Photoshop / displacement map unity of value

Question

Hello,

I'm looking for the unity of value used by the displacement map tool in photoshop

I'm using this tool to create anaglyphs 3D and then i need to print those anaglyph but not as a single sheet. I need to print blue and red separately to make an installation afterwards.

So in an anaglyph the blue and red sheets are not exactly aligned and i need to know by how much the displacement map has moved them appart.

Using the tool you choose a value, let say '10' here, but there's no indication as to what those 10 refer to: is it % ? pixels ? something else ?

You are of course right but 200% just means 256 pixels .....etc

Celine - if you want to check just make an image with a single pixel dot in the centre.

Apply the displacement map with a white map at 100% you will see the pixel move 128 to the left and 128 up. 200% does the same but moves by 256.............

Hi Celine - see here from Adobe:Apply specific filters in Photoshop It states the slider is a % value with the max displacement (at 100%) being 128 pixelsDave
