i1Profiler - Publish on a PC crashes too
by andy.williams＠wan-ifra.org 20 Jan '12

20 Jan '12

I'm using i1Profiler Publish v. 1.2.0 on a Windows XP platform. The program has also crashed a number of times, without an apparent cause. I like i1Profiler Publish with its fully integrated interface. I used ProfileMaker 5.0.10 with its modular approach before. I miss the ability to enter an ISO greybalance but appreciate that it's an "open door" with a strong possibility of being adjusted badly. I would also like a multicolour 3-D display for the profile gamut. A monochrome green display went out of general use in the mid-80's. I'm also experiencing problems with recognising an X-Rite iSis XL spectro the USB interface, even with the iSis switched on at the time of connection. The latest USB driver seems to not be installed at the same time as the new i1Publish software - but this is a minor problem that can probably be easily solved.

Ich darf dann mal A Sanna zitieren, der sich am 16.01.2012, gegen 16:34 Uhr -0600, folgendermaßen äußerte: >Does anyone know the Pantone digital library LAB value for PMS 4975? I've got a draw down here (that doesn't look like the swatch in my book) with a reading of L*16.82 a*18.21 b*8.62. The values of the actual Pantone Swatch Library "PANTONE+ Solid Coated" for the Adobe CS suite are: 16 | 15 | 7 There ist the download: http://www.pantone.de/pages/Pantone/Pantone.aspx?pg=20721&ca=1 MfG Thomas

DeltaE Calculator

Greetings, I few corrections to my last post - sorry and thanks Mark for the heads up on the link. To find dE difference calculator and other very helpful calculators go to Bruce's website: http://brucelindbloom.com/ Click on the calc button and then on the calculator you are interested in. For instance click on Color Difference Calculator and once on the calculator page you will see a link to an HTML version (not an app as I previously indicated) that will allow you to use it on an iPhone - thanks again Bruce. I have also found the CIE Color Calculator very helpful. -Bill-

Re: Viewing DNG Metadata

Iliah, Robin, Andrew, Thanks for the responses. They were all helpful. Iliah, I did download RPP and played around with it. I'll need to dig in a bit more before I can really make sense of it. I downloaded the other program too, but my brain turns to fluff when working in Terminal mode. Andrew, I was under the impression (perhaps incorrectly) that LightRoom always updated metadata *automatically* after every change and wrote that to the DNG file. On my system (at least when not sharing files with others) that's how it seems to work. I am hoping your suggestion will help, because I am fairly certain the other guy is NOT doing a "forced save" (Cmd-S) before sending me his DNG files. I'm not on my end either. So, we will give that a trial and see if it solves the problem. I'll let everyone know what I find out. I'll bet Cmd-S does the trick! Thanks again, Lou

Not Andrew, but it only does that if you set the automatic updating in your Prefs. Bob Frost -------------------------------------------------- From: Louis Dina

Is there a calculator or utility out there that could generate the DeltaE between two entered Lab values? Tony -- Anthony R. Sanna SACO Foods, Inc. 1-800-373-7226 asanna(a)sacofoods.com

Viewing DNG Metadata
by Louis Dina 17 Jan '12

17 Jan '12

I am trading some RAW DNG digital camera files back and forth with a friend, and for some reason, some of the metadata is changing, notably the custom camera profile shown in the LR/ACR Calibration tab. What is being sent is not being read or displayed when imported into LR. So, I want look at the full metadata in the DNG file without opening the file in Photoshop, ACR or Lightroom. This may be caused by default settings or preferences, but being able to view the file outside of Adobe software should at least establish what is written to the DNG file. I'm currently using OSX 10.6.8. Are there any native OSX tools that will allow me to do this? If not, is there an easy to use, free utility that will allow me to view metadata? Thanks, Lou Dina

PMS 4975 LAB Values
by A Sanna 16 Jan '12

16 Jan '12

Does anyone know the Pantone digital library LAB value for PMS 4975? I've got a draw down here (that doesn't look like the swatch in my book) with a reading of L*16.82 a*18.21 b*8.62. Also, I have a Digital SwatchBook (DTP22) that's still plugged in and still works. Do any of you know of a program that I could sample colors in. It would be nice to be able to take a reading from my swatch to compare values. Tony -- Anthony R. Sanna SACO Foods, Inc. 1-800-373-7226 asanna(a)sacofoods.com
