On article New Canon EOS 77D sits between Rebel T7i and EOS 80D (50 comments in total)

@DPR: Why not just issue an aggregated single post for such 'stellar' triads of incremental cameras from Canon - arguably sharing lacks.
Of compelling new features, of attractive pricing, of 4k video in AD2017.

Thus we could all unitedly bash them at our hearts desires :-)

Half-empty jokes aside, Canon seems to continue distracting its engineers with questionable targets.

On article Stunning time-lapse captures the seasons of Norway (65 comments in total)
In reply to:

mezastel: This is an awesome set of timelapse compilations! I do wonder though, why has the author restricted it to a letterbox format instead of sticking to good old-fashioned 16:9. Is it because it provides more opportunities for cropping? Also I visited Norway a few years back and yes, it does look this beautiful.

Amazing beauty - and the work behind it!

Yet I deplore the wide apect ratio --too common nowadays and often artistically detrimental-- that has not rendered full justice to this impressive work. I wondered how much better would've been in a 15:10 or 16:9... ?

Neither the scenes (beautiful!), nor the human visual system benefit from crops much wider than, e.g., 13..18:10. Reason for the HDTV compromise on 16:9.

How about a 16:9 version?

In reply to:

Jostian: not even basic weather resistance :( got caught in a rain storm with my X100T and it got water in, and never fully recovered :) so I say now what I said then, would love a new X100xxx but must have some weather sealing... guess I'll wait and hope for another year or 2.

some sealing would be expected at its price points

On article Dell's 8K monitor goes on sale in March for $5000 (215 comments in total)
In reply to:

faterikcartman: Too often companies seem to make what they think they can hype to the market. While ignoring what users really want. I suppose there are users who will plant their noses a foot from this 32" monitor. But I rather not hurt my neck. Further away are you really going to see 8k resolution? Were I The Monitor King, I would be making a 4 or 5k --tops -- in this size, OLED, and brag about blacks, contrast, and uniform brightness. But I guess 8k is easier to grasp and market. Reminds me of megapixels.

"a 4 or 5k --tops -- in this size, OLED, and brag about blacks, contrast, and uniform brightness"
Agreed: 4K/32" and 8K/40" are ideal in DPI at 2-3 feet distance.

My take: Despite having a 4k/40" (VA monitor) + another 4k/50" (TV), my most used is an ancient 2.5k/30" IPS screen, owing to its 114% AdobeRGB. Milky blacks, low contrast, low res... yet solid colors, ok uniformity and reasonable DPI.

So... I'm waiting for 30-40" true HDR OLEDs, 4-8K...
Yet the GPUs, HDCP, DP and HDMI standard implementations are still lagging, particularly in laptops... see Intel's kaby lake at CES, or Apple's 'support' for 10-bit

migus: tantalizingly beautiful!

and yet, no hires pics, nor exposure data, anything to teach the rest of us... :-(

1) I respect any artist's IP (intellectual property is also part of my daily bread), not to mention the artistic results - beautiful!

2) Also I fully understand posting low-res only, even if others and i (amateurs with other income sources) may post full res. The final 'product' shouldn't always be a free download... potentially leading to starvation and then regression.

3) However, about the (lack of) EXIF and metadata i beg to differ.
I believe in the free access to education, unhindered circulation of knowledge, and the open publication thereof. This is arguably part of the 'give' side...

Rationale: The tools used by the artist to create these great images were possible only thru the intellectual effort of thousands of scientists and engineers across decades - and their publications, incrementally building upon each others' discoveries. Published and freely accessible to any young mind, wherever on Earth, however poor.

