iPhone filters are the most commonly used of the iPhone camera effects. There are a number of filters built into your iPhone camera. You can make subtle changes to your image before you even take the picture.
get started, launch the Camera app. You’ll see three overlapping white circles on your screen. Tap on them to access a number of “looks” you can apply to your image before you shoot. The circles turn red, green, and blue when one of the filters is activated.
You have nine choices that will change the mood of the image. Aside from the obvious Original appearance, you can make your image more vivid, more dramatic, or remove the color altogether with Mono, Silvertone, or Noir.
Ideally, you should shoot without any applied filter. Then, if you want to use one of these filters later, you can do that. However, even if you do shoot with a filter applied, it’s good to know that you can remove the filter afterward, or switch to a different filter.
Always remember to use filters sparingly. Concentrate on taking good pictures first, then apply a filter to see if it provides the subtle enhancement or mood you envisioned.
