Stack-o-party !! ......+4,+4,+2

sulhan · 28th June 2003

Hi All...

Here are some photos taken todaytestin gout the 3 stack of close up filters... Last week i tried with a +4(55mm) , +4(58mm),+2(58mm). It caused some distortion due to the 55mm sized filter. The curvature at the edges mismatched the front element of the G2.

Got the 58mm +4 from MScolor yesterday and here are some test shots taken today at Alexandra Hospital Butterfly Trial.....

These ants seem to be going through a major migration. There were large solder ants securing the area(larger than normal ones)
Their claws are really large and a bite willl i'm sure cause some swelling!!!

CONCLUSION:
Using the +4,+4,+2 (all 58mm)stacked on a POWERSHOT G2 seem to give great images output. Choosing the right aperture is crucial to reduce color fringing at outer edges if the sun is bright. I would recommend an aperture of f5 as a rule of thumb. I found out after comparing framing with my SLR macro at 1:1...i realize the three stacked close up gives an equivalent framing size to 1:1 on a G2.

All shots were taken using the manual focus mode. Tripods were used in cases where shutter speed gets to loww...and when i am too tired!!!

TIPS:
As some shots are really chalenging due to shake(When handheld).....i would choose the "Multiple Exposure mode" making use of the 2.5frames persecond when i press the trigger....It will take 3 to 5shots and 1 will turn out sharpest......
Shutter Vibration problen is less in digital camera like G2 so its an advantage too...
