My Front Yardby AnnComment: Originally posted by MelonMusketeer: That's well done. I wonder what the f# is for the pinhole projection on the wall? I guess it could calculated from your camera settings by using the "f16, sunny day, iso" rule.
In any case, the clarity and sharpness of the projected image speaks well for large format imaging. |
I used the usual calculations for determining the pinhole size, assuming a 10 foot focal length, and it came to 3mm. My rough calculation based on camera settings, exposure, and the settings of the camera turned around and pointed directly at the yard is that this is f/2000ish. When I was shooting, once my eyes adjusted I could clearly see the leaves on the bed, but the blue car was just a dim blue blur, and I couldn't see the hedge across the street at all. |

Hooded orioleby MelethiaComment: Wow! Orioles are incredibly shy, and don't stick around long enough to have their picture taken very often. |

HB 33by MelethiaComment: Female Anna's. Sweet little thing, isn't she. The males will have the iridescent pink hoods, and the females will be all green. |

Rodney PAW week1by HornOUBetComment: Rodney looks very sweet. And sleepy.
I got a N1 V3 a couple of months ago, with a CX 70-300. We'll see if I end up using it or dumping it. The jury is still out. |
