Wider or taller images by overlapping and blending photos

Use it when:
  • taking panorama images
  • you can not get far enough away to fit everything in one shot
  • your originals does not fit in your scanner
  • your cell phone has too low a resolution
  • you want to add surroundings to a shot of an event which has now passed
  • you want to make large images suitable for the "Ken Burns" effect

Open, Stitch & Save

To make it quick and simple to use DoubleTake there are several ways getting images into DoubleTake and saving the resultt.


  • Drop the images on DoubleTake.
  • Choose Open from the File menu, and select all the images at once by holding down the shift key.
  • Choose New from the file menu, and drag the images into DoubleTakes window.
  • Copy & Paste from iPhoto (version 5)


DoubleTake will make a first guess on how the images fit together. You can then freely move the images around and tweak the overlaps as desired.


Save in TIFF, JPEG, PDF, PNG, doubletake's own format, or copy the result to iPhoto with copy and paste.

The images should be taken at the same distance or be in the same resolution. But they need not to be the same dimensions.

The sample images

Are chosen because they require different actions for a good result.
  • Golden Gate: try the transparency feature and adjust the seam so spread the color differences in the sky.
  • Stonehenge: switch the images around. Even if the grass matches in color, this is not the intended arrangement. Notice automatic scrolling and that there are no "canvas" boundaries. This image can also benefit from some fisheye distortion.


DoubleTake costs €16.95 excl. VAT, and I hope you will find it useful. When you have paid, you receive a license number which you enter together with your name in the Registration Window.
When you register, the "DoubleTake" watermark disappear from the image.

Upgrade from previous versions DoubleTake is free.
To purchase DoubleTake, click the Buy button in the Registration Window, or visit my web shop at Kagi (international) or eSellerate (in English only).


The license to DoubleTake is a non-exclusive single user license. The license to use DoubleTake is personal and not for rent, lease, resale.

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 iimage 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

  • Performance enhancements of all operations.
  • 2 Crop modes: outside all the images, or inside.
  • Fish eye correction for shorter focal lengths.
  • Paste of images from iPhoto. Copy & paste of the merged image to iPhoto

  • Automatic guess of arrangement is now enabled for more than 2 images.
  • Delete of accidentally imported images. Select it with one click, and chose "Delete".
  • Fixed crash when moving images with the keyboard.
  • Larger handles showing which image is selected for keyboard control.
  • Fixed problem reading TIFF files with higher resolution.

Bugs - July 23

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.

Please report bugs to Henrik Dalgaard -


You can test DoubleTake right from the disk image. To install it drag the DoubleTake application from the disk image to the Applications folder on your computers hard drive or anywhere you wish to keep it.


Drag DoubleTake to the trash.
