I am deleting backgrounds using eraser > saving > then combining these images into a collage on a new blank document. When I file place the tif's are SO BLURRY. I always do my work like this, but just updated my PS. File, Place is now File, Place Embedded or Place Linked. Let me know if y'all have any fixes.
Do the TIFFs look blurry when first placed? (e.g., When first inserted *before* confirmed? Or is after confirmation?)
OK you noted the image files are high quality photos what can you tell us about the document they are being placed into? What is your Photoshop preference for default interpolation set to.?
