Nokia's Jason Gregory has a little bit of the showman in him, since in the video below (don't worry, it's only four minutes long), he takes the time to set up each demonstration perfectly. He runs through his four favourite camera tips/tricks on the Lumia 1020 and, trust me, you'll be blown away by the end result of the 'shutter speed' one.

The four tips/tricks demonstrated are:

• Zoom like never before - concentrating on re-zooming and reframing, with a really cute example
• Shutter speed control - showing how you can vary this up even to 4 seconds - watch what gets created!
• 'Powerful Xenon flash' - using a spinning globe to illustrate how the Xenon flash freezes even quick motion in precise detail
• Nokia Pro Camera and its tutorial - looking at changing focus manually, ISO, etc. plus a look at the rather cool interactive tutorial

Here's the video then, maximise it and max the quality if you can, as usual:

Nice work, Jason. The 'tutorial' section inside Nokia Pro Camera is part of a modern (and very welcome) trend on all mobile platforms* to make more of a smartphone's biggest assets (e.g. the large touchscreen) to help the user learn and be more productive. Yes, the 'interaction' in the tutorial is somewhat pre-programmed, but it certainly beats twenty pages in a paper manual.

* I've noticed this in Samsung and HTC Android devices too - this isn't Nokia's invention, per se, but it's great that its Windows Phone applications are also becoming more and more friendly to novice users.
