Adam, I commented on another of your posts and you are working hard at progressing. Good job. I recommended a meter in another post and you didn't ask the usual questions, dome in or our, point at the lights or the camera. Here's something you won't here many places. In studio, pointing the dome in at a particular light will work since you can turn off the fill for example. Outside, how do you turn off the sun to get a reading of the strobe? You can't. Pointing the dome at the individual lights to measure the ratio is the SOURCE METHOD. However, out doors as indoors when you have the main and fill on for the shot, the fill overlaps and adds to the area illuminated by the main. The ADDITIVE METHOD takes that into consideration. You can use the same method inside and outside. First take a reading from the fill side dome out pointed to the camera. Then take a reading from the area on the main side where both lights overlap with dome pointed to the camera and both lights on. Adjust the main to get the desired ratio/difference. You set your camera to the additive reading from the main side. Find the ratio you like and start there in the future. The classic 3:1 ratio taken by the source method is 1 2/3 additive so ou might just start with 2 stops and adjust. I like being able to shoot at particular apertures so if I want to shoot at say f/11 with a 3:1 ratio, , I set my fill 2 stops under then just power the main to f/11 and I have the aperture I desire. Now, outside, you meter the ambient on the shadow side with the main strobe off, then power up the strobe and take readings from the additive area to give you that ratio you like. Also, if you want to use the strobe as fill, say 1 stop under, look for the percentage strobe contribution to ambient reading that Sekonic's give. A stop is half or double the amount of light, so that means the main gives one stop, ie 2 units of light and the fill 1 unit, half as much. That is 1 unit of fill from the strobe of 3 total units or 1/3. Look for about 30% flash contribution. As for accents and hair lights measure pointing at the light. Hope that helps.
