Colorchecker Passport Download !!EXCLUSIVE!!

thanks for any potential advice.
OBS: I verify the exposure before taking the color checker passport picture To avoid it, but I think the light was still strong and the camera measured from the black part of the passport case.

I would not expect to get any meaningful answers from Amazon about the actual age of the product, and I know X-Rite recommends a replacement of the passport, two years after the product is put into service.
Your passport to better Raw colour - by Philip Andrews, Better Photoshop Techniques
"The ColorChecker Passport is a sophisticated hardware/software solution that brings ease of use to what was a pretty complex task, namely, that of creating a custom profile for a camera's response to a specific lighting set up."
Additionally, the hinge is designed with detents to hold the passport in various positions. The panels lock open at 180, as well as in intermediate positions around 60. As a result, the ColorChecker Passport can be stood up on its own.
Over the last few years, I have regularly recommended the ColorChecker Passport. Colors are extremely important and the passport helps prevent issues that can come up with many digital camera sensors. Recently, I have been testing the Datacolor Spyderchekr and I wanted to see which of the two was the better option.
I have the colorchecker passport and need it as the main subjects I'm photographing are a Florist show flower namely Auriculas. With over 5,500 named varieties getting the colour as exact as possible helps avoid some of the arguments as to whether or not I've even photographed the right plant.
I leave the argument as to whether it was the right plant in the first place to the show judges.
The passport takes up less space on the show benches, where space can be at a premium, so it does the job for me.
I now have all of my screens calibrated with X-rite products. The are easy to use and are reliable. I remember back in the 90's using a control panel on my Mac to visually color balance my monitor. Technology marches on. One of the great features of the Colormunki is that it has an ambient light sensor that monitors lighting conditions and adjust your monitor accordingly. I carry a ColorChecker passport with me on all shoots so that when I get back I can profile my camera for best results. One of the best examples I have ever seen to justify the use of a monitor calibrator was when I was shooting official portraits for soldiers. On the uniforms soldiers wear awards that are various colors. When comparing a calibrated monitor verse an uncalibrated monitor the color of the awards would change. The red awards appeared pink. A calibrated monitor doesn't just remove a color cast, it renders individual colors properly.
I think you are not clicking on the gray patch with the white balance tool in the RAW converter to set the correct white balance. You still have to set the correct white balance when using the passport profile. The Passport profile does not correct white balance, it's makes the colors more accurate when the correct white balance is set.
Someone has sent me some "uncompressed" jpegs and each image has a colorchecker passport in the image. The images seem very bland to me, and I thought I could use colorchecker software to calculate and apply an appropriate profile to make the images more realistic. But so far I haven't been able to do this.
As I think you guessed, the dcp profiles in /Library/Application Support/Adobe/CameraRaw/CameraProfiles/ do not show up in the list of available profiles to assign to an image in Photoshop. You say "you'll need to make an ICC profile from the colorchecker." AFAICT, there is a tool at Sourceforge written in C++, without a Macintosh variant, that was last updated about 11 years ago, which I would have to try to compile to use. Do you know another way to convert a dcp profile into an icc profile? I don't even know what the difference is between these kinds of profiles is, but I suspect the fact that they have different file extensions means that they are not easily (or not intended to be) interchanged.
The CCP is a passport sized plastic case. Unlike the more traditional single sheet swatch, the CCP is both sturdy enough to be carried out in the field, and small enough to fit easily in a camera bag side pocket, or your own coat pocket. The CCP also comes with a lanyard (not shown), so you can even just hang it around your neck.
From what I hear from some friends who use the ColorChecker Passport is that they generally prefer the white balance 2 setting (two from bottom or left depending on how you have oriented your passport in the shot). For this shoot I chose 5 because I really liked the skin tone of the arms for this model.
Taking a look at the larger targets first, the average sampled white balance for the old passport was a temperature of 6865 and a tint of 1.3. The new color checker passport produced an average temperature of 7036 and a tint of 1.6. What do these results mean? It means that the old passport is measuring the light as 170 degrees cooler and 0.3 points more magenta than the new color checker. These difference show that the old passport has a neutral patch that is a bit warmer than the new one.
Moving on to the colored patches used to generate camera profiles for Adobe Camera RAW or Capture One I see similar but not identical results. The old passport is giving me an average white balance temperature of 7683 with a tint of 1.8. The new one gives a temperature of 7936 and a tint of 2.1.
The reason for the name is that this small colour chart is quite literally the size of a passport. That means that at 125 x 90 x 9mm and weighing in at 80g, it will quite happily slip into a trouser or kit bag pocket.
