Hello Pau,
Yes, it sounds logical.
“You want to use the flash at reduced power both to have less battery draining and shorter actual exposure time”
Yes, exactly. Many thanks!

Zoom position: 24mm or 105mm ?

Hello everybody, Does anybody know which zoom position is better for the flashing if the distance is very short and the subject extremely small? e.g. http://i1167.photobucket.com/albums/q623/marioleczka/Diffuser_frot_zpso6kna4r9.jpg Which position is more effective 24mm or 105mm ? Thank you in advan...

Hello Bushman,
In my case the biggest problem of the visual check are my eyes :-)

Hello Keith, hello Rik,
OK, up to yesterday I have ever checked the pictures in this way you mentioned
but yesterday I didn’t notice that one was improperly exposed :-)
Bye, Adi

Hello Frans,
“Something like that you do not find every day.”
Yes, that’s true. The background module doesn’t look like a self-made.
And the whole equipment is the finest one, which I only can dream of.

Hello Frans,
“My linear stage weighs 14 kg”
Awesome!

As far as I can see your linear stage allows the movements for very long distances.
Do you take photos from the large subjects?

BTW,
I’m looking for a linear-stage with a fine resolution (but a small one).

BR, Adi

check before stack ?

Hello everyone, Is there any tool for the checking of the quality of a set of photographs? I’m asking for that, because I had a problem with the stacking-software yesterday. One picture (of ca.100) was unexposed, because one flash didn’t fire. I didn’t’ realize that and started the stacking. So, the...

Set contrast threshold to?

Hello everyone,
How do you set the contrast threshold in Zerene ?
When should I change the default value 30 and what is the best practice?
Thank you in advance.

Hello Frans, “Yes, camera, linear stage, backlighting, foreground illumination and object holder stand together fixed on a single thick wood block 500x650x40 mm” But you have two metal-assemblies on the single thick wood block, which are not connected to each other by any metallic compound. I'm doin...

Hello Chris, “Frans makes amazingly wonderful things doesn't he?” Yes, he does ! “This way, if one of these vibrates, the other is likely to vibrate in concert with it” Yes, on the one hand you want to couple the camera with the subject in order to synchronize their relative movements but on the oth...

Hello Frans, Your wooden frame is great! I only have a low-cost wooden slat :-( Have you separated the metal-construction for the camera and for the subject in order to avoid the transfer of the mechanical vibrations? “I use the mirror-up function on the D7100 camera, wait 1.2 sec, I open the camera...

Hello Elf, “Use a bellows and change the bellows draw instead of moving the camera/lens or subject” This is really new for me. I have never heard about this method before. Many thanks! 3b: I have already asked for that http://www.photomacrography.net/forum/viewtopic.php?t=29415&highlight= BR, Adi

Hello Charles, Many thanks for the info! “electronic flash and EFSC generally cannot be used together” what a pity :-( I had a curious problem with the remote control of the flashes. As you already know I usually use the second curtain sync. But I wanted to block the mirror too. Unfortunately it was...
