MACRO PP : Focus Stack using Different Pictures

I am doing this ad-hoc (have plenty of topic are in the list). This is similar to another topic discuss in

http://liewwk-macro.blogspot.com/2009/01/how-i-increase-my-macro-picture-dof.html

in two situations as below

1. what if the bug move then how to apply the method apply above
2. a good composition pictures but not get main object focus... how ? delete it ?

so this topic help me to "rescue" above 2 problems

it is simple as step by step below
1. as this shoot when windy day + handheld + keep moving fly so the composition look ok but main object not focus as below


100% Zoom


2. I have a similar fly (similar angle is most important) shoot 1-2 weeks ago which got better eye focus but magnification are different


3. open the main composition picture as base


4. open the other "eye" picture and duplicate over the previous layer


then this layer will over write the main layer


5. set the opacity to 20-30%


then you will get this


look for "transform control" it different for CS3 & CS4 (this screen shot form CS4 and CS3 can get from "Edit" menu")


6. change the size of the picture if magnification different


-rotate it if the angle is not correct


7. adjust back opacity to 100%


8. add layer mask and make it invert



while invert of the layer mask, you will see



9. select a brush with "white" color by selection


10. zoom in to the eye


11. use smaller brush



12. brush out the area you interest , for this is head + eye


zoom out then you will see this


13. save the picture, let see the exif


14. easily verify by zoom 100%



so see the different ?

stack


original



some of you will say WOW, some will say "You Cheating" ....but this is rule of digital so we this is good to know :D

so have fun :D ...

This isn't strictly speaking 'stacking.' It's superimposing.

Brialliant idea. I never think about it before. Normally I do the same thing on human potrait only.
