Exploring Manual Exposure
With manual exposure, Apple allows you to control how light and dark your images are, thereby preventing washed out nature scenes or underexposed portraits at sunset.
Controlling exposure is simple. Just tap your desired focal point and a vertical line with a sun will appear alongside your focus box. If the exposure is already set to your liking, great! If not, simply swipe up to lighten your image or down to darken it. If you want to quickly revert back to the automatic settings, just tap on the screen and it will refocus and automatically expose the image once again. Using the Self-Timer
Thanks to the self-timer icon located prominently at the top of your screen in the Camera app, it's easy to capture self-portraits or join in on group pictures.
To start taking advantage of this feature, simply tap the selftimer icon in the Camera app. You'll be able to choose between a 3-second timer or a 10-second one. Once you select your countdown time, tap the shutter release and wait for the countdown to finish (your iPhone camera's flash will blink as the timer counts down). This should allow you time to pose for the shot or get in the frame with the rest of your group.
AE/AF Lock lets you lock customized camera's settings in order to maintain your chosen exposure and sharpness. This prevents you from having to refocus in between each shot and allows you to move your camera without losing your settings. This is great for taking panoramic photos, since consistency of exposure as you move the camera is important.
To set AE/AF Lock, all you have to do is touch and hold your preferred area of focus until the focus square flashes. The AE/AF Lock icon will then appear at the top of your screen. Turn off AE/AF Lock by tapping elsewhere on the screen. Cropping Photos
To crop images, launch the Photos app and tap Edit in the top right corner of the image you're viewing. Select the crop/rotate icon at the bottom and drag the cropping handles at the corners of your photo. Once you adjust your image as desired, just tap and hold your picture and move it around until you decide which parts you want in your cropped area.
If you have a particular ratio you'd like to adhere to, there's also an aspect ratio tool in the lower right corner that gives you a variety of options. Want to get your photos Instagram ready? Just pick the Square ratio! To undo changes, tap Reset.
