I just hope they stopped using sqlite as the database manager for Lightroom.
Since SQLite is the basis of the entire LR catalog system, I wouldn't hold my breath on that one either.

I've got some experiences with dbms, and for a single-file based db sqlite is blazingly fast though it lacks some fancy stuff of the bigger enterprise systems.

If Adobe want to speed up LR on that end, they have to exchange the whole backend into a no-sql custom solution. But I'm not sure if this would gain a lot, reading/writing a 1gb+ db is a bottleneck on its own.

The actual status of my 6D: It returned yestreday after almost 2 weeks. Camera works now basically. Changed the card-slot-board (if I have translated this right). But now, the main front wheel does not work. Sent it back again.... More to come

Argh, that's a good reason to have a backup camera. But on the bright side: They can hardly charge you again after sending back this camera as "repaired", so imho whatever should be the issue with the wheel should be on them.

because of the way EOS cameras meter for the background light in those modes, which is totally different from "P" mode, which meters for the flashlight.

It is?!? How so? I admit I never bothered to check since I use Av all the time (with min. shutter speed). Could you please elaborate how P ettl metering differers from Av/Tv?

Windows 10 will be out later this year as a free upgrade to windows 7 and 8.  Adobe needs to be working on support for that.
Well that'll be a first then...

No problem there - Win10 is Win8 is Win7 is WinVista. They all use the same code base, they did the big jump in driver design and security with Vista - which is one reason it was so unpopular at the time. Essentially, Win10 is Vista SP6 minus the Aero design plus "Metro" touch interface.

Of course Microsoft is happy to grab money again for Win10 re-certification, but it will be their *last* operating system: All subsequent improvements most likely are delivered as a rolling release, Adobe-CC like subscription, here we come.

when using an on-camera Speedlite please obey one most important rule:
ONLY EVER USE "P"-MODE
Never, never, never use Av or Tv mode ever, unless you know what you are doing!
P mode... you can't be serious. Maybe find the little picture of a smiling face, not the mountain or the flower mode... or better yet, find the green box.

Imho the idea of the P mode advice has its merits, even though it certainly doesn't have the nerd appeal and you cannot be smug in an Internet forum.

In my experience when in a pinch with a client, time pressure and unforeseen obstacles you only want the thing reliably done, grab the money and keep a good reputation. The very very last thing you care about is playing around with dof/shutter in fractions of stops.

Few clients care about what mode you used (it doesn't show in the picture, you know) or if the bokeh isn't as smooth in one shot, but they do care about the photog not paying attention to them because he/she's busy with the gear.

Personally, I've automated my camera with Magic Lantern as far as possible (even writing my own auto_iso module which unlocks flash) for automating repetitive tasks, but the best advice there is to have a wide range of choices and select the appropriate one. This includes the compromise P option and using original Canon gear instead of 3rd party manufacturer clones.

I use the Colorchecker Passport for all event work with mixed lighting... make a DNG dual profile and use it for every shot in the same area.

It's a good option, but I found that constant lighting (esp. wb) is paramount - or color checker is next to useless. It's not like it's "nice to have", but you could also just shoot a cheap gray scale to get a hint for the color dropper.

So my question is, is white object and grey photo from expodisc really is the best reference for white balance?
or I need to trust my vision (to identify color cast and adjust accordingly)

Personally, I find that the "correct" wb can look very awkward depending on the setting the viewer is in. Summer noon, sunset, ... can have wbs that look plain wrong to me.

I have some experience there because I shoot gray horses a lot, and boy, you cannot imagine how different gray looks there are over the year. So if shooting outdoors, setting a "subjective" color temperature and then adjusting the tint accordingly often looks more natural to me.

For some reason I like natural lights instead of using the flash.   

I suspect what you actually dislike is *visible* flash, which qualifies as over-flashing unless there is too little ambient. Good flash exposure is next to invisible unless you're a photog and are determined to look for it.

Also another question I have is how often a professional photographer use the Shutter Priority mode to capture dancing,   like when the couple playing games, dancing......etc.   Should I use TV mode to get better shots.  I know AV will get you depth of field but I just want some clean and clear shots.

It doesn't matter, you can dial in the flash/ambient ratio in either tv or av mode. The most important thing to remember is that in all these modes, even in p or camera m, you're relying on the in-camera metering if you flash with ettl.

If you want consistent exposure in changing light situations when there is no time to repeat shots if the camera has got it wrong, the one option is to use camera m *and* flash m. Problem: You need experience to set this up w/o endless trial & error, that's why good photogs are paid for what they do.

Technical Support / Re: Zoom ring on 17-40L becoming loose?
« on: January 21, 2015, 03:07:28 AM »
Lift the zoom ring rubber up and pull it off, then you will see there are 2 holes on the zoom ring. There is a screw in each hole, use a JIS 00 type screwdriver to tighten them up. Put the rubber ring back and you are done.

Thanks a lot, I'll do that - I never imagined you could pull off the rubber just like that!

Technical Support / Zoom ring on 17-40L becoming loose?
« on: January 20, 2015, 04:31:51 AM »
My trusty ol' 17-40L is developing a potential issue and I'd like some feedback if there is nothing to it or if it's a sign of impending doom(tm):

The zoom ring (the one towards the camera) has a bit of play, i.e. I have to turn it a bit before it grabs the actual focusing mechanism. I cannot remember anything special happening to the lens except my usual heavy duty outdoor usage.

