Schedule Changes

First change: This coming Wednesday 7/15 Class #10 We are going to feature the work of Martha Rial. Pulitzer Prize winner photojournalist she was a staffer at the Post Gazette and most recently at a daily paper in Florida. She just returned to Pittsburgh and will show us some of here Photo Projects. I have decided to also move the Business discussion to this class, so that all of you who expressed interest can hear that lecture.

This will mean a few good things for you all.

One The Environmental Portrait will be due on 7/22 (The week after next) We will also that day talk a little more about White backgrounds.

The White Background Portrait will be due on 7/29 ( I know that many of you will be on vacation) you can either bring it in early! or with permission drop it off with me. We will use the balance of this class to talk about Hot Shoe flashes.

The final project will be due on Aug 5.

A few of you have asked about Light meters and a RAW discussion I could make time but only before class this coming Wednesday, which I know does not work for many of you that work till 5pm. It is a really tight summer time wise.

I hope you have a great weekend.

Inverse Square Law & Guide Numbers

In physics, an inverse-square law is any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity. <wikipedia>

Lightsource Intensity =1 / Distance squared

The Inverse Square Law defines the level of light from a fixed light source relative to the distance from the light source.

If the Light Source produces an output of light equal to X at a distance from light source to subject Y, at a lightsource to subject distance two times (twice) Y, the Light Source output will be equal to 1/4 of X.

Calculating Range of Guide Numbers article

Giude Numbers = Flash-to-subject distance * f/stop
At 10 feet:
f * 10 = GN
f/8 * 10 = 80

Class Notes #1 Summer : Light

Great class last night. Wanted to leave you with this reminder.

For next week, 2 examples of Light. books, movies, magazines, life.

Book Recommendation: MAKING MOVIES by Sidney Lumet published by Vintage

quote from page 26: "It is in the preparation. Do mountains of preparation kill spontaneity? Absolutely not. I've found that it's just the opposite. When you know what you're doing, you feel much freer to improvise."

Emerging Photographer Ross Mantle

Last evening we talked about the Final Project for the studio lighting class.

I asked emerging photographer, Ross Mantle, a recent graduate of Ohio University and their Photo Journalism program. Ross spoke about his most recent photo projects and his experience working as an intern in a variety of newspapers around the country.

Ross, touched on a few very important messages for my students.

- Editing your projects, go back and visit project archives over and over again, because the project or your vision may change over time and you will see things in your edit that you didn't see before.

-Learn from your failures. Mistakes can lead to new ideas and approaches.

-Start projects, by just starting them. Do something, the rest will come.

I think this is good advice for all photographers.

#4 Class Notes Using Calumet Strobe & Soft Box

We went through the Calumet Studio Flash system (#2) with a Chimera softbox.

The demo illustrated proper incident meter technique.

We began the semester long discussion of Lighting Ratios. (pg 62-63 in the Photographic Lighting textbook 4th Edition.)

Here is an article that helps explain it.

Here is a useful chart to print out.

Here is a link to another Flash meter Calibration technique.

I want to continue our discussions of Light. Understanding the nature of light. (pg 11 in the Photographic Lighting textbook 4th Edition.)
Here are some of the Light Characteristics.

-Source
-Intensity
-Quality
-Direction
-Contrast
-Color
