The Photos app in iOS 8 also makes post processing easier and more powerful, with the addition of editing features and extensions. This lesson shows you how to use the editing tools: The Crop tool is no longer just for cropping! You can now straighten crooked images too. Photo editing tools include auto enhancement and filters but also the addition of smart adjustments: Light (you can alter exposure, highlights, shadows, brightness, contrast and black point), Colour (colour, saturation and cast) and B/W (this provides a variety of black and white adjustments such as intensity, neutrals, tone and grain. This lesson will also explain how to use photo extensions. This means you may no longer need to open a separate photography app to use its editing tools. Now, you can add its tools to the Photos app.
