Why no red filter?
If you ONLY have a gopro to use for macro, use a macro lens like micromate mini.  Use video lights.  No red filter.
I do agree that the Mola-Molas are a MYTH!

Coz, macro stuff usually hang around less lit places.  Hence need a light.  U cant use a red filter + light at the same time.  Everything will just come out red.

In summary:

Wide videos: Just red filter.  Gopro at wide setting.
Macro videos: Macro lens+Lights. Gopro at narrow or medium setting.

Why no red filter?
Red filters are only required when shooting with sunlight at depth (> 5-10m). This is because the light loses its red spectrum (it is absorbed by the water) as it travels through all that water.

The deeper you go, the more red you need to compensate. Hence a filter that works well at 10m may still appear red at 5m, or blue at 18m.
If using a video light, strobes or other artificial light, there's no need for a red filter. Because the distance between the light source (torch), subject and camera all near enough, such that the amount of red "lost" in the water is negligible and not noticeable.

I took my Olympus TG3 out for testing last year.
You can check out some of the shots.

The TG3 doesn't do RAW, so post processing won't salvage really bad shots.
I purchased the Light Guide (ring flash attachment) for the TG3 as well, so close up shots colour reproduction is quite accurate, but further out, the white balance is sometimes a bit off. Suggest you get a small grey card or something for manual white balance.

You can see some of the close up shots, i think I got a few nudibranches.
Those blurred shots are a result of my buoyancy control.

Thanks everyone. so as to say, GoPro is mostly good for video shots and not good for those interesting wow,close-up shots. explains my doubts. Thanks Thanks. :)

actually red filters don't "add red".. they actually filter out the blue wavelengths, and the effect is that it will be less blue and it balances the filtering effect of the water which filters out the red wavelengths. due to this filtering effect of the red filter and loss of the blue wavelengths, less available light hits the sensors, so exposure is lower when you use filters compared to no filters. that's why some people complain their pictures are dark when they use red filters.

just like how coffee filters don't add coffee.. they filter out coffee!

I re-read the original questions.  Are you also thinking of taking pictures (not videos) underwater with your Gopro?  IMO, get a compact cam.  I honestly have never seen a good underwater photo taken with a gopro, wide angle or macro.  Hence to me it is a waste of time.  With a gopro, stick to videos me thinks.

by the way, if you want to see what a gopro+macrolens can do, check out my video at


Note that this was my first attempt at gopro macro hence it was not very good.  But i think that there is much more room for improvement.  I took those videos with a selfie stick in one hand and a video torch in the other hand.  Not exactly the best technique haha.  Next chance i get, i will try 2 video torches, a stable base and double stacking my macro lens.  Hope to get better results.

Sethy, does the light guide work within the underwater housing? I'm using the olympus housing and I thought I read somewhere that it is not compatible or something...

Hey!!! this is the sort of vidz or pix im trying to get. at least it more decent than my normal,red filter + GoPro.
im a bigineer so this is sufficent for me. :)

So to achive this kindda result, we need lights ey?? a single LED bulb is efficent or do we need a big ass,expensive dive strobe/light???

Can i see your setup for your GoPro in pix?? :)  At what depth is this???

The videos were taken at various depths.  9meters to about 25m i believe.  My setup was pretty crappy at that time.  Just a selfie stick with the camera attached and a video torchlight.  Both held by hand.  I used a Archon W17V  torch.  It is a small torch with no 'hot spot' in the middle.  About 600-700 lumens I think.  You will need a video light without the hot spot.  I think it is sufficient for macro.  Some of my videos lacked proper lighting because i accidently set my torchlight at medium or low when i wanted high beam.  User error.  Those huge and expensive 2000 lumen lights would be overkill i think but i am not sure. 

I dont have a pix of my old setup coz i i now use a different setup.
