for those asking for a tutorial on good photo taking, actually there is nothing much to learn for smartphone photo taking. not that it has a lot of setting like DSLR (aperture, shutterspeed etc).
i suggest playing around with the settings eg.
scene mode, turn on outdoor visibility and auto contrast, iso settings & metering.i am no pro but i have taken basic photography classes before. terms might not be correct so corrections are welcomed.
ISO settings (useful when taking photos in lowlight)
- low ISO, less noise (better quality) but cannot capture good lowlight photos
- high ISO, more noise (low quality) but can capture better lowlight photos
I suggest : put it in auto mode. fact is, the camera knows better than you. to know the right setting for ISO, you will need to take in consideration for the aperture etc and do some calculation.
if you're taking photos in lowlight, don't bother with this setting. put the scene mode in lowlight instead. setting can go highest only to ISO800 (which is quite low if you really want to shoot in lowlight) but scene mode sometimes can go up to ISO1600
Metering (useful when your photos are too bright / too dark)
-
center weighted: camera adjusts the brightness of the whole image according to the center of the image.
you have more control over matrix mode.-
spot metering: camera adjusts the brightness of the whole image according to one spot of the image.
the whole photo will turn very dark if the spot you chose is bright. vice versa-
matrix: camera adjusts the brightness of the whole image according to the whole image.
you will almost never get an overexposed photo.I suggest : put it in matrix mode. you will definitely get a better picture end of story. unless you want to try something creative like taking photos in a very dark setting, then this comes in handy.
other than those mentioned above, a steady hand is important. no matter how good your lighting is, if the photo is blur, it's over. of course unless it is intended.
this is what my lecturer taught me and i've practiced it until now - hold your breath for a second when you press the camera button. less shaky this way.don't use
digital zoom. chances are, the photos won't turn out good.
and if possible, take photos where there is
a lot of light. do NOT use the LED flash if possible.
if you want to learn more, i suggest you take more photos and gain the experience. no tutorial beats accumulated experience.

This is very informative ...
and regarding the iso, i dun like the auto setting for iso taking low light scene, very bad... the camera tends to produce more noise ...
the phone itself set auto to central weighted, so i thought it is better... now i know which scene best use that setting... thanks
btw, i always take photo while holding my breath haha...
