aramgrg: Lytro's Revolutionary needs to be taken with grain of salt. We saw it's "revolutionary" field cameras are useless in real life.

Adding to Lars V's comment, the big difference I see between the professional cinematography and consumer photography markets is what proportion of the cost the equipment represents.

Their previous still cameras were quite expensive given the ultimate quality of the still photo they could produce. The audience that might have been okay with the quality wasn't interested in the price, and the camera just didn't offer enough for the audience that might have been willing to pay.

Cinematography is a bit different. This camera and the equipment and software needed to use it sound massively expensive, but so is everything else about the kind of high-budget production they seem to be targeting. If Lytro can deliver the quality, I expect they'll find their market.

Is there some reason I can't full-screen the embedded video? (I assume this is an option that was set intentionally on the player.)

Apparently they sent out the press release before actually starting their Kickstarter campaign. Admittedly I'd really have to see some reviews before putting any money into something like this, but it still seems like a pretty significant missed opportunity to almost have the filter for sale (the Kickstarter is supposed to launch in February), but not quite when the news goes out.

On article In Fine Detail: Canon EOS 5DS / 5DS R In-Depth Review (728 comments in total)

Why have you labeled "Self-cancelling" under "Optical low-pass" in green, implying it's the better spec? Including a low pass filter is not better or worse, and simply a function of the camera's intended use. In fact, having the low pass filter is arguably better all other things being equal and with a perfectly sharp lens, as otherwise you can end up with artifacts that are impossible to remove. (Moire can certainly be masked with the right filter, but it's mathematically impossible to recover the lost data. Post-processing filters can only make a guess at what's aliasing and what isn't.)

I'm happy to see Canon has left this choice up to the photographer, as opposed to Sony or Nikon, which seem to have decided the low pass filter is no longer necessary. I'd hate to see this spec chart drive someone to buy the R version simply because they believe it's "better".

yodog: I would gladly pay $10,000 for a 600mm telephoto and shoot it from below or maybe rent a helicopter...but then I would have to charge them $11,000 for the shoot. I'm so acrophobic that I am afraid of the word "heights". The photographer didn't say much about the descent down the cables, but I think that would be worse.

That, and I'm not sure what the park service would think of a helicopter hovering around Half Dome.

Gesture: Don't care if I get panned. USPS is superb. The speed packages go cross-country and the local delivery person knows you and watches for your items. The "deficits" are because of the way USPS must fund pension and health care obligations vis a vis other nonprofit organizations, as I understand it.

I find less "crush" issues when USPS and FedEx deliver a package. A great postal system is an important part of a democracy.

USPS is great in terms of getting a package from one post office to another, but the experience from there depends a lot on the local delivery person. Where I am, UPS and Fedex always deliver to the door. USPS might leave a notice in the mail box if you're lucky, and good luck getting them to actually pickup the notice if you want to request redelivery. Basically, you need to just track the package and deal directly with the post office when it arrives.

What I find USPS is really good for is international orders. UPS and Fedex frequently make a big deal about customs and fees. I've never had a problem with the handoff between USPS and the local postal service in the origin / destination country. Of course there are some countries where the local postal service itself can be problematic.

On article Nikon D810: What You Need to Know (142 comments in total)
In reply to:

jnxr: Nikon need 2 tries to get it right for every FF model:
D4 ---> D4s
D600 ---> D610
D800 ---> D810
Moral of the story, don't buy their first model, wait for the fixed version.

I've been pretty happy with my D800 for the past 2 years. The only thing I really wish they'd add is 2 and 3 stop bracketing (which the D600 has, amusingly), but I'm not sure even the D810 addresses that.

I did always think it was kind of silly that phones released around the same time as the D800 could do 1080p60, but it couldn't, though.

"Naturally though [the slight blurring due to the OLPF] also means that in terms of raw resolution, you're never quite seeing the potential of your camera's pixel count"

That isn't entirely accurate. The true resolution of a 36 MP Bayer sensor is 18 MP in green and 9 MP in red and blue. You could store the result in a standard 18 MP file without losing anything and still have 50% more pixel data than you need. A 36 MP sensor does not have the potential to produce an accurate, sharp 36 MP color image.

The point of the OLPF is to distribute each color of light over the corresponding pixels so there are no holes. That means you won't get super sharp, aliased lines, but you also won't end up with artifacts (moire) by trying to imagine details that the sensor can't actually resolve. Without the OLPF, you're just taking the 36 MP grayscale image, throwing away some colors at each pixel, and hoping you don't lose anything important.

No, this is a very different camera from the D4/D4s.

In reply to:

MarshallG: Anybody else a little leery about this trend of removing the low pass and anti-aliasing filters? Surely there were good reasons to use them in the first place.

And when you're trying to shoot a scene that does generate moire at 36 MP, using a lens that can resolve the detail?

The reasons for adding an AA filter at 4 MP are just as valid at 36 MP. If your scene doesn't have the detail, it will make little difference unless you like to view images straight out of the camera at 100% and marvel at how sharp aliased lines can be. If it does, an AA filter avoids nasty sampling artifacts (moire) that software can really only guess at how to resolve. Once you capture the image without an AA filter, the information needed to correctly disambiguate true low frequency detail from false detail created by high frequencies the camera isn't equipped to capture anyway is gone.

On article Leica M Monochrom now available in grayscale (sort of) (136 comments in total)
In reply to:

samfan: I just calculated that if I'd shot a roll of Tri-X every day, and had it developed and scanned, even the mono Leica M would pay for itself in just 18 months (probably sooner if you factor in the cost of a decent film M body).

Buying bulk and developing and scanning yourself - and the M pays for itself much sooner in saved time.

I don't know why are so many people so confused. Film is bloody expensive.

Sure, but so is this camera.

Link | Posted on May 27, 2014 at 00:07 UTC

This is neat, but I can't figure one thing out. Did they intentionally vary the exposure and shutter trigger time slightly, or could they not actually figure out how to synchronize the cameras correctly? I don't dislike the effect (it kind of goes with the theme of street photography), but I wouldn't mind if it looked more intentional.

Aside from that, it would be nice if this was a bit more than just a Microsoft / Lumia ad.

In reply to:

ozimax: Astonishing images. And just think, it took a Creator God to make these impossibly complex animals. He not only makes things work, He makes them beautiful at the same time.

Kudos to the photographer.

PaulDavis, this comment and a couple of the responses are akin to trying to show someone just how wonderful a perfectly baked pie is by throwing it in their face. Throwing beliefs (presented as truths) that can never be rationally argued in other people's faces is extremely disrespectful to whatever beliefs they might already have and rarely leads to any productive discussion.

I think that's a problem with the photographer, not the camera.

In reply to:

Karl Summers: I own a D610 and have had zero issues thus far. Just wanted to put that out there. Nikon makes a fine camera, they could use some lessons in PR and customer service.

Yes, the camera that was arguably released specifically to address the design problems with the D600 shutter. Nikon does generally make great cameras, but the D600 obviously had issues and a lot of people are quite understandably unhappy with the way Nikon handled them.

In reply to:

stromaroma: The irony is that Americans actually believe they have freedom... "One World", yeah right, this building is a great way to stick it in the face of the rest of the world that the Wall Street bankers enslave the world via the One Bank.

It's "One World Trade Center", as in the primary building of a complex proposed in the 40s, originally built in the 60s and 70s, and recently rebuilt. But go ahead and intentionally misinterpret the name.
