On BPG image format aims to replace JPEGs article (206 comments in total)
In reply to:

kb2zuz: Why is someone making yet another standard, we already have JPEG2000 which can save 16-bit files and no one uses outside of server applications where you want tiling and JP2 is better than a pyramidal tiff. We already have WebP which seems very similar to this standard and already works with at least some web browsers has and no one uses it.

The JPEG2000 standard isn't. There is fear that some of the libraries that leverage JP2 might have submarine patents... or at least that's how members of the JPEG2000 committee described it to me.

Edit also the patent argument is Something that has been said for 15 years... that argument may be moot at this point if the concerned patents predated it by a couple years.

Flashback: Please, please, please put this sumptuous sensor into a compact mirror-less body.

I really don't care how much it costs!

Depends on the lens and the design. A longer focal length lens will not be as much a problem, and wider angle lenses won't have as much issue if they use a retrofocal design. However a non-retrofocal ultra wide angle may have some issues (some of which can be corrected for light light fall of and color shift) but softness may well be an issue (though some people will be find with that).

nerd2: Color filter in digital era? We still need polarizing filter because the sensor does not record polarized information of rays but we can simply change WB (or apply a color filter) to get the same effect.

Just a Photographer, read the description. It's a Polarizer and a Warm-Up filter in one: A spokesman for Lee told DP Review that the warm-up element of the Landscape Polariser is the equivalent to adding an 81A warm-up filter. They were asking about COLOR filters, not ND.

Yes ND and polarizers are still useful filters, but that's not the question being asked here.

ScottRH: The D810 looks like the body D700 users may go for since the FPS is up. It should not take long to see if all of the D800/E issues are fixed.
But then again, a D710? !

I'd more expect a D900 in a year or two… a baby D4 like the D700 was a baby D3.

The reality is that only a handful of people will buy a $3,000 camera every 3 years. Which is why Nikon and canon flip-flopped between markets. The 5D Mk II was aimed more a studio and landscape photographers while the D700 was a sports/wildlife photographer's dream. This generation the 5D Mk III is a sports/wildlife camera and the D800 is more suited for studio/landscape. The D810 just says Nikon isn't ready yet to make a completely new camera, but they can make some improvements to the D810 that might satisfy some of those who are now waiting for a replacement of their 5 year old D700 (and can't drop $6,500 on a D4s)

Retzius: Nice camera. However, I must say the latest releases of digital cameras are getting awfully expensive. Even for an admittedly pricey hobby, the cameras and lenses released within the last couple of years really are pushing the boundaries of "affordability" for the amateur or hobbyist.

Cliff, I disagree with ruggedness as being the standard indicator of what is "professional." By that definition A $600 Pentax K-50 is more professional than the Hasselblads we use in the studio here. Not every photographer has the same needs.

I find that the controls tend to be more consistently what a seasoned professional shooter will point to when comparing a camera they feel is "less professional." Many cases ruggedness is needed by a professional and the camera that is more rugged will feel more professional. Obviously their are several factors in the decision and ruggedness can be one for certain people, but it's hardly a consistent one.

Falko: While Nikon's traditional fan base may not be bothered by the lack of wireless, 4k video, 1080p at high frame rates, focus peaking or an articulated touch-screen, I think it makes the D810 look old fashioned before it's even out the gates.

And if it looks dated now, how's it going to look in two or more years during the typical lifespan of this product? Remember this is not a cheap camera and even now you can buy a Sony A7r with the same sensor size and resolution, Wifi, focus peaking and a tilting screen for two thirds the price...

Different cameras for different users. For many people the A7r is a much better camera. For me my D800 is a better camera.

ipecaca: Wich of these improvements couldn't be implemented in a firmware update?

Physically rebalancing the mirror, physically removing the optical low pass filter, and upgrading the processing chip are physical changes. The processor upgrade definitely is needed for the higher FPS. It also allows for more complex noise reduction for higher ISO without slowing down the FPS.

Some features like zebra striping in the video and the highlight priority metering probably could have been able to be implemented in firmware, but there is a chance that they needed the speed or features in the new processor to implement them (or these features might be designed into the processor so it makes it easier to do than it would with a firmware update). These probably could have been done in firmware.

sRAW probably needs the faster speed to crunch the numbers quickly without slowing down the FPS. Maybe the could have implemented it via a firmware update, but I'm betting there would have been compromises if they did. But I can't say for certain.… I'd say 50/50 chance.

lensberg: Looks like an incremental augmentation of the D800 / 800E ... Whether its worth it or not is anybody's guess... At least it seems like a better thought out product line implementation compared to the mockery of the D610 ...

And coming to think about it... why is there no 4K video capability...?! May not be used all the time, but considering the price point, it would be nice to be somewhat future-proofed in the video specs department...

Why can't Nikon introduce a new model with a brand new sensor altogether...? Or have Sony not licensed one out to them as yet...? I'll bet when the 5D Mark IV is out, it will incorporate a new sensor, image processor, AF module and 99.99% sure it will have 4K video under its belt...

