So i should use minimum shutter between 1/500 or 1/1000 and iso above 100 but below 1000. Correct?
Start with 1/1000 and let the max ISO1 be 800 and max ISO2 be 1600 and see how it looks ?

Ok!

And should i use this setup for sunny days and cloudy days? And the F-Stop? low = 2.8, target = 4.0, max = 8.0?
I'm travelling this week so doing this all from memory via a mobile phone.  Does your camera actually even have a user adjustable aperture?  If not, the script will just ignore those settings.

It have only a ND Filter, so those settings wont work!

And btw in the Focus @ infinity mode i choose the none option, right?
If it works for you (and it does for most people) then the setting focus at infinity to MF is probably best.  Gives the camera one less thing to do between shots.

Update :  one of the common causes of blurr is vibrations on the UAV platform.  You have some good pix so that's probably not an issue.  Also,  it seems that turning off image stablization (if your camera allows that) is may actually a good idea - YMMV.

How does it work that MF thing?
And regarding the vibration inst a problem, i got very sharp photos when there is plenty of sun!
And yes i can turn off the image stabilization!

Thank you so much man. Tomorrow i share the results!

The MF and AFL settings basically tell the camera not to autofocus.  The script gives it a command to just set the focus at infinity.   This saves time as the focus should be at infinity and the camera does not need to figure that out based on a moving image off in the distance.

Either of the setting works well on most cameras if you are using CHDK release 1.3.0.

I have the 1.2.0 version.

Maybe that why that when i tried to use the AFL the result was total unfocus in all batch of photos (see attch)

Does it worth to upgrade to 1.3.0?


Ps. since the interval is 3s and i start to take photos since altitude is 0m to 100m maybe this option inst valid for me.

1.3.0. is what I use to test the script.  You'll need it for MF setting.   Go for it.

And on these little cameres,  infinity starts at about 30' due to their large depth of field.  So I'd advise using it if it works for you.

ok! gonna upgrade ASAP.

And one final question i have another sx260 but with a NIR filter should i use the same settings? Or do i need another settings?

I'm guessing the same settings. One script user reported better success with his IR modded camera than his stock unit.

Make sure you have logging to the SD card enabled. If things don't turn out well those log files can be a big help in understanding what!

Finally got around to testing the latest TLAPTEST v3 script with no logging. 

My apologies for taking so long. 

I used the same SD card I had been using for all the previous test. In the video there does not seem to be the time shift I have been previously experiencing.  Unfortunately it was a cloudless sky and the clouds moving was the easiest way to see the shift in the interval time, but the shadows moving and the traffic seems to be consistent.  There is some flicker in the exposure.  It is not the huge jumps I have seen in some of my other attempts but still there.  This might be down to the limitations of the camera since it is one without an iris in the lens so if there is any breathing in the focus (the lens moving in and out) there might be subtle changes in the exposure.
