Since its launch in April, 645 PRO has proved itself very popular with the iPhone photography community—more popular than we ever hoped! This has let us benefit from a great deal of feedback when developing the second major release of the app.
And now it’s here! 645 PRO Release 2.0 is NOW available for download from the iTunes App Store.
And it’s (nearly) here! Yes, 645 PRO Release 2.0 will be available for download from 10:00 UTC/GMT tomorrow, 15 September 2012. (That’s 03:00 Pacific, 06:00 Eastern, 11:00 BST, 12:00 CEST, and so on…)
- Faster
- More robust
- More capable
than ever before.
Faster, stronger…
Many core elements of the software have been re-written to optimize performance in various areas, from the real-time preview and UI responsiveness through to file save times. There has also been a huge push to ensure that it is completely stable in operation, even when challenged by external factors (such as misbehaving third-party apps). And everything has been through an extensive pre-release testing phase.
Bigger, better…
Then there are the new features:
A pair of new photo filters have been added, providing a choice of neutral graduated filters that can help bring landscape skies to the fore. And the way that photo filters are accessed has also been modified, making it easy to toggle between a previously set-up filter setting and no filter:

The Film Modes have received some subtle yet sophisticated mods that help to overcome the inherent iPhone tendency to blown-out (clipped) highlights. Quite simply, these bring image highlights to life.
645 PRO now supports automatic interface rotation (lockable, for those who prefer a fixed orientation). And photographers using externally mounted DSLR lenses now have the ability to “flip” the viewfinder image to compensate for the inverted image they get from their add-on lens kit.
Behind the scenes…
But the bulk of the additions can be seen after a photograph has been taken. Press the View/Share button and you’ll see that Instagram has been added to the sharers. You also now have an Open In… option, that will open the image you are viewing in any application installed on your iPhone that exposes an interface for the file type in question (including Dropbox).

And if you choose to save unprocessed dRAW TIFF files to 645 PRO’s private Documents folder, you’ll see a new icon leading you to a space where these files can be managed in-app, rather than via iTunes File Sharing.
You can view and delete your TIFFs, use the Open In… functionality with those apps that support it, and copy images to Camera Roll for later editing using another app, or for syncing to your computer.

Since its launch, 645 PRO has been the most powerful iPhone photography app available.
Now it’s better than ever!
