I am migrating most of my sharing from previous blogspot to here …. at the same time also update some of my update …… for how I shoot MACRO, I didn;t change much except lighting, diffuser (which I do keep improving it …..) and time spent on MACRO had been reduce @2010. Hope I can spend more time to MACRO 2011 ….

1. Manual Focus

– this not been change I use manual focus for my MACRO and Landscape shooting … may be that’s why my 5dm2 still serve me well …….
– due to the swallow DOF so it is not easy to get the AF work correctly what you going to focus especially at >1 life times
– so I will fix my magnification, then move myself backward & frontward to get object focus instead of turning the focus ring (do not do this for start) …

2. setting

2.1 ISO

– lowest possible but depend on whether how efficient is yours’ diffuser… if you make one lost too much light and you may need to push higher ISO but this have to be control together with aperture … normally I will suggest reduce one stop from ISO then follow by aperture instead only pushing ISO straight

– this may also depend you want to control yours’ BG or not … more old discussion – How I control Background …. to bring more BG color, we may need to push higher ISO ….

2.2 F number or aperture

– refer to how is Aperture affect MACRO Here

– so minimum F number I use will be
<1:1    F5.6 – F16      —> F8
1:1      F11 – F16      —> F16
2:1      F11 – F14      —> F14
3:1      F8 – F13       —> F11
4:1      F5.6 – F8      —> F8
5:1      F5.6 – F8      —> F7.1 –

I provide the recommended aperture range and F number I use 😀
– you may ask
i. why I reduce the aperture/F number and this eventually reduce my DOF
– yes, it will reduce DOF but i have to maintain the sharpness which impact by Diffraction (higher F number use will make picture softer)

ii. why my pictures DOF look thicker and ~same with 1-4 :1 even smaller aperture/F number use ….
– I focus stack my pictures so DOF in my picture is result of multiple shooting with stacking. what is focus stack ? please refer here

2.3 Shutter speed

– for full flash MACRO, I try to use flash MAX sync speed normally it should be ~1/200-1/250
– for Natural Light/Fill Flash MACRO, use aperture mode and let the body decide for you .. so mostly it may require tripod for slower shutter speed to avoid shake
– for start I will prefer to have minimum 1/125 or above
– what I use –> 1/200… 5d MAX sync speed

3. Flash, Yes or No???
– if we use flash, it will depend full flash or fill flash
– full flash will give flash compesate all the light requirement but fill flash is like Natural/available light macro where most of the light should be ambient light but flash just to try to light up, reduce shadow …..
– this is very subjective question where it depend environment, bug, light condition .. etc ….
– normally while shoot Natural Light (NL) without flash, I will use Aperture priority mode…. F8 then will adjust ISO to get correct aperture

– what I use –> 90% full flash
– while use flash, the flash have to be diffuse. why .. may be I should share more on this .. but simple share 2 pictures below to share different diffuser result …

different with different diffuser

– I will share another topics regard diffuser very soon …

4. diffuse or not ?

– this is most important portion (for me)
– if you din’t get diffuse correct, object details will be loss even you got it focus

my new lighting for both

long focal length full flash macro lighting – SIGMA150mm

shorter focal length full flash macro lighting – Canon MP-E65

*** sorry for most the link still old one.. and I am trying my best to update those link  and migrate over here

5. flash exposure compensation (FEC)
– it is important to control the light require…
– most of the time we need find a standard value for our setting .. for both of my setup I use -1 FEC as dafault
– what/when I change ? I normally plus FEC while I have brighter BG or I need more BG color to be light up…. then if the BG have black or dark BG then I will reduce the FEC ….

ok …. let’s go out and shoot now ….
