Time Lapse Photography

Great fun, very worthwhile but a lot of work!

Time Lapse Photography

Time lapse photography is when you take a series of photographs at intervals of more or less the same exposure and frame rate. You then stitch them together to make a short video. For example, you have probably seen footage of flowers opening super quickly, clouds flying across the sky or ice melting really fast?

This can be great fun and quite challenging so why not give it a go!

You will need a tripod to keep the camera in exactly the same position throughout, unless you are really creative. It needs to be very stable. You will need enough memory on your card to hold a large number of images. Also, you will need to work out the timings for your shoot.

Final length of time lapse

How long do you want the finished time lapse photography footage to be?

  • check
    5 seconds?
  • check
    30 seconds?
  • check
    A minute?

Anything too long will not look right or could bore the viewer. Time lapse is meant to be short and sweet and show a world we generally never get to see other than in super slow, real time. Let's say a flower takes a full day to open and you want to show this in around 30 seconds of footage.

If you took one frame/photo per second, that would give you:

  • check
    60 frames per minute (1 frame x 60 seconds)
  • check
    3600 frames per hour (60 frames x 60 minutes)
  • check
    86400 frames per 24 hour day (3600 frames x 24 hours)

At 30 frames per second playback, that would give you 48 minutes of footage. That is 86400 frames divided by 30fps (frames per second) = 2880 seconds = 48 minutes). Way too long unless you then speeded it up in post processing. You would have 86400 images to place in a timeline.

You could playback at 60 frames per second giving you 24 minutes…but that is still too long.

Take less photos

For a time lapse photography sequence of a flower opening over a 24 hour period, 1 shot per second is far too much. How much movement do you see with the naked eye in just a second? Not a lot!

Try one frame per minute, that will give you:

  • check
    60 frames per hour (1 x 60)
  • check
    1440 frames per 24 hour day (60 x 24)

Much more respectable and this, when played back at 30 frames per second, would give you 48 seconds of footage. Play it back at 60 frames per second and you have 24 seconds of footage. This would show the flower opening in its entirety. 1440 images in a timeline is much more manageable too!

Time Lapse Photography - Lighting

Unless you live in the far northern hemisphere and the lighting is constant, you will have problems as darkness falls when shooting outside. You may want to show night into day and vice versa*. However, a much more practical and pleasing way to do this is under man-made lighting conditions.

*NOTE: This is totally doable but only with some specialised software that I also use. Check out LR Timelapse and thank me later ; )

Set the flower up in a spare room and use some form of continuous lighting. Turn off all other lights and black out the windows. For one this will give a constant and correct exposure and the warmth from the light may even speed up the opening.

Once the flower and lights are set up, set your camera to its desired settings with aperture and shutter speed. Make sure the batteries are fully charged. Do you want deep or shallow depth of field? Try and keep the ISO as low as possible for quality. Don’t worry about long exposures of a second or so if that is all you can get. There will be virtually no movement in the room during that second.

Now, you will need to take a photo every minute for the next 24 hours which can be a chore. We all need sleep! A quick and easy way to do this is to use a timer release for your camera.

Timer releases

I use the Canon TC80N3 Timer Remote Control on my 5D Mark IV and love it. However, it is limited to just 99 frames meaning you will have to come back and press "start" again every 99 frames (or every one hour and 39 minutes if shooting one frame per minute…a bit of a pain for longer time lapse sequences)! Luckily, the Canon EOS 5D Mark IV and other modern cameras have built in intervalometers.

Alternatively, third party manufacturers make these for all makes and models of Digital SLR. Cameras such as Pentax, Canon, Nikon, Olympus, Sony etc and for a very reasonable price. These ones can shoot up to 399 shots and more.

You can set these to take images at any interval you wish and for as many frames as you wish. This is depending on the limits of each model. Once set up and running you can go about your business knowing that your camera is doing all that work for you as the timer takes the shots!

I need to get out and do more of this myself as it can be great fun and the possibilities are endless.

You can even sell the footage as stock too

The following video has a few time lapse sequences using special equipment and software. For the moving time lapses, I use the Rhino Ultimate Slider which is simply amazing. In fact, I am about to use this kit for a Netflix documentary soon (2018). See at 1m 34s and later in the video here:

Again, the night to day and day to night time lapses were done using LRTimelapse. Genius software!

You can see more day to night time lapses plus a "hyper-lapse" sequence in my portfolio video here:

Lessons learned were not to leave autofocus on as at some point the focus shifted to a spec on the window, luckily the depth of field was pretty good. Secondly, it was hard to know whether to use auto exposure or manual. I used manual but in hindsight, auto would have been better in this instance.

My first ever "moving" time lapse

This one was a little more tricky and taken in the days before Rhino Sliders and LRTimelapse. I wanted movement when shooting a time lapse with my old Go Pro so I bought an egg timer! As well as taking one shot per second, I also put the Go Pro on top of the revolving timer so that I would get a pan effect in the final output.

Think of some ideas for your own time lapse photography and write them down. Also write down how you intend to shoot whatever it is you want to shoot. Make a detailed plan and just do it. Time lapse photography is great fun but takes a lot of practice to get it right!
