Perhaps you are interested in building your very own home photography studio. Let's see what the best ways are on how to go about this.
First and foremost, you're best off using a fairly small sized room with neutral white walls. White walls ensure that the light remains uncoloured, so that the person you are photographing doesn't get subjected to any coloration by the light (imagine if your walls were neon yellow for example...).
You could use a soft box, an umbrella, or both in the studio. A soft box is a small box that fits on top of the flash, the small flash tube shines out light, which is reflected from the insides of the walls of the soft box and then passes through a translucent material that covers the front of the soft box, dispersing the light in all directions.
An umbrella is very similar to a soft box, the only difference being that some of the light from the flash can pass through it, and the remaining light will reflect off it. You can use it both ways to get different lighting effects. When you put the umbrella onto your flash head, you will have something known as a spill kill. It is a round piece of metal which goes around the end of the flash. It is called a spill kill because it prevents light from spilling out past the umbrella. This stops light from shining onto the walls and the ceilings, which can totally mess up your photography efforts. The whole purpose of a home studio is for you to be in control of the light.
Let's have a quick look at the differences between the light coming from the soft box and the light coming from the umbrella. Flash heads have what we call modelling lights, which are simply tungsten bulbs that are always on. By adjusting the output you can make the light level go up and down. It enables you to see what the light is going to do at different outputs. As you adjust the exposure you can see how the shadows change around the model or object you are shooting.
If you are choosing to work with a flash, it will be necessary to use a flash meter. There are trial and error ways of doing it but they are not accurate and it would require a lengthy explanation. Firstly, you have to set the ISO speed on your flash meter to match the ISO speed on your camera. Set your flash sync speed to be fast enough. To do that you would have to find out what the sync speed of your camera is. Don't point the invercone directly towards the flash. It is best if you point it at the position of the camera. If you're buying a home studio kit, it will probably include 200 or 400 watt second lamps. Using the flash meter you can find out the aperture. F8 is a decent aperture to use.
If you're using an older set of lights, the voltage may be different to modern electronic devices and can break your DSLR, so it is recommended that you don't connect your camera directly to older lights. Instead you can trigger photoelectric cell triggers on your lights using a pop up flash on top of your camera. So that this doesn't interfere with the lighting of the photo, you will be able to adjust the flash on your camera to be a tiny fraction (say around 2%) of its normal output.
By working with an umbrella instead of a soft box, we can allow some light to penetrate through the umbrella, bounce around the walls and ceiling of the room and make a softer overall lighting effect in the room, rather than have almost 100% of the light reflect back onto the person, people or subject we are shooting (as would be the case with a soft box). The shadows on the model's face will not be as strong when using an umbrella as they would if you use a soft box.
If you turn the light around to point directly at the person or group of people, with the umbrella between so that the light shines through the umbrella, the room will be a lot brighter than before. You'll need to readjust your exposure settings before taking the picture. Doing it this way will obviously create softer lighting than if you just use the soft box, but the lighting will still be harder than having the light bouncing out of the umbrella (with the flash facing away from the person you are shooting).
A common way of setting up your lighting is 'flat light', which will remove textures and shadows by using two, three or even four flashes. Shadows on a person's face will make their wrinkles and imperfections stand out more. Having one light shining towards the subject from one location and another light from another location will help to soften up the shadows. You might decide to let some of the light shine off one of the side walls. If you watch out for these small details you will be able to spot some very interesting results.
To set up the exposure with multiple lights, you'll need to do one light at a time to guarantee that the light is even from each light source. In this situation, I recommend that you do point the invercone at the light. If one is around say F8 and the other is about F8.5 it will be good enough, because the difference is so small. If you're lucky enough to have lights that are on sliders, then by simply moving them forward or backward by a few inches will enable you to make tiny changes.
If your aim is to create some soft shadows, you can use a technique known as Key And Fill, where you basically have a light that is the key light (your main light), which will cause shadows to form on the model's face. You can then use the other light to soften those shadows. It is best to start off by setting up the key light before the additional light. This light should be almost in line with the position from where you position your camera. After that, set up the fill light to soften the shadows. You should experiment with the location of the fill light, but it will probably work best when pointing toward the model approximately at 90 degrees to the direction of the main light. If the key light is roughly F16 for example, and your fill light is around F8, this should work quite nicely.
The final thing to check is the average exposure. Turn both lights on, make sure you're not standing in your own light, then measure the exposure at the place where the subject is positioned with the flash meter. You can then set this on your camera.
If you use a longer lens and standing slightly further back, you can guarantee that no unwanted light enters the camera directly from the lights.
By spending the time to learn how to meter it and taking the time to set it up, you know that light will stay constant at least a few hours, unlike natural light from a window which is constantly changing with the direction of the sun.
