Simply having Fun

Apparently I broke the system when trying to convert 100 jpgs into one gif file. :D
So here is a simpler conversion, namely 3 jpgs into one gif, action slowed down 10x. :)

Bird landing on water dish, shot at 30 FPS.



Sony ILCE-1 + FE 400mm F2.8 GM OSS + 1.4X Teleconverter.

Cooper's Hawk lingering



Sony ILCE-1 + FE 400mm F2.8 GM OSS • f/2.8, 1/3,200 s, ISO 250.

Earlier this week, while helping a neighbor and friend with her A1 camera (exposure dial was sitting at an angle very loosely and seemed a bit damaged) the Cooper's Hawk was visiting again the water dish. It was lingering for at least an hour and a half at or in its "bath tub" or in the Juniper Tree/Bush next to it, preening its feathers. In these 90 minutes I had shot intermittently with my A1 about 6,000 frames and filled up both of my 160 GB - Sony CEA-G160T 160GB CFexpress Type A Memory Card (CEAG160T) - memory cards for a total of 320 GB.

On average each compressed raw file was about 55 MB in size.

So 55*6000/1000 = 330 GB,

in line with the total storage capacity of my 2 memory cards.
But how many of those 90 minutes could I actually document with images shot at 30 FPS.

So that's 6000/(30*60) = 3 minutes and 20 seconds coverage of the 90 minute elapse time.

In other words, for about 86 minutes and 40 seconds of those 90 minutes elapse time the A1 wasn't shooting images - provided my math is correct. Enough of this.


As one can see from the image above, the Hawk is standing on its right foot, its left foot tucked away in its feathers. This becomes a bit clearer from a short video animation I made from a few of m1 A1 images.

I wonder whether the Hawk has a problem with its left foot. Hmm.

After taking a bath the Hawk took off, shot a 30 FPS.
The gif animations below are shown at a frame rate of 30, 10, and 3 FPS.

30 FPS


10 FPS


3 FPS


More later. :D

Cooper's Hawk seems visiting its "Bath Tub" quite often. :D



The above endlessly repeating gif animation give the wrong impression.
The Hawk in actuality is resting, then shakes off water, then is resting agin.

I still feel there is something wrong with so many forest fires year after year. Nice work.

Thanks Lou, you mean forest fires?

We now have about 200,000 acres of a
fire break around town and have not had
a local forest fire in a decade or so.
But we get the smoke from fires out West.

The problem is too dense a tree population
because we as s society didn’t allow forest fires
to just burn and keep tree density down.

It seems the folks in charge are slowly catching on.

View from the Jemez Mountains:
Moon - distant Santa Fe - illuminated Rio Grande Canyon




Sony ILCE-1 + FE 50mm F1.2 GM (SEL50F12GM) @ f/11, 1/60 s, ISO 100.

Clicking and double clicking on the image results in full size view.
At bottom left one can even see the radio telescope that is part of the very long baseline interferometry project.