Yes, it's an incremental change. You're crazy to think that Nikon is aiming for D800 and D800E users to sell their cameras and replace them with this. There will be a few, but the target are the people who've been holding out on the D800 because the fps was too slow or they wanted a few more video features (because Canon has the Magic Lantern hack), or maybe they were holding on to their Medium format digital a little longer. This will not sell as well as the D800 did initially, but it will allow Nikon to keep selling the camera and stay relevant until the next generation is set.

select: nice improvements, but the lack of 4k video, wifi and gps, is a shame for a camera that costs over 3k euros

Wifi and GPS in camera have inherent problems. You generally see these features in entry level and enthusiast level cameras for two reasons. 1) They often use more plastic in the bodies and they aren't as weather sealed, this is adventageous if you're trying to get radio signals through without the use of an external antenna. 2) If the features don't work perfectly an amateur/enthusiast is not going to care as much, the features are still fun. If however you need the features to work consistently and accurately, you're not going to be happy if they fail or are problematic while working on a paying job. Most professionals will prefer to use a separate WiFi adaptor that is more reliable (or use a physical cable in some case). Similarly for GPS they will use an add on antenna that has a clearer line to the sky or they'll use a separate geo-logger that won't drain their camera's battery.

viking79: Go price how much OLPF glass costs, and quickly see Nikon is saving tons of money not including any AA filter at all. Rough guess is a full frame filter is going to cost $100 US +/-.

Seems like a small upgrade, Nikon must be feeling a lot of pressure from the competition to push it out so soon.

It's not just about manufacturing costs (which you're estimating base on purchasing one for yourself through a specially vendor, they're buying in bulk and the price would likely be significantly less than half that). There's a lot of design work that has to go into a new camera. They designed their image processing around the old sensor with the AA filter and with the AA canceling filter, and in both cases with that. They also have to plan out and design the manufacturing line, get regulatory approval in every country they plan to sell it, pay lawyers to file patents, etc. This leads to a cost of million and millions of dollars before they sell their first camera.

Now the biggest issue is that it's practically guaranteed that this camera will not sell as much as the D800 did (because many of the people who wanted a camera like this already bout a D800/E and only a handful are likely to upgrade from a D800). So they have to make more per unit to pay off the development costs.

Marcelobtp, I agree with you. "Professional" is not a binary choice where this camera is professional and that camera is not. It's closer to a continuum where something like a D5300 has controls that are more designed for an entry level user. For an extra $300, the D7100 is far more professional in it's controls. The D300s has a few features and nuances with it's button layout that are even more professional (though slightly compared to the difference between the D5300 and the D7100), however there are people who will pay $500 more (and take a hit in specs like megapixels, dynamic range, and high ISO performance) for that improvement.

Yes some of those people are just hearing that it's more professional and want it, but most are people who need a specific feature or ability and will pay.

I could get professional results with a D3300, but as a professional that doesn't want the camera to get in the way, I'd probably just be more frustrated with the camera in use.

This is a more "professional" camera, not exactly intended for hobbyists. You can get a very good entry level DSLR like the D3300 for $600 (which includes a zoom lens), or you can get one with more professional controls an autofocus like the D7100 for $1,100. If you really want full frame, the D610 can be had for $1,900 and is a very good high-end enthusiast camera.

To complain this is not affordable for amateurs is missing the point of the camera. It would be like going to a guitar store and seeing the one high-end $15,000 guitar in a glass case and complain that the prices are too high while ignoring the rows of guitars on the wall priced under $500.

On Walmart sues photographer's widow over family pictures article (200 comments in total)
In reply to:

bob elkind: Why does the photographer own the rights to these photos?

If the photographer hired the Waltons as models for his photos, and the Waltons signed a model release, then yes -- the photographer owns full rights.

I suspect that the Waltons hired the photographer to photograph them, the Waltons did not sign a model release (why would they?), in which case the photographer does not own the rights to these photos.

Model release has absolutely nothing to do with copyright law. Model releases are only really needed to prove you have the right to use their image (particularly if say you were going to use them in an advertisement).

The only way the Waltons would have copyright would be if they employeed the photographer full time (as defined by IRS laws).

You take a photo, you own the photo. Unless you are employed full time (not on a contract) as a photographer working for someone else. Then that person (or company) owns copyright. Model release has nothing to do with copyright.

If they go ahead with it, then you should be able to get the original files taken at a WalMart portrait studio.

On Hands on with the Pentax 645Z article (660 comments in total)
In reply to:

Donnie G: Now this is the kick ass Pentax that I've been waiting for. Not some wannabe medium format pretender dressed in FF 35mm clothes, but the real deal at an enthusiast accessible price point. Ricoh! You done good baby!

But this is a medium format want to be. 43.8x32.8 is hardly full frame and noticeably smaller than real 645. It's a good step, and I'm glad they're mocking Hasselblad and Phase with their ludicrous prices for the same sensor, but true medium format, this is not.

KAllen: You will not need to go a D800 to ask that question.
I don't own MF digital but I would if I could despite all the comparisons people make with the D800 etc. It's not all about the number of blades of grass you can record But I can't justify it.
I wouldn't go the Hassy route all the same, the 1/800th of a second top speed kills it for my needs.

Different cameras for different needs. Our H4D-50MS is great in the studio for reproducing artwork, and blows away the D800. However if I'm going to a show in a dimly lit club, the D800 is going to blow away the Hasselblad. Different tools for different jobs.

stratplaya: Who manufactures the sensor? I didn't find that in the release.

Do you have a source saying with certainty it is Sony. There have been a lot of rumors saying so, but I would like to know for certain. All other sensor that Hasselblad sources for MFD are from Kodak or Dalsa. Phase One seems to be using the same sensor in their new 50MP CMOS and they only source from Dalsa. I can see Sony stepping in, but I'd like to see documentation before I start repeating rumors.

Hate to break it to you. The Hasselblad H line was partly made by Fuji. Look up the Fuji GX545AF.
