Youve probably stumbled upon an incredible work of time lapse where you just couldnt get the images and the feelings out of your head. Possibly you are fascinated by nature and the slow changes that occur over a period of time. A flower blooming, a sunset or a moonrise. Maybe it was a construction project or a cityscape at night, full of activity and production. Im a big fan of time lapse photography and I love seeing the amazing work that people create from all over the world. I thought Id share a few tips Ive learned over the years as well as touch on the basics for new and intermediate DSLR photographers who might want to try time lapse. Since there have been some great written introductions here on DPS I decided to use a few videos and screenshots from the e.

Book Time Lapse Photography A Complete Introduction currently 2. We know that time lapse is all about the capture of change in a way that we cant normally see. But whats really going on in the background Lets take a closer look What is Time lapse Photography Time lapse photography is a cinematography technique whereby the frequency at which film frames are captured aka the frame rate is much lower than that which will be used to play the sequence back. Put simply We are manipulating time. Objects and events that would normally take several minutes, days, or even months can be viewed to completion in seconds having been sped up by factors of tens to millions. The best way to get a greater feel for the power of time lapse is to watch a few. Now I know you have seen some before, especially if you watch reality TV but Im not really talking about those short clips between tribal counsel elimination decisions, it can go a little deeper if we let it. What I am talking about are the compilations that really grab your attention and make you think about the world around you. The ones that give you a better understanding about how nature changes and cities work. Timelapse The City Limits from Dominic on Vimeo. Its so much more than a gee whiz editing effect. It can be used to tell a story. The Gear You Need To Tell Your Own Time lapse Story Chances are if youve been shooting with a DSLR camera you probably have just about everything you need to get started in time lapse photography. Phew Here are the minimum gear requirements for a new shooter. Since a stable shooting platform of anykind is so important I wanted to include a page on tripod stability. If you are really looking to push the limits of your creativity well introduce some advanced gear to build and buy in the e. Book and I wanted to be sure to include an example video a little later in this post. Balancing Time lapse Image Settings Size, Quality, Space and Speed. Size, quality, space and speed Its nothing new if youve worked with digital images before but with time lapse sequences poor planning can quickly cut a scene too short or leave you with a blinking Card Full message just as the sun peaks out over the mountains. Theres a lot to discuss here but if I were to boil all this down into a simple recommendation it would be this Shoot in the highest resolution actual image dimension RAW format your card capacity, camera write speed and time lapse planning will allow. RAW images will allow for non destructive tweaking and correcting in post production using standard or transitional editing. Processing For Visual Artists Pdf File' title='Processing For Visual Artists Pdf File' />High resolution images will provide the freedom to crop as well as program in movement by panning, tilting or zooming into a sequence in post. Heres a page to help you gauge the file size implications of your decision The Basics of Shooting Time lapse. I cant stress this enough If you are new to time lapse, review these basics then get out there and play. Your first few tests should focus more on experimenting with different changing subjects and a little less stress about creating a technically perfect rendered sequence theres plenty of time for that later. Get a few fun tests under your belt and the time lapse bug is sure to carry you through to the next steps. After youve had a chance to survey the basics, well walk through some specific scenarios and advanced topics. This section is obviously pretty big and pretty important but if I had to pull out only a few pages on the fundamentals of shooting DSLR time lapse it would be this Composition, a. Time to polish your crystal ball, look into the future and find interesting change and a dynamic scene. Select a time lapse interval to balance speed and flow. Control your exposure to minimize and eliminate time lapse flicker. The best way to explain this is a short video. The most important concept here is full manual control. Now no worries if you are a little rusty on manual exposure. How to prevent ticklabels from having an offset The default formatter will use an offset to reduce the length of the ticklabels. To turn this feature off on a per. PeStudio is a portable tool that performs malware assessments on executable files, since the target file is never launched during the course of the investigation you. Take a look at this time lapse exposure triangle as a refresher and be sure to lean on some other great DPS posts to hone in your skills. The second most important exposure consideration is motion blur. Since our time lapse images are played back to back very rapidly, the slight blurring in each individual photo blends together creating an added smoothness to the entire sequence. As a rule of thumb, try to keep your shutter speed under 11. In order to get such a low shutter speed in daylight conditions we will probably need to use an ND filter Like sunglasses for your camera, neutral density or ND filters reduce the intensity of light without altering its color. Creating the Time lapse. Compiling the images is where it all pays off. Creating your time lapse movie from hundreds of still images isnt very complicated, however approaching the rendering process without a set workflow can make things seem more complex than they actually are. I assure you once its built and youve run through it a few times youll be able to cruise through the time lapse process. Here is the basic process in two nutshells the first being the basic process. Unfortunately I dont have enough space in this post to launch into each workflow specifically but a quick time lapse rendering tutorial search on YoutubeVimeo or a glance through Chapter 5 for your specific software preference should take you the rest of the way. Where to go from hereYou now have a firm understanding of the basics of time lapse shooting, flicker prevention, and rendering. I encourage you to get out there and practice. Experience will be your best guide and the best way to gain experience is to test the limits of your understanding. In Chapter 6 of Time lapse Photography A Compete Introduction Ive organized four challenges to test our planning, shooting, and processing skills. It is my hope these scenarios spark questions and a fascination on how these techniques can be applied to different situations. We attempt An Astrolapse. The Time lapse Holy Grail. High Dynamic Range HDR Time lapse. Well also take the first step in considering how motion control devices can be used to create amazing time lapse effects. Heres another example of some of the amzing work thats been done combining advanced time lapse motion and exposure control. DEUS EX HOMINE San Francisco 3. D Moco Time lapse by Golden Gate 3. D GG3.

With all this information under your belt are you ready to head out and capture the changing world, or is there still a little skepticism inside that you can really create something great Eric Warren of Matadornetwork. Do you think time lapse should be left to the prosPros are the guys you call when you want to put a time lapse in your car commercial. And while we tend to put pros up on a pedestal, they are often bogged down by their clients needs. Most commercial advertising doesnt push the envelope of an art form. That job often falls to the independent artists, building their own equipment, and often not giving a rats ass about whether their work is going to sell. How To Matplotlib 2.

Larsen The American Statistician Vol. No. 1, Feb., 1. 97. However, bar plots with error bars are still the common standard in most scientific literature, and thus, the interpretation of box plots can be challenging for the unfamiliar reader. The figure below illustrates the different visual features of a box plot. Violin plots are closely related to box plots but add useful information such as the distribution of the sample data density trace. Violin plots were added in Matplotlib 1.
