Flash

There are a few pros when using flash. For example, using flash adds light, freezes time, and eliminates blur. On the the contrary there are many cons when using flash. It disturbs your subject, creates ugly lighting situations, backgrounds become dark, and it creates distracting reflections.

Using flash is a good idea when you want everything lit up for artistic reasons and in bright daylight.

Flash is not a good idea when you want to capture all real colors in your photograph.

The picture I chose is better without flash because you can see all the real colors. If the flash was on, the background would be completely dark and you wouldn't be able to tell that the lights were on.
