In order to validate that ICC profiles are not used in iOS4 basic apps like "Mail" (and "Photos"), just send to yourself an e-mail with picture with two different ICC profile embedded… one with Adobe RGB and a copy of this picture with a different ICC profile embedded (assigned) like ProPhoto RGB. You will see in Mail (on the iPad) that they look the same! Check this e-mail on you Mac with "Mail" app and will see that they are different! Hope this is more clear when I mentioned that color management is not implemented in iOS4, like it is on Mac OS X. Louis Dery www.couleur911.com

Monitor technology has advanced over the past few years, and you also have to consider aging of the older types of monitor calibrator. Currently X-Rite have a special deal offering a 'trade-in' discount on new calibrators if you return your old device, which makes this an ideal time to replace the instrument. This Trade In discount is listed at www.colorconfidence.com who deliver across Europe. So how to choose between the ColorMunki Display or the i1 Display Pro? In comparison to the old limited feature i1 Display-LT and the full feature i1 Display-2, the new standard level ColorMunki Display has a comparable feature set to the old full featured i1 Display-2 plus a few more features and newer filtering technology in the instrument. Whereas the new i1 Display Pro offers quite a bit more for QA and operates at 5 times the speed. If you are upgrading from an old LT model, I expect you will be satisfied with the new ColorMunki Display, whereas if you currently have the i1 Display-2 model, I suggest that even if you are currently satisfied with the feature set you have, that its worth considering the new i1 Display Pro, for its future advantages to you and for its speed. Finally, if you intend to use the instrument with 3rd party software, such as SpectraView Profiler that is supplied with NEC monitors (or Eizo Color Navigator software), then you should take note that it is only the instrument supplied with the new i1 Display Pro model that will be compatible with such 3rd party solutions.

Hi Jim, I am using the same iOS 4.3.5 as you for testing. About DropBox, if you use it to sync your picture to iPad, you will get different results compared to the ones I’ve showed on my web page, using iTune synchronization. iTune is doing a conversion if there is an embedded ICC profile in the picture. Dropbox leave the picture as is but does not use or understand the embed profile.

Hello Jan-Peter, I would be very happy to see WERE color management is happening in iOS 4 on iPad? All research I made (testing) with iPad colors, shows that there is no Color management for displaying picture in the Photo library browser of the iPad. I can show you "by-the-numbers". And this is why I reported this. I’ve been able to simulate accurately all color spaces (source, screen display, and output from Mail), you can read about it on my website. So, if there was a color management in place that reads ICC source and use it to display on iPad screen, sorry but I didn’t got it. Louis Dery ________________ Hello, iOS4 supports ICC based colormanagement, see also here: http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Refer… it took me 2 minutes to find this document through Google. May be we should do a little bit more research, before we are doing statements about iPad and color management in this list. regards Jan-Peter ________________

There is already one solution on the market for the iPad color management. The makers of Datacolor Spyder3 have compiled a program called SpyderGallery that creates a profile for the device. http://spyder.datacolor.com/product-ms-spydergallery.php Gerald J Skrocki www.gskrocki.wordpress.com On Jul 29, 2011, at 3:02 PM, colorsync-users-request(a)lists.apple.com wrote: > Re: Color Management for iPad?

Color Management for iPad…
by Louis Dery 29 Jul '11

29 Jul '11

Color Management for iPad… iOS 4.x does not have built-in color management support. BUT, there are some strange color conversions when you synchronize picture (with iTune) to your iPad. I did many tests in order to find a way to get better color accuracy for color pictures on the iPad screen. No!, the default color space to use for color pictures is NOT sRGB! Here is (link) a resumé of what I found (the problems) and soon, the solution! http://www.couleur911.com/ipad_color_management_en.html Let me know what you think about it !

Upgrading iMatch for Lion
by Sigurdur Armannsson 28 Jul '11

28 Jul '11

Hi everyone. I have been using Eye-One Monitor calibrator for years to calibrate several mac monitors at an ad agency, using iMatch. Now, when upgrading to Lion it's suddenly obsolite. On Xrites site there are some upgrades available but to tell the truth I find it a bit confusing. Like upgrading from what software, there is no mention of iMatch in the popup menus. So I though, why not ask those who already know: What should I upgrade to when I just want to have the features of iMatch? Thanks in advance.

OT: Supporting a color blind photographer
by Peter Miles 27 Jul '11

27 Jul '11

Hi there colorphiles Apologies if this is off topic, but here goes. I am a technician at a photography school. I am wanting to do more to support a photography student that is Red Green colorblind. Giving up on him is not an option I will consider. He is very determined to be a professional photographer. He has a great eye for composition and sense of lighting and bundles of get-up-and-go. But i see he will need a lot of support to work around managing color in his workflow. Especially as he leans toward portraiture. Has anyone worked with colorblind photographers / clients before? I have two main issues for me at the moment.. 1- I am having difficulty getting across to him the problem i am seeing in his color of his finished files. Of course he cant see it. So managing the color in his workflow is currently lower on his priority list than I'd like. Any suggestions? As for his tutors, I'm showing them Photoshops color blindness soft- proof preset with a few images to give them an idea of the magnitude of the issues this student is facing. Maybe there are other resources out there too? 2 - Software / workflow tools he might be able to use to help manage color. thinking Xrites colorcheker passport for his portraiture.. similar or other ideas? Your help with suggestions, thoughts or experience with this would be appreciated. Apologies for being OT Kind Regards Peter Miles

Is the NEC LCD3090WQXI still a viable solution?
by Steve Kornreich 27 Jul '11

27 Jul '11

Is the NEC LCD3090WQXI still a viable monitor for photography work? I already own the 2690WQXI and the spectra view software. I realize they have both recently been replaced with newer improved models and yes I know the New Eizo's are the way to go but I don't want to spend that kind of money. I see refurbished 3090 for under a $1000.00 now with a 30 day NEC warranty. Should I stay away from the 3090? Thanks __________________ Steve Kornreich http://www.kuau.com
