Re: iPhone 5S beats 1020 in low light photography ����??
flash is a useful tool, but it is not a god's tool. Our built-in flash is terribly weak in photography terms but thanks to the manual control in our L1020 it still can be useful when used within its capabilities.
There are many tricks photographers when using flash. One of the most common, simplest and easily works on our L1020 is called
Slow Sync.
In normal automatic circumstances, using flash will usually cause your foreground subject to be highlighted, but you will lose your background. Slow Sync enables your background to be captured while using flash to illuminate or highlight your foreground subjects. Refer to my sample photos to see the difference by using Slow Sync.

As our L1020 do not have selection of flash mode available in DSLRs, to use slow sync we must manually set the shutter speed and ISO ourselves.
- First, take a no-flash photograph of the background in automatic to find out the shutter and ISO values needed for the right exposure. View the image and take note of the values the auto-exposure computer used.
- Then go into Pro Mode. Set the Shutter and ISO to the closest values used. Put flash to "ON" not "AUTO". This will force flash.
- Now with your Shutter and ISO set to the correct exposure to capture the background, and Flash forced to illuminate your foreground subject, you are ready to go.
This method of flash is useful in the following scenario. You are watching a night soccer match in a stadium with your friend sitting in front of you. If you are using full auto flash a very common result is only your friend will be exposed, but the on-going soccer match is underexposed or lost in the background due to the fast automatic shutter speed. If you turns off flash, you will be able to capture the field but your friend will be in shadows.
By using Slow Sync both the field and your friend will be exposed. A sample photo of slow sync.

Other applications / implications of slow sync
Because slow sync in dark environment requires a long shutter exposure - to let in enough light to expose the background, any moving objects and camera movement will show motion blur / trail.
The flash however, will freeze any moving objects within the
illuminated area due to the
short and powerful burst of light.
Slow Sync, together with Rear Sync, are used by photographers to capture motion, and still able to freeze and capture the subject using flash.
Despite of these, do keep in mind our flash is only so "powerful", and the illumination distance is only so "far". Subjects further away will not be reached by the flash.
To use flash to the fullest and its limitations its is good to read up on how flash works.
Now try this on iPhone 5S
