I recently bought a Sekonic L358. I think using a lightmeter is one of the next steps I need to take to improve the quality of my photos. I *think* I know how to use it, but would like just to run over the basic things of calibration with camera, taking readings and interpreting them in different situations, in some solid instructional material.
I will be taking some promotional shots for a hairdresser who is opening a new salon. I have the lighting worked out, and will go to do a dummy shoot in the next few days, before finally doing a shoot with the models. I will be using one light, with a reflector, and another light to light a background. I might also use a ring light for face shots.

Nice to see someone truly interested in the use of a handheld meter.....
Much appreciated, Art! I'll look a these. I did of course do a bit of a search myself, but what I found was arguments for using a meter, explanations of terms, but nothing like: first, do this, then do that, and so on, with the reasons and decision options along the way.

If this shoot is during the day, you may need to consider light coming from any windows. I would suggest turning off any other lights, except for any visible tungsten fixtures where I would install daylight compact flos. You want to keep to a single color temperature if at all possible (unless this is for B&W printing.)
The Sekonic L358 is a classic multi-purpose light meter and capable of handling your needs.

Thanks for these links, Ziggy, though I have had a look at everything on the Sekonic site. I do understand the meaning and use of incident and reflective measurements. While it was very interesting to hear those guys talking about their work and see their pics, those vids do not demonstrate basic techniques for the lightmeter. I did also see a youtube vid, which showed making just one pic with a different brand meter, which obviously was limited.
I'll check out the other links, and I much appreciate your kind help.
Yeah the vid is good for seeing someone showing the meter fitting into the workflow of an actual shoot, and it's clearly explained. Thanks again, Ziggy.
One thing that got by was that at the start he wanted an aperture of f8, but in the end he was accepting apertures up to more than f14 from the meter. So what happened to his original target aperture, and isn't f10 and above getting into a risky area for image quality?
Couldn't he have adjusted ISO to control aperture better while still getting the right percentage of flash and the target 1/60sec shutter speed?
Another puzzle to me is why he set the flash settings using the controls on the flash rather than on the camera, in the flash menus?
And a third thing which is not clear to me is why you would choose flash on manual rather than eTTL?
Any help for me to understand these issues would be great. Thanks!

This one is easy. Any time your subject and lights are static, you'll achieve far more consistent results using manual flash. ETTL changes flash levels all over the place with the slightest change in framing of the scene, and seemingly sometimes for no reason at all. You'll also want to use manual if you're using non-ETTL flashes of course, like studio lights or cheap after-market flashes (which I do). And of course if you're using ETTL, you have no use for a flash meter whatsoever.

Thanks, joel, yes I see your point.
However, I still don't entirely understand since when using eTTL you can still use the camera in manual, so you decide on ISO, aperture and shutter speed. Why not use the lightmeter to help you?
I suspect something in my thinking is ass about (excuse the French) but don't know what? The reason I needed to get down to basics.

But the light output from the flash in ETTL WILL VARY depending on the reflectivity of the subjects that it is pointed at, or precise framing - even though the aperture, ISO and shutter speed are fixed. But the exposure will VARY due to the varied output from the flash in ETTL.
As Joel said, and I have said repeatedly, when YOU ( the shooter ) control where the subject sits or stands, and the distance from the flash to the subject is fixed, non-changing, shoot with the camera in Manual mode and the Flash in Manual mode as well. You will get the most consistent frame to frame exposure you can get.
Use ETTL for candids of moving kids, people, etc where you cannot dictate their distance from the flash, and the distance varies from second to second.
Both Manual and ETTL flash are great tools, but each have their advantages. Take advantage of them!

When shooting the camera in manual exposure, you have two issues to control, ambient light, and the flash. For controlling the ambient light, I always use my in-camera light meter. You're right, you could use the flash meter to help you there, but the in-camera meter is more expedient. The flash meter is most useful in measuring the amount of flash. So if you're in ETTL, you've just eliminated the purpose of it.
Thanks Pathfinder and Joel. Yes I certainly understand what you say. Now I have used the lightmeter a few times I am beginning to see the trees from the wood, so to speak. I calibrated it with my camera this afternoon, it was giving me readings which were causing my camera to underexpose slightly, going by the camera's histogram for an 18% card. There's no doubt the meter makes a big improvement to the quality of shots, and I am also setting custom WB whenever possible with a Lastolite 18% card. You really see the best from your camera these ways.
