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

The Squire: What the 'eck is '4K enhancement'? Is it 4k resolution or not?

From the comments below it sorta sounds like its doing 2160i rather than 2160p!

@String I said UHD screens rather than beamer for a reason ;)

@String Yes, for movies anything better than FullHD may actually be good enough, considering viewing distances and a moving picture.

However, this being a photography site, I guess this Epson "4k" beamer is a big letdown when displaying still photos compared to true UHD screens.

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.

Shouldn't LED technology be able to solve this? 40W LED should output 2500 lumens already. So, why no 10000+ lumens LED beamer?

Thanks for the additional info. I looked it up again and this is from the 1080p native resolution footnote:
"4K Enhancement Technology shifts each pixel diagonally by 0.5 pixels to double the resolution and surpass Full HD image quality. Resolution is 1920 x 1080 in 3D Mode"
At best, this would be 2.7k resolution. But because of subpixel overlap, the effect is mich smaller even, I guess more like 2.2k. A very modest step from 2k. And nowhere near 4k. Therefore, the title remains being wrong.

DualSystemGuy: Too bad it's not actually 4K. They are playing the same games as JVC. Epson makes phenomenal projectors though.

Lamp life is still horrible on all models except those with LED/Laser light sources.

On article Photoshop CC 2015.5.1 available (89 comments in total)
In reply to:

Barry Bloom: I don't understand why every time there's a new Photoshop CC upgrade someone has to bring up the subscription service & how they use alternative products - we do not need to revisit this issue each & every time. If your are using Capture One and/ Affinity Photo (both are excellent programs) why do you feel compelled to post here? - there's an easy solution - use what you want & leave the Photoshop service to those who prefer it - leave us alone. Thank you

Some of the people complaining actually DO use Adobe CC.
They are just fearing that subscription increases to 49$/mth which is what Adobe had in mind initially and still try to enforce over time.

Unlike Damien's wrong title, this is no "4K home projector". Nor is it 2160i.

It is a plain 1080p projector. The only difference to other products is that it negotiates (and accepts) 2160p input via HDMI which it then downscales for display. It is normally a much better solution to do the downscaling at the source, or select downscaled input material to start with. It is even a bad choice with sources which upscale to 4k ...

@Damien Demolder

please rectify title and core message ASAP! As this is, as Epson states themseves, a 1080p projector.

falconeyes: I wonder if US citizens are aware of how ridiculous their legal system now looks to other parts of the world?

In my mother tongue, the idea of a "state of justice" is so important that the corresponding term "Rechtsstaat" became a part of other languages too (cf. https://en.wikipedia.org/wiki/Rechtsstaat ).

It is a corner stone of democracy and it is quite obviously (to people living abroad at least) broken in the US.

Especially in our times of competing civilizations (West vs. Arabic vs. East), the broken legal system of the US causes tremenduous damage to all of us.

@Steelhead and Steve: a rational state is not based on (a few) men's thinking. Maybe, follow the link.

AlexCHStudio: Oups.. Highlights on the 3rd picture do not look very attractive... I guess I would rather skip this lens. It does not really add anything into my collection of glass.. Still a terrific piece for those who does not have yet lens of this class.

Best illustration of cat-eye oof disks for 105/1.4 is this image:
-> http://pictures.digitalrev.com/image/upload/w_1400,c_fill,q_60/v1469767041/fvnayhqngvblwkexyyeb.jpg
The power distribution and color fringing of oof disks are excellent.
The cat-eye shaped disks must happen with every 1.4 lens, the more the longer the FL. The mount diameter just allows to let the center beam enter unvignetted. At F1.4, all other beams are vignetted to some degree. Math is simple enough to do by everybody.

@DukeCC
I suggest to follow the link. This has nothing to do with citizens' rights.
And Highsmith vs. Getty isn't about citizens' rights anyway.
Among others, my link (which points to an Australian professor) discusses the amount of power which should be given to judges and consequently, to lawyers. An unrational state is *no* unavoidable side effect of liberty.

Regarding the German aspect: maybe it is the fact that this country has experienced a collapsing democracy the hard way that its people are a bit more aware of alert signals if things go wrong.

Mikael Risedal: Nikon D1 1999 was the real game changer, the same year or year before I was offered a Kodak for 180000 SEK at Photokina by Kodak, normal price 250000SEK .
D1 was the camera which changed the face of the digital SLR market BUT this is more than 10 l years back, and what a fantastic advertisement for a certain company that rents out camera equipment in USA .

I agree for the advertisement. But it is deserved advertisement because their blog content often outperforms anything available from the large outlets, esp. when it comes to the optical performance of lenses.

Unfortunately, this is not what they claim.
It is their current favorites list (and a rather predictable one for gear heads), not the last decade's one.
The 5DmkII is the only gear which isn't a current product.

This is a rather recent speech from a Sidney professor. It sort of explains why the current US system (rule of law) does not intend to produce a "rational state".
P.S.
Not meant as reply to the previous post (wasn't there when I posted).
But fortunately, shows that some people even in the 21st century *DO* think about what may be going wrong here.

mermaidkiller: Fluorine coatings ?
Using the most aggressive halogen (which is a gas) as coating ?? F2 gas will attack glass instantly.
Probably fluoride (with a d) is meant.

OT: No VR for a lens of this price range ? Furthermore it should be an excellent low-light lens with 75mm aperture. Ideal for astrophotography when vignetting and coma at full aperture f/1.4 is not too bad.

Fluorine continues to confuse.
There is a good article about when to use which term:

falconeyes: This lens is a great addition to the Nikon lineup.
I am not obsessed with available 85/1.4 options and from the published MTF curves, this 105/1.4 should outperform them all.
OTOH, Sigma is currently field-testing a new 85/1.4 Art. It will be an interesting shoot-out between the two lenses. 105mm is just 24% more FL than 85mm.

I have no preference towards Sigma Art or this new Nikon. Both lenses will be heavy and good. I just hope the Nikon will excel as Nikon has some stunning glass out there (like the 200/2). Price is my secondary concern.

I once grabbed the oldest photon travelling thru universe, created right after big bang.
Does it qualify for a cover story too? ;)

I would have guessed that Adobe eventually enables cloud access for their poor CC customers on AppleTV.
I wouldn't have guessed they call this access Lightroom ...
