Phocus 1.1 - read me
New features since V 1.0.1
Rotation
Controls for adjusting image rotation has been added to the crop tool. These include buttons for changing rotation in 90° steps and a Straighten slider that allows you to correct image alignment by +/- 20°. There's also a Straighten picker tool - with this tool selected you can draw a line in the image along a part that is supposed to be either vertical or horizontal and the straighten value will be set accordingly. Finally it's also possible to freehand rotate the image in the viewer when in crop mode - to do this you need to click and drag outside the crop while holding down the alt button.
Cropped view
Unless the crop tool is selected the viewer will now only display the cropped part of the image. Likewise only the cropped image will be used as thumbnail when the Show Crop option is selected.
Custom white correction
This feature allows you to correct for things like cast issues when using tilt and shift. User interface for this has been added to the lens correction tool. The procedure is as follows:
1) Make a calibration image of a neutral gray surface - the best results are obtained by using an opaque filter. The capture can be made either tethered or untethered.
2) The calibration image needs to be available as a 3F file so if it was captured untethered you will need to import it.
3) Load an image where you'd like to apply the correction
4) Select the thumbnail of the calibration image and click the Create button found in the Lens Correction tool
5) You will be prompted for a name of the correction - it's a good idea to use it to describe things like the lens and aperture used.
6) You have now created a custom white correction - to see it's effect on the currently loaded image check the Custom white checkbox.
7) To apply the custom white correction you can follow the same methods as when applying any other adjustment to a range of images using either the Modify dialog or the Modify Lens Corrections of Selected Files option in the Lens tool preset menu.
If this correction is one that you might want to save for future use you can simply create a Lens Adjustment preset with the correction active.
Overlay
Next to the grid button you will now find a button that turns on display of an overlay image. The image can be selected by dragging in a JPEG, TIFF or PNG file. If you open the overlay options palette by either right clicking the button or selecting Overlay options from the View menu you can determine opacity and scale. The image can be dragged by clicking and dragging while holding down the alt button provided the crop tool is not active.
Moiré removal
The algorithm has been improved - this should lead to more precise detection and fewer artifacts.
Performance improvements
The speed of browsing, zooming, dragging and comparing images has been improved.
Hand tool
This tool simply lets you drag the image around.
Firmware Update
This function located in the File menu allows you to manually update a connected Hasselblad product when future firmware updates become available for download from our web site.
Miscellaneous
You can now option-click the approval level filter buttons in the thumbnail options view to select only the clicked color.
With the thumbnail view active the cmd-0 Fit to Size shortcut will now resize the thumbnails so that a single image fits within the view.
It's now possible to expand/collapse a folder in the browser by double clicking.
A thumbnails only layout option has been added - the short cut is alt-cmd-4.
