How to Adjust Light & Color of Photos on iPhone & iPad Precisely
The Photos app in iOS includes a variety of excellent built-in editing features which many iPhone and iPad users are not aware of. One particularly great Photos feature is the ability to easily adjust color and light levels of any picture on the device within the photo library.
The Color and Light adjustment tools allows fairly precise control over photographic elements like saturation, contrast, cast, exposure, highlights, shadows, brightness, black point, intensity, neutrals, tone, and grain. The end result can be a picture that looks professional and beautifully adjusted, but completed in just a few seconds and entirely on the iPhone, iPad, or iPod touch, with the built in Photos app – without having to import or edit the image into another app.
A symbolic link created at the command line allows a linked object in the file system to point to an original object in a different location. In this way, symbolic links behave much like an alias does in the Mac OS X GUI, except that the linking and reference between files or folders is done at a lower level, and thus can be pointed directly to by various applications or user purposes. This can be useful in many situations for advanced Mac users, from providing easier access to a particular location, to offloading an application folder to another hard drive, and much more. 
Apple Watch is generally very stable and rarely needs to be rebooted or restarted, but sometimes it can become stuck, frozen, unresponsive, or a feature of Apple Watch may stop working as intended. Typically if those situations arise, you can get Apple Watch back to working order again by issuing a forced restart of the device.
