How do I calculate one of the three inputs of the exposure triangle while using a 10 stop ND and flash?
How do I calculate one of the three inputs of the exposure triangle while using a 10 stop ND and flash? I’m having trouble phrasing this. Basically; I have a ten top ND filter. I’d like to hold ISO and fstop at a d specific setting and have the shutter speed open for a certain time without over exposing the picture What math, formula, or tool can I use to know how long I need to expose for?
