DoubleTake

Version 2.7.3 - Oct 7 2024

About DoubleTake

DoubleTake is for Mac users who like compact cameras, but sometimes wish they could magically pull out a wide angle lens of their pocket, or plug in a sensor with a few extra megapixels for that large print.

DoubleTake handles this by giving you both automatic and manual control of how to stitch photos perfectly, with simple drag and drop.

Price

DoubleTake costs €16.95. When you have paid, you receive a license number which you enter together with your name in the Registration Window.

• Fix: QuickTime VR movies could cause QuickTime 7.6.x to crash on Mac OS 10.5.8 and 10.6.8

Version 2.2.6 - July 20 2011

• I knew this a good while ago: DoubleTake works on Lion! If you already have version 2.2.6 you don't need to upgrade.

Version 2.2.6 - Feb 28 2011

• New: added support for swipe, pinch zoom and rotate for the Magic Mouse and Trackpads.

Version 2.2.5 - Feb 25 2011

• New: added "Direction" in the geometry window to allow for perspective when turning the camera and not using the cylindrical projection (where this is automatic)
• Fixed: on Snow Leopard photos taken in portrait mode on cameras with orientation sensor now show up properly (as on earlier versions of macOS).
• Fixed: some of the menu items were not enabled when only one image was open in DoubleTake.
• Changed: removed a lot of old code needed for Mac OS 10.4 but which is deprecated on 10.6 and forward.
• Checked: that DouybleTake works on the fist developer preview of macOS 10.7 "Lion".
• Requirements: macOS 10.5.8

Version 2.2.4 - May 5 2010

• New: added the menu option to turn stitching off. This is useful for photo montages where the blends don't make sense
• New: added the menu option to snap images to edges when draggging. This is useful for photo montages.
• Changed: when dropping images one at a time, the place the image is dropped becomes its initial position. This is useful for photomontages and for better manual control of. If dropped on top of existing images DoubleTake will try to find a more appropriate spot.
• Changed: images are now drawn in the order they have been last selected. Useful when stitching is turned off.
• Fixed: crash when stitching images of different size (likely for photomontages)

• Fixed: crash when chosing Next from the Overlap menu and there are no overlaps.

Version 2.2.2 - June 2 2009

• Added: menu items for saving to Aperture and Lightroom. You can add keyboard shortcuts via System Preferences -> Keyboaard and Mouse.
• Fixed: problem with vertical lines in panoramas on Macs with an Intel Core 2 Duo Processor and 3 images overlapping.
• Fixed: rare crash on Intel Core 2 Duo processor Macs, when dragging in many large images.

Version 2.2.1 - May 18 2009

• Fixed: interactive feedback on G5 Macs on macOS 10.5.7.
• Updated: RAW photos stitched will save as TIFF when using the shortcuts to Aperture (tips) and iPhoto.

Version 2.2 - February 6 2009

• New: 64 bit support - on newer Macs.
• New: Toolbar buttons for saving the result and getting it imported into iPhoto or Aperture.
• Fix: Crash when printing posters
• Fix: Crash when switching in and out of DoubleTake several times when doing more than one panorama.
• Fix: Files saved for iPhoto now get a proper extension
• Fix: Files saved for iPhoto get a file name based on the image numbers if they are sequentially numbered (quite common)
• Fix: Files saved for Aperture now import into Aperture in a project named DoubleTake
• Fix: GPS Coordinates made by iPhone are now preserved in the final panorama

To save panoramas larger than 100 million pixels you need a Mac with an Intel Core 2 Duo processor or newer and macOS 10.5. The G5 should support 64 bit too. The upper limit of saved files is not known - but I believe this is limited by patience, file format limits and the appication in which you wish to use the saved image.

When running 64 bit QuickTime VR is not supported, and neither is stitching of QuickTime movies (not many have ever tried this).

