Comments on: Brilliant Flower, Not-so-Brilliant Processing http://regex.info/blog/2008-08-05/899 Not a photo blog, but sometimes I play one on TV Fri, 05 Dec 2008 15:51:31 +0000 http://wordpress.org/?v=2.0.12-alpha by: Mike http://regex.info/blog/2008-08-05/899#comment-19174 Tue, 05 Aug 2008 11:55:12 +0000 http://regex.info/blog/2008-08-05/899#comment-19174 I think your red flower experience is related to gamut clipping in sRGB. The global exposure reduction is bringing the reds back in gamut at the cost of darkening the entire scene. You might like the result better if you use the LR HSL adjustments (saturation and/or lightness) to bring the reds back into gamut without effecting the rest of the photo.

I recently had some similar photos, reds totally blown on my MacBook LCD, even though the ProPhotoRGB histogram showed nothing was close to clipping. You're right, dynamic range doesn't seem to be the problem. Popped in to Photoshop and turned on proofing for my Epson R1900, turned on Gamut Warning, and very little was out of gamut. Switched to my monitor's profile and the whole image turned 'warning'. Sure enough, it printed great. Moral: cheap LCDs suck. <span class='jfriedl'>Indeed. I ran that image by the Lightroom engineer in charge of the color rendering, and yup, it was just my LCD. I should have known better before complaining (or, at least, I should have complained about the proper thing).

Well, I did write a book…. just not about color management. :-) —Jeffrey

Perhaps the Camera Vivid or Camera Landscape profiles would perk up the flower? I did some work on an orange flower and posted the results on my webpage. The profiles do tend to perk things up. Just a thought! <span class='jfriedl'>I did, and the results with all the new profiles were generally much worse than with the standard "ACR 4.4" profile. I'm not 100% sure that the problem isn't that the consumer-quality LCD on my MacBook simply can't show the details. (I have a relatively <a href='http://regex.info/blog/2008-02-02/710' rel="nofollow">high-end Eizo monitor</a> at home, but I'm on vacation now, so am stuck with the laptop.) —Jeffrey</span> Have you experimented with the new camera profiles form Adobe?

I ran down there and startled them, just to get an action shot." That's ok. If you ran down near the geese to startle them, they'll have had the last laugh - check your shoes. “I’m so mean… I ran down there and startled them, just to get an action shot.”
