Products Digital backs

Leaf previously a division of Scitex and later Kodak, but now a part of Phase One.[1] Leaf manufactures high end (medium format) professional digital photography products. In 1991, Leaf introduced the first medium format digital camera back, the Leaf DCB1, nicknamed ‘The Brick’, which had a resolution of 4 million pixels (4 megapixels). As of January 2011, Leaf produces the Aptus line of digital camera backs, ranging from 22 to 80 megapixels. Until 2010, Leaf also produced photography workflow software.

Products

Digital camera backs

After Leaf's DCB, the digital backs evolved into two product lines, the Aptus and the (now discontinued) Valeo. The main difference is that the Aptus models have a 3.5-inch touchscreen, where the Valeos have no on-board display. The Valeos can still be used untethered by using the DP-67 software or the more recent WiView software on a Compaq iPAQ. The iPAQs are connected via Bluetooth with the digital backs. For untethered usage, you will need battery packs for both the Aptus and the Valeo, otherwise the back must be powered via a Firewire connection to a computer. The Valeo models need a Leaf Digital Magazine as well for untethered use, where the Aptus models have a Compact Flash slot.

Current models

Credo is the latest generation of digital camera backs from Leaf, and the first new back since Phase One purchased Leaf that does not base itself on previous models. Some of the changes are that the back no longer has a cooling fan, but instead is built on more advanced passive cooling. Also to be noted is the new high resolution iPhone-like touch screen which no longer require stylus pen. Back also use the Phase One OS which makes the back boot up in less than a second. This previously took up to 10 seconds on Aptus units which used Windows CE operating system.

Aptus II digital back

Aptus II models are very similar to corresponding previous Aptus models, with the notable differences:

  • Live view available with Phase One 645AF and 645DF bodies (+ Mamiya AFD III & DF), no dongle required. Live view is available on Capture One with large format bodies for legacy Aptus 22 and up, Live View dongle is no longer required.
  • Camera controls (aperture, shutter speed and shutter release) on Phase One 645AF and 645DF bodies (+ Mamiya AFD III & DF)
  • Faster shooting speed, shot-to-shot and faster transmission to tethered computer
  • Firewire 800 connection replaces Firewire 400
  • Slightly different color response

Camera Mounts

The Aptus-II models are equipped with a specific mount to fit one of the following camera systems:

Brand Type
Phase One 645AF, 645DF (Same mount as Mamiya)
Mamiya 645DF, 645AFD (I+II+III), RZ67 (Pro II), RZ Pro IId, RB67
Hasselblad H-system
Hasselblad V-system (not 200 or 2000 versions)
Leaf AFi Also known as "Rollei Hy6"
Contax 645AF
Fuji GX680II, GX680III - not a Leaf mount; adapter available from 3rd party
Bronica SQA, SQAi, ETRSi (No longer made)

It is impossible to convert the mount of a digital back for a different medium format body via adapter or conversion plates, because the sensor would then not sit within the film plane (since the sensor needs to sit the same distance from the lens that the film would). Such conversion may be possible by sending the back to Leaf to be physically reconfigured, depending on the specific model.

Any mount can be used on view cameras by using the correct adapter plate, for example: Alpha, Arca, Cambo, Horseman, Kata, Linhof, Sinar, Toyo, Rollei X-Act2, and other via Leaf Graflok or third party adapters. This is because view cameras have an adjustable focal plane

The AFI backs (in the Discontinued Models) are specifically designed to work with Sinar and Rollei systems.

Accessories

Leaf Digital Magazine

The Leaf Digital Magazine, or LDM, is a portable, small Firewire-powered hard drive that enables a digital back lacking a Compact Flash slot to be used untethered. There are three models, the 5GB, 10 GB and 20 GB. It can be mounted in the U-bracket, which can also contain two (smaller than normal) batteries. This U-bracket can then be mounted underneath the camera. There are short Firewire cables available to connect the LDM to the Leaf digital back.

Software

Capture One / Capture One Pro

Capture One is a tethering software, Raw image format converter and workflow software which enables photographers to deliver ready-to-use images with adjusted color and detail. It is designed to create very high image quality and provides a series of tools created to match the professional photographer's daily workflow. Capture One replaced Leaf Capture as tethering and processing software for all Leaf Aptus and Aptus II backs.[5]

Leaf Capture

Image capture workflow software, available for Apple Inc. OS X and Microsoft Windows. Leaf capture is no longer developed, and is Replaced by Capture One for all Aptus and Aptus II models.

  • Image comparison
  • Camera control (of non-manual cameras)
  • Loupe tool, focus preview
  • Realtime live view display
  • Grid and layout overlay
  • Color temperature and tint sliders
  • Adjustable histogram
  • Moiré removal tool

Note: From v11.2.9 on only supports Aptus models [6]

Leaf Capture Remote App / Server

Used together, allows browsing of your "Shots" folder on wireless devices (iPad, iPod Touch and iPhone). The app works via the device's wireless local area network connection with Leaf Capture Server running on a host computer [7]

Leaf WiView

Leaf WiView is an update of the DP-67 software. It is an application that enables you to have wireless control (via Bluetooth) over your Leaf imaging module to view and edit images on an HP iPAQ Pocket PC as you shoot. Before you begin working with Leaf WiView you must install the corresponding application on the iPAQ Pocket PC. Follow the procedure for your operating system.

  • Known supported iPAQ models: hx2100, hx2400, hx2700, hx4700, rx5900, 110, 210.[8] It is important that the iPAQ has either 240x320 or 480x640 screen resolution, otherwise a part of the screen will be digitally masked off (unsupported models).
  • Known supported Leaf models: Valeo 17wi, Valeo 22wi, ...

Leaf DP-67

The Leaf DP-67 application on an HP iPAQ allows wireless remote communication with the Leaf Valeo digital camera back via Bluetooth. The advantages of large storage space for your images and full control over the capture process are maintained by the Leaf Digital Magazine and Leaf DP-67 (iPAQ) display and control devices.
