ASSIGNMENT for this coming month - Portals
We were going through some options for the September assignment and got to suggestions like "doors" and "windows." It may have been George Kerr who popped out with "Portals," or any opening or passage between... Be as literal or metaphorical as you care to be.
What would be separate?
Rooms? Property? People?
What would be the opening? Door? Window? Conversation?
Please eMail your photos by noon, the day prior to each meeting, so I can get them all online for your viewing that evening.
PROGRAM for upcoming meeting
During our August meeting we looked at some photos in Picasa and noted that, if you were using Picasa anyhow, why not upload them to the Picasa Web Albums site? We looked at how.
The September program won't be based on the upcoming assignment because there won't be one for October. Our special guest for the October meeting, photographer and Soul Collage practitioner and teacher, Catherine Anderson, will be with us and we'll devote the entire session to her visit. I've met with Catherine twice and promise you a deeply involving visit with one of the most creative persons I've personally met. Do look at her web site, www.catherineandersonstudio.com

ANNOUNCEMENTS
A new and ongoing assignment... for ALL MONTHS
Each month we have a different assignment which, in most months, we evaluate and discuss. This theme is different. Along with the theme for any given month we're adding this as a theme for all months. Submit one or two, for sharing only, and we'll show them monthly and compile them for later. At some point this will become its own exhibit. It's a long-term idea for anyone's contribution.
"PHOTOGRAPH the change you want to see in the world."
Gandhi's comment, "Be the change you want to see in the world" was the genesis of this thought. So, what gave birth to the thought?
It was Margaret Bourke White who took most of the photo's we think of when we think of the Mahatma, particularly the one of him and his spinning wheel. Read that story HERE.
Somewhere I'd heard of an interchange between Gandhi and Bourke-White in which he commented on photography as a very worthy endeavor -- that spinning was better but photography was worthwhile. I tried to locate the exact quote, to no avail. I was left with this morphed thought that I'm suggesting as an ongoing theme for our photo community -- something we'll "shoot for" each month.
Here are some starter ideas...
 
 
Annual Photo Exhibit - striking the show.
Our work has graced the walls of the newly established Cornwell Gallery for a few months beyond our original plan. Heck, are we supposed to tell interested viewers that they've had enough? I think not!
At the same time several of us are looking forward to seeing our work back in place at home and it's probably time to offer some new work, possibly in another visual medium, in this nicely-redefined space. OK, then, here's a decision:
As soon as possible after the May meeting we'll clear the hall of our work and re-install some of the earlier photos (and some additions) as a placeholder until the next visual event in the Gallery. When you join us next Wednesday (you will be joining us, no?) plan to collect your photo(s) to return to their rightful place in your home. We'll take a few moments to do this. I'll enlist Nancy, Tod, and Morgan Spier in taking the rest down and storing them for later collection. How's that?

NOTES on Color Theory from our July 2011 program
Last month's program looked at color, with an introduction to different models or ways of looking at how colors mix. That is the basis for this month's assignment.
So, what is this assignment about? Send us some nice photos of something that is mostly made up of complementary colors.
Complementary colors for light would be:
RED with CYAN
BLUE with YELLOW
GREEN with MAGENTA
Complementary colors for paint would be:
RED with GREEN
BLUE with ORANGE
YELLOW with PURPLE
WARNING...
WARNING...
WARNING... here comes the explanation (aka, theory).
Most of us were introduced to a color wheel in school which consisted of primary colors (RED, BLUE, YELLOW) which were used to create all other colors. If you mixed RED and BLUE you got PURPLE, but there was nothing you could combine to make either RED or BLUE, hence, they were primary colors by definition.
Colors across each other are complementary. They tend to work well together. Think RED and GREEN and you think of Christmas. PURPLE and YELLOW are wonderful floral colors together. So it goes.
What was new to many of us was the idea that there are other primary colors when you're talking about light (which photographers usually are).
SUBTRACTIVE COLOR (CMY)
If you start with a white sheet of paper the PRIMARY COLORS for your printer are CYAN (light blue-green), MAGENTA (pinkish purple), and YELLOW. You print all other colors by mixing these, and BLACK, as needed.
It costs about sixty dollars when you run out.
It's called the SUBTRACTIVE model since you filter, or "subtract" from white to get the color you need. Where two primaries overlap you get secondary colors. If you overlap all three, full strength, you get BLACK (or nearly so, which is why printers also use black ink).
This model is referred to as CMY, initials for the primary colors. If you add black, it's CMYK.
In the SUBTRACTIVE model, complementary colors (directly across from each other) are:
CYAN with RED
MAGENTA with GREEN
YELLOW with BLUE
ADDITIVE COLOR (RGB)
On the other hand, if you start with a black screen, as with a computer monitor, a TV, or a screen in a darkened room, there is no color... until you add it... with light.
Here, your PRIMARY COLORS are RED, GREEN and BLUE. On a TV or a computer monitor there are only these three colors - nothing else. Nothing. Every other color you see is a combination of RED, GREEN and/or BLUE pixels lighting up in whatever proportion is needed to mix the desired color. Your computer does this for you; when you look at a blue sky in your photos the computer turns on mostly BLUE and GREEN and may add a bit of RED. If your photo includes YELLOW the computer tells your monitor to mix GREEN and RED. Yup. GREEN and RED makes YELLOW on a monitor. All three colors, full strength, produce... uh... WHITE.
This model is referred to as RGB, for the primary colors.
With the ADDITIVE model, complementary colors are the same as, but the inverse of, those in the SUBTRACTIVE model:
RED and CYAN (primary and secondary reversed from SUBTRACTIVE color)
GREEN and MAGENTA (ditto)
BLUE and YELLOW (ditto)
In other words, the PRIMARIES in the SUBTRACTIVE model are the SECONDARIES in the
ADDITIVE model, and vice-versa. As a result, when we're dealing with light, complementary colors are the same no matter the model.
HERE is a link with an alternate description. It's fun to Google stuff like this, too.
So... choose any color model you want (color wheel, subtractive, additive) and show us a photo of something that is mostly made up of complementary colors.
With light, that would be:
RED and CYAN
BLUE and YELLOW
GREEN and MAGENTA
With paint, that would be:
RED and GREEN
BLUE and ORANGE
YELLOW and PURPLE

