I created some tiff files with transparent edges in Photoshop. Then I placed them in InDesign CS4. Then. I put some colored shape behind the Tiff Images. However, the placed link edges look white instead of transparent. What should I do in order to work with half transparent images placed inside the InDesign. Do I have to convert them to "psd" files if the TIFF doesn't work that way?
Transparency won't work when transferred to InDesign, that transparency is only for within photoshop.
You're better off using an opaque image in photoshop, import that to indesign, and use the Effects panel to apply a basic feather to all edges, or you can apply a gradient feather to individual edges.
When you save as TIFF in Photoshop you must choose to maintain that transparency. Open the TIFF again and choose save as...that will bring up the TIFF options dialog.
Thanks. Bob's answer solved my problem.
