645 PRO Mk III

By Michael Hardaker

Open iTunes to buy and download apps.


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 combines the ultimate in lifelike "film look" output with the ability to save completely unprocessed image data at the highest quality possible.

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.

"645 PRO takes the best iPhone photos you have ever seen"
-- Charlie Sorrel, Cult of Mac

"My number 1 camera replacement app"
-- Glyn Evans,

"If you’re looking for a camera app which leans toward a professional pallet of tools, then 645 PRO is certainly the best there is"
-- Ben Reid, Redmond Pie

"Not only do you get what is arguably the best, serious-shooter, camera for the iPhone but you also get a level of customer care, devotion and attention to detail that you will be hard pressed to find elsewhere on the App Store. In short: 645 PRO is a steal. Buy it today!"
-- Aaron Stanley, Appsolute Reviews

Wise features, cumbersome interface

The greater control over focus, exposure, and image quality are, of course, quite welcome, but the film/grain emulation as well as color filtration for greyscale images are alone worth the price of the app. Someday Instagram will catch on to these tweaks.

The interface, however, inexplicably emulates that of a physical point and shoot camera, instead of using the possibilities of the iPhone's hi-res touchscreen. The simulated three dimensional is is a distraction, and the interface simply can't rotate properly for square/portrait orientation (shooting square is most natural in the vertical). An actual camera has limited surface area and thus has to cram minimal symbols into circular buttons. No need for that here.

Tapping for a pop up menu and sliding for selections would ease the photographic process. Right now, valuable features are buried four screens deep in a menu that acts exactly like it only has the directional arrows of a hardware camera.

The filter menu brings up a needless 3D carousel when a two-d layout with fixed locations would be faster. A slider would be vastly preferable to tapping tiny increments. Saving favorite filters would be perfect.

HDR would be a godsend but I imagine it's expensive to develop.

Still, I keep coming back to this app because of the film and grain emulation. I hope the interface is eventually streamlined.

Nearly perfect camera!

I had many issues with earlier versions, but with a new version, a new 5s phone, and iOS 8, it's great, nearly everything I want in a camera app. I have about a dozen different camera apps, each because they have features I could only find in each specific app. With this latest release it looks like I can delete three-fourths of those. If this adds panorama, HDR, repeating interval timer, and a couple other features, it will be the only app I need. It has a beautiful interface, well thought out controls, packed with features that compete with expensive SLRs, it's great as-is and regularly getting better!

A Bit Clumsy But Full Shutter & ISO Control

This app does not have the smoothness of some manual photo apps – for example, you have to repeatedly and laboriously hit a series of plus or minus signs to set your parameters. But it is the only one I've used that allows you to capture photos at ISO 2000 at 1/2 sec. Other apps allow you to set those parameters, but when you look at the EXIF data afterwords you find that they actually shot at 1/15 sec. As such, this is a must-have app for anyone interested in total manual control in low light situations.
