Do you get these exact (or approximate) values just with the generated DCP or do you have to manually adjust the image using the Camera Calibration or HSL controls?<br /><br />Thanks,Sandro Franchihttps://www.blogger.com/profile/17491941224416761205noreply@blogger.comtag:blogger.com,1999:blog-4730121889169004991.post-1829174235386965512007-09-25T09:30:00.000-06:002007-09-25T09:30:00.000-06:00Tim,the problem is that it is really hard to itera...Tim,<BR/><BR/>the problem is that it is really hard to iterate between patches in lightroom. I have not written about the strategy you should take either. First one needs to get the exposure, brightness and contrast right to be able to compare the color patches. The photoshop scripts do this for you automatically.Jao van de Lagemaathttps://www.blogger.com/profile/04853597371091364769noreply@blogger.comtag:blogger.com,1999:blog-4730121889169004991.post-47557496827403230832007-09-25T07:07:00.000-06:002007-09-25T07:07:00.000-06:00Jao,Thanks for that conversion info to convert rgb...Jao,<BR/>Thanks for that conversion info to convert rgb targets on ColorChecker into Lightroom percentage equivalents. Something isn't working in Adobe forum, hope it's OK to reply here.<BR/><BR/>It's nice to have something to double check<BR/>tests I did looking for Lightroom percentage equivalents for a 5C, 3M, 2Y<BR/>highlight and a 80, 70, 70, 70 shadow. Any reason not to calibrate to a<BR/>ColorChecker directly in Lightroom? Other than not being able to use the<BR/>script which would develop a better average? Seems like it would avoid any<BR/>problems that might arise if wrong profile was used in Photoshop.<BR/>TimAnonymousnoreply@blogger.com
