Timelapse Thread : Post Your Own Time Lapse Videos


Ok lets see if people do post videos and experiment more with their cameras and try out Timelapse photography

Nice one. Use a slightly longer shutter speed to blur out the clouds with a ND filter. That will give a smoother feel.

I really liked the way it was put together.

I am not sure if I can use a ND filter with a P&S but I have to get the correct exposure from the script I was running in CHDK these were my settings for this view

Delay (Sec) 25 ( This is duration after each shot is taken)
Limit Tv -414 (Determines the Shutter speed)
Default Sv 480 (Determines the ISO default was around 160 i suppose)
Limit Sv 776 (Max ISO)
Guess mode limit -200 (No Idea what this is )
Slope in guess mode 5 (Again no idea)


Each came as f4, ISO 160 and shutter 1/2500 -- Whats the ideal for a Sunrise or Sunset?

Code:
@title Sunset4
  rem Script to shoot time-lapse videos of sunsets
  rem v. 4, Fbonomi apr 30th 2008
  rem Released under GPL
  @param a Delay (sec)
  @DEFAULT a 10
  @param b Limit Tv 
  @DEFAULT b -414
  rem (-414=20 sec; -384=15 sec; -320=10 sec; -224=5 sec.)
  @param c Default Sv
  @DEFAULT c 480
  rem (480=160)
  @param d Limit Sv 
  @DEFAULT d 776
  rem (776=1250 ISO; 960=5000)
  @param e Guess mode limit
  @DEFAULT e -200
  @param f Slope in guess mode
  @DEFAULT f 5
  print_screen 1
  print "Sunset Time Lapse"
  rem initialize guess mode value
  x=e
  rem get start Tv
  get_tv96 T
  rem picture counter 
  p=1
  :loop
  rem measure luminance and aperture
  press "shoot_half"
  sleep 500
  release "shoot_half"
  get_bv96 B
  get_av96 A
  rem release "shoot_half"
  print "Measured: ",B ,A
  rem resulting Tv would be:
  T=B-A
  T=T+c
  print "Calculated T: ", T
  rem check Tv Values
  if T>e then
   rem normal mode, shoot with calculated Tv and default Sc
   X=T
   Y=c
   print "Mode: Standard"
  else
   rem Guess mode, every shot will be 5/96th steps longer
   x=x-f
   if  x>b then 
    rem we are in dark, but exposure is not too long
    rem normal mode, shoot with guessed Tv and default Sc
    X=x
    Y=c
    print "Mode: Guess"
   else
    rem we are in very dark area, we want to avoid too long exposures
    rem shoot with maximum allowed time (b) and
    rem adjust Sv accordingly
    X=b
    Y=c+b-x  
    rem BUT check we don't go in too high ISO!
    if Y>d then
     Y=d
    endif  
    print "Mode: Guess with High ISO" 
   endif 
  endif
  rem we can now shoot
  sleep 100
  set_sv96 Y
  set_tv96_direct X
  sleep 100
  shoot
  sleep 100
  print "SHOOT ",p,X,Y
  p=p+1
  sleep a*1000
  goto "loop"

Re: Timelapse Thread : Post Your Own Time Lapse Videos

I thought you were using a dslr.

Try reducing the time interval between shots. You will have to shoot a lot more than 50-60 shots though. shutter speed of 1/2 sec or 1/4 sec should be ideal for blurred out clouds. It gives a dreamy like appearance ie if you aer going for such an effect.

No idea whats ideal for sunrise/set. Its mostly trial and error.
How low does the shutter speed on that camera goes ? If your camera has the option to not display image after clicking, then use it. Should help in saving some battery juice. Or try reducing the screen display time to the least possible.

Yeah thats a good idea I would disable the preview... Cause it does take up the battery... And timelapse is mostly trail and error but this script is really nice as it compensates for underexposure when I set the limits... I love Canon for the CHDK can do so much with it beats buying for building a Invervalometer
