Best/coolest chdk features?

I'm heading on vacation to Hawaii next week and just wondering what some people feel are the coolest chdk features that I should take advantage of on my trip.  I'm travelling with my wife and two young daughters.  Is there a waterproof chdk feature?? :P

There's a (float) feature, but it doesn't work in scripts.

The coolest feature is the ability to run scripts, and particularly Lua scripts. For your vacation, try setting the camera up on a mini tripod pointing at the kids in the pool, and run a script that takes shots every 5 seconds or so.

My favorite script is one that simply holds the shutter button down in continuous mode, and takes around 2 shots per second. Point the camera at the pool, and have everyone jump in. One picture is bound to be a good one.

Code: (lua) [Select]
--[[
@title Clapse
--]]
--MUST BE IN CONTINUOUS MODE
print("Holding shoot_full")
print("Press <menu> to exit")
sleep(5000) -- time to get in front of the camera
press("shoot_full") -- continuous mode
repeat
  sleep(100)
until is_pressed("menu")

You seem to be getting a little preoccupied with two fps, it is no 'big deal'.

Why not try three or four fps instead (with movie mode fps hack) ?

Actually, I'm more preoccupied with one fps or less in continuous mode. By putting a delay in capt_seq_hook_set_nr(), I'm getting very precise intervals. Combined with shot metering for adjusting exposure, it achieves the "holy grail" of time lapse. That is, going from day to night smoothly, without flickering.

That's a great idea. But I thought the movie mode thing just changed the fps in the file header. I've played around with the "miniature mode", which has several fps settings, but it also blurs the edges. Is there a hack that actually changes the movie shooting frame rate? Tell me more.

You need to be able to disable sound, easier said than done (apart from certain movie modes where there is no sound).

Good luck, let us know how you get on.

This is hardly a feature casual user could try on their vacation :-[

IMO, the most useful feature for casual vacation shootings are bracketing, zebra and / or histogram. Not "cool" perhaps, but helpful to get more good shots. If your camera has limited manual controls, then overrides may be useful too.

Depending on what on your interests and location, there might also be opportunities to use motion detection or time lapse scripts.

As always, the thing that matters most is the nut behind the viewfinder ;)
Don't forget what the H stands for.

I figured the kids might want to do a little light hacking by the side of the pool.

Yes, but with a time lapse program, instead of one bad picture, you can take 1,000 bad pictures!
