Should you use the flash on your phone?
The flash tool on most camera phones are not really good quality to use as we do a traditional flash on professional cameras. Using the flash inside to light up a subject often results in harsh shadows that are typically not very flattering.
That being said, you can still use the flash to create interesting photos.
If you use the flash outside in bright sunlight it can actually minimize and soften shadows and accentuate your subject. It can also brighten the colors and create a more interesting photo in low light.
Experiment with your flash outside. Try taking a photo without flash and then with flash and notice the difference the flash makes.
