General / Nice results using a ring flash!

Hi all!
I just wanted to share a tip that might come in useful to some of you. I've been working a lot with close range photogrammetry in low light situations, and have grown tired of rigging lights and hauling that tripod around. I even used handheld lights to paint light into the shadows during long exposures - which worked nicely as long as the fundament was sturdy enough to cope with the movement. I bought a Godox AR400 ring flash. It has a built in battery and quite powerful led light for focusing. It enables me to shoot at iso100, f8, 1/200th sec, with my 20mm fx setup, and still get fairly decent exposures at 20 feet distance. The result I get with this setup is by far good enough for my use, - it also makes the shooting process very quick compared to using a tripod. You can find some examples of using the ringflash in my sketchfab gallery: https://sketchfab.com/gunnar/models