NOTES on Black and White from our March 2011 program
My usual suggestion on this is to shoot EVERYTHING in color, and then reduce that to monochrome if you like. For users of the free photo editor from Google, Picasa, it's a simple matter once you chosen your photo:
Go to EFFECTS
Apply one or more of the following effects:
B&W, or
SEPIA, or
B&W, then WARMIFY, then SATURATION
That last option lets you first convert your image to monochrome. Then using the WARMIFY effect lets you add a sepia-like color to it, but with a different look than just choosing SEPIA (compare for yourself). Then, adjusting SATURATION let's you choose how strong or subtle your warm "toning" will be. For example...
Original |
B&W |
Sepia |
B&W + Warm |
B&W + Warm
+Desaturate |
You can see all these examples, larger, by clicking HERE.
Original |
Here are those same effects using a mountain scenic: |
B&W
|
Sepia |
B&W + Warm |
 B&W + Warm
+Desaturate |
If you're a user of Photoshop, or similar image editor, your options are even more varied. In addition to "toning" like that described above, you can also add effects similar to putting colored filters over your lens while shooting black and white film.
Choose your photo and choose Image > Adjustments > Black & White
Then play with the color sliders to see the effect of different "color filters" on your black & white "film." For example, a "red filter" will make red things lighter and complementary colors darker. That's why a red filter, on black and white film, makes clouds stand out -- it doesn't do a thing to the white clouds but it makes the blue sky darker, so the clouds stand out against the darker sky tones. Ask Ansel.
You'd do well to check the notes on Monitor Calibration, below, and adjust yours before all this so that what you see on your screen is a good indication of what others will see, also.

NOTES on Montor Calibration from our October 2009 program
It's something that nags at all of us, where we see one thing on the monitor and another on paper, or different results on different monitors. Which is right?
While there are complex standards for these things, basic adjustments that will get you well into the ballpark aren't too difficult.
Click HERE to go to a site you can use to get your monitor calibrated for a full range of grey tones. This is especially important when we're working in black and white, and is a prerequisite to good color on your screen. It's a single chart you can use for reference. Read it carefully and follow instructions.
Click HERE for a site that will appeal to engineers, explaining the parts that most the rest of us don't even want to know but that engineers will find essential. You know who you are.
If you liked that last one, you'll really want to click HERE for a step-by-step on everything from gamma to white-point. Egad. (BTW, this page is offered by Adorama, who sells stuff, including monitor calibration systems.)

Monthly Photo Submissions
We encourage up to two entries from each photographer each month, asking that you indicate a first and second choice in case we have more entries than we can manage as a group (we need to limit total entries to 25 on a given month). If you'd like to send one or two additional photos for viewing and posting online, but not judging, we're glad to include them.
Send your photos to jbambach@mpbconline.org by noon the day before the meeting (please?). If you don't get an eMail confirmation that we've received your submission, within 24 hours, please call John Bambach (704-927-0774 x602).
See our galleries from previous months (in the left column) for an idea of what we do. For more on the group, what we do and what we're about, download the following documents. Then come join us!
