Studio lighting comparison (flash vs. LED)
Since I use two different lighting system for high magnification studio photography, was curious about the difference of the effects.
Well, I chose a tiny leaf miner jewel beetle from my collection and did two stacking sequence. One lit with a Speedlite 580EXII flash through a plactic diffuser around the subject, and another with 2 IKEA table LED lamps through the same diffuser. Find the picture of the setup below!
Shots were taken with a Mitutoyo BD Plan 10x microscope objective on a Apo-Gerogon 9/150 enlarger lens at 9,2x magnification. 105 exposures in each stacks. Shutter speed with flash: 1/100 sec. (live view mode), with LEDs: 1/3 sec. (live view, silent shooting mode).
I found no remarkable difference in the light effects. Perhaps when the flashlight is coming frontwise of the beetle looks more natural than the two separated light reflection. Another strange thing appears: the different color of the LED lamps. I have 4 Jansjö lamps and none of them has the same colors.
Then I looked at the stacks at the original resolution and surprised of the difference. I do not know why, the LED lit version has slightly finer and perhaps sharper details. Check out the comparison below side-by-side!
