Digital BW, The Print

I'll be receiving one of the new iPads on Friday, and will put it through its paces to see what its color capabilities are. In the meantime, here's the background info on the currently available iOS devices and their color gamut.

David,

I have held off getting an iPad until this one, as the low res put me off.
So what's the state of play in terms of profiling the iPads ?
Do I need a Spyder for Friday or can I use by i1pro and how good is the
profiling and do iPad apps recognize and use profiles?

Txs,

Mike

Oh you have missed out on a wonderfully useful device... I too am interested in your question though. As I understand it, there is no way to alter the display profile for the device.

Okay, what am I missing here?  Just WHY would you want to profile an 
iPad--or any tablet?

Any time you are using it as a display and are concerned about colour fidelity

But if course that requires you to be able to manage the profile the tablet deploys (which I don't believe can be done at the moment)

And probably will never be addressed as Apple shows no interest. Up to 
the Android devices then to create a kind of color management.

The guys that hack Android devices to calibrate the OLED screens could
lead the pack and if necessary I see them implant ICC support too one
day, could be based on LCMS or alike.

Adding more; Firefox on Android has some CM:

Another route: the Ubuntu port to the (Android) Asus Transformer. Good 
ISP screen too.

Pretty sure anyone who knows code enough can get into the code of an iPad and change things as needed, just like on a Mac using the terminal program. Do searches for jailbreaking iPads and you will see a whole underground group of "hackers" who do all kinds of things to iPads, iPods and iPhones. I am sure somebody could just make an APP to do color profiling on an iPad (C. David Tobie?) I would buy that APP.

Been there, done that. See "SpyderGallery" for the iPad and the iPhone at the iOS App Store. It's free, but to profile your devices you'll need to have at least access to a Spyder3 or Spyder4 device. Now working on the Android version...

In contrast with the MP camera thread, with improving tablet display 
resolutions, where is the line crossed that my old eyes do not see the 
image improve and I want to have a (pocketable) 30" display with old 
eyes resolution? More and more there will be a division between the 
young and old, between mobile and stationary. The last group is growing 
in percentage up to 2035 over here, it is not different in the US and 
Japan.

I do not expect that image editing improves when less experienced users 
work on 10" displays in all kinds of environments. Not to mention the 
lack of color management. Sure there is a 40 MP Nokia phone to feed that 
image stream and I will not object to make a 3x4' print at the end of 
that stream but to consider it as a real alternative for what we have 
already? Anyway more likely that 99% of the images never will be 
printed. Which makes it off topic here.

I agree that paper prints will decline in quantity, especially with the iPad 3 as a portfolio. But an iPad 3 at 15 inches from my face (assuming I have my reading glasses on) can offer about the same visual experience a desktop display does from the desktop. And it has a built-in touch tablet, which is a tempting tool for burn and dodge work. As. For color management, I review all edited images in SpyderGallery before doing anything critical with them. For printing I still send them to the Mac first, but that might change over time if decent color control for output is offered for wireless printing...

It's not all going to be baby-boomers using desktops versus kids using mobile; the excitement amongst older photographers about iphoneography is quite amazing at photo events these days.

Yes, they are a bit soft, but that's about to change!

>>So what's the state of play in terms of profiling the iPads ?

The only app that currently does that (insert self-promotion warning here) is SpyderGallery, from Datacolor. Free for the iPad and iPhone. We'll know whether an update for the iPad 3 is necessary on Friday. 

>>Do I need a Spyder for Friday or can I use by i1pro and how good is the

Gallery only communicates with the Spyder3 and Spyder4 models. The profiling on iPads and iPhones currently makes them match each other quite well, and to emulate a desktop display reasonably well, for those colors the very limited iOS gamut can reach. We'll see on Friday whether that will automatically improve with the larger gamut of the new iPad, or if Apple has done strange things under the hood that will require an update to SpyderGallery to correct. 

Currently, due to sand boxing of apps under iOS, the calibration in SpyderGallery only functions within the viewer app (the Gallery...) in SpyderGallery. We hope to provide an SDK for other apps to use the profile as well, but that hasn't happened yet. There is this thing called "Android" taking up our development time at the moment. ;-)

The created profile is stored on the iPad,and used by our Gallery app for viewing images with or without color management, and with the choice of two rendering intents.

Ernst,
I think you are very correct. Lots of differences between young and old.. Largely I think and I'll say this politely ok...We old codgers have a pretty high standard.. and also a high expectation.. The younger group are far more flexible in their standards and expectations.. About a month ago I watched an out of town artist do a presentation to a couple of gallery owners.. He did the whole thing on an Ipad with them standing around him.. He was flipping images with his finger and sharing info about each.. They could easily go back and forth... I happen to do the reproductions on a few of these and they didn't look quite right on the screen.. It didn't matter.. Don't laugh it was sort of like watching 5x7 trannies fly around on a baby light table.. well if you squinted a little maybe... This is the first time I have been in a space quiet like that and I'll say I was surprised how well it went.. I think I was looking at tomorrow.. So stepping back an Ipad might be a great place to carry your portfolio around.....as long as it was acceptable.....and I think it will be.. Everytime I see someone using an Iphone  in think..."Beam me up Scotty"..  Anyway I think we need to try to stay with it as in some ways we can help shape it..

