Is there a way to create a gradient map effect in illustrator? I tried different bledning modes but I cant get it to look the the photoshop version. Thanks in advance for the help.
Not by default no. There might be some plugins to do this.
However it wouldnt really work eactly the same way as in a raster image, since vectors dont work exactly the same. I think we have a question on why a curves adjustment doesnt really seem to produce the same thing in vectors as in raster graphics somewhere.
