Is it cheating if I turn the monitor saturation up?  Is it OK to calibrate to 200 cdm2's?

doesn't really matter. one either has good color vision or don't but that doesn't mean he can't be a visual person (for example in case of Ansel Adams.)

I aced that test a couple years ago, but now I'm a little afraid of diminishing returns, so I'll pass.  But congrats on your perfect score.

There may some irony there in that if our media and printers had eyes, most of them would fail that test miserably.

You're right of course, you've either got pretty good color vision or you don't.  When I started with Ektaprint Type C's in 70's I asked an ophthalmologist to check my color vision.  He pulled out a couple small charts and after about 15 seconds said, "yer good to go!"

My take is the test is irrelevant. What you do want to say in your art is far more important than any technical aspects used to create the art in the first place. The test itself is another example of the industry's marketing efforts to market the things that we don't need.

Kind of fun. I scored a 7 without agonising too much. Of course it has very little bearing on your photographic ability, even for technical stuff.

this test is not designed for photographers; but, it's more appropriate for visual professionals or so-called visual artists since technically photographers are considered technicians or camera operators.

I did the test a couple of times over a year or so and scores were pretty good on one I did very quickly.  On the other, I did less well even though I worked more slowly and labored over some decisions.

Now, I wonder if there is another factor that interferes when you labor over such a test:  on a large (30") and accurate monitor, as you stare at part of the color bars, do your eyes adapt to the colors so as to make your view of the bars on the other side of the screen shift?  I don't see how it is possible for that not to happen, but again, my little bit of knowledge might be a dangerous thing  :)

I tried this test a while back, struggled with it for maybe twenty minutes or so, and scored something in the mid 200s I think. So I learned that I have defective color vision, which I have known for fifty years.

The very simple and straight-forward Ishihara color tests can tell you that in an instant (typically, a field of colored spots is shown, and a person with normal color vision sees a letter, while one with defective color vision may see a number or a different letter.

I scored 11 with an 80cd/m2 display.

I'm satisfied, yet it doesn't mean that much art-wise.

Same with me. I think my best score was in the 60's.  I guess us 'color defectives' just see things a bit differently.  I know from comparison with others that when doing things like game spotting, I tend to look for patterns rather than color.  This must be reflected in my (and certainly Eric's) photography.

Hi Chuck,
You understand, of course, that you and I see everything properly. It's the rest of the world that's got screwed up vision.   ;D

Well, there is people that asserts that part of Vincent Van Gogh success was due to being color blind...

Oh yes, I agree.  But I haven't had much luck convincing others of that viewpoint.  :)

Well, if it's just you, me, and Vincent v. G., that's good enough.

but he was considered a failed artist in his days, so was Paul Cezanne. If you apply today's definition of success, which is measured how much bank credit one can obtain, both must be categorized as colossal failures. Of course, the art world will tell you otherwise because their work can command hundreds of millions dollars in the art marketplace today.

I scored 3 without too much trouble.  But I never considered myself particularly sensitive to colour anyway - my wife is streets ahead, but then I might get her to take this test too!  I love tests though, and annoyed now that I'm imperfect!

You must be the first married man I meet who didn't know he was not perfect...
