Not Much to Say

Well, it's been a long time ...

For those readers who might have assumed that I've finally gotten my hypergraphia under control, I've actually been working on a variety of other writing projects, instructing, and flying a fair amount. I think it was W. Somerset Maugham who said "Having nothing to say, I said nothing." In that vein, here are some photos of a recent flight that highlight the recent snowfall in the Bay Area mountains and the weird behavior of the iPhone camera's shutter with regard to spinning propellers.

I'm sure I'll have something substantive to say soon, but until then ...

My cell camera does that too.

I agree, don't write "just because." But it's still good to hear from you.

I had heard vague, hand-wavy explanations of the phenomenon before, but the explanation and video on this page is crystal clear:

Wayne,

Thanks for that link! I agree that it is a very clear explanation of the iPhone propeller effect.

My old digital camera does the exact same thing to props, unless they are at idle, then they just look "bent" like they are made of rubber.

Cam is an old Vivitar, so old the biggest SD card it can take is 128Mb (yes MEGAbytes)