Atm, this is not problem at all ... but if possible it would be nice to have experiences on how this will develop in the future - either stay this way, becoming a bit worse or completely breaking the lens requiring expensive servicing.

Thanks for any insight!

Does anyone know if/where you can purchase Photoshop CS6 Extended?

Beside buying new, if you don't want a subscription you can buy a used license for CS6. But looking at CC's improvement list in PS and the speed they're developing, you might miss a lot if you're stuck with the old version.

EOS Bodies / Re: NEW CAMERA - EOS 80D?
« on: January 09, 2015, 12:07:16 PM »
The 70D moved upmarket in terms of capabilities but not in terms of price.

I don't know about that, imho the 70d stayed in the same market segment, but the technology simply evolved.

Actually, if it's really a new rebel with the 70d sensor in the promo shot, you might say the 70d moved "downmarket" as there might not be much space left in between them except the camera size and sturdiness... which is the reason why Craig suspected Canon could dump the xxd line altogether.

Personally, I think they'll continue to sell the xxd as it's the jumping point for aspiring photogs to more expensive (ff) cameras. A Rebel simply doesn't have the same level of usability, and an entry-level 6d might be still too expensive for some.

How about a smaller FF DSLR? a 6d sensor in 70D like body.

With a mirrored camera (prism & mirror size depends on sensor size in these designs) you can only go so small, and if you look at a 6d there's really not much space left to cut and it's already 70d-ish. Anything smaller would also severely impede the usability (grip size, button placement).

EOS Bodies / Re: Speculate: How much noise improvement from 5D3 to 5D4?
« on: January 09, 2015, 12:01:57 PM »
The only truly digital ISO settings (where the adjustment is made AFTER ADC) are the expanded settings, as far as I know.

It's really hard to tell, the ML devs really dug into it while trying to optimize the digic registers to get more dynamic
range "for free". There are multiple amps involved, and they work in different ways on each iso setting, currently my impression is that they won't be able to figure it out completely.

What it comes down to "digital" vs "analog" is if it's "worth it" dumping dynamic range for probably a tiny bit of less noise because the amplification is done in the image data chain. For most purposes, at least for what I do, the answer is "no" - I'd rather shoot raw 6400 underexposed than go higher on my 6d.

Imho there are lots more people out there cranking iso up w/o knowing what the tradeoff is, that's why I'm (and the ML devs, if you read the thread over there) are rather verbal about the minimal benefits of post-sensor amplification on high iso settings.

EOS Bodies / Re: EOS 5D Mark III Replacement Talk [CR2]
« on: January 09, 2015, 11:50:13 AM »
Its a Chinese language problem. Its irrelevant if it comes first or last as you want to avoid the sound itself.

Its not going to be a big problem if a Japanese Camera company calls a camera something with "4" as the Chinese will associate it with a foreign product anyway (and thus be more forgiving). They could also just give it a proper Chinese name for the Chinese market as the hotel chain Four Seasons did. There are good reasons for doing so with a lot of products anyway just think Coca Cola.

Thanks, that's very interesting! What's your take on Canon skipping the Powershot then, are they jumping at shadows or is a Japanese product maybe not considered as "foreign" (because it's Asia) as an American one - no matter Nikon going ahead with the D4?

EOS Bodies - For Stills / Re: Preparing for the switch
« on: January 09, 2015, 11:39:56 AM »
In theory, f/2.8 should compensate for the IS on the f/4 with a faster shutter speed

Not so. I cannot give you a lens' owners comparison, but I can definitely say that IS is worth much more than the f2.8->f4 difference in terms of lens shake. Alas, with IS, it's all about statistics and your result will differ on consecutive shots - plus IS needs a short "swing in" time before it's effective.

So the real question are f2.8 vs. f4....
1. stopping power w/ faster shutter: do you shoot motion?
2. thin dof shooting
3. bulk: do you want the more portable f4 w/ built-in macro mode?
4. af speed (the camera always af's wide open)
5. future outlook redundancy - will you get some really fast f1.2/f1.4 primes sooner or later?

However, looking at your other lenses and general budget probably the f2.8 is the way to go as it has the best possible performance. Esp as you've already got the wide angle IS side covered with the 16-35/4.

"4D" is possible
Not so: 4 is a no-go in Asian markets, just as there's no PowerShot G4. There's even a word for it :-) " tetraphobia": https://en.wikipedia.org/wiki/Numbers_in_Chinese_culture#Four.
So...please explain the Nikon D4 and D4s to us.  Is Nikon not a Japanese company?  Is Japan not part of Asia?  Are Nikon just very brave to flout a public phobia, whereas Canon is too cowardly to do the same?  I look forward to you sharing your cultural wisdom on the subject...

Sure, everything you ask for good ol' Neuro, inquiring in the usual friendly tone :-)

On close inspection, you'll notice that in Nikon's numbering the 4 is *after* the d, while with Canon it would to be much more prominently up front and the whole name probably more pronounced like "death" (native speakers around?).

It probably depends on a company's specific marketing strategy how much they consider these local specifics, it might be more important for consumer-grade products (like Powershot) than flagship (like D4). And it'll matter if you have to actively skip a number or can easily avoid the problem altogether with a new product like "EOS 4D".