Life's an ever shifting balance between give and take...

i'd rather avoid re-inventing the wheel each and every time... incrementally experiment ABOVE the known state of the art

Standing on the shoulders of giants means IMHO that one could stabilize a drone (or rocket) w/o having to first re-invent control, calculus, algebra etc.
Sometimes it seems that the creative artists may have a more protective / proprietary mentality than the scientists and engineers (that actually provide the tools / means for bespoke creativity :-)

On article Woof! Sony a6500 sample images are here (364 comments in total)
In reply to:

eno2: I really don't like the Sony processing engine, colors are bad, NR is strong and sharpening is high leading to high artifacts at higher ISO values. Once again, the Sony JPG engine is one of the worst out there. :(

Those who care so much about IQ as to avoid JPG and take the pain of RAW 'development' may benefit from investing a few $ more for a 10bit screen, e.g., an oldie 2.5K that can be bought cheaply today:

"Of course, the ZR30w delivers in color gamut. Note that in the volumetric 3D plot, the wireframe plot is the ZR30w, and the solid plot is AdobeRGB 1998 - that’s right, we’ve exceeded the AdobeRGB color space. The raw data is impressive, the display manages 111.36% of coverage, the highest we’ve tested. In this case, we’ve exceed the manufacturer claims of 99% AdobeRGB by a notable margin. I have no trouble believing that HP's claims about 1+ billion colors are totally accurate - you have to see it in person to believe it. There are just some colors I'm used to not seeing represented very well; reds and blues especially, and the photos that I have looked at are spectacular."

Colors seem quite natural seen on a 10-bit pro screen with 115% AdobeRGB color space. And camera's WB is also finely tunable, to suit other tastes.

However, i agree about the importance of a good JPG engine - particularly at this price point. Asking users to shoot RAW is akin to telling the BMW drivers to build their own engines if they want 0-60mph faster than 20sec.

"what digital accumulation means" : pls. provide the relevant links... currently it makes no sense to me to compound digital accumulation with ISO 0 and oo exposure time

"A sensor with digital accumulation would be a true isoless sensor, with almost ISO 0 as base ISO and almost infinite dynamic range at base iso."

the infinite dynamic range is practically limited by the S/N ratio at the bottom (e.g., consider the shot noise), and the sensel integration capacity (and readout speed) at the top.

Irrespective of the above, the reduced 64dB of DR (10bit?) seems an artifact of the read bandwidth and the global shutter implementation.

migus: Such laptops, whether Mac or Win, are our daily workhorses - doing jobs too many to list, some essential to our digital lives.

Such a 1-3K$ machine is the *hub* of bespoke digital live, and hopefully more than just a phone/tablet on steroids with an attached keyboard.

In its corporate Alzheimeir aka. triumph of form vs. content, Apple has incrementally crippled this digital hub into a catatonic shiny bling.

Devoid of basic functionality and previous features, adding in stead questionable 'features', e.g., an OLED function bar (BTW, why not an OLED UHD HDR display?).

I'll just skip my free MBP upgrade and buy a more functional/connected Win laptop... for much less $.

after reading
http://www.theverge.com/2016/11/5/13523372/usb-c-macbook-adapter-donglelife-problems-thunderbolt

i incline for the 14" Lenovo hybrids, some with OLED display (unfortunately not 3:2)... Also i consider the excellent Dell XPS series, besides the new HPs... plenty of options, since i learned how to enjoy win10 w/o its 20+ spyware "apps and services" and Cortana :-)

While we get our MBP machines from our employer in any desired config and model, and, i was waiting for an update from Apple... no thanks!

I'll just get another Lenovo, with most (if not all) the ports I need - and also OLED display (deep blacks, few % less battery life for bright bgnds.).

My only regret is missing the productive 3:2 display (vs. Lenovo's 16:9), which currently seems available mainly from Apple and MS (Surface Pro).

Kiwisnap: Just....Wow.

Microsoft have out-Appled Apple!

No fan of MS here, but KUDOS for its Surface h/w !

3:2 screens are great for real work and for surfing...! Yet it seems that Apple and MS are still alone in the 3:2 ratio, while the PC industry is still peddling its 16:9 (error) screens for "productivity" :-)

Roman_93: In a time where the goverment is allowed to scan every part of private life (or simply does it...) it is kind of ridiculous to limit private people so strong.

"What if their high resolution camera can read what you have on your phone?"
Granted - a potential risk, and a noisy one at that. The drone battery will last perhaps 20min, hence its spying window.

OTOH, Google's/Android, Apple's/iOS, MS/Windows et al. (FB, NSA etc.) 'analytics & big data' windows are open for business 24/7. Ditto for each garden variety mobile app, from the millions today.

Not only do they collect your screen and other data, but also they share it (as in sell) with a few K other firms, mainly advertisers. Again, 24/7.
