Photograph #61 There is Something About the Moon
Friday, July 30th, 2010Photograph #60 Not Becoming Grapes
Thursday, July 29th, 2010This vine is nearly 50 years old
And we’ve cared for it for half of that time, but we have never gotten a good crop of grapes from it. The reason, as Beth gently tells me, below, is that it is a Virgina Creeper and not a grapevine, at all. Wyoming is just too dry in the late summer, even when we water. The birds, however, think it is just keen. 50mm f4 1/125s
Photograph #59 The Earth Is Strong

Tuesday, July 27th, 2010Photograph #57 Touched By the Sun
Monday, July 26th, 2010Some people won’t believe the color here
And I wouldn’t either, if I hadn’t been there, myself. This lasted long enough for me to see, swivel the camera, set the exposure and make one click. Maybe 15 seconds in all. The sky above the clouds was dusk gray, very little blue, and I am thankful I did not over-expose it too much.
Photograph #56 Almost Full
Sunday, July 25th, 2010Photograph #55 The Sky’s the Thing
Saturday, July 24th, 2010Partial color images are not usually my thing
I think they are too often gimmicky, but. Here, I wanted to diminish the foreground, which was full of deep greens and golds, and yet keep the framing. I desaturated, never finding the sweet spot until the foreground was all the way to black & white.
This is one of those effects that can be done with film but seldom is because it’s not easy. Digital development makes it almost too simple.
Photograph #54 East End of Casper Mountain
Friday, July 23rd, 2010It’s unusual to talk about the ‘end’ of a mountain
But Casper Mountain is something like ten miles long, from East to West, and rises abruptly almost 3000 feet from the flatlands at it’s foot. Wikipedia says it’s so long and wide that it is visible from space, at the height the Shuttle and International Space Station fly. I’d like to test that personally, someday.
Photograph #53 Pure Prairie Sky
Thursday, July 22nd, 2010Here’s why the exposure details are worthless
To any other photographer but the one making the exposure. The ‘exposure value’ of the clouds here is ’16′. I’m shooting an nominal ISO of 100, focused at infinity. I could be shooting at f11, f16, or f22 with my 50mm lens, depending on the shutter speed.
Which was it? Can you tell?
The most important thing a photographer can learn is the proper level of exposure. This is given by the ‘exposure value’ or absolute level of light reflected from the brightest object in the frame, exclusive of specular highlights, as from waves or chrome. This value, in conjunction with the ISO of the medium, then determines the range of shutter speed/aperture settings that will expose the medium properly.
A light meter, whether internal to the camera or hand-held, reads the EV and does the math for you. The photographer then makes subjective judgments about depth of field or the degree of motion smear, or the higher or lower tonal values desired.
The actual lens/shutter settings will therefore vary from one person to another, from one situation to another, and will be specific to the moment and situation. There are times the photographer ignores the ‘right’ EV and exposes higher or lower in order to make a good photograph. In this particular case, I followed my light meter.
