<...This does not sound like a random "controlled" study. ...> A "controlled" study means that there is a control or comparison group. Lisa Amir MBBS, MMed, IBCLC in Melbourne, Australia PS the digital camera I'm using is a Kodak DC4800 Zoom Digital Camera - I find it's pretty good, but I have trouble focussing at 6X enlargement if the light is not good. I'm taking photos at the bedside or wherever - and can't set up lights. I am no expert with cameras, so this is not an endorsement or criticism of this camera. *********************************************** The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(TM) mailer for lightning fast mail delivery.
