Red Filter For Olympus Housing Pt-037

[Dr Wade]

I'm looking for a red filter to fit an Olympus camera housing (PT-037). The part number for the red filter is M67. This is all for the Olympus camera SP-560UZ. Olympus does not support this camera or housing now.
I am new to underwater photography. In fact I just got back from Kona and took my first underwater photos with the above setup. I think I did okay, but Really could use a red filter.
Any Ideas where I might find the Filter?

I think M67 is type of connection on your housing, ie. 67mm thread. You can purchase M67 red filter easily from many on-line store. Some popular manufacturer is URPRO, Magic Filter, Dyron ect.
However, in my opinion you don't really need red filter. Your camera capable to shoot in raw where you can post process to restore the colour.
Red filter does not add red colour - in fact, it will reduce exposure.0.5 stop.
