about focus stacking

Focus stacking (also known as focal plane merging and z-stacking or focus blending) is a digital image processingtechnique which combines multiple images taken at different focusdistances to give a resulting image with a greater depth of field(DOF) than any of the individual source images. Focus stacking can be used in any situation where individual images have a very shallow depth of field; macro photography and optical microscopy are two typical examples.

Such as a spider picture to demonstrate

at f/11 DOF is quite limited

with 8 pictures at f/11 stacked,we can get better result.

Usually,we can process focus stacking picture by Helicon focus,Zerene-Stacker , CombineZP ,Photoshop,etc.

What we do

Usually,when we take focus stacking pictures,screwing the macro rail or micrometer(used in high magnification) by hand are popular in focus stacking photograph.

But it’s hard to get precise step length and sometime it’s boring if there are a lot of steps.

WeMacro automatic focus stacking rail can free you from manual works with high efficiency.


Butterfly wing scale test
objective lens :Nikon BDplan 10X and 40X
camera:Sony NEX C3
10X: step length 6 micron
40X: step length 1 micron

Theoretical value when you set 1 micron as a step it will be 0.9375 micron.It will help in high magnification.

 Update info:

1,The black decorative frame on control box is removed since July,2016.Because we found it easy to crack if the box fall on the ground or in very cold circumstance.We hope all parts can be used for quite a long time,so we remove it.If the users find there is crack on the plastic frame,you can easily remove the frame by a Phillips screwdriver.

2,The color of usb cable can be different from the picture above.

3,From Aug 8, 2016,the control box will be bluetooth version.Unless you send us email ask for otg version,otherwise bluetooth version will be sent as default.The bluetooth version can be controlled by any android phone with bluetooth 4.0 and iphone.If you need control by PC,please use USB cable.

4,The holding time of the shutter release had been extended a little to fix pentax’s system trigger problem.

The problem was mentioned in Johan’s review .And the screw-in camera bolt had been changed to shorter one to fix pentax’s threaded hole.
