Lenses / Re: First Tests: Canon EF 11-24mm f/4L a Winner
« on: February 28, 2015, 06:29:50 PM »
It's a shame that most of the LR tests are done wide open only, since the tests are so good there. Let's face it. For the most part, people don't shoot 16-35 IS, 11-24, 14-24, etc. at wide open, but more likely f/5.6-f/11, so I'd love to see the lenses tested at say f/7.1 (enough to avoid too much diffraction but also to get more of a sense of landscape shot performance). (and when you do shoot f/4 and faster and especially f/2.8 and faster, wide open, you are not as often caring about the edges corners as when stopped down a bit)

True, they will likely be closer at f7/8.  But obviously the 11-24 is going to be bad-ass whatever, and likely better than the 16-35 f4 for instance.


It depends though. Its a myth that they all do the same at more typical landscape apertures. The 24 1.4 Mark I vs. Mark II vs 24-105 vs 24-70 II vs 24 T&S vs 24 T&S II etc. show a LOT of differences at landscape apertures. That's why it's too bad LR mostly tests stuff at wide open.

I remember when $1399 wouldn't even get you a 20D!

Business of Photography/Videography / Re: SmugMug or Zenfolio?
« on: February 26, 2015, 09:09:17 PM »
I used smugmug for a long time, but Zenfolio all the way. I switched a while back and it's much easier to do all sorts of things.

The one thing I GREATLY dislike about both is that both ban anything but sRGB gamut!!!! Grrrrrr!!! Photo peeps should lead the color management charge not hold it back and to out and out ban it even if a user 100% knows what they are doing and 100% wants to use it for some photos..... what next? Ban color, since B&W is more artistic? Leave it up the user, don't decide the art for them and think you know better. SmugMug seemed more dead set against allowing wide gamut and posted all sorts of nonsense praising sRGB in all cases at all costs. bah. Soon nearly every monitor will be wide gamut too (probably by 2018).

I use Flickr to host all my wide gamut stuff (which is almost backwards from how I'd want it, but what can you do).

Flickr gets images a lot more attention.

EOS Bodies / Re: Patent: Multi Layer AF Sensor
« on: February 25, 2015, 02:45:35 PM »
Does this mean we should be debating the DR of autofocus chips? :O ;D

:-)  They certainly seem to have DR on their minds.... I bet the R & D area has DR on their Coffee mugs :-)

Where did you see anything discussing DR in the patent?  I waded thru most of it and saw no mention of DR.

It can handle a wide dynamic range of lighting conditions for AF in ideal fashion, being optimized for both blaring sun and dim dungeons.

I mean seriously the fact that they somehow thought people wanted crop modes just for JPG, the fact they try to trick users into thinking that you get a free TC out of switching to JPG+crop, the fact that they consider it a brag that they managed to equal 5D3 dynamic range despite adding 50MP.... :'(

I guess this is the final push to get those trying to hope Canon would change, to give up and swap systems.

"the design priority of these cameras was to produce the highest possible stills resolution, therefore some video functions were sacrificed. "

The weird thing is that engineer in the other interview claims that they improved the video quality and got rid of the 1080p softness that had plagued prior Canon releases. So what is going on? SOmething is not adding up. And what does stuff like zebras or focusing aids have to do with stills? That is just marketing decisions.

http://cpn.canon-europe.com/content/education/technical/inside_the_eos_5ds_and_eos_5ds_r.do

More details given. For instance: "This can be combined with Auto Exposure Bracketing (AEB) to capture two, three, five or seven-shot sequences at different exposures".

Edit: I believe that we were expecting just 3...

Also:

"JPEG images are captured at the selected crop setting while RAW files are captured full-frame with the crop shown in DPP, allowing for fine adjustment afterwards".

Maybe the reason for max 5fps.

Hmm. That would explain it, but wow that would make the cropped mode a near useless joke!
The whole point was to get improved buffer, fps and storage reductions and they blew all three cases! (unless you actually shoot jpg only, in which case the buffer wasn't a problem to begin with and the storage space wasn't quite as bad either).

Such a shame. I've been a Canon shooter for ages, but man I'm starting my move. (owning super tele makes it very tricky though since I got themback when they were 'cheap' so I may have to do it piecemeal and start with a hybrid Canon+Sony mix for now before managing to go to Nikon, speaking of Nikon they should put 100% of engineering into making an EF mount version  ;D)

"The sensor’s design also enables the EOS 5DS and EOS 5DS R to offer the same wide dynamic range as the EOS 5D Mark III."

