I like to take macro (micro) shots. And for this reason I need a light. It is because I want ti use ISO 100. And I need greater possible DOF. And therefore F should be 16.... til 32. At normal sunny day photo is black. If you Have not artificial light.
Answer is a flash. Strong light. Fast light. To freeze movements. It shall be perfect!
So, I need to buy a flash.
Normal flashgun - illuminate from front and pictures are flat.
Ring Flash - "dedicated" for macro - the same story - pictures without deep.
Well, we need a light source from side and litlle above... about 45 degree.
Twin flash! Main from left and right to fill in...It has to be perfect!
I search web ... after days and tears, I conclude that I have not - I will not be a Jack ass for 500 ... 800 ...1000 USD.
So I turn to proven DIY.
Two smallest flashes from China.. about 24 USD.
Two optical hot shoe from China... about 14 USD.
A small Flashgun from E-bay... 25 USD... suited for ma A350.
Plate of Plexiglas 4mm and few hours in my corner. A lens hood ...
All hand made in several hours.
Pictures worth a 1000 words. Specially the last two.
You always have a choice.. to choose "dedicated" "only for me" "special" ...Jack ass for 000 USD.
