I'm new to the craft of indoor and studio photography. Can anyone tell me about the following things? |
1. I just purchased a flash meter. I'm assuming it should work with metering any flash or flash unit, am I correct? 2. What is the relatioinship between an external flash and flash unit? How do I get one to work in conjunction with another and how compatible are they to one another? Remember, I am a total rookie here. Please explain in the simplest terms possible. You did not mention whether you are using a film or digital body for recording images. Flash meters are not needed as much when shooting with a digital camera (what you see is what you get). The relationships between flash units is the same as the relationship between hot lights. There is a main (or key) light, some kind of fill light and then there can be combinations of other lights used to create a mood or light areas not lit by the main and fill lights that are important to the creation of the image. Outdoors we use fill cards or reflectors. Your second question is sometimes covered in a whole semester (or two) of an advanced college photo course and really cannot be addressed here. Some of the professional digital cameras have what is referred to as "flash command" modes where you can control up to three different flash configurations using the on-board radio channels that come with the camera body. Before you spend too much more money, visit a couple of local photo studios and have them give you a tour. You may learn a lot more in a shorter time. Most studios rent time to photographers who do not have a studio of their own. Typically you may spend a few hundred dollars for about four hours of studio time (this of course depends upon the equipment you use at the studio). The most important thing is to experiment with the lights and have fun. You might try to duplicate shots you have seen and like the way the photographer used the lighting.

You are buying all this equipment, it sounds like, and need to experiment with the more simple aspect of photography. SLOW DOWN and have fun! 1- Yes, most flash meter, can measure any other flash unit; some old light meters can only read sun light. 2- The relationship depends on what do you want to do as a photograper, and which flash units do you have. But may be you should read more and learn the basics; why to buy a flash meter when you are a rookie as you admit? Some colleges give short courses. Buy good magazines and books. And go to good photograpy sites. Welcome to a new world of photography! 1) Correct, a flash meter can read from any light source...whether it is an on-camera speedlite, off-camera strobes, or always-on studio lights. Most flash meters will have several modes to tell the meter when to take the reading: - wired mode: the flash is physically cabled to your meter. - wireless mode: the flash meter will be on standby and will record whenever you fire the flash...no special wireless hardware is needed...the flash meter will record whatever spike it detects (somebody turning on the room lights should not count as a spike.) You will most likely be using this mode. - incidental mode - this is where you manually tell the flash meter when to take its reading by pushing the trigger, but this mode is more for capturing ambient and constant available light - it cannot be syncronized with a flash trigger. If you are using natural light or always-on studio lights, you will probably use this mode. When using the meter, hold the globe by the subject's face pointed at the camera...have the subject hold the meter if necessary for the test shot. 2) Relationship between external flash and flash unit. I will presume you mean 'flash unit' to be the triggering device. In the Canon world, the triggering device may be a larger flash unit like the 580EX, or a trasmitter like the ST-E2...these devices act as the 'master' where they can trigger other flashes like another 580EX or a smaller 430EX (the 'slave'). A Canon or Nikon setup like this works through radio signals. With this setup, it is basically an issue of making sure the master and slaves are set to the same channels. The ST-E2 has the capability of establishing the lighting ratio between your main (primary) light and your fill light...e.g., let's say you want your primary light to be 3x brighter than your fill light. A Canon setup can be expensive and may not be the best value. And since you have a flash meter, you will probably want more control... A 2-flash setup like the Alien Bees flash units establishes your primary light as the master, which will trigger the secondary fill light via an optical trigger. When the secondary flash unit detects a pulse of light from the master, it with trigger will no noticeable delay...it works great indoors and there is no need to run cables from your primary to your secondary. In addition, you can add an unlimted number of external flashes like a backlight or hairlight as long as they have that optical sensor (even if it's a different brand.) You will probably need one wired sync cable between your camera and your primary...but that's all the sync cabling you'll need. This sync cable should come with your flash kit. If you want to be completely wireless, you will need to look into radio controllers (to go from the camera to the primary) such as the PocketWizard...but this is expensive.) With a PocketWizard setup, you can even take it one step further and have your flash meter trigger the flash units for a test reading if you install a radio transmitter on your flash meter (some of the Sekonic meters can do this)...but I think this is an expensive luxury that is not necessary. The Alien Bee setup does not have ratio control like the ST-E2, but as you get more experienced, you will appreciate the manual control. If purchasing Alien Bee lights or similar, I would finish off your studio setup by purchasing a set of medium to large softboxes that mount right onto the strobes. You can't do these with Canon speedlights. I prefer softboxes over umbrellas because of the softer light. You don't have to buy the softboxes from Alien Bees, but be sure the mounts are compatible if you go with alternate brands. I would avoid any studio lighting setup where the primary flash is mounted right on your camera...this type of lighting is too flat. Hope this helps Alien Bees: http://www.alienbees.com Your light meter will read ambient light hitting your subject, and flash light from your flash heads. You can get flash systems to work together by using slaves and a master either connected by a sync cord or by inferred. If i were you i would look into doing a photographers assistant course where all this will be explained. It is quite difficult to get your head round metering and setting your camera to expose correctly. |
