FYI, all beach areas in the major Hawaiian Islands are public (except for a few military areas), BUT you need a permit from the authorities to film/shoot commercially on them.

On article TwoEyes VR stereoscopic camera simulates human vision (52 comments in total)

Viewing the videos on the site reveals that there is imperfect sync between left and right captures. Note how the young dancer's fast moving arms are not synced.

This is THE most important parameter for any stereoscopic video! If they can't get that right...

ALL of these stereoscopic "solutions" require that you hold your gaze level (parallel with the recording interaxial axis). NONE of these will not provide true stereo if you hold your gaze at a significant angle (tilt your head to your shoulders) because that would require an almost infinite amount of data for true stereo VR imaging of a REAL scene at those (and all other) angles of gaze.

Cleaver and significantly impractical.

The wrench OD is too large to use in many applications (side clearance issues).

Impossible to apply the same torque vs a standard box wrench without risking mechanism damage (spreading/yielding).

I'll stay with Craftsman box and open end wrenches. ANY adjustable wrench is a mechanical compromise...

EthanP99: Heres how I would use it.

Imagine your home having its own battery that it slow charges and tops off while youre not at home. When you do come home, you can plug your car or any other device into that battery and get a very rapid charge without stressing the power grid.

Yes. THis is a realistic reply. The Electric Utility Industry would be HIGHLY interested in this type of evegy storage. Central, or even home based systems could be used to storage.

But...I would keep them far from the house...

lesnapanda: to charge a phone for full week in a couple seconds would require a charging current from a std 230V AC socket of around 185 amperes.

That 185 amps would easily exceed the main service breaker on most residences (although some have 200+ Amp service). What can you get from a standard US household 110 outlet before tripping breakers? 20 amps at most. So charging must take place in several minutes rather than seconds for the way the world is wired.

UNLESS you step down the charging voltage...then it might be possible...but it's still gonna take a huge conductor to handle the current. Think something like a set of good automotive battery jumper cables.

A great possibility.

First cam? Kodak Brownie 127. Moved up to a Practica (lousy, but it worked), then a Stereo Realist f2.8 for a long time...still have it. Rolled my own bulk fillm, did my own darkroom work, still have a pristine Kodak Precision Enlarger (which was a camera, too).

mpgxsvcd: Will there be an equivalent phone in the U.S.? I am really in a bind. I have a Samsung Note 7 that I really should return. However, none of the other phones seem like a great option to me.

I want Android with good battery life and at least 64 gigs of memory. Removable storage and removable battery would be great as well.

I really like the dual cameras in the iPhone but I just don't think I am ready to switch to IOS.

The V20 looks like a good phone on paper but there are way too many issues with it and the past LG phones.

The pixel looks good but it appears to only be available with 32 gigs of non-removable memory.

Any help is appreciated.

I suspect that almost ALL Chinese-built brands have maleware buried in the device firmware, phoning home now and then...

Actually Hydrogen is the lightest metal element. But it exists as a gas in most conditions.

The diffence between 13 Whrs and 11 Whrs is kinda academic...both can overheat, and release their stored energy to quickly too contain in the packaging,

A WHOLE lot more of Mortensen here:

You have to admit, once you see a sample of Mortensen's work, ya gotta look!

To qoute from a recent show of his work...

"Techniques he pioneered
for manipulating photographic images--a practice
for which he was once disparaged--now have digital
equivalents that are widely employed and accepted in
photography. A few decades of hindsight reveals him as
a visionary and a consummate artist ahead of his time.
In addition to his prescient technical innovations, his
photographs prefigured the imagery and visual mood that
have become the stock in trade for horror films, horror
comics, bondage porn, sorcery-themed fiction and all
things goth".

My comment was aimed at pointing out that to compare Ansel's darkroom work/manipulation to Photoshop and say he was "the modern day equivalent of a Photoshop Master when no one else was" is an error.

William Mortensen was as good at that craft as anyone at that time. Not to say his work is pleasing to most, but that he was Ansel's contemporary, who also practiced significant photo manipulation.

Don't ignore the comprehensive and spectacular work of William Mortensen (Ansel's alter ego of sorts) as another "darkroom master". Although not as well known, his imagery certainly has considerable visual impact.

Mortensen was just as big (if not the FIRST) photographic superstar.
