Mobile phone cameras are good - for many applications they are better than the early "pro" digital cameras.
...but I have several cameras, and when I was taking pictures of the "tunnel path" I needed more depth of field - so I needed a (semi) automatic camera so that I could set the aperture. Mobile phone cameras are very small format - so they have good depth of field - but they cannot perform miracles.
The "Camera +" app on my phone does have a "full manual" option - but I cannot see any way to get it to use the 2* lens... yes I have found it!
You can tell it what to focus on and where to take the light meter reading, and set iso, etc.
I have just upgraded to Photo +2... which gives me editing options I do not need - and lets me tell Siri to open the camera - and take pictures.
What does your phone camera do for you?
Could someone set up a 20th century country somewhere?
