I had slow down a lot on macro for pass 6 months ….
my previous testing on my lighting …. is mainly for Canon MP-E65 or you may refer here and only once I test my SIGMA150 light HERE …
and now …. I am working on my new SIGMA 105 OS … as below .. just a start for how I bring my flash closer …. and making the diffuser in progress …….
and stay tune .. more testing result for 5dm2 + SIGMA150 and 7d + 50mm MACRO

update version
1. stronger arm that can handle heavy flash like 430EX , sb600 etc …
it is always good to bring flash closer to the object which help to freeze the object even wind or hand shake (for more info please google “Inverse-square law for Light”)
quick explanation : (we have some sample from http://www.rodandcone.com/2008/05/flash-durations-for-canon-580ex-ii-and.html)
1/128 power = 1/36313 seconds Flash Duration —- SCALED to REPORTED DATA
1/64 power = 1/25341 seconds
1/32 power = 1/19232 seconds
1/16 power = 1/12914 seconds
1/8 power = 1/9151 seconds
1/4 power = 1/6107 seconds
1/2 power = 1/4019 seconds
Full power = 1/833 seconds
Canon 580 EXii – Distance from Flash to Sensor: 2 feet
1/128 power = 1/52718 seconds Flash Duration —- SCALED to REPORTED DATA
1/64 power = 1/38845 seconds
1/32 power = 1/26887 seconds
1/16 power = 1/18626 seconds
1/8 power = 1/13039 seconds
1/4 power = 1/8447 seconds
1/2 power = 1/5006 seconds
Full power = 1/871 seconds
simple compare, the lower the power mean we have faster virtual shutter speed which help to freeze the moment (due to wind, hand shake and etc) … so if when we do handheld macrophotography, it is always good to make flash closer to the object …
so some of my testing are base using the flash bracket (which bring the light source closer to the object)
e.g.
with Wimberley bracket with samples pictures

cheaper version of twin arm bracket

some sample use this with SB400 flash from Michael Ee
this bracket is in-stock now …
RM180/each (with advice how to design the diffuser with yours’ current setup – lenses, flash…..)
contact me if you would like to own one or look for advice …..
my last update for my MACRO setup was Jul 2010 … which discuss @ http://liewwk-macro.blogspot.com/2010/07/how-i-shoot-macro-new-accessories-and.html
but since then I have put most of my time to landscape … not much thing change but just to share it to my new blog …
my update short focal length full flash setup
some result
some result as below
i. concave, V & Light tent
ii. UV & Light tent
my SIGMA150 with Kenko ET, Kenko 1.4TC still my natural light macro setup … while I am still trying to resolved the full flash concern .. my last update @ http://liewwk-macro.blogspot.com/2010/08/how-i-shoot-macro-lighting-result-for.html
some results
possible for MP-E65 and the Background color (F8, 1/160, ISO100)
ii. with only ET @full magnification
iii.plus 1.4TC
iv. full magnification front view
it look pretty acceptable to me but I still trying to improve it and I will mostly use SIGMA150 for coming weekend outing ….
think now the light tent diffuser started by Stephen is a very good solution for macro .. do not worry on what you have trying to find a good way to DIY your tent/cup diffuser, yours lighting will be almost ready …..
few sample of the simple tent diffuser user
sample result from kit len + raunox202 + lighting diffuser with build in flash …. visit Jeffrey Photostream
if you interested to know more and know how to DIY the lighting for your MACRO setup … you may attend one of my workshop or outing to ask further 😀
