    I have been reading the thread on 'Which digital SLR' and was intrigued by
    the discussion on skin tones. When I was a teenager I was much better at
    drawing than painting because I have slight colour vision problems (only
    slight not red-green or anything dramatic) and this was enough to put me off
    serious painting. Later, when I took up photography in my 20s I decided to
    stick with black and white in the darkroom and leave colour to the
    processing labs. Now that I use a digital SLR I use Photoshop Elements to
    change a lot of things but rarely change the colour because I don't have
    much confidence in this area. I have used the 'eyedropper' in the colour
    cast tool to change things that I think should be white but this doesn't
    allow for whites that have a colour cast for another reason. For instance,
    I took a photo of a cat with some white fur and changed this to white on the
    computer only to realise that the cat's fur should have had a peach colour
    cast because it was sitting on a peach sheet on which sunlight was
    reflecting. There are so many colour casts in an ordinary room that I have
    some trouble sorting these things out. It is impractical to shoot a colour
    chart for comparison in every situation although I'm sure that it would help
    in some. I am just looking for ideas of how to manage colour now it is much
    easier to manipulate than ever before.

    You are right. Many pictures contain colour acsts that are not due to the
    colour temperature of the light source

    Can you set a custom white balance with your camera? This may help you.

  3. I am red, green, blue colour blind (severe to the point where I can't see
    the text in some magazine adverts).
    Many years ago I used to work for a photographer and one of my jobs was
    converting
    negatives to positives by rephotographing them onto recording film via an
    upturned colour enlarger head (using the filters in it to get the colour
    balance right).
    That WAS a wonderful job!

    I use the auto levels in photoshop and a bit of unsharp mask and just hope
    for the best.
    Its all you can do really.

    It might be worth exploring Black and white.
    I get a lot of fun out of it and tend to leave the colour up to a lab to
    sort out if I need decent prints.

    This page has two images:

    Top one converted correctly, bottom one just doen with the desaturate
    command in photoshop.
    You can get some really nice results like this:

    reason)

  4. That's not a severe disability - that's a normal response to some fancy
    advertising (and too much editorial content). Whenever I ask for feedback on
    layout the top of the list is always "Don't put text in anything other than
    black and don't put text over pictures."
