G7X II Red Filter???

[kradatzke]

With it being so close to Christmas I decided to give myself an early present , went out and bought the Canon G7X Mark II with a Fantasea housing. I bought the Fantasea red filter at the same time, it is the one with the rectangular filter in a large round holder that snaps on the housing. I am not overly excited about the bulkiness of it and since getting the housing realize it has a 67mm thread that I can use a screw on filter. So a few questions on switching to a screw on filter

Is Mangrove Red filter a good brand? Will the screw on filter trap air between the housing & filter ? To me a nice compact screw on filter makes way more sense

I have not used it underwater yet but I read ( in the manual) that the Canon G7X Mark II has an underwater mode. The wording in the manual is " This mode can correct white balance and match the effect of using a commercially available color-compensating filter" Switching to this mode seems to turn the image in the viewfinder a shade of red but really to me looks more orange. So my question is do I even need a red filter ? ( going to Cozumel in Jan) Does the underwater mode work as good as using a filter

Has anyone used the G7X II without a red filter ? Did the underwater mode do the trick to get reds back in the pictures ?

Mostly stills , although I'll be doing the Bull Shark dive in Playa and will want to get some stills and video of that dive

The red filter -- any red filter -- will only correct properly for one kind of water (greenish,. bluish, coastal, open, etc) at one depth. so, most of the time you need to do post-processing anyway. If you use a light -- video or strobe -- you do not want a red filter. So, forget the red filter and just do post-processing. Shoot in RAW to make this work as well as possible. Go ahead and use the built-in white-balance correction, it will help with your JPGs, but provides no value for the RAWs.
Color Filters vs. Post-Processing
One big disadvantage of a red filter is in low light; all you are really doing is cutting down the amount of light that hits your sensor. The red light is already minimal; with the red filter you are also cutting down the other colors. So you are making a bad situation worse.