Looks like someone is hoping to land a job as script writer for a sitcom.  :'(


(on a side note, it's odd that they go on about noise reduction at high ISO and improved sensitivity but then declare the ISO range to be 2 stops lower, 1 stop could be due to 2x MP count and viewing at 100% view but what about the other stop?)

Should help. I noticed that while say the 40D had better AF than the 20D for night soccer it actually often did worse under intense southern near noon sun, like they could only tune it for darker shooting and it would get overflow if it was too bright and opposite regarding the 20D.

EOS Bodies - For Video / Re: A Suggestion on the EOS-1D C Replacement [CR1]
« on: February 23, 2015, 10:44:54 PM »
If we consider the rumor over a 18 megapixel camera, 12 frames per second, video 4K, double CFast card slot, it fits well in a hypothetical 5D Cinema.

Although I believe that Canon can limit it to 10 photos per second, not to eat the sales of 1D series. ::)

Except for the fact that a 12fps FF mirror box costs a lot of money and why does a cinema camera needs 12fps?

It's bizarre.

They apparently plan to give high DR to the 1DX2 but not the 5Ds?!!!!! or 5D4?!.

They give 12fps to a 5DC but lock 5Ds to 5fps in crop mode??

If it's all true, it seems strange. But in way that almost makes it seems true....

4K/5K is a bit of a mess right now. As I understand it, DisplayPort 2.0 needs to be brought on-line to fully support the resolution at 60Hz and up. Last I read, there is really no movement on the 2.0 standard yet.

Current 4K/5K monitors are using 1 DisplayPort 1.2 to get 30Hz and (2) cables to get 60Hz. Some monitors flake out if the cable is cheesy.

You have things a bit mixed up. It is HDMI that needs 2.0 standard to drive 4k at 60Hz. DisplayPort 1.2 handles 4k at 60Hz just fine (and only requires a single cable). 5k might require more than 1 cable even for DP 1.2 or HDMI 2.0 though, not sure.

It does seem like DisplayPort 1.2 UHD/4k needs a good cable. The Accell cables seem to work out best for UHD/4k.

The Dell 4K has a firmware issue- wake from sleep.

You can disable sleep and go to screen save instead.
Anyway, you can get out of most of the Dell bugs by something a simple as telling it to switch from DP connector to miniDP and back or DP to HDMI and back and then seems to rid all issues 99% of the time.

For me the bugs haven't been that much of a big deal and the upside is 10000000x greater IMO.

Is there a direct correlation between color bit depth and the color gamut?

absolutely none

I read that to enable a 10 bit workflow, proper hw and sw are needed, is it the same for 8bit+frc panels?

Yes, you need a pro graphics card and only some software (maybe) supports 10bit. It doesn't matter whether it is direct 10bit panel (almost unheard of) or 8bit+2frc 10bit.

10bit doesn't give you a wider gamut, it has nothing to do with gamut size at all, it just defines how fine grained the steps are from 0 signal to max signal. 8bits give 256 steps of gray from back to white (or black to max red/green/blue) and 10bit gives 1024 steps. You can have 10bits and smaller than sRGB gamut and 6bits and larger than AdobeRGB gamut. The gamut size is one thing and the fineness of the steps between colors is another thing.

UHD/4k are not the tiniest bit overrated, if anything, they are vastly underrated

It's the difference between something starting to look a bit like a print/magazine/slide/looking out a window and something looking totally digital/artificial/blocky/no detail/computery.

Dell UP2414Q is a good choice, the price has come way down, I think it's like $750 now

It has:
UHD (at 60Hz over DisplayPort 1.2)

a pretty wide gamut (wider than CCFL wide gamut)

internal high bit LUT for: internal calibration without banding; programmable primary locations so you can dial in perfect sRGB emulation modes for when you need that; it might be 3D because it seems to provide extremely linear and uniform calibrations even when tone response or gamut are greatly altered from native

programmable screen uniformity compensation

the LED backlight is direct current driven instead of the typical cheap flickering PWM driven LED backlighting

it has the new less obtrusive anti-glare coating

it is IPS (although this does have the downside of poor contrast ratios and faded blacks compared to PVA/MVA and such; one day we will get OLED in these monitors and then be truly set as that gives wide gamut with wide viewing angles with fast response with deep blacks)

It's the best photo purchase I've made in years. (If they made a 5k 27" versions that had all of these features that would be truly amazing (they do have a 5k 27" now but it lacks a number of the above features) as that would gain a bit more impressive size and show over 14MP at once instead of just 8MP at once.)

I used to use a NEC PA241W.
