Does it really matter wether it has 72 dpi or 5000 ? What counts is the amount of pixels you render in Vue. On what area they are spread out you can easily define in Photoshop - especially when you go there with your image anyway.

So what counts is that you have a method to bring your images from Vue to Photoshop in a format you are happy with. Tif or Bmp is not really important.
