Being able to draw right onto your photos to make adjustments, manipulations, etc has always been my dream. So far there are only a few well known products that can do this; Wacom's Cintiq Tablets, Microsoft's Surface, and Apple's iPad with 3rd party pens. Finally, Apple has created a product that will change photo editing forever; The iPad Pro with Apple Pencil.
The iPad Pro is a 12.9" iPad made with multitasking in mind. While a stylus is a terrible idea for a phone, it is an incredible idea for a tablet. Especially when the Apple Pencil understands pressure, tilts, and more. The Apple Pencil charges by using the iPad's Lightning connector and gives you 30 minutes of battery life in 15 Seconds so, if you are out-and-about, you can quickly charge your Apple Pencil for on the go drawing. Besides Apple's Pencil's functions, the most impressive part has to be the Pencil's tip. It is by far the smallest, most pencil-like tip I have seen on a stylus. It is going to make drawing much more realistic and comfortable.
So why is the iPad Pro better than Microsoft's Surface or the Wacom Cintiq Tablets? It's simple; The App Store. Apple's App Store has more developers than Apple knows what to do with. Offering drawing, editing, and 3D app developers the Apple Pencil to support in their apps is going to change the way every app functions. Imagine using Photoshop/Pixelmator to edit photos with your Apple Pen. Think about the changes they'll be able to add to Lightroom mobile when they know you can edit even further then you have ever been able to before. Imagine when secondary display apps start supporting the Apple Pen and you'll be able to go home, connect to your desktop, and edit photos right on your 12.9" iPad while seeing the edits live on your monitor.
I, for one, can't wait for the iPad Pro with Apple Pencil. I just want to get my hands on one and see what it's like to edit some photos. The iPad Pro and Apple Pencil come out in November which give developers plenty of time to update their apps and add new functionality. For more information, check out Apple's website.
