…Or Bring Your Own
If the available light in your environment isn’t cutting it, you can always introduce your own. Something simple like this ring light could help add some additional ambiance to your photos, depending on how you use it. Again, it won’t be daylight. But it could result in some dramatic and cool images.
Your iPhone, of course, is also equipped with flash. That can definitely help light a scene, but it doesn’t always result in the best-looking images. To avoid overexposing a shot with the flash, you can always try putting a piece of tape or tissue paper over the actual flash bulb.
