Gosh, this would be perfect. I could not only store all of my images and media in one place, but it would have enough for both live backup AND be able to take the place of my two offsite backups all in one place!!

(I'm kidding)

On article Epson's 4K home projectors to go on sale next month (59 comments in total)
In reply to:

halc: 2300-2500 lumen (c. 2000 calibrated) is nowhere enough for proper HDR peak brightness. Yes, better than 1300 lumen, but nowhere near what it should be.

HDR is really the game that breaks home cinema projectors. Next year will start getting >1000 nits local peak brightness (with near 0 nits black level) 4K UHD HDR TVs with FALD control at screen sizes over 60" and prices below $2000USD.

No home cinema projector can match this. Not even the Sonys. You need insane lasers (probably with water cooling), prof high gain screen and a sound box to isolate the insane fan noise of cooling.

And no, the Epsons in question are not a real 4K UHD resolution projectors.

Under what conditions do you want a projector with 300+ ft-lamberts? And if you decide you are going to do a backyard movie in the afternoon, you're probably not going to be worried about getting a zero black level.

Turbguy1: Neat! What's the frame rate? Based on the exhaust plume internal details and ground dust movement, it's really fast.

And I always question: "Why test horizontally when a rocket is used vertically (most of the time)?

It's easier to strap a rocket down horizontally instead of vertically - less superstructure to deal with. Many test fires on smaller rockets are done vertically with the engine pointed upwards so that it just pushes into the ground. Amateurs occasionally just dig a hole if they want to see burn characteristics and overall rate and aren't taking data.

Alexramos: I don't understand the whole think with extra batteries.
I use to travel a lot and I stopped using my DSLRs and now my Note (4 and 5) has been my only tool. Even having removable battery in the Note 4, I always think this is the most unpractical way for extra juice.
When going on a trip, a 4000 mAh battery cover is attached to my phone, plus a external fast charging battery if needed. From the Note 4 to the current 5, this has been the most practical, simple and faster way to keep my phone going on.
I still don't see how an extra battery is the "best solution" for power limitation on smartphones especially for people that state they are going to remote areas.
Extra batteries for the note 4 require to switch batteries if both wanted to be recovered after a full day usage, but a battery cover just needs to be plugin for charging the whole system.

Zerolemon batteries are usually external, with an expanded back. By the time you add on the back, you may as well put on a case (imho, of course). My last two phones were the G3 and G4, and the spare battery option has saved my bacon a couple of times. I'm getting a Note 7, as I recently found (while playing Pokemon, of all things) that carrying an external 37mWh battery is not much more cumbersome than two extra 12mWh spares, the external can stay in my pocket and be connected to a 1m wire and still be usable as a phone, and I don't have to manually power down my phone and wait for it to cold reboot. That reboot seems trivial in a vacuum, but it's forever if you're in a hurry - like trying to find your gate if you're connecting flight is super tight, or you need to pull up a mobile ticket or payment, or your battery dies in the middle of a conversation and the other person is trying to call you back.

In reply to:

BigBen08: Seems odd they use the name Note. Samsung has a line of Note phones.

Yeah, but this is the Note 8, so it's a whole generation better than Samsung's Note 7. You can even get the Huawai with more gee bees.

In reply to:

noflashplease: Considering that SSDs have a limited number of write cycles, the Microsoft Pix app could really trash the solid state memory in a lot iPhones by constantly writing and deleting photos. It's should be very obvious that this app is constantly taking photos when it is open, in anticipation of the user hitting the shutter button, with each photo overwriting memory and burning through a write cycle. How exactly is that a good idea for SSD longevity in any device?

Most SSDs used in devices these days have a write endurance on the order of 6-10 years when writing at their rated speed for 8+ hours every single day. Unless you have a base model where most of the OS data is static and it severely limits your active write area, the phone battery will be dead far sooner than you can ever hope to out-write even TLC cells. Unless your retention of devices is long enough that you are still using an original iPhone today, you probably will never have to worry about it.

Cameracist: What about your own Windows Mobile 10, Microsoft?

This is perhaps the most frustrating thing about MS - instead of leveraging their software to promote and maximize the utility of their hardware, they routinely ignore their own devices, and then wonder why nobody buys them.

I don't think they have many. The real question is: where are the lawyers. I know they have an entire army of them.

On article Real world test: The Panono is a 108MP spherical camera (146 comments in total)

Until it produces a view which is rectilinear and nearly free of wide angle distortion, it will remain a gimmick. To be immersive the viewing experience needs to be like turning your head. It's like 3D content - so much of it is exaggerated to make you say "woah, look at that 3D effect" instead of "wow, that looks like real life".

