"May, 2012 timefocus.bas / \"SHUTTER & FOCUS STACKING\" is a combined depth-of-field (focus) stacking and exposure bracketing script for CHDK. Written for and tested on the Powershot S3IS, it should be portable to other models by changing the test-values of only two lines which interpret the Mode Switch position. Before entering mode you should: \n* Put the Mode switch in either Manual or Av mode, depending on how picky you want to be about choosing your center exposure value. \n* Choose an f-stop (Av). High numbers will give you maximum depth of field in a hurry. If you want to focus only on a certain foreground range, low numbers will leave the background more blurred, which may help your subject stand out more. \n* Manually focus on the closest point you want to be sharp. \n* Confirm that you're in single-frame mode, not Continuous or Delay. Note: this script's strength in exposure bracket is its versatility. Instead of being limited to only 3 exposure steps, you can have up to 9, and the steps can be as far apart as 3 full stops. But if you don't need that stuff, using your camera's own bracketing system will be faster. Set up the bracket spacingin the camer's menus (accessed via the FUNC button in the S3). Where you tell this script how many exposure steps you want, enter 1 to allow the camera's native bracketing to do the job. \n* Turn off Preview. This script may take a hundred or more shots, and you don't need to wait 2 extra seconds after each one. \n* Mount the camera on a tripod, or at least set it on a solid surface. Choose your script shoot delay based on whether you have a remote for your camera. If you do, you probably don't need any delay; if not, a couple of seconds will give time for any vibrations to end after you take your finger off the shutter button."@en .
