Anyone has a (for macro) stacking script optimized for S100. I tried some different scripts , what i´ve found, but it was not the result what i hope.

many thanks for help

I would tend to agree that the two listed on the scripting page are pretty much useless if you don't have the camera the authors used.

http://chdk.wikia.com/wiki/UBASIC/Scripts:_macro_DOFstacker
http://chdk.wikia.com/wiki/UBASIC/Scripts:_yet_another_DOF_stacker

If nobody else posts something better, I'll add it to my list to do a "universal" stacking script that will work on any CHDK camera. Might take me a week or so to get to it though.

thanks for the answer,

i will try these 2 scripts and will write what i get as result or maybe "error messages"
maybe it will help to make better

i was thinking as i tried some scripts, that it is possible to set (M) mode; MF ;then to start the script
then to set (start macro point) -> (now i correct the end of the object by MF)-> now set on script this is my end point.

ok, i will test as first these 2 scripts and give a feedback

Here's the script from the second link ( http://chdk.wikia.com/wiki/UBASIC/Scripts:_yet_another_DOF_stacker ) with the propset values changed to propset4 for the S100 :

You will probably want to read and understand the instructions at that link.

Thanks @waterwings

i've tried the script "yet_another_DOF_stacker" with your changes, but the result is not correctly
after searching i've found a script named "fokus-reihen-dofinfo.lua"
http://forum.chdk-treff.de/viewtopic.php?f=7&t=2510
if script is started u can choos focus begin, focus start and then pressing "set" sometimes it runs great, but sometime u will get the info ( it will make for example 14 pictures ) but runs, make 2 different and one unsharp photo. my question: " must something changed (on script) for using on S100" ?

thanks in advance

Sorry - when I looked at the script a second time I noticed more things that would not work on your S100. I should have posted that as they are not easy to fix.

There are two scripts at the link you posted. The first should run on any camera. The second uses key click to control the camera. There probably need to be changed for the S100 (or any camera other than the one the script was written for).

The first script looks like this with a bit of cleanup :

Code: [Select]

--[[
@title Focus-Stacker-LUA
]]
 
set_console_layout(1, 0, 45, 12) 
press( "shoot_half" )
repeat
    sleep(50)
until get_shooting() == true 

e = get_dofinfo()
f = e.focal_length/100
q = 65535
n = ((e.hyp_dist/(2*e.focus)-e.hyp_dist/(2*q))*e.focus)/((10*e.focus-f)/10)+1

release("shoot_half") 
repeat
    sleep(50)
until get_shooting() == false

print ( "Start focus: " ..  e.focus ) 
print ( "Photos: " ..  n+1 .. ", F" .. e.aperture/1000 .. ", " .. e.focal_length/1000 .. "mm" ) 
print ( " " ) 
sleep (1000)
print ( "Focus " .. "Target Focus " ..  "DoF-Target" ) 

shoot ()

for i=1,n do
    h = e.focus+e.dof
    p = e.dof
    focus = e.focus
    if h > e.focus then
      set_focus (h)
      shoot ()
    end
    e = get_dofinfo()
    focusdiff = e.focus-focus
    if i==n and e.focus_valid==false then 
      set_focus (65535)
      shoot ()
      e = get_dofinfo()
      print ( "" .. focus .. "  " .. h .. "-".. e.focus .. "  " .. p .. "-" .. focusdiff ) 
    end
    print ( "" .. focus .. "  " .. h .. "-".. e.focus .. "  " .. p .. "-" .. focusdiff )
end

I'll take a look at the second one when I get a few minutes.

Looking at all these script, with fancy hyperfocal and depth of field calculations, I can't help but wonder if it would not be easier to just write a simple script with user defined parameters to set the initial focus (in mm), the size of each focus step and the number of steps ?

I have not used focus stacking software on my PC (yet) so I'm not really sure what the requirements are for the pictures used to create the stack. Feedback on that would be welcome.

hi,

i've checked these script's, but it is not so the result what i would have.

another question (digital zoom) - on S100 is the max. 20x
possible to expand that digital zoom with chdk ?

thanks for answers
