The RAW Timelapse Tutorial - INTRODUCTION
***NOTE: All opinions & perspectives shared come from my experience as a shooter and may not be the best way of doing things. I am simply sharing MY WORKFLOW when both capturing and processing RAW time-lapses similar to the ones seen in the INTRODUCTORY video below***.
Target Audience
The target audience of this series will be the independent filmmaker who is open to learn. In the series, I hope to give a thorough breakdown of how to shoot RAW time-lapses. There is no perfect formula to get incredible shots other than practice, practice & more practice. These shorts will simply give you a look at how I approach shooting time-lapses. Comments and recommendations for future videos are encouraged.
This series is a work in progress and will continue to evolve as I learn more. Below you can find the current content breakdown:
1: Introduction
This video will introduce the series as well as showcase the types of shots that will be present in the time-lapse series.
2: Kit Breakdown / Software & Hardware Solutions – Introduction
In this video, I will give a quick preview of what equipment I use when shooting time-lapses.
3. A Closer Look at my ‘Tool Kit’
In this section, I will look closer at my ‘go to’ equipment and also break down a few different kit configurations depending on shot requirements as well as shooting conditions.
4. PRE-PRODUCTION — (Story, Scouting & Scheduling)
Pre-production is by far the most important part of the process for not only time-lapse photography but filmmaking as a whole. By being prepared from the beginning and by having a well laid out plan, production & post-production will ALWAYS go way smoother. There are a few specific areas that I will be investigating as part of the pre-production phase.
- Searching for Locations.
- Prepping Gear.
- Shot Lists.
5. PRODUCTION
This section will be the most extensive and will encompass a wide array of possible time-lapse setups. For a list of the current tutorials to be covered in the series, please see below:
- Camera Settings/Modes: Understanding the Basic Functions of a DSLR
- Static Time-lapses
- Motion Controlled Time-lapses
- Day to Night Time-lapses
- Astro Time-lapses
- HDR Time-lapses
- Walking Time-lapses
- Bulb Ramping
6. POST PRODUCTION
For this section, I will be covering a few different methods for processing the time-lapses as well as cover some of the ways in which to remove flicker from your time-lapses. I will also be focusing on a few composting techniques.
Some of the programs/codecs I will be covering include:
- LR Timelapse, Lightroom, After Effects, Photoshop, Premiere, FCP 7, Quicktime 7, GB Deflicker, CHV Time Collection, ProRes vs CineForm, Photomatrix, GBS Timelapse & more.
NOTE: I will be spending a substantial amount of time discussing how to remove flicker using various programs as it is a highly requested topic.
7. Distribution: An Expanding Market Opportunity
The demand for online content is increasing. Grants for web series are becoming available. Discounts that used to exist for online content, such as discounted actor rates, are quickly disappearing as many are seeing the added value in online content. Crowd funding is also becoming a viable option for funding. With this shift, it is key to create an online presence — and get your work seen.
Paying it Forward
The gap between low quality and high quality video is quickly closing and this quality content is becoming available at a fraction of the price. It is becoming even more important to find ways to stand out from the crowd.
Now the main reason I am asking anyone that learns from the tutorials to either post their work or post something they learn along the way is because of the impact this work could have upon someone else. By posting your content online, you may be posting content that a viewer can relate to. You may even inspire someone or speak to them on a deeper level that could inevitably cause a life altering event. Who knows?!?
With this new market that is emerging, many people now have access and it is becoming even more important to find your niche. There are a few things you can do to stand out. Do work that relates to personal experiences. Continue to work hard and be passionate about the work you do — no matter what you are working on. Do the best possible job you can do on EVERY job. If you continually grow and work hard, good things will happen. It doesn’t take much to push yourself as a filmmaker. I’ve found that it is actually harder to be complacent!
Conclusion
Although only a quick look, the above post breaks down what I will be covering in the tutorials. If there is anything you would like to see added to the list or any advice on how you would like the series to be approached, please share in the comment section below!
NOTE: All videos will be available on The RAW Timelapse group. To either share your experiences or work, please join. https://vimeo.com/groups/payitforward Thanks!

din drones tutorial
In this tutorial you will learn how to:
* Create drones at any pitch & volume
* Move drones around invidually or in large groups
* Change the drone waveform to change the timbre of the sound of all drones.
