I love my new D3! The thing I like most is that I actually feel confident shooting it in one of the auto-exposure modes. If I turn on the Active D-Lighting option, it does exactly what it says it will. Fab! The D2x always needed some compensation on bright days and didn't truly reflect a hand-held meter consistently with varying lighting intensities. So well done Nikon. I still think they could have put a small sensor on the camera that would automatically adjust the screen brightness with respect to ambient light.
I have run a few tests using a gretag card to try and get accurate (not necessarily pleasing) colours from ACR. With the D2x I had a couple of presets that would do the job nicely, I am getting a lot of variance on the D3 calibrations. Has anyone else created some presets for lightroom or ACR? I have Capture NX but find it very clunky for a high-volume workflow, I love the Auto CA correction (why can't Adobe do this rather than manual adjustment, I'm also not a fan of the nikon rendering (blues too pale, tinges of yellow etc)
Simon Please let me know how you work this out. I just read about acr calibration, using AcrCalibrator. I have a gretag card in my B&H wishlist. I would be interested if you get this worked out, and if it is worthwhile in your workflow. Please let me know. Gary
Right, I've had a couple of free days and 2 computers crunching the Simon Tildeman script (with weighting on skintones, as I mostly shoot people). The below is great for "bright" conditions, flash/sunny/bright cloudy, I haven't worked one for incandescent light and in shaded conditions where the blue sky is the only light source, this may need some adjustment (I have another calibration for that which works fine but I suggest that you eyeball it anyway.
OK... In ACR or Lightroom
Tone curve to linear.
Red..(hue,sat) - (-11,16) Green (hue,sat) - (-10,7) Blue . (hue,sat) - (3,-9)
These figures were selected after 16 different runs on 4 different shots. The lens is the 24-70 2.8N at iso 400
Subtle playing with the luminosity sliders and exposure sliders can produce fabulous images and of course, turning up the vibrance and saturation slightly turn accurate colours into very pleasing colours for hnon-people work.
Thanks Curt, they're not a million miles apart. There are different scripts out there. Thomas Fors, Rags Gardner and Simon Tindeman seem to be the main three. http://21stcenturyshoebox.com/tools/ACRcalibrator.html The Tindeman script reads all the patches and allows you to "Weight" the importance of each patch. The skin tone patches are more important to me than the RGB. I got similar numbers to you using the Fors script.
Now, if only we could get Lightroom to automatically correct CA, we have a great wedding converter. NX does a brilliant job at CA correction. I tried to work out a way that NX could correct for CA, then into Lightroom for the rest.
I created two user presets (one for D3 and one for D200) via Camera RAW i.e. open one RAW file from Adobe Bridge and before loading it to CS3 setting up at the Preset (far right at the top next to Camera Calibration). Now I can right click any new photos (one or in group) and choose Development Setting and then click either the D3 or D200 presets. And I can do it either at Adobe Bridge or Lightroom 1.4.1 or the new 2.0 Beta.
I followed this thread, have setup the Hue and Sat per some of the suggestions to see what I think, gave it a preset name, etc. I'm not finding "Development Setting" that was mentioned and I could also use some help in understanding how to do a group of pictures versus just one at a time in ACR. Thx.
1) Develop Settings (I'm using Windows Version): a) Adobe Bridge - (i) select a photo; (ii) right click the photo and you can find it between "Batch Rename..." and "Lock Item" b) Lightroom - same procedures as above and you can find it between "Create Virtual Copy" and "Metadata Preset". Alternatively, go to "Develop" Page and it on the left hand inside the "Preset" folder and under the Lightroom Presets.
2) To open more than one photos (Windows user) select the first one and then shift click another or choose select all. Then right click to open "Develop Setting" and click on, in my case, "D3" preset.
I tried to keep up with camera calibration with ARC/Lightroom and in the end gave up. Too many different lighting/white balance situations to make it practical imho. I find it easier to just eyeball the colors and adjust as needed. I do find it interesting that the scripts you guys are running are showing the reds are still significantly off with a D3. I knew they were off shooting with the D200 and almost always had to tweak them but to my eye the D3 isn't off by much....what I also found is using CNX to make a pic of the same color chart used to calibrate ARC the color values are completely different. And that is using the camera the way Nikon intends it to capture color...hence my decision to just let go of trying to make the camera/software make colors like the charts.
The Nikon NX colours are "nice" but not very accurate. For most uses, they are fine but for labels on products or anything that needs accurate, I find it worth doing a Gretag shot.
I've been playing with NX a lot in the last few days (Easter Holidays) and am disappointed with the skintones and the way the tones dive for shadows (almost a step rather than a gradual transition). For non people shots the D3 produces lovely punchy images. NX seems to compress down the highlights, for example, a shot with clouds in will show better details in the clouds than the same shot opened in Lightroom. Almost like a multiply layer is being applied to the highlights.
Does anyone know a way to get the CAC (automatic aberration correction)of NX as part of a Lightroom workflow? I'm happy letting the software chunter away for a few hours if necessary. I like the CAC and control points in NX, it's just the rest. sigh..
I'm a bit new to this, but for studio settings (lights at 5500K), would any of these calibrations apply?
Also, I'm just not seeing where to do this in LR. I go to Develop, to Camera Calibration, and it only shows the default ACRs. I can then change these, I know, but I had read somewhere there was also a "Camera Neutral" calibration profile too? And if I save the preset, the Camera Calibration still shows ACR 4.4.
In order to create a calibration for your camera, you need to photograph the card mentioned above, load it in to LR and run a script which will churn out results that you enter in LR and then save. I've only done it for PS so I'm not positive it will work in LR. Try looking at this site.
