Even More Fun Pictures with Nikon

No spectacular mountains here, just gentle slopes... a -modest- miniature after classic far east paintings :

Here's two more. I took the first photo into Nik Viveza 2 and desaturated the tree trunks to remove the purple. They still look tinted on my MacBook Pro and they didn't on the MacPro! Screen calibration? Cheers, Matt.

1. D3; 200mm f/2; 1/200s @ f/4; ISO 1600
Very nice, Matt, and very interesting. I first looked at this on my MacBook Pro, and my first thought was that the tree trunks were a little purple. Then I read what you wrote, so I looked at it on my wife's iMac, and there is no tinting at all. Doubly weird as my MacBook Pro is regularly (including recently) calibrated, and iMac has never been. :eek:

Lloyd: My MacPro was calibrated a while ago and there's no purple. Maybe, i'll try calibrating them both again. I use a X-Rite ColorMunki. Interesting to see what it does. Thanks for the comment. Cheers, Matt.
Very interesting. I use the ColorMunki as well.

They look a bit purple on my monitor but it's a beautiful shot nonetheless.

Thanks Alex, Matt, Lloyd :)


Matt-
Regarding the purple question, here's my take. Except for end-to-end controlled graphic chain calibration -say, from one monitor to one printer- and light, there's no absolute viewing parameters. Despite the industry efforts (and marketing ) in calibration tools and profiles, the diversity of equipment, supports and conditions have us living in a world of compromises color wise. Nothing new in this statement, but we have a fair example here following your and Lloyd's findings above.

This is why, when one really needs an absolute reading of values the only solid reference is the color picker. Though it's not a current requirement in general photography, for this purpose we developped some time ago a small piece of code allowing to graphically extract and display dominant hues in a chosen zone (using a few clicks of the color picker on the desired area, set @ 3x3 average).

Took the liberty give it a run on your photo, specifically on the two main tree trunks. Here's the result (sRGB jpeg):



I'll let you draw your own conclusions.
There's a number of things you can do with the file, view on your different monitors, compare the web display(s) to CS4's, make comparisons with your reference file etc.


On a sidenote i feel it's not uncommon to see trunks with this kind of cast under such light conditions. Especially with a green contrast, then to get back to monitors the perception is quite dependant on the relative colorimetric values of each display, even after careful calibration.

Sorry for the long answer :deadhorse:

And by the way, i personnaly very much like the photo as it is. :)

Notwithstanding, once again whether you feel it were a lens issue, i'd be glad to take care of the useless piece of junk for you :angel:

Matt, like the tree lines bringing you into a center point. Nice reflection also. A hint of purple on my Mac screen, but hardly noticeable.

Hey, thanks Steve, you're way too kind.
These last months we had to deal with terrible light conditions here, so i guess i' had try and learn to look at the lanscapes possibilities in a different way. I have more to come, C&C will be welcome...

Btw, don't you find that your own 200mm also have this dreadful purple cast? :mad:

(ok i know, it's just the 100th time i'm making this stupid joke) :eek: but i really want one :eek: :(

Just kidding, Steve, just kidding.

It's such a wonderful lens -though on the expensive side.
Corlan, i wish you told me earlier that you were kidding....I just bought an Expensive Spectrum Analyzer to check on the Purple Fringing & found a Significant Problem, but in the lower wavelengths of the orange spectrum! The lens has been shipped back to Nikon for repairs...:wtf::bugeyes::ROTFL::D
 
Hey Matt... I've got a tinge of purple on my Macbook, but frankly, this screen sucks. Regardless, awesome shot.

Corlan... classic shot. Just beautiful.

Nothing serious here. The girls were expecting a chicken snack...

David/Steve/Jason: Thanks.

Corlan: Thanks for the information. Great long answer. The color chart's pretty revealing. This coloring showed up before with my Eagle shots. That was a 300mm f/2.8 w/TC-E14. It's interesting that this is the only color variation from monitor to monitor that i've noticed (probably because purple is "unnatural"; unless you're in the Southwest). Sorry, That piece of junk, 200mm f/2, was transformed into part of my M9.

Jason: Nice dog shot. They're really elegant.

Cheers, Matt