* Shift the key of the scale over bpm and thereby shift the pitch of the drone mass for interesting fx.
Index:
00:42 - Press 1 to goto microtonal keyboard. a, d to scroll left & right. w, s to scroll up and down
01:18 - Press SPACE to mute the lead voice to work with just drones.
01:40 - press BACKSPACE to clear console, press TAB to enter command mode. press ` to fold console.
02:00 - press i to toggle on information display. mouse cursor shows current pitch & volume.
03:05 - press q to create a drone.
03:47 - press . to increase drone master volume. press , to reduce. press / to mute.
04:58 - din is a 3 octave instrument by default. change the number of octaves using the num-octaves command. the current octave number is marked on the middle of every tone range eg., 2/7 ie 2nd octave of 7 octaves. also see http://dinisnoise.org/num-octaves/
06:00 - press e inside a drone to select that drone. now just move mouse to move that drone.
06:55 - not clicking! pressing q :)
07:43 - press q and hold down to spray drones.
08:20 - click and drag to select a bunch of drones. press c to delete the selected drones. or you could press e to move the bunch with the mouse.
09:30 - dont want drones to suddenly jump up in volume? create at 0 level. select the bunch and press e to move.
10:50 - you can create n number of drones. but there is only 1 oscillator ie waveform. press 8 to edit the drone waveform. q and e to zoom. w,a,s,d to pan.
11:22 - x to snap x, y to snap y, b to snap x & y, n to disable snapping.
11:50 - to move a vertex or tangent on the curve press f inside a diamond (handle?) and just move the mouse. no need to click & drag. multi handed input is faster at live performance. trust me :)
13:05 - press space to apply the output curve of sine harmonic composer (see relevant video) to the waveform. press ' and \ (check your keyboard layout) to increase or decrease the samples of the sine harmonic composer.
13:33 - press 9 and 0 to scroll thru the waveform library.
13:40 - press LSHIFT + t to mirror the whole curve. in video, this reverses the reversed phase bezier sine waveform.
13:51 - press F1 for help on curve editor. use insert & delete keys to scroll console.
14:05 - mouse capture. F7 to start/end capture. F8 assigns capture to vertex/tangent under mouse cursor. F9 to detach mouse capture from vertex/tangent under mouse cursor.
15:20 - sine waveform composer. press g inside magenta levels to add/modify harmonic level. c to clear. h to toggle.
17:48 - LSHIFT + mouse move to compact the tone range under cursor. LCTRL + m to apply size to all ranges. this helps see the entire tone range of din when drones are extremely spaced out.
18:20 - aliasing at very high frequencies.
18:47 - u can expand ranges too using 17:48.
19:27 - for snapping drones to notes set snap_drones variable:
;# snapping drones to notes
set-var snap_drones 1 ;# long form
sv sd 1 ;# short form
sv sd 0 ;# snapping is off
see http://dinisnoise.org/set-var/ for list of din variables.
22:35 - get-drone command for querying drones.
get-drone num-drones OR
get-drone n
returns number of drones.
get-drone selected OR
get-drone s
will return list of selected drones.
see http://dinisnoise.org/get-drone/
23:30 - use set-drone command to set volume of a list of drones.
;# sets drones 7 and 8 to 0 and 1
set-drone volume {7 8} 0
set-drone volume {7 8} 1
see http://dinisnoise.org/set-drone/
25:45 - press z and x to octave shift the key of the scale. since drones are laid out on the tone ranges determined by the current key & scale, as the key shifts, the pitch of the notes of the scale shifts, the pitch of the drones shift too. use set-bpm command to control the rate at which this shift happens:
;# 1 beat per minute
set-bpm os 1
see http://dinisnoise.org/set-bpm/
26:50 YUCK! SORRY! TOO LATE. TOO LONG & TOO TIRED. IGNORE. RETRY. FAIL!
press 7 to goto octave shift curve editor.

Martha Cotton at IIT Design Research Conference 2010
Accidents and Plans: A few good tools for collaboration
Once upon a time, marketers saw truth mostly in numbers. But, as this conference will explore, there have been some key shifts in the last 10 or so years: Design Research has broken out of its niche status and quantitative research has been stripped of its compulsory status. Design research has moved to the mainstream; quantitative research has become but one of many tools for decision making.
