yet another personal build (archive)

Hi Jucifer, thanks for the reply. fbonomi inquired about the trouble I'm having over at

Bracketing series (for example for timelapse HDR)

this thread, so I have some info there.  Basically, after 90 shots are taken, get_exp_count *both* jumps (ahead by 16,387 or thereabouts) *and* freezes (doesn't increase as the shots are taken).


I'll see if the first aid would work.

[rawhead]

All right, here's the result.  I simply used

Code: [Select]

until z>=y

this instead, and as you'd expect, the 19th cycle (i.e., the 91st shot) ended in just one shot, because z was way larger than y.  Good news is that with the 20th cycle, the script continued to go as expected, with both z and y reset to the much higher number.


This is workable for me, because I know that all I need to do is to remove every 91st shot before I batch process the images.


In the mean time, I would greatly appreciate it if you can look into the issue.  I will also try your script and see what happens, and get back to you.

Little update. It turns out the problematic shot *isn't* always the 91st shot.

With the band-aided script, I ran a test of 100 cycles of 5 shot brackets, and the following were the problem areas (i.e., the Solo shot taken whenever Z went way high):

Shot #86, #187, #288, and #384


So at first it looked like the problem was going to be every 100 shots after the first one, but the 4th one threw that off as well.  I don't know what, if any, the pattern is here...

updated the e-build

changelog for 080604:
- get_exp_count now returns the (up to) 4-digit number as in the last file saved by cam. This behavior may be pretty much final, unless a better counter is found for every cam. NOTE: when scripting using get_exp_count, the possible counter reset should be taken into account.
(might be something along these lines:)

Code: [Select]

T=get_exp_count+N
if T>9999 then T=T-9999
press "shoot_half"
press "shoot_full"
do
until get_exp_count=T
release "shoot_full"

I noticed a dramatic speed decrease when taking shots in continuous mode with scripts, especially uBASIC. I'll have to look into this.

K, Jucifer,

Just tried running a 300 cycle test and it worked beautifully.  Took exactly 900 photos without skipping a beat.  The only change I'd need to make is the counter check for >9999.


THANK YOU SO MUCH!

Hi "Jucifox" 
found your new branch (nice synonym) and asked myself whether LUA  is on the way to wonderland now...will there come some news reffering to this (i hope so) ?

[Jucifer]

Phox created a new branch for us.
It will become the ultimate chdk build.



But seriously, it will contain lots of tweaks and mods floating around.
Lua should definitely be one of those.

[PhyrePhoX]

yeah we probably are going to open a new thread about this, we dont have a real "strategy" as of now - yet. we will let you know, thats for sure.

[pethead]

How do I own branch on your SVN with my timestamp feature? or join to your branch?

[Jucifer]

I guess your timestamp feature could be included in our branch. Can you attach the patch (somew)here?

[Jucifer]

(the speed decrease was probably somehow related to chdk.cfg)

updated

[lukg]

Moved to the other thread!
