At least three species of frogs in this recording. Which ones are they?

03/30/11 – Implosion welding power lugs

Arne — Wed, 30 Mar 2011 15:54:53 +0000

This is a technique Xcel Energy has not used (at least in our area). This Fox News link shows how it’s done.

And here’s the recording I made (about 2 miles away). Xcel Energy Implosion Swaging. The whole house shook!

03/01/11 – Moon and Venus

Arne — Wed, 02 Mar 2011 20:33:52 +0000

Still not close enough. I need to look ahead for these opportunities, I guess.

02/28/11 – More lunacy

Arne — Wed, 02 Mar 2011 20:22:06 +0000

Tried the “blue hour” again this morning, since Venus was evident near the moon. Need to catch it when they are closer, as this is not a very interesting photo.

Too much humidity in the air to get a good shot of the moon. This is about the best.

Finally, some sun!

02/19/11 – Shootin’ the moon

Arne — Fri, 25 Feb 2011 20:37:05 +0000

So how do you shoot the moon – assuming you want something other than the moon? If I set the camera up so I can see the branches of trees, I get something like this:

Olympus e620, 70-300 lens@70mm, ISO 100, f6.3, 30s

So, is this an underexposed shot of the sun or an overexposed shot of the moon? If I expose for the branches, I get this:

Olympus e620, 70-300 lens@70mm, ISO 100, f6.3, 2s

- and if I expose so I can see the detail in the moon, I get this:

Olympus e620, 70-300 lens@70mm, ISO 100, f6.3, 1/60s

Now I can’t see the branches. What I really want is the moon from the second shot and the branches from the first:

I used the freeware program Helicon Filter to accomplish this. Doesn’t really look natural, but it was kind of fun. What I really should have done is waited another 30 minutes for the “blue hour”, when the sky is lighter and this would look more natural. Unfortunately, started getting clouds before then. Here’s the last shot I could manage before the clouds took over:

See why it’s called the “blue hour”? You can just barely see the effects of the rising sun on the foreground. This also happens at sunset. Here’s one just a little too late, but you get the idea. 3 vertical photos stitched using Hugin.

02/18/11 – Full moon

Arne — Thu, 24 Feb 2011 19:03:01 +0000

Personally, I think a gibbous or crescent moon is more interesting, unless I can get some nice clouds or foreground. This one turned out pretty good, IMO. Tripod, 12s delay, manual after auto focus.

02/14/11 – Sunset

Arne — Wed, 23 Feb 2011 22:40:22 +0000

Kind of a muted, pleasantly layered sunset tonight. I tried a couple of different approaches; here’s one.

- and another, as a horizontal panoramic:

And finally, as a vertical panoramic (I’ve never tried this before):

I think I like the 1st one best.

02/13/11 – SUN!

Arne — Tue, 15 Feb 2011 00:48:34 +0000

Very nice, sunny day today. Spectacular clouds – missed some of the nicer ones .

Started out with a simple two shot (vertical) panoramic landscape.

Composition isn’t great, need something on the right. I added another frame.

Finally, added a fourth frame. The clouds cooperated to produce this layout (click for full panoramic). I think this is the best one.