Also picture a bunch of people (art director, talent agent, client representative etc) sitting watching a studio photography session with iPads linked in so they can see the images being created by the photographer wherever they sit rather than crowding around the unwieldy computer display.  A selection is sent to the ad exec or client with ultimate sign-off authority for review and he or she picks them up via their 3G/4G/wifi network while on the road. 

It's not just about young versus old or high standard versus low standard. It's also about having technology open up new ways of working. 

The iPad is already a godsend for people like me that need to review presentations created by juniors while I am travelling.

Embrace. Apple's first attempt (Newton) failed because the technology wasn't there.  Now it's rocking!

Well the ARM technology at that time was good enough for my Acorn 
Archimedes desktop computers :-)  Further developed ARM technology runs 
all the mobile gadgets now including iOS and Android phones and tablets 
and much more. So it is not that I did not see it coming. I went from 
Acorn Risc Os to PCs Windows because the first did not have proper color 
management and up to date printer drivers. Going back to similar 
limitations is not a good idea.

Maybe embracing systems without color management is easier for people 
that are used to OS systems with flawed color management 
............just kidding. We will see, the customers that had their 
Apple/Adobe color management at default settings in best case and way 
off in worst case are more likely embracing the gadgets without CM, it 
will not become worse to untangle the CM knots then.

As a fine art digital print-maker I'm very interested in using the iPad HD at a viewing wall proofing small prints vs iPad live Photoshop image (1-1) at nearly the same resolution. I wish there was some other solution for color management of the display besides datavision.

DataColor will "sort of" profile your iPad. The "sort of" is that the only place you'll see the adjustment in display is in their photo browser app on the iPad. Once you switch out of that, you're back to the default color settings.
I've run the app with the profile and without, and there is a noticeable difference in color, but again, you're limited to a single app.

David,

Can I export the Spyder iPad profile back to a PC/Mac ? Then I could;

   - Soft proof with the profile to see / adjust for ipad gamut
   - batch convert to ipad profile for a bunch of images, save without
   profile (as the images are now in "ipad color space" and then I presume
   these images would display in any ipad app just fine ?
   - etc...

I guess what I am doing here is using the ipad like a printer (driver)
without profile support (i.e. QTR on PC for example), only the output is
the display " (see Ernest this thread really it on-topic for this forum :).

If I can get the profile back to my PC from the iPad, I am off to by a
Spyder tomorrow...

Txs,

Mike

No, actually, you can use SpyderGallery to "launder" images into a color correct state for placement in other iOS apps. See this article I just penned on the topic, for a bit more information:

Great that's a good workaround - but when you next rev the app any chance
you could also export the profile for us to use in PC /Mac apps?

Also have you seen much variation in iPad screen profiles within same
generation?

It wouldn't be a matter of exporting, we actually build it on the Mac or PC, and export it to the iPad. But its not a standard ICC profile, since there is no standard color management under iOS. So that profile would not be usable on the Mac or PC in the ways you are thinking of using it� I can see the value of having a profile on the computer so that you can batch process images and send them to the iPad, but thats not how we are currently doing it...

There is more variation between the screens in iOS devices than I would like to see, though less than with some lines of monitors or laptops. Enough that a custom, rather than a canned profile, is of value.

Okay, I'm not getting it.  We calibrate monitors in a controlled 
environment.


Similar to a print, the LCD is subjective when used under different 
light sources.  So, what's the right one?  Daylight, incandescent, LED 
what I now use), or fluorescent?  If fluorescent, which one?

It seems almost like judging color balance off the back of the camera LOL.

your eye is very good at adjusting for white point.  Just use the native white point of the display (and don't proof for paper white).

Well, the Datacolor products actually offer to calibrate your display in an absolute manner, for studio use, or in a relative manner, for uncontrolled use. Thats what our default for laptops is. And thats what we are doing with iPads and iPhones as well. Adjust (or auto-adjust) the bucklight as needed; and be aware than in bright conditions, something other than the display may control your eye's whitepoint adaptation, and bias your sense of color...

If the device is sufficiently brighter than the ambient lighting, and sufficiently large in your field of view, it will control your eye's white balance, and the color of your ambient doesn't  much matter (it would be nice to have it neutral, but its not critical). If the ambient wins out, just be aware that your eye may be biased, and this is not a good time to be making color critical decisions...

Similar, but with a much better chance of controlling your eye (unless you use a HoodMan Loupe), and enough larger that you take it more literally. Size does matter� my iPhone never looks better than when I put a Loupe on it, effectively turning it into an iPad, and shutting all other light out from my eye.

And for those interested in such things, this facility was released
in Argyll in January 2008 after a discussion about how to
profile remote displays on this (public) mailing list in December 2007:

So a free method is possible if you have an ArgyllCMS supported puck, 
most are.
