>>3047299Really, really hard to get good colors underwater if you don't use a flash. I'd recommend just shooting black and white if you go flashless. Pick up some Tri-X and have fun.
For film:
I wouldn't shoot Provia since it already tends to go blue...the last thing you want underwater.
That ADOX is going to be useless at 20iso.
Great grab for $50! Mounting the lenses upsidedown makes adjusting focus easier btw.
