.....

You don't. You just test print until you get something that closely resembles what you want!  :P

But seriously - you can talk to the lab and ask them how to go about it and what settings you should use etc. they might provide you with an ICC profile for your monitor.
Spend enough on PC hardware and software and you'll no longer go through through test printing anguish.
The sequence becomes soft proof>print>smile.
See my post above.

.......Then there's another question: printer calibration. I don't plan to buy a printer, any eventual printing services will be carried out by a specialized provider. How do you know how and if their printers are calibrated properly?.........
TL:DR version...
Ask the service for icc profiles, if they have none to offer (or seem clueless), find another service.

As I understand it, printers are not calibrated in the sense that actual print output capabilities can be corrected, a printer can only print what it is able to.
 
Printers can and preferably should be profiled.
Profiling should be done for each specific printer to be used and with the specific paper and ink set to be used.
To profile, PC installed profiling software sends a print job to the printer, this print job consists of many different colored squares over a couple of pages.
The resulting printed squares are then scanned/read with a color measuring device, the Datacolor SpyderPRINT calls theirs a Spectrocolorimeter..
The printer was unable to reproduce the exact colors sent in the print job, the Spectrocolorimeter measures what colors actually did print and then generates what is essentially an error file.
This error file is named with either an .icc or .icm file extension, it is the printer/paper/ink profile.
SpyderPRINT prints 225 or 729 different color patches on 1 to 4 sheets depending on options selected.
 
The better print houses provide icc files for download as do printer manufacturers and paper manufacturers.
 
To use, install the appropriate profile to your PC, then, in your image editor use soft proofing>print emulation, choose the relevant profile for use while editing.
 
The final print comes out pretty darn close to exactly as you intended and expect.
 
I've only done this a few times with various papers and images, I've gotten exactly what I wanted on the first try, no wasted paper or ink, no disappointment or guesswork wondering what or how to tweak.
 
I'd sure not expect any of this to work well without a calibrated monitor.
- - -
There's another method that I've read of but not tried that involves loading and selecting icc profiles directly to the PC's monitor color settings.
My imagination goes to overload trying to reason how a monitor can be both calibrated true and use another color profile simultaneously.
I believe it's also much faster to switch profiles in software rather than hardware for A<>B/before<>after comparisons.
Somewhere in the literature that accompanied my NEC monitor was a comment to the effect it's preferable to use the soft proofing method rather than icc profiling the monitor by I cannot recall why nor find the document right now.

Any time I experience corrupt files on a card, that becomes the absolute last time I'll use that card.

Replacements are not at all that expensive, the super duper highest speed cards are overkill with a 6D anyway.

EOS Bodies / Re: 6D firmware 1.1.6 exposure issue
« on: February 19, 2015, 12:39:24 PM »
Have you tried resetting the flash from the on-camera menu controls?
On camera, press the MENU button, scroll to the far left then back one to the right, second listing is "External Speedlight Control", bottom left is "Clear settings".
Do this with flash attached and switched on.

Some copy/pasted specs......
---
Operating Environment

Canon 1Dx and 7DII

Working Temperature Range
32-104°F/0-40°C

Working Humidity Range
85% or less
---
Pentax K-3

Operating temperature: 14-104°F (-10 to 40°C)

Weather resistant: Yes (92 special sealing parts)
---
I expect such specs to be somewhat conservative in that you can still expect some performance when operating outside those stated envelopes. Exactly how far beyond spec will vary by unit and use/care case.

As silly as Kai often is, you may find it worth your time to seek additional quotes of the photographers he quotes in this video.

Yup, using BBF.

In a B&H video on photo editing work flow that I saw a while back the presenter suggested spending the absolute minimum time on rejects, one glance and move on, don't even bother rating them. Once you've viewed a set, delete everything not rated.
 
As I rarely shoot action, I rarely use burst. With adequate light I trust to my skills and the camera's capabilities to get a good shot, I do chimp a lot just to be sure.
With low light and slow shutter speeds I will shoot short bursts up to 4 or 5 frames assuming that there will be some camera movement as I press the shutter while hoping that I and the camera will be still during the duration of at least one frame.

Seriously, don't burst unless you really need to, trust to your judgement, skill set and gear.
When culling later, again, trust yourself, pick what first appeals, dump the rest.
If shooting for a client you'll want to cull looser so as to meet the client's specs with a few optional choices.

.....If you didn't have camera, would you still the pc?......
If I didn't have the camera I for sure would not have this PC, this PC having been purpose built to support cameras.
Most everything else I use this PC for could be done almost as well on a tablet, for sure on a far less elaborate machine.
So where does this PC fit then? Part of the camera's cost or an accessory? Or maybe cameras are PC accessories?
 
Just questions, food for thought. Sure not trying to challenge anyone nor get anyone's dander up.

26
Where does the cost of the PC and its software load factor into the question?
Is the PC a part of the camera or an accessory?
 
I'd argue that since a digital camera is pretty much useless without a PC for file management and editing, the PC is part of the camera and skews the camera's cost much higher than the body alone.

Yet, obviously, a PC does so many more things than just support a camera.
And to counter that ^, my current PC as well as those of many others here on CR was purpose built to support cameras, everything else the PC is used for is frosting.
 
I'd not count a commodity PC's cost as part of the camera if it's the sort of PC that struggles with editing, color management and such, that'd be a basic home use machine that just gets by.
Purpose built, yeah, part of camera cost, but is purpose building and accessory in itself?

Does DSLR Controller's focus stacking not meet your needs?

EOS Bodies / Re: Mirrorless vs. DSLR
« on: February 05, 2015, 12:59:29 AM »
Wait wait wait wait wait wait wait!  DSLR's and cars both have mirrors!!!
And:
wheels;
shutters;
apertures;
lenses;
gauges;
meters;
idiot lights;
actuator motors;
sensors;
displays;
buttons;
knobs;
levers;
switches;
doors;
circuits;
processors.
 
Anyone hoping car/camera analogies will go away, you might want to think about getting over it.
Last year's model is so, last year (car? or camera?).

Cameras ain't gots no pedals though.

the attachment is broken for me. cant access the image you attached.

I see it just fine.  It is just a simple .jpg... I guess I can upload it to dropbox or something.
'twas a site glitch, it's fixed. Your attachment works like normal.
