Drop shadow affects vectors inside placed image in InDesign CC
I am currently adding drop shadows to placed pdf images of vectors in a new InDesign document. I just want a simple drop shadow around the bounding box of each image. For some images that were originally vectors created in Illustrator and then turned into a pdf before placed in InDesign this works as expected and desired. For other images when I apply a drop shadow, it applies to the bounding box, as well as all text and vectors inside the actual pdf image, so everything has a drop shadow rather than just the bounding box.
I am guessing it has something to do with the way I exported the pdfs. The one difference I've noted is the images I don't have a problem with were made and exported directly from Illustrator. The images I'm having problems with, have vectors in them, but the final design was laid out and exported from InDesign.
I have tried exporting the images as different file formats, different color conversions/destinations. If I try using a .tiff, jpeg, or png, rather than a drop shadow on every item inside the image, it changes the colors of the image if I try applying a drop shadow.
The only thing that made it stop was if I changed the document's transparency blend space to RGB, but that then changes the look of the rest of my images.
Any help would be greatly appreciated!
