Hi all, My name’s Geoff Ward, last time I took any real Underwater Pics was back in 2005 @ Tavueni in Fiji, looking at going to Raja Ampat in October this year and trying to decide whether to switch from slide (which nobody uses these days) to digital, which will require buying an entire new rig, and adapting to it before October. I used to use Velvia 50 ISO very comfortable with it and loved the results, also very comfortable with my Nikon F90 in a Subal Housing, SB25 in a Subal Housing. Also used Fuji Provia and Kodachrome 100/200 ISO. I can discuss more if interested. Kind Regards Geoff Ward.
