Change of colour when I use Drop Shadow

[Maureen5EE8]

Hi all,

I have an image in the background of my page and place a text object above.

When I use drop shadow on the text object, it changes the colours of my image underneath.

What can I do to apply my effect without altering my image's colours?

Can you please supply a sample image? 

Bottom line is that adding a drop shadow is using a transparency. 

If you use Edit>Transparency Blend Space and check if it's CMYK or RGB.

If the image beneath is changing colour, it's because the standard drop shadow effect is set to Multiply (you can edit this in the Window>Effects Panel and double click the Drop Shadow to edit it's appearance)

The drop shadow colour is usually black at 75%, set to multiply (from memory.. I'm probably wrong on that).

Hopefully that gives you enough to go on.

If the image is changing drastically in colour - that's another problem.
