Edmond, I am loving your DIY projects. Great stuff!
Personally I am looking at a pair of Keldan Luna 4 lights to use with a GH4. They seem more appropriate than the Luna 8 for principally macro work. But I'm very intrigued by a long-reach small light that I can use to get behind subjects for real 3-point lighting, and it looks like you've found a nice small light for that. Can you really get it behind the subject while it's still mounted on the camera or do you detach it?
I use a loc line attached with the light to work as a "leg" !! By adjusting the loc line you can "seat" on most surface, or wrap the loc line around anything unharmed. Also, the fibre optics is about 30-40 degree curved at the end, it can very easy to get behind anything, and shining from the bottom upward !!!
I don't mount it with the housing, it give me so much freedom to creat a very different light source.
Different people use different ways to achieve what they want. To my concern, what is good ,what is bad, it doesn't matter. What matters to me is the process to find my own resolution while I face problem and if I can get what I want at the end.
Your comments are loud and clear regarding using different system on supporting underwater camera. And I thank you your input to my topic.
I would also like to said that my topic is BMPCC filming setting. I post my pictures is in respond to a gentleman asking a more detail regarding the platform I made to support BMPCC housing.
Please accept my apology that I open this topic is to discuss the issue relating to BMPCC housing. Other than that, you are welcome to open your topic.
This is not my first time to use this kind of setup. I have been using this setup to shoot underwater video for 4 years.
I know very well how good it is, to use 4 legs better than 3 legs, and a longer legs than short legs.
To my understanding, more legs, more stable. Most of the chairs we are seating have 4 legs. The dentist chair that I am seating everyday to treat my patient have 5 legs. It just more legs you have to adjust to find the balance, but once you balance it, it is more stable.
To give you some idea how good it works, you can take a look at my video below.Those magnified shoot on Harlequin Shrimp (2:50)can be so stable by using 4 legs platform to film, and so as all the other shoot.
