Re: Multiple flash units at 1/128 power

Hi Adi
As mentioned, there are no problems if you use the same flash units.
Problems can occur if you also use a different model!

Multiple flash units at 1/128 power

Hi I am reporting here about the "Yongnuo 560IV" and the "Yongnuo 560IV negative display". My observations and measurements are important for drop photography and to achieve a very short exposure time, i.e. to avoid blurring. Regarding burn-off time and Shutter release delay of the flash units, ther...

Hi Macroro
I like that!
A very nice picture, technically flawless right into the corners, only very few artifacts.
A pleasure

Re: Scales - pushing the envelope (of my kit)

Hi Beatsy At high magnification and higher aperture, these scales hardly show any more detail. I suspect that the highly reflective scales on your image show a lot of artifacts and not details. Both images are overexposed and therefore any structures are not visible. I think these highly reflective ...

Re: Charaxes lucretius

Hi Macroro
Wow, really excellent!
The Nikon BD Plan Apo 40/0.80 at 40X on a crop camera (factor 1.5) takes extremely good pictures!
Object-side image width high and high resolution,
what more could you want?

Re: Papilio ulysses scales

Hallo Macroro Deine Schuppen sind schön und sehr gut! Erderschütterungen sind tausende von Tonnen die sich leicht aber kraftvoll bewegen. Die kann man, auch mit 100 kg nicht beruhigen. Dein schweres Fotosetup bewegt sich fast zu 100 % gleich stark wie der Boden im Keller. Was man machen kann ist, da...
