A little while back I mentioned that I was unhappy with some of the colours being produced by my GX1 and also LX5. The greens seemed a little too green and the image overall had a slightly blue cast to it. This inspired me to purchase a Color Checker Passport from X-rite as it could be used to produce a custom calibration for your camera which can then be used in the develop module of Lightroom. Well I have now purchased and used the passport and can report on its performance.
My first reaction when opening the packaging is that you don’t get a lot for your money. The passport itself is small and made from plastic. There is a CD containing the software which you load to your computer but there were no instructions other than a link to the X-rite site. In the end I watched a very good video of how to use the passport and software to generate a profile and all was clear.
The passport is basically a colour checking chart and grey card contained in a plastic cover. It’s small, light and fits neatly in your pocket. The first thing I used was the grey card in order to create a custom white balance for my GX1 (I won’t describe how to do this here as each camera is different). This was very simple and once the white balance setting was registered made an instant improvement to the images, removing the blue colour cast preventing the greens from looking quite so sickly.
Next I took two reference pictures of the colour chart in the passport. One was in direct sunlight and the other in shade, both taken around midday under a sunny sky. Back at home I converted the RAW files for the two images into DNG format using Lightroom and then loaded these to the passport software. A click of a button and 20 seconds later and my profile was ready.
Restarting Lightroom and switching to the Develop module I could see my new conversion profile which when selected had an immediate impact on the image. I noticed that the image contrast improved and some colours (red in particular) became much more vibrant and realistic. Colours also looked completely natural.
I wondered if this result had been a fluke so repeated the process with my LX5. The results were even better and the images now look very lifelike. The image here is of the edelweiss flower (I hope I spelled that correctly) which is actually quite rare and grows at altitude in the Alps. I found this particular flower at around 2,600m under a bright blue sky and took the picture on my LX5. The colours having used the “passport color checker” appear completely natural and subtle.
This tool is quickly becoming an indispensible accessory in my camera bag. I just need to remember to use it.
