The only lacking thing is a dedicated shutter button to take the photos with, but that's not a big problem luckily.
Here is a breakdown of all the features and settings for the camera on the Galaxy S2:
When starting the default camera app on the phone, which only takes a second or two, you'll see most of the screen is used for the actual scene you're pointing the phone's camera at, with a view settings buttons on either side. See the screen shot below:
(Oh, just so you know, taking a screen shot (see how here) while the camera is active, doesn't capture what you're seeing on the screen, it produces a black image like above as you can see)
Anyway, at the top you'll see three buttons, the first one opening up the settings screen, the second one setting the flash options and the third one is used to switch between the rear and front cameras.
At the bottom, on the left, is a thumbnail of the last picture you took, in the middle is the shutter button, and on the right is a switch button that switches between the still camera, or the video recorder.
Firstly, the settings. There are quite a lot of different settings for the camera, including stuff like the resolution, white balance, ISO, etc. Here are a few screen shots with all the settings you can set with the phone:
Starting at the top, you have "Self Shot" - this simply switches the cameras, which will allow you to take a picture of yourself (or to check your teeth).
Next you have the "Flash" button, which allows for three different settings - Flash Off, Flash On, or Auto - this is self-explanatory. The Flash button at the top of the screen also gives you the same options, which is quite convenient.
The third option is "Shooting Mode", which gives you, yup, you guessed it, a few different shooting mode to choose from, see below for the list: (I'll post some shots once I've played around with these a bit more...)
The fourth option gives you access to various "Scene Modes" - handy for stuff like Fireworks, Text, Beach shots, etc. Again, I haven't tried them all out, will post some shots as I get them:
The next option, "Exposure Value" allows you to manually set the exposure of your pictures, making them either brighter or darker...
The "Focus Mode" feature gives you three options, namely Auto Focus, Macro or Face Detection. Mine has been on Auto Focus the whole time, which works fine. When you want to focus on something specific, simply tap the screen there.
"Timer" does what is expected, putting in a delay to when the photo is taken - four options: Off, 2 Sec Delay, 5 Sec Delay and 10 Sec Delay.
The next one is "Effects", which gives you four options once again - None, Negative, Grayscale and Sepia - everyone knows these...
Then we have "Resolution", which, like with normal digital cameras, allows you to change the size of the resulting pictures you're taking. There's quite a few options:
- 8M 3264x2448
- W6.5M 3264x1968 (Wide resolution)
- 3.2M 2048x1536 (this should be fine for regular 4x6 prints...)
- W2.4M 2048x1232
- W0.4M 800x480
- 0.3M 640x480