In reply to:

TonyPM: Why make a new format when you can make the existing format better?

What will happen If micro SD manufacturers make those as fast as samsungs new format but cheaper?

The UHS-II standard tops out at 312.5 MB/s transfer speed. That makes it only about 2/3 the max read speed, but is still faster than anything can write - and write speed is what really matters for most applications. And UHS-II is backwards compatible with uSD. The write bottleneck is on the silicon, not on the interface. That may change in the future, but I would hope that whatever is "next" is an order of magnitude faster than what is on the market, not a paltry 60%.

In reply to:

Roland Karlsson: One question - what is that green "laser" ray in the COSRAY image?

It's probably a laser satellite ranging rig. http://goo.gl/9l86Gi

I don't know if it's one of the ones from the Goddard group, but it's almost certainly what it is. I worked in that group when I was an aerospace engineering student back in the late 80s. There are satellites which have corner cubes (LAGEOS - http://goo.gl/PKV03R ) on them, as well as CC set on the moon during Apollo, which are used for ranging. Back then, the laser is was an Nd:YAG pumped laser at 532nm with a 4" diameter. The time of flight is recorded (pulses @ 5 Hz) over the visible orbit and the exact location on earth is known very precisely and is used to track global tectonic plate movement.

The old units (back then) were mounted in semi-trailers, and the newer (TLRS) units were mounted in large box truck-sized trailers. The TLRS units used these new fangled things called CCDs to collect - the old ones used Photomultiplier Tubes. We could detect 3-5 photon returns from the moon. (Take *that* Nikon!)

In reply to:

fuxicek: There should be easy way around this patent, just activate "airplane mode". Unless they come with a new patent, that allows you to turn on the "airplane mode" only on airplanes and nowhere else....

And, properly implemented, the sensor would need to receive a certain minimum level of IR based on the scene to prevent you from putting an IR notch filter over the lens.

In reply to:

sh10453: A "microSD", at such speeds, especially write speeds, and 4K video, seems to be a recipe for disaster, no matter what SanDisk claims about withstanding extreme temperature.
High temperature is electronics worst enemy.

Time will tell, but I would hate to see the videographer's tears half-way in a critical 4K commercial shoot, a wedding, or other scenes that cannot be repeated, due to card failure caused by extreme temperature.

I avoid microSD's, and devices that can only use microSD's as much as I can.
Unfortunately, that cannot be avoided with phones, or at least most phones.

Have you taken apart an SD card lately? They're almost entirely air. The contacts at the front are connected to a (surprise!) microSD sized package at the front of the card and the back half is just empty space. I've not dissected a 256 or 512GB card, and I suspect they are more fully populated, but the <16GB cards I've popped open are all essentially microSD size silicon inside.

In reply to:

JordanAT: I'm curious why the lens is so (physically) large. It looks like it could have been easily placed in a housing with a 42mm filter ring and made 20-30mm shorter. Is there thermal management going on in the barrel? Massive gearing? It's like someone from marketing looked at it and said, "you know, for four grand it should look bigger." Maybe just 67mm is the standard filter size for most Hassy lenses (seriously - I've held one twice in my life, the last time was 20+ years ago...I really don't know if there is a standard they were matching).

Otherwise, it looks like a well=thought out camera. It's certainly too early to say, but it *feels* like someone fired all the MBAs, pulled together some real photographers and engineers and decided to build a high end still camera that mattered.

@Greynerd - I'm completely fine with using better optics over software correction, but I'm unaware of any lens which has internal optics which are appreciably larger than the front or rear elements. Physics for convex lenses generally dictates the opposite - that internal elements are smaller because the light rays are converging towards the interior of the group and then diverging until the rear element where they emerge. The front element of this lens couldn't be more than 30mm (photo 1), and the rear element not more than 20mm (Photo 13).

The leaf shutter certainly defines the maximum barrel dimension, and I presume that it was just easier (or sexier) to make the whole barrel that diameter, despite the weight penalty.

I can buy the leaf-shutter argument, but all you need to do is look at the front and rear optics of the lens in the photos to see that you don't really need much glass to make an F3.5 lens with a 45mm FL.

JordanAT: I had a chance to hold one of these over the weekend, and I was surprised how deep (front to back) the body is. I don't have small hands, but it actually felt a bit large/awkward (and I used to shoot Nikon F & D series). Beautiful images, though. If I ever go back to a non-pocketable fixed lens camera, this would be at the top of my list.

Now I feel special. ;-) It's like reddit gold, but flashier (and without benefits). :-D BTW - I messed with one at the B+H Store in NYC while on vacation, along with several others I'm considering. Living in a small town, I've practically forgotten what it's like to actually have a store that stocks anything anymore.
