Targa only supports 8bit images, so what's happening is your depth, 
which is likely greater than 1, is being clipped to the 0-1 range. So 
you get 0 for pixels where no objects are, and your clipped depth (1) 
for your objects - which looks like an alpha matte.

Try TIFF instead - it supports 32 bit floating point images, and should 
store your Z maps with ease.
