645 PRO Mk III has been designed, from the ground up, for professional and serious amateur photographers. So it works the way a camera works—and it’s the most powerful camera app we’ve ever seen!
You have instant access to everything that can be controlled on an iOS camera.
That means fully manual exposure control, as well as semi-automatic Shutter Priority and ISO Priority, together with fully automatic exposure with a choice of spot or matrix metering. Automatic and semi-automatic modes also include ±3 Ev. exposure compensation, while the on-screen meter lets you judge your manual exposures to perfection.
It means the choice of AWB or a selection of white balance presets—and even the ability to create and save a completely custom white balance.
And it means manual focus override—just swipe your finger up and down the viewfinder to control the lens position. And you even get focus-peaking to help you identify what will be in perfect focus!
And you have all the information you need, all the time, including real-time exposure metering, real-time ISO and shutter-speed readings, Ev, real-time GPS data and a choice of histograms. And many aspects of the interface can be customized, so you can—for example—configure the Shutter Release button to behave the way you want.
645 PRO Mk III—TOP-QUALITY OUTPUT
645 PRO Mk III combines the ultimate in lifelike "film look" output with the ability to save completely unprocessed image data at the highest quality possible—as Camera RAW.
Its gorgeous Film Modes are inspired by classic film stock as used by top photographers from the 1960s through to the present day—and if you want to edit them, and save custom, personalized films, you can. Meanwhile its unprocessed images are just that—ready for later post-processing or to be used "as is" for reportage.
Whether you shoot Film Mode, unprocessed or both, you have the choice to save in HI-Quality JPEG, MAX-Quality JPEG, or—for top image fidelity—TIFF.
And you have the option to shoot in one of seven formats, from square 6x6 to panoramic 6x17, all inspired by classic Medium Format cameras. Also inspired by film, you can add one of 21 Photo Filters, all with fully-adjustable densities.
You'll get photographs from your iPhone like you never imagined!
Drawing its inspiration from the obsession with quality embodied by top-end Medium Format film and digital cameras, 645 PRO Mk III exists purely to help you use your iPhone as a tool for composing, taking, saving and sharing the finest possible photographs.

Ratings and Reviews
Hands down best photography app for IOS - and incredible support
This is by far the best app that I have found. My Canon 60d doesn't see nearly as much action since I loaded 645 Pro Mk III on my iPhone.
Aside from the outstanding performance of the app itself, the support is incredible. I had upgraded my iPhone to IOS 11 yesterday, and it caused a glitch with saving of photos to the camera roll. I had shot several photos of the Mars/Venus conjunction at sunrise this morning, and then could not find them. I sent a support message at 6:15 am, and had a reply from Mike Hardaker within minutes telling me how to correct the problem. (IOS 11 removes 645 Pros access to photos, and then when you reset it, it doesn't update until you completely shut down the app).
Best app investment I've ever made.
If you’re interested in the technical aspects of photography and want to capture better images with an iPhone, 645 Pro has a lot of options. You can use filters in the camera to get a particular effect or save an unfiltered image for post. Or the app can do both, it’s highly adaptable. The on-board 58 page User Guide details the many configurable functions. 645 coaxes every thing out of the iPhone to make is as much like a DSLR as possible. And it has old-school film features: if you want to simulate shooting with 35mm Kodachrome and a #85 warm filter or 6x7 b&w street photogrsphy with an orange filter, this app can do it.
• the app simulates glass filters (including grads) and emulates a dozen b&w and color film stocks.
• it also has every film size format, from 6x6 to 645 to 6x17.
• I’ve found the developer to be responsive to inquiries and he updates the app regularly.
I give it five stars. ★★★★★
Good quality in TIFF but unstable
While I like this app and find the TIFF format to be a big improvement over JPEG, the instability on my iPhone 4S makes the app frustrating to use. When it's not crashing to the home screen, it's locking up or refusing to respond to shutter presses. So much potential, but the endless missed shots make me regret my purchase. This app needs work.
Update: Since posting this review, I've moved on to other hardware: first an iPhone 6 Plus and now an iPhone XS. Initially, it ran well on the 6 Plus and was a pleasure to use. Unfortunately, this is no longer the case for the 6 Plus and that has not been resolved with the move to the new XS hardware. At this point in time – October 2018 – the live view lags; the volume buttons no longer work as a hardware shutter release; and file saving is unreliable. It is essentially unusable. That's a real shame.
With Family Sharing set up, up to six family members can use this app.
