-====== CHDK scripts for Canon SD1000/IXUS70 ======
-Don't forget you can use zoom to change increment when setting script parameters values (+1, +10, +100, ...).
-Unless said otherwise, these scripts have only been tested on SD1000_IXUS70. If you have tested successfully one of them on other cameras, tell me at crteknologies@free.fr and I will update the descriptions.
-===== Bracketing =====
-==== Night bracketing ====
-When shooting live subject or without a tripod by night, you don't necessarily know if the best way is to use flash or not, and high ISO or not. This script takes successively three shots with low ISO, flash, and high ISO, so that you can choose afterward which one is the best one.

-===== Intervalometers =====
-==== Built-in Intervalometer ====
-Canon SD1000/IXUS70 has a built-in time lapse movie feature. However the interval can only be 1s or 2s. There are time lapse scripts, but they often are too slow for intervals shorter than 1s. Actually the built-in time lapse feature can deal with any interval, given in the property case #265. This script just changes this property.
-''interval-builtin.bas''
-<code sdlbasic>
-rem Author: cyril42e <cyril42@gmail.com>
-rem Camera: SD1000_IXUS70 (and maybe other DIGIC III cameras with built-in time lapse video feature)
-rem Description: Allows custom built-in time-lapse movie interval

-rem set the interval
-set_prop 265 a
-sleep 200
-rem read the interval and display it for verification
-get_prop 265 b
-print "val: ",b
-end
-</code>
-==== Accurate Intervalometer ====
-A lot of intervalometers use the sleep command, but this is not precise and it does not take into account the time necessary to shoot (up to several seconds with metering). This script uses the get_tick_count command so is a lot more reliable.

-==== Continuous Intervalometer ====
-Classic intervalometers cannot be faster than ~2s interval, except built-in intervalometer but which is limited to 640x480 resolution. This script uses the continuous mode to take pictures at any resolution with interval ~0.5 to 0.8s.

-===== Misc =====
-==== Night shot ====
-My Casio S600 has a very good night mode, that uses very long exposure time with low ISO. It allows to take beautiful shots by night with a tripod. Canon SD1000 never set exposure time greater than 1" in automatic mode, and in in manual mode you have to try several time to find the good exposure time. This script automatically computes exposure time so that exposure is correct, and is able to set exposure time greater than 1" (and even greater than 15"). There is also a 2" delay so that the camera is well stabilized on its tripod when the shot is taken. You can adjust exposure with exposure shift/compensation.

-==== Open shutter ====
-This script aims at having the shutter opened the most possible time, eg to shot lightning. Exposition is computed with ''night-shot.bas'' script so that exposure is ok. Dark frame substraction is canceled, but you can shot in RAW, shot one dark frame, and substract afterwards.
