No
how do you correct for colour casts that you cant see? i usually rely on the camera to set the wb and leave well alone but some of my shots have a tint (so others tell me). anyone help?
 
Looking at some of the posts on here I'd say 70% of them are........... no offence..........tee hee.

like your avatar...looks like my brother sid..

if you cant see the cast and others can...you may need to have someone audit your pp...before printing
 
I went through my life thinking I was slightly red green colour blind However a recent test showed I was 100% ok.
When I tried to be a cadet in the merchant navy I failed the colour test ... Red and green sailing lights at 3 miles. My problem it seems was that I could not define the light at all. ( I needed glasses)
 
I am a little bit.
Sometimes see yellow as green, red as purple but only when they are very close to the other colour.
 
I am also slightly colour blind. It must be really slight though because never had a problem with PP - well not regarding casts at least.
Colour codes on resistors with that light blue body caused me some grief; was it a red or brown stripe? Redundancy solved that issue :)
 
Yep I'm seriously red/green colour blind and its a real pain. I posted a black and white film shot last week which apparently had a pink tinge. I couldn't see it but when I converted it to black and white (again) it was definitely different.

Beat me to it!
 
[QUOTEIn that last test on the page you link to, I see a 2 and a 5. What does that mean? ][/QUOTE]

colour blind in one eye?
 
Dont get confused with that link, it is not a colour blindness test but a colour perception test which is totally different.
Colour blindness tests are judged using wire tests, lantern tests etc. Theres about 5 tests in total.

but it is the only one everyone uses for 'colour blindness' tests in the nhs etc

fwiw I am supposedly red/green colour blind but can do at least half those tests and have passed the lantern test - and more importantly for me can distinguish between red and green nav lights when I'm sailing

as for the other comments about how it affects your PP skills I find the best thing to do is to go away and come back a couple of days later.

When I do that I see a huge difference in my perception between what I thought was ok and what I think when I come back refreshed
 
A few real answers for you...

1 - work in B&W!

2 - learn to colour correct by using a McBeth chart. Photograph a McBeth at the start of the shoot - then if you change location etc - do it again. For a studio session you could shoot the card - or a grey card at the beginning of each lighting change.

Simple read the values of the square - and then change to get them to where they should be. At it's simplist, the 18% patch should have value of 119 - the black of 40 and the white at 235 (as you will get things brighter than the white square, and blacker than the black square. All the 3 channels - red, green and blue should be the same. If you do that you have the colour balance, contrast and exposure correct!

So I guess it doesn't matter then ;)

nb I'm a graphic designer and slightly colour blind. I can't draw either. I was asked to retouch out a brown leaf from an area of foliage - and could not for the life of me find it - but then asked a friend! That's what friends are for.

thanks David, a practical solution to my problem :thumbs:
 
A mate of mine is pretty much totally colourblind... But is an awesome photographer!!

And in my AS class he has the best pictures for rich beautiful colours... I find it really strange. And hardly ever shoots in black + White!!
