big sur


Morey and i spent several days in big sur a few weeks ago. we stayed in some cabins that had little kitchen and sat right on the river. we had a tiny deck off the kitchen and a skylight in the shower.
i brought my new toys with me and spent some time getting to know how the new anti lenses work. i had a zone plate and a keyhole optic for the lensbaby. these drop into the composer i've mentioned earlier. they are 50 mm focal length; Pinhole: f/177; Zone Plate f/19. these are TINY apertures. you can't see a thing in normal light when you look thru the lens! you must take long exposures. so i used the preview more than usual and took a million shots til i got an idea of what is going on. there is also a color shift because bright colors have higher (faster??) light waves so the light colors hit the capture sensor many more times than the darker colors. for example, it you were shooting a black and white subject the white would hit the sensor so many more times than the black that the white image spills over to the black and it looks ghost like. the color shit comes about when you have colors that tend to occur and certain frequencies, like yell0w tends to be fast and dark blue is very slow. but these colors make up most of the oranges and pinks and have an impact on green and magenta. skeptical? try it in photo shop. just try turning on and off the channels in a color image and see how surprised you are!
actually, i just messed with the channel mixer for several of these and while i'm right there's a color shift i may not be at all right about which way it's shifting!
so i'm still trying to decide if i like the images i captured!
