Shes using a Sigma 50mm 1.4, Shooting at iso100, 1/125 and wants to shoot 4.0 to blur the background.. So.. No.. Cannot stop the lense down.
Hence needing to cut the light down.
Its possible to shoot under current conditions if your happy with fix it in photoshop, trying to get better straight out of camera to improve work flow for her.
Room is approx 3m x 3m.
Currently doing black background lowkey until white vinal backdrop arrives.
Plus will need the black background option for mum/bub <2wk shoots.
Using 2x300w @ 1/8th, key/fill. key is in 1.5m octa box. fill is in 1.2x0.8m retangular, both have internal baffles.
Am I to assume from the question that installing a ~100mm square of ND over a strobe inside of a softbox is not a common thing and noone has a rig designed to do it commonly availible ?
Aware of any negative effects that would make it non-advisable ?