To turn on 64 bit mode use Get Info in Finder and uncheck the 32 bit checkbox

To turn off 64 bit mode use Get Info in Finder and check the 32 bit checkbox

Version 2.1 - April 16 2007

• New: keyboard shortcuts (as in PhotoShop) for zoom to fit and zoom to actual pixels
• Fixed: the with and height fields were disabled on a 2nd save
• Fixed: the selection of images was lost when zooming
• Fixed: ICC profile was not written in TIFF panoramas if the photos were 16 bit

Version 2.0.3 - July 19 2006

• New: Rotate left and right for all images
• Fixed: a memory leak which could make DoubleTake run out of memory after having stitched about 30-60 images
• New: Control click in DoubleTakes window to force it to arrange images in horizontally, vertically or sort by time taken if the default arrangement does not pick the right solution. See the Chamhord sample for such a case.

Version 2.0.2 - July 9 2006

• Fixed: redraw problems with "blank" images after some undo operations. They would redraw again if nudged a bit
• Fixed: QTVR now opens at the zoom and tilt corresponding to the last view in DoubleTake before saving. This did work except if the zoom was at the back seam
• Fixed: the 360 degree seam would not enable if the 2 rightmost images were almost on top of each other
• Improved: the case where the .doubletake files have been moved from the images now asks where they have been moved to.

• Adjust and Geometry tools - try the Samples
• Rotate mode - hit r on keyboard - notice how the corner handles change
• Scale mode - hit s
• Free Perspective mode - hit p
• Normal move mode - hit n
• Image menu
• Exposure matching
• Align button for making manual re-orderings snap together
• Rotation of all selected images at once via the geometry window.
• QTVR save option

1.6.2 June 28 2005

• Performance improvement when saving. Mac OS 10.4 is faster for this.
  
• Translation to Dutch - (not proof read yet).
  

1.6.1 June 15 2005

• Banding problem when stitching overexposed images fixed.
  
• Translation to Italian: Pierino Donati - Studio tecnico geom. Pierino Donati

1.6 June 11 2005

• A few extra Save options
  
• Printing
• G4 requirement for Tiger removed
  

1.5 April 13 2005

• Redrawing of the crop frame polished, and a redraw problem is fixed
• Fixed a problem which occurred If you dragged in the images one at a time. DoubleTake could go into infinite loop, and be come unresponsive.
  

1.5b2 - April 12 2005

• You can now save a DoubleTake document which contains references to the original images and how they are arranged. This is handy if you want to come back and do minor adjustments later.
• You can adjust images currently being worked with in DoubleTake in other applications, as iPhoto. If you find one image which needs a bit of rotation or exposure correction, you can do this there and save it. When you return to DoubleTake it will notice that the file has been updated and reload it.
• Images rotated, with tag only rotation, will now show up correctly.
• The x-ray mode of overlapping the images has been replaced by transparency, as this is much simpler, faster, and require less memory. It also has a cool visual effect when DoubleTake blends the overlaps.
• Keyboard sort cuts. See the menus. Arrow keys move the selected image, and turns it transparent for 2 seconds. Useful for fine tuning image positions. Tab selects the next overlap, useful when you are zoomed in.
  
• Dragging more than one image. Select them with the shift key held down.
• Locking overlaps. See the overlap menu, and use the additional shortcut at the space bar.
• Better sorting when opening many images. It sorts by filename, and tries both backwards and forwards order. When sorting fewer than 9 images all possible arrangements are tried. This does not mean that it gets it perfect every time. The Stonehenge example shows why.
• Spelling fixes in the German translation. Danish translation added. I have looked up more words in Japanese. I am happy to receive corrections to the translations.
• New icon
  

1.5b1

• Performance enhancements of all operations.
  
• 2 Crop modes: outside all the images, or inside.

Bugs and Improvements - in version 2.0.1

• Improve documentation on QTVR.
• Make gallery.

Bugs - in version 1.6.2

DoubleTake requires "Millions of Colors" in your "system preferences" to blend images properly. It is a bug not to put up an alert about this (like iPhoto does). DoubleTake use the graphics card, and this is even more true for the next version.
