[QUOTE="Blue439, post: 823546, member: 53455"] A super-macro shot of a burlap fabric (the one I used for background in the World War I photo I uploaded to the Tabletop section a few days ago), using the Novoflex BALPRO T/S bellows [U]and[/U] two stacked extension tubes with a 50 mm lens. The reproduction ratio I estimate at 12:1. I thought I would never have enough power to light this without having to pose for minutes! I remember I had to use my two Indra500s at full power (that’s a whopping 1,000 watts/second! They say decent cobra flashes put out between 60 and 100 W/s), and quite close at that, in order to have enough light to reach the camera sensor, buried as it was at the end of the very long and dark tunnel of the tubes and the bellows, fully extended... I wouldn’t budge from my base ISO setting of 64 for a shot like that. ;) Composite shot made of 8 focus-stacked exposures, set manually using the Novoflex Castel XQ II focusing rail. Stack (very complex stack, with all those bits flying around!) processed with Helicon Focus. Nikkor Z 50mm f/1.8 S lens, Fotodiox Pro extension tubes (15 and 35 mm). Gitzo tripod, Arca-Swiss Cube C1 geared head. Artificial lighting. [ATTACH type="full"]409639[/ATTACH] [/QUOTE]
