Presets have been a long time standard in digital cameras because they do come in handy a lot of the time.
The problem usually is that presets are seen as a crutch or an easy way out of taking good professional pictures, but in reality they could help you do great things and help you even mix it up a little if you like experimenting.
To change this mind set would really help you with your digital photography lighting problems.
You just need to remember that help does not mean your weak or bad at taking pictures.
Now there are many different cameras and they all tend to come with different features.
I can not cover each and every preset there is but i will quickly go over a couple standard ones, and most presets come with self explanatory names or titles to them so you should not need much help finding out what they do.
Night time presets are probably the most significant presets you can use.
They allow you to take pictures in a lower lighting situation allowing you more freedom from having to need a good digital photography lighting setup.
Motion presets are other pretty useful presets that really improve a picture taking session when used right.
These setting allow you to snap moving objects without leaving a blur or poor quality shot.
You could see how in certain situations these two preset settings could really help with your digital photography lighting problems.
Though these are only two of the more common presets, and there are many more which can come in handy with some of the digital photography lighting problems you may have.
You should go out there and try some experimentation with the presets your camera may come with and see if they can help you out.
