The switch to v2.0 brings a changelog in the Store description:
- New UI, redesigned and optimized
- Added black and white mode (may be CPU-intensive, disable if app runs slow)
- HDR modes are now free
- Many bug fixes and improvements
Version 2.0 is working pretty well on my Lumia 950 XL:
Showing off the new Black and White mode, but note also the new global settings icon, bottom left, and the simpler control cluster on the right.
The global setting pane is all graphical still, but well done - just toggle and tweak away to your heart's delight....
The attraction of ProShot, as ever, is the control, not just over resolution and shooting parameters, but of bitrates, compression factors, and so on. Plus a very DSLR-like interface that has a learning curve but which you'll find very useful with practice.
You can buy ProShot v2.0 in the Store here.