“Truth” about consumers is now found in many ways: stories, photos, video, quotes, anecdotes, sketches, conceptual frameworks, and more. Accompanying this shift our community has developed, and will continue to develop, more useful and interesting ways to gather qualitative data.
This talk will explore a variety of compelling ways we are now able to gather qualitative data. We will also expand the context to explore ways other phases in the qualitative research lifecycle can be done in more rich and effective ways including participant recruiting, analysis, and accessing project data over time.

BY FRANKLYN WEPNER SEPTEMBER 1, 2006
HOW I WORK: GESTALT DREAMWORK AS THEATER AND PROPHECY
GESTALT DREAM WORK AS PREPARATION FOR PERFORMING
Since 1975 I have been using Gestalt work on awareness, dreams and personal relationships as a way to train and direct performers. The basic principle is simple. I use the Gestalt work to peel the onion of layer after layer of social cliches, ego games and unfinished personal business, and then I do the reverse process reconstituting the onion in the form of characters or other artist structures. The existential message of the dream becomes the superobjective or action of the tragedy, and then I build up the way the performer handles the characters and the plot around that.
My usual procedure is to begin the training with three Gestalt sessions, one on one. The first session, two hours long, deals with the three zones of awareness. During the first hour I simply let him relate what he aware of, since I want to know how he operates before I start meddling with his life. This is important since overall during the Gestalt sessions we are peeling the onion of cliches and games to get to authentic action, and later we will need all of those layers to rebuild the onion as characters involved in the unfolding action of a drama. We need his cliche and game layers for the beginning of the action in Act One as much as we need his authentic action at the end of the dramatic action for Acts Four and Five of a tragic drama.
During the second hour of the first Gestalt session on awareness I attempt to guide him towards a balance of the zones of awareness: outer zone awareness of the environment, inner zone awareness of his body, and fantasy zone awareness of his daydreams. The second and third Gestalt sessions are each three hours long, and each is a typical Gestalt dreamwork session as presented by Fritz Perls in Gestalt Therapy Verbatim. The performer tells the dream in the here and now, identifies with (play acts) several of the main images of the dream in dialogues with each other, and experiences the rhythm of contact and withdrawal. That is to say, after each major dialogue of polarized sides of himself (the contact part) he is instructed to close his eyes, enter his body awareness and daydream (the withdrawal phase of the rhythm).
Since my goal is theater as well as healing, whenever possible during the Gestalt dreamwork I encourage lots of expression using sound and movements. I work with a palette of about 200 different types of recorded musical excerpts, and whenever appropriate I ask him if that image or emotional state were part of a movie what sort of music might be the sound track. Then I find something close to that in my palette of musical colors and ask him to express the mood using the music along with his vocalizing and expressive movements. While he is doing the entire session I spend most of my time jotting down near verbatim notes and making stick figures of his poses and movements, since later in the work I will feed all this back to him and encourage him to explore using it as creative material for acting, dance or whatever his medium is. Taping the session is less useful, since then I would need to spend too much time replaying the tapes. Taking notes live forces me to sort out the wheat from the chaff very efficiently, even at the cost of not observing or notating every detail.
WORKING OUT FROM YOUR CENTERS
After the three introductory one on one Gestalt sessions, session number four is for feedback and discussion of the results. I show him in my notes and diagrams all of the stages of competed and uncompleted actions, and together we search for characters in the theater literature that have similar patterns of action. Is he a Hamlet type, or an Oedipus type, for example? In contrast to the usual practice in acting classes, his first acting assignment probably will be a monologue from a serious tragedy, since I want him to begin with a dramatic action with which he can identify totally. In this process he is using his major Gestalt moments as what Michael Chekhov in his book "To The Actor" labels "psychological gestures". Perls calls them the "essences" of a patient's personality, or we can say he is working from his "centers", stretching those sounds, moves and psychological motivations in as many creative directions as he can. I monitor closely to be sure he is not faking it, the way most actors end up doing since they do not have the centers to begin with.
Before the performer begins working with others doing improvs and scenework, there is an important transitional stage in the work in which I help him get comfortable using his very personal Gestalt material freely as creative material. He needs to shift from seeing himself as a patient to enjoying the role of an artist of the
