Invert Image In Designer?

[darita]

So I have a B/W image in AD.  How do I invert the image?  I know how to do it in AP,  but can't find it in AD.

Hi,

You can do this with an adjustement layer (screenshot in French, but it should be "invert" or similar).

Select the image and then go to Layer > New Adjustment > Invert.

Edit to add: or you can do as @Wosven just said.

Haha, we answered it at the same time

Another way is to cover the design with a black rectangle and set the new layer’s blend mode to ‘Contrast Negate’.

Strange

I get a different result when I try that

But if I use a white rectangle with a blend mode of Difference, Exclusion or Negation, that appears to work

So do I. Whether the covering rectangle is black or white makes no difference if the blend mode is ‘Contrast Negate’ -- either way, the result is a stark, pure black & pure white image with no greys at all. What exactly ‘Contrast Negate’ does is a bit of a mystery to me, but in this post @James Ritson says:

• Contrast Negate I'm not sure exactly, but it seems to invert the pixel values of the composite layer based on the image layer's content. Useful for certain designs. I've attached a really rough example to this post.

Upon further investigation, ‘Contrast Negate’ with a white rectangle makes grey or white text turn black, whereas red or black text turns white and disappears from view. I change the blend mode to ‘Difference’, ‘Exclusion’ or ‘Negation’, white text still turns black and black text still disappears, but grey or red text is inverted (so mid-grey looks unchanged but red becomes cyan).

With a black rectangle, ‘Contrast Negate’ makes black or red text turn white, whereas grey or white text disappears. The other three blend modes don’t seem to affect the appearance of any of the text (apart from keeping the black text hidden, of course).

With a red rectangle, ‘Contrast Negate’ makes black or red text turn cyan, whereas white or grey text disappears. The other three blend modes make red text turn black, with black text disappearing, white text turning cyan and mid-grey remaining unchanged.

With a mid-grey rectangle, ‘Contrast Negate’ and ‘Exclusion’ make all the text disappear. ‘Difference’ makes mid-grey turn black, but text in the other colours disappears apart from a few antialiased bits; ‘Negation’ yields a similar result, except that mid-grey becomes white.

How much red text is there in a B/W (greyscale) document?

Not much!

I forgot to re-read the OP.
