Cat eyes - close-ups
I tried photographing the eyes of my cat today and got the best result so far, I think...
Here's the resting test subject, unaware of my coming intrusion:
...but her eyes are not open... she is very sleepy here...
...so I had to alert her by making some meowing sounds myself... please, open your eyes...
The right eye - probably my most successful eye shot so far...
...a lot of details can be seen in the iris, which almost looks like it has shades of gold color...
...and here's the left eye, also with nice details I think...
And here's the gear I used, Sony A7R + 2x teleconverter + Canon nFD 100mm Macro...
...it may look a bit cumbersome, but it's pretty ok to shoot handheld actually...

Haha, it was April Fools' Day yesterday and I happened to read a fun review from the serious photography site DPReview... they reviewed a toy camera like it was a serious camera, pretty fun...
Note that the camera seems to be real; it is a really tiny plastic 1.3MP camera (link: Sanrio character toy Cameras DSC-PIENI Hello Kitty).
Image: behold the mighty Hello Kitty camera. Quote: "Taking photos is best accomplished with a 'spray and pray' approach. You point, shoot and hope. I say 'hope' because the camera doesn't actually take a photo of what's in front of you but something off to one side. It's like having an integrated AI that guesses what you're trying to photograph, then fails spectacularly every time."

They did a short video review too:

My grandson, the Brainiac. I think it's just the angle of the camera, but he looks like a comic book villain.

Experimental time again...
...some shots taken today with Helios 44 with a reversed front element...
...which means there will be no "normal" photos...
First three shots of my cat...
Dream cat #1 (this photo looks quite "normal" though, yet very soft)
Dream cat #2 (enjoying the sunlight)
Dream cat #3 (upright)
Afterwards I went for a short walk, though it was very cold outside...
A magic ivy against a brick wall
Dreamy pink flowers on tree (the bokeh is crazy in this one)
Glowing springtime
(crazy bokeh here too; note: I've enhanced the colors in this one since I felt like it)
(Lens used: Helios 44M7 58mm f/2 with reversed front element + CPL filter)

Smoked my main DC solar panel disconnect in my remote power shed testing some equipment I'm designing. Looks like it just had a bad pole (twisted or bent) as the rest had the same current but look fine.
This is why you don't go cheap with safety equipment, it was all contained but the smoke.
Proper DC and UL rated for the job.

In Spindale, North Carolina yesterday:
I wonder if they offer degrees in HVAC technology... apparently not, but they do offer a Basic HVAC Certificate.
[added] Now I see I've mentioned this place before, and @berkeman noted the origin of the name. I had only seen signs pointing towards it from highway US-221 which bypasses Spindale, but yesterday I actually drove around the campus, and through Spindale. Typical mid 1960s academic architecture.

Mr. Mittens (my neighbor's cat) popped over a couple days ago for a late morning/early afternoon nap. I took a couple of test shots with Mittens since I wanted to ensure my rangefinder camera was all set and ready anyway.
Figure 1. Mittens relaxing in a late morning sunbeam.
'Missed critical focus on that one by a bit (see Fig. 1). That's on me. But Mr. Mittens posed so well I had to post it. (In my defense, it's difficult to manually focus when crouched near to the ground. And the lighting was difficult. But I aught to have done better. I'll keep practicing.)
Figure 2. Mr. Mittens being slightly curious as to why I was prone on my belly pointing a rangefinder camera at him from underneath a guitar stand.
While somewhat curious, he was more sleepy than curious (see Fig. 2).

Stockport North West England shares a boarder with Manchester. Buddy Rich used to play there regularly, the Davenport Theatre. This building, the Plaza, went up in 1932.

No idea about this one. 1885, it is most likely listed but that does not mean it gets used or looked after.

Forgot the arc shield pictures.
Passed the heat test, highly recommended for field duty.
Anyone know what type of plastic they use? I'd like to get some (clear if possible) for some DIY spark shields over interconnect rails.
I found this but it's only in black.

Natural would be better as I would like to see status LEDS behind the shield.

Thanks. Google shopping just gets me a blank screen. I must have all of their tracking crap blocked.BillTre said:

Im pretty sure the enamel used in electric motor winding is a polyamide. I would think you would be on the right track choosing that material.

That one, Kapton, is close to magic; I've used it in the distant past because it is resistant to corona discharge. It also has a wide temperature tolerance of -450F to +750F and reportedly available in Clear or translucent Tan, with Tan being more common.nsaspook said:
