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!

This is a good point, the physics behind colour perception can be a bit interesting at times. We're not adding red, but removing blue to make the picture appear more "red".  Red filters appear red because there's no blue. Our view underwater looks blue because there's no red. :o Thanks for pointing this out.

Reminds me of an interesting piece I read a while back that demonstrates colours can sometimes behave in funny ways.  There is no such single colour called "magenta" - it is a made up colour caused by the absence of green (or the combination of red + blue). Mind boggling stuff.  ???

Very nice leh. What macro lens are you using?

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.

I am also using the extendable stick thing. How i wish there is a holder for a dive torch for this set up. Do not wish to buy the SP Gadgets light or the Knog light.

My setup was pretty crappy at that time.  Just a selfie stick with the camera attached and a video torchlight.

I am actually pretty new at macro videos with a gopro.  but i did a lot of research before my lembeh trip.
I use a backscatter macromate mini.  I think this lens does a decent job in getting a decent macro video.  I have tried some +10 china made ones and even polar pro +10 with poor results.  These turned out to be more like magnifying glasses instead of proper macro lenses.  I heard that some people have successfully managed to fit a camera macro lens on like a subsee or FIT with good results.

I recently bought another macromate mini and plan to double stack.  It will be a huge challenge to get the focus right.  Not sure when I will get to test it out.

Here is mine with Gopro 4 black. Just messing around when i was bored with shooting stills. Tried the macro mate in bali before this trip and didn't like the results. was using for most of the macro videos the FIT +10 macro lens. Even then you can see the magnification for macro on a gopro is pretty poor. Was hand holding the gopro and with the other hand an FIT 2400 lumens video light mostly set to low power.

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...

Nope.. I dun think the light guide works with the housing, it doesn't fit.
The pictures u see are taken <18m depth, that's the limit of the camera without the housing.

Good video.  I guess the main thing to take note is that a gopro is still a gopro.  Work hard at it and you may get some decent macro shots but you will never get great shots due to its limitations as it essentially a wide angle camera.

I think the TG-4 will do a much better job. Will give it a go my next trip.
