection in auto-mode, simply click on the sun icon on the left. When the icon is blue all photos are taken in standard mode: no HDR or special color processing.
1st Edit: Condition: you must use tap to focus. (If you just focus with the shutter software button, the hardware button or object tracking, scene detection won't disengage unless you actually change brightness or tint.)
Control focus: eye focus works quite well for faces. To focus on other objects, auto-mode has 3 options:
1. Auto-focus (the large green rectangle that appears when you click on shutter soft or hardware button): This tries to guess what the subject is and often leads to unpredictable results.
2. Object tracking (yellow rectangle): This is useful for moving objects. I don't use it for anything else because it typically detects and focuses on the outer edges of objects instead of the center of objects, making for blurred subjects. Also it works really bad for very small objects or when it's darker.
3. Tap to focus (blue circle): This lets you choose precisely the focus point. Much better focus results in general than method 1 or 2 above.
Control exposure: Auto-exposure is pretty good if you just point and shoot. But if you use the precise tap to focus method in auto-mode, light metering is measured on the point you clicked, and you also loose scene detection and HDR, so that's not often what you want, unless you want your black cat to turn white on the photo ! The problem is that in auto-mode there is no option in settings "Touch to adjust: Focus only" (option only available in manual mode). ...Well in fact there is a way: enable "Touch capture" in camera settings. This in fact lets you tap on screen to focus (and shoot), while still doing light-metering on the whole scene and keeping scene detection ON.
1st Edit: When touch capture is ON, tapping on screen sometimes fails to focus because the picture is taken before the camera has time to focus, especially in low light. In this case you have to take the picture twice or use the timer so it has time to focus. Well this pretty much makes this "tip" useless !
2nd Edit: Sometimes the camera fails to focus if there no contrast on the clicked zone, but touch capture is not the cause. Try to tap on a zone with more contrast to improve focus success.
So in summary here is how I set for most pictures:
1. Use auto-mode (better noise-reduction than manual mode)
2. Disable object tracking (enables the more precise tap to focus).
3. Enable Touch capture (preserve HDR, multi-metering and scene detection with tap to focus. 1st Edit: when it actually manages to focus before picture is taken, basically only in good light it seems.).
In some special situations, I adjust the following:
4. Click on sun icon, 1st Edit: then tap to focus (when I want to disable scene detection / HDR)
5. Use the lamp flash (only for macro shots in very dark condition to get usable ISO/speed)
6. Use the flash (only when necessary to get usable ISO/speed or to compensate huge backlit situation)
7. Adjust brightness with slider (if I really need to tweak brightness)
All in all I find that all the above settings allow for flexible controls and good results in auto-mode.
Of course you may have a different usage and set yours completely differently.

Quite useful tips, thanks! Especially considering that camera quality appeared to be below my expectations (coming from Pixel devices, Huawei Mate 20 Pro, P30, Galaxy Note 10+). There are few complains about X5 camera system with which I can't do anything about. Firstly, quite slow camera app start up time and its overall performance compared to other devices. Secondly, focusing system is clearly inferior too. Main camera struggles to focus on objects a way too often in situations where others do it easily. Thirdly, HDR mode nearly useless (absolutely useless compared to, say, Pixel 2). Also camera has difficulties to make decent pictures in conditions different from ideal - blown out skies, crushed dark areas, overexposure problems are not something rare here. Finally, low light performance is a way below the competition. Making good pictures in low light from handheld phone is nearly impossible. Blurry mess or aqua painting effect is guaranteed. I hope that Sony will address these issues in future updates.
Hi
While making a video of close objects Whenever the system shifts to zoom lens the saturation increases and colors become over saturated.
I make videos of gems and stones. and for that purpose i bought this camera.
Especially the blue stones become too blue when i zoom in and zoom lens turns on.
Is there a way where we can select individual lens manually so that the zoom lens doesn't turn on unless I want it.
Try with turned of AI. If nothing changes after that I don't know what can you do.
When the device switching between camera modules maybe is normal to have problems with saturation. All three camera modules have different apertures and they receive a different amount of light.
The only solution that I found is by using the pro mode and setting the white balance manually when the zoom lens turns on. By doing that the camera keeps the selected saturation even when the lens gets changed.
This is what I think. Need to confirm it with different color items.
You guyz check it aswell.
I hope mate 40 doest have the same problem. Quite disappointing bug considering the price of the phone and camera quality.
