- | Stereo and rocking are powerful ways to show off the 3-D structure of your subjects. With Zerene Stacker, they are now also easy! Instead of shooting a separate stack for each viewing angle, Zerene Stacker allows you to shoot a __single__ stack and then use synthetic rotation to make multiple images that can become a stereo pair, a rocking animation, even rocking stereo. | + | Stereo and rocking are powerful ways to show off the 3D structure of your subjects.

- | To produce any other format, you must use some external program. The free software StereoPhoto Maker (http://stereo.jpn.org/eng/stphmkr/) allows cropping and can generate output in a wide variety of formats, including color anaglyphs for viewing with red/cyan or red/green glasses. Animated GIF images for rocking displays can be generated by programs such as Adobe’s ImageReady and the free GIMP software (http://www.gimp.org/). It can also be done with regular Adobe Photoshop, using Timeline animation as described at [[https://helpx.adobe.com/photoshop/how-to/make-animated-gif.html]]. Longer sequences can be generated as looping movies by programs such as Apple’s QuickTime Player Pro (http://www.apple.com/quicktime/pro/, for Macintosh or Windows). | + | To produce any other format, you must use some external program.

If you are on a Windows computer or have Windows emulation software, you should consider getting a copy of the free StereoPhoto Maker software (http://stereo.jpn.org/eng/stphmkr/). It provides an excellent viewer that allows displaying a single image in various display formats, including crossed-eye, parallel viewing, red-cyan anaglyphs, and many other less common forms. It also provides a variety of editing capabilities. Cropping is especially handy, since this feature is not yet built into Zerene Stacker. | If you are on a Windows computer or have Windows emulation software, you should consider getting a copy of the free StereoPhoto Maker software (http://stereo.jpn.org/eng/stphmkr/).

- | + | ===== Calculating Shift Based On Viewing Angle ===== | |
+ | |||
+ | You can calculate the shift percents if you know three things: | ||
+ | * subjectStackWidth = frame width at the subject | ||
+ | * subjectStackDepth = stack depth at the subject | ||
+ | * viewAngle = viewing angle, measured as angular deviation from the usual straight-on view | ||
+ | |||
+ | Given these values, the calculation is straightforward: | ||
+ | |||
+ | * maximumShiftInX = tan(viewAngle) * (subjectStackDepth/subjectStackWidth) * 100% | ||
+ | |||
+ | For example, if you want a viewing angle that is 4 degrees off-axis, with a stack whose frame width is 10 mm and stack depth is 5 mm, then you would calculate as follows: | ||
+ | |||
+ | * subjectStackWidth = 10 | ||
+ | * subjectStackDepth = 5 | ||
+ | * viewAngle = 4 degrees | ||
+ | * maximumShiftInX = tan(4 degrees) * (5/10) * 100% = 3.4963% | ||
+ | |||
+ | If you're doing the calculation in Excel, then remember to convert degrees to radians. The formula in Excel would be: | ||
+ | |||
+ | * =TAN(RADIANS(4)) * (5/10) * 100 | ||
+ | |||
+ | For generating stereo pairs, simply use viewAngle = (plus and minus) separationAngle / 2 . | ||
+ | Viewing angles that are off axis vertically use the same rules, substituting height for width and Y for X. Note that this means the same angle will require different shift percents for X and Y, in proportion to the frame dimensions. | ||
