To:
+ Optimum adjustment of the brightness of the screen (= less fatigue)
+ Color calibration which - from my side - proven: I was very satisfied with the color rendition in a book printed through a serious reputable site (and just for that, I give it 4 rating)
+ Ease of use to achieve these results
+ After reading a series of tests and review on the web, it is a probe that seems to come out on top in the category "best compromise" result - cost - convenience
Surprising:
~ It's incredibly light as material (like we can question what is in it!)
Suspicious:
- I have used on a single screen from the beginning (a pretty good screen): I do not know if the results would be as good on other screens?
- Calibration is available every month and it is very difficult to judge, but I already asked by 2 calibrations one after the other if they were exactly the same ... Anyway, I said leaves the benefit of the doubt, being very satisfied with the final result.
For the record ...
I do not know if this has happened to you but this is what I decided to take a probe: when I was touched - optimized a photograph on my computer, I displayed on the large screen of a friend. And then, surprise: the photo that I found so successful on my screen had a greenish tint very unpleasant!
In a photo, it is not serious. But if you are dealing with hundreds or thousands every year, it's a bit crazy to think that all the work we realize is our hostage settings screen ...
In short, a probe remains an indispensable tool (this one or another!).
