ColorChecker Digital SG Software for Mac?
« on: April 18, 2019, 10:15:58 am »

Hi, I think I just made a huge mistake of buying the ColorChecker Digital SG chart in order to improve my camera calibration for Adobe Camera Raw. I've been using Color Checker Passport with not so good results and was thinking of improving with this upgrade now to find the software for Mac is no longer support.
Do you guys have any ideas, any other software that would run in MAC and would create a profile for Adobe Camera Raw?
Thanks!

Lumariver Profile Designer I think may be a good choice for you but you may need to purchase the Repo version to allow the use of the SG target?

Check the manual for info if SG Checker supported

Surprised to hear that you are getting not so good results with Color Checker Passport, have you tried the Adobe DNG Profile editor a pretty capable FOC application.  Not sure if it is compatible with the SG Checker though.

You may wish to have a look at BasICColor Input 5.

My first question would be why you're not getting good results with the Passport in at least Adobe products. Sure, you can spend more money on other software and targets but seems at this point like throwing out the baby with the bath water. I've never built a custom DCP profile for the few cameras I have, using the Passport that didn't improve the rendering compared to a canned profile. Why you were not successful would be an interesting route to examine should you wish to go down that path first.

ColorChecker Digital SG chart in order to improve my camera calibration

a regular question - are you sure you can shoot a semi-gloss target (or even a sufficiently matter Passport/CC24) in a proper manner in the first place ? that is before you start using any software to make profiles

Hola Antonio,

X-Rite has released the Colorchecker camera calibration software 2.0 for PC & Mac that works with the digital SG chart

Well, first of all, thank you all for your time.

As Francisco suggested I'm downloading the new Passport software.

It's good to explain my shooting target procedure:

-Place the target on top of a black surface to avoid color contamination.
-use a flashgun with a small diffuser on a stand at 45 degrees from the target.
-shoot straight ahead.
-process the raw file in camera raw with Adobe standard profile and not corrections other than the white balance on the second gray patch from the left.
-save as DNG.
-Drop on Color Checker Software.

I'm attaching DNG screenshot and Color Checker Profile applied.

Good and bad news, I downloaded the color checker passport software but it only allows to create ICC profiles with the SG chart. The process is different, it won't accept DNG's only Tiff files and to create an ICC..

Hmm, here's what X-rite says in "Notes" -

Quote
ColorChecker Camera Calibration software ver 2.0 is fully compatible with the industry standard ColorChecker 24 patch classic target and the Digital ColorChecker SG target from X-Rite. You can use this software with ColorChecker Passport, ColorChecker Classic (standard and mini sizes) products and the Digital ColorChecker SG. The Software will allow you to produce Camera profiles for both the DNG and ICC color management workflows.
(emphasis above is mine)

I haven't tried yet myself, but are you sure it won't create DNG profiles?

Ach, two things:

1) XRite's sw is not considered to be the greatest profile generator (free alternative would be Adobe's own DNG Profile Editor, though I personally prefer the control of LumaRiver)
2) Are those crops or are they the actual image fed to XRite?  If the latter the tones could possibly be contaminated by gradients and vignetting.  I try to keep the target small compared to the field of view and in the center.

I also agree with others that for most generic photographic purposes the CC24 is not only easier to use but potentially actually better than the SG (for a number of practical and technical reasons).

Jack, this is a very interesting statement, insofar as it raises a more general technical question about how many colours of what characteristics are most satisfactory not only camera profiling but also for verifying the accuracy of a profile's performance. Industry practices are quite varied as I assume you know. I'd much appreciate if you could explain the "practical and technical reasons" you allude to just above.

There are .DCP (DNG) profiles and ICC profiles. Not remotely similar, not used with the same image data in the same processing path.
AFAIK, DCP profiles are only created using the 24 patch Macbeth target at least using X-rite and Adobe software. The SG (and DC) is for building ICC camera profiles.

Hi Mark and Andrew,

A DCP camera-referred profile can be based on virtually any target out there.  In fact software such as DcamProf/LumaRiver have reference values for most commercial ones built in, see the attachment.

The key word in my statement above is 'generic', as opposed to 'specific'.  Anders Torger and others could speak better than I about this (you know who you are, please feel free to chime in), I am not an expert, but:

From a practical perspective the SG is very finicky to set up and deal with, as DP alluded above, because its semigloss finish tends to create glare, let alone specular reflections, that can create havoc on the profile-creating math even when one is being careful. Some such software for instance has an option to ignore the more troublesome semigloss patches in the SG.  Anders quips 'Due to their difficulty during measurement the end result is often a worse profile than using a matte target.'

From a technical perspective, one has to keep in mind that 'accurate' dcp profiles are applied very early on in the long processing chain that leads to the final image.  No matter how many patches are used we are simply sampling the same gamut more or less frequently. The profile designer is presented with a trade-off: produce very accurate, tight fitting tones for the very specific setup that however may rip at the seams if the subject is significantly different (this of course might be quite appropriate in 'specific' applications); or produce a slightly looser fitting, though more robust, profile that will stand up better to the type of image and processing in a 'generic' photography situation.

It turns out that for generic photography the matte CC24 is harder to mess up and quite capable of creating such looser-fitting though more robust profiles.  So for most of us shooting the landscape without special needs a CC24 is actually a pretty good, convenient choice.

Hi Mark and Andrew,

Except Adobe's and perhaps (haven't tried the 2.0 software) X-rite.
EDIT: the 2.0 software makes it pretty clear that no, the SG isn't supported:

I completely agree Jack. The SG can make quite good profiles since it has a bunch more saturated patches well outside sRGB and even a few outside Adobe RGB. But if one isn't very careful with the way it's illuminated to absolutely minimize glare, even glare not visible, from the semi-gloss surface the profiles it makes can be pretty awful.

The original DC had very glossy patches and a wider gamut but was difficult to capture. The SG as the name implies, less so.
And of course, the profile gamut can't be any larger than the gamut of the target; just another restriction in ICC camera profiles.  ;)
