Hi, I shoot with a Canon 70D using a Canon 100mm Macro (non-L) Lens. I've read about using a yellow filter to achieve fluorescence shots of corals and am looking to purchase one to try out.

I came across the following 2 yellow filters on Amazon and am not sure which would be more suited for taking such fluorescence shots. What I do notice is one of the filters is described to be for a "mild" increase in contrast while the other is for a "noticeable" increase in contrast. Would the "noticeable" one be better?

Could anyone advise me please?

i haven't used these for any kind of quality camera yet, but here are the two things i purchased:

http://www.amazon.com/Ikelite-Yellow-Barrier-Filter-Dive/dp/B00QLI69YG?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_search_detailpage

the large sheet of yellow gel actually works really well. i was surprised. i'm seeing nearly equal detail to the ikelite mask filter i got.

from what i've seen with my eyes, it looks like the sweet spot is right around 15:

please excuse the potato quality, as these were shot with a cell phone, but here is the ikelite with partial coverage for contrast:

and here is a side by side for the gel filter plastic:

sometimes, if you're quick enough, you can even catch the fish fluorescing ;)

Do yourself a favor and first find out which one works for your lights first. Most people here will tell you not to use filters and just do post processing, but I'm not one of them. I love using filters and saving time, but I digress.

Get one of the ones I use on eBay and once you find out the number that really works well with your lights, then order the full circle for your camera. That is what I did and I am super happy.

Check out my thread about this same subject.
