I photographed for Olan Mills for a while - I know cheesy but I was
into doing intereesting poses and compositions - some ideas:

- saw another guy do this - when she's sleeping - prop her in the right
position - a little sitting up - need lots of the same colored soft
pillow - try white - then cover with a pink blanket - make sure a dood
portion of the face is showing - now the tricky part - move her hand so
that's just touching the far cheek or lips while also resting on the
pillow - get your wife in there - she'll know when it's a totally
"cute" shot - then take the shot - also, try pink gelatin paper over
the flash - it will wash pink over the scene

- butt shot - no nudes but the classic diaperless shot while she's on
the floor on the rug - get that tripod down low - don't shoot down

- also, you can sometimes get grreat hand poses even if awake - propped
up again by pillows maybe - small pillow or something in front - keep
going up and grabbing both hands and pulling them together in front of
her with a pose that looks good - let go of the hands making all sorts
of goggley-woogley noises and stand up and back out of the image -
you'll need someone else to fire the shutter or have a real long
shuttter release in you hand - may have to do it over and over 'cause
the hands will most likely keep pulling apart - but oon the 20th try
they will stay there long enough to get the shot - and by making noises
and backing sideways out of the shot her focus will remain on you and
will be looking out of the frame instead of the ever common look
straight at the camera pose
