Phocus 3.6 Windows read-me
May 20th, 2021
Installation
To install Phocus, run the installation bundle. This bundle contains Phocus, and Hasselblad
Device Drivers. The Microsoft .NET Framework 4.8 is required and will be automatically
downloaded and installed (it can be obtained manually from
/fwlink/?linkid=2088631 if an offline install is required).
Compatibility
Phocus is supported on Windows 7 Service Pack 1 64-bit, Windows 8 64-bit, Windows 8.1
64-bit and Windows 10 64-bit.
System Requirements
Graphics adapters
You should be aware that Phocus utilizes the processing power of the GPU - therefore
using a PC with a high-performance GPU is definitely an advantage.
Memory
We recommend at least 8GB of memory
Supported products
Image files from all Hasselblad USB and FireWire based digital camera products are
supported. Tethered operation will work with the same range of cameras except for the
first generation Ixpress series.
Capture of micro-step images is not supported.
Scanner 3F files are not supported.
3F files generated by Phocus are not backward compatible with FlexColor!
Functionality Level
The Windows version only supports tiff and jpg as 3rd party files.
New features in 3.6
Focus bracketing
The Capture Sequencer tool now introduces an additional tab for control of focus
bracketing. For convenience it includes controls to turn live video on and off and to control
the focus distance.
There are 4 possible sweep modes:
▪ Towards Infinity
▪ Towards Near Limit
▪ Symmetric
▪ Specify Limits
The first 3 basically work like the focus bracketing feature build into the X1D cameras.
You select the step size from 5 different options, specify the number of frames, focus the
camera at the outer range of the sweep and click play to start the sequence. Step sizes
will take the currently chosen aperture into account.
In the Specify Limits mode you will also select a step size, then move to the position for
the start of the range and click Sweep Limit 1, thereafter focus at the end of the range
and click Sweep Limit 2. Now you are ready to start the sequence.
The Specify Limits mode is available for X series cameras only and both camera and lens
need to be running the latest available firmware.
Film grain tool
The new film grain tool will enable a highly flexible simulation of film grain.
There are basically 3 types available and for each you can vary 4 parameters which are
amount, granularity, roughness and color. Roughness might need further explanation - it
basically controls the perceived sharpness of the grain.
Adaptive chromatic aberration correction
The standard correction of chromatic aberration that has been the only option until now
relies on theoretical lens data based on the lens design. In some cases lenses can have
slight deviances from the theoretical data, of course more so if having been subjected to
rough handling. Also you may be using 3rd party lenses for which we do not have
theoretical data. To cover those cases we have added a new Adaptive option for chromatic
aberration removal. This option will perform the correction based on image analysis.
This also makes CA correction available for 3rd party lenses. For these the lens correction
tool will show the usual UI for specifying a V lens - if you just leave this at "Other" then
it's still possible to select the adaptive chromatic aberration correction.
Note that the current implementation limits the possible movement of color channels to 4
pixels so in some special situations that will not be enough.
Misc improvements
Apart from a number of fixes this release also includes:
• correction support for more V lenses
• improved XH 0.8 lens corrections
• support for IT8 color targets
• improved chromatic aberration correction for multi-shot images
