Assignment 13 Night Photography

Go outside between dusk and dawn using whatever existing light is available recognizing its color and mood, make a photograph that is surprising by what it reveals.

 Post a photograph that you like the lighting and that you wish to emulate. Sketch out how you think it was lit. You can use this file to make your sketch: http://www.diyphotography.net/lighting-diagrams

Lesson 13 Night Photography

 We used the Digital Multi-Function Trigger to capture a popping balloon at slighting different times by varying the distance of the Trigger to the balloon.

We looked at the work of 3 photographers whose vision of the night is unique.

Assignment 12 Stop Action

Photograph something in action that you can’t see with the naked eye.  Use a camera and flash combination on manual attached to the hot shoe or the off camera cord.  The flash should be dialed down to 1/16 power or less in order to achieve a flash duration of 1/10,000 or less.  Examples are splashing water or stopping a fans blades with a ribbon attached.  I want these images super sharp with no blurs. 

Lesson 12 Flash Duration and Syncing

Here is a good article about HyperSync by Rob Galbraith from 2009

Using the PocketWizard Plus III and a shutter speed highert than 1/160 results in second curtain cutoff.

Using the PocketWizard Flex TT5 and the setting HyperSync, we were able to sync up to 1/8000 using the Profoto 2400 Pack at full power and a flash duration of 1/320

Using the High Speed Sync setting on the Canon Speedlite 600EX-RT, we were able to sync up to 1/8000 

The HiViz SK2 Sound Trigger is an inexpensive way  to set off a strobe with sound.

An explanation of Paul C Buff Einstein strobe to show the two different ways strobe manufactures control the flash output and what that has to do with stopping power and color temperature.

PocketWizard's explanation of HyperSync and HighSpeed Sync

Another blog that we looked at about using the PocketWizard FlexTT5 on High Speed Sync (HSS) mode you could sync our studio strobes at a 1/8,000 sec.

Assignment 11 Light Painting

1. Make a photograph using flash as a painting tool.

2. Make a photograph using a continuous light source as a
painting too.

Plan what you want to achieve with light painting. The
lighting scheme should be hard to achieve conventionally.

NY Times Lens article about Harold Ross' work:

This is a link to Harold Ross' blog.  He talks about light painting and his techniques:

Much of this work is done with the light source pointed at the camera and recording the light source as it travels.  I want to concentrate on another aspect of light painting and that is lighting a subject with the use of a continuous light source such as a flashlight or even a cell phone.   Along with this idea of light painting is the idea of using multiple pops of a flash that is moved to different positions throughout the exposure.  Since digital photograph has made it easy to combine images with the use of layers, it is now practical to make a series of captures with the flash in different positions and combine them in layers.  The easiest way is to use the captures in Lightroom, selecting the images you want to use in Library Grid Mode, right click and choose Edit In…  Open as layers in Photoshop.  In Photoshop select all the layers and change the blending mode to Lighten.  Now all the light from all the layers will be revealed in the image.  Next you can turn each layer on and off using the eyeball indicator next to each layer.   You can control each of the layers  separately with the use of  masking and any of the adjustment tools.

To make an image using a continuous light you will need to keep the camera on a tripod and the shutter open.  This discussion is for the Canon 5DMIII.  Set the exposure for a length of time that will allow you to paint the light on the subject and the background (30 seconds is the maximum time allowable).  The room has to be dark enough that it doesn't pick up any stray light during the long exposure. The f stop and ISO are determined by trial and error. With practice a rhythm will develop and improve your painting skills.You can also use the Bulb setting but the shutter has to remain depressed during the entire exposure.  You can use the Canon Remote Switch RS-80N3 to release the shutter and keep it open by exposing the red dot on the release handle.  Slide the mechanism off of the red dot to close the shutter.

To make an image using a multiple flash image you are going to actually make multiple captures with each exposure having the flash in a new position.  With the camera on a tripod and the flash in one hand you setup the remote exposure as outlined below.  A special cable is needed which is outlined below. 

Remote Camera Setup

We learned how to remotely trigger the 5D MIII by using a special cable called the Canon N3 to mini phone by connecting the N3 side to the Canon's remote control terminal and the mini side to the Pocket Wizard II's camera port. By setting another Pocket Wizard Plus II to the same channel as the one attached to the camera, the camera shutter can be released by the remote Pocket Wizard Plus II when you press the test button remotely.   We need a third Pocket Wizard Plus II to be attached to a Canon 600EX-RT (this is the only Canon flash with a pc connection) using a pc to mini cable. The pc end is inserted into the flash's pc terminal and the mini end is plugged into the 3rd Pocket Wizard Plus III's flash terminal. The 3rd Wizard has to be set on a channel that is one number higher than the other two Wizards. The 600EX-RT is set on External Manual Metering by using the custom function 5 option 3 as described below.  Now we have the 600EX-RT and 3rd Pocket Wizard Plus II in one hand and the remote camera firing Pocket Wizard Plus III in the other. As we point the flash where we intend the light to land, we push the test button on the 1st Wizard and it trips the shutter and then automatically uses the pocket wizard mounded in the camera's hot shoe to sync with the flash and 3^rd PocketWizard that is set on the next higher numbered channel. The subject needs to remain perfectly still and then as many captures from as many positions can be captured.

To use the flash on Manual External Metering you will need to the page from the manual which is at the bottom of the page. There is a external reflected light sensor on the front of the 600EX-RT that will read the light where the flash is pointed.

Assignment 10 Canon Transmitter ST-E3=RT and 600EX-RT Flash

Work in Groups in the Studio for this Assignment.  Each member of the group should make a portrait using 3 Speedlites from different directions, controlled manually from the Transmitter attached to the camera which is also set on manual.  Each member of the group should make a unique lighting setup.  You can modify the light coming from the 600EX to a broad source of light by using diffusion, umbrella, soft box or bouncing off a wall or card. You can also use the light directly.

 Set the Master to GR and set A, B, C and D (Optional) to M.   The three slaves will set themselves to M after the test button on the transmitter is pressed.  Use the ST-E3-RT to adjust the setting manually.

Take a picture of the ambient light in the room at the fstop and shutter speed you will be using.  It should come out black. Post this picture with it's settings.

Post the the progression of images (ie one light, 2 lights, 3 lights etc) with final exposure for each shot (should all be the same)

I realize this is an ambitious assignment and that you might not have time for each member of the group to accomplish their own unique version.  Do the best you can and good luck.
