We have done a number of articles with different flash heads but we have never gone into the detail of how to set them up and make them work, this results in emails that we sit and explain all the details to people. So today I am going to go through how to setup these studio flashes and connect them to your camera to get the results you want.

First off you need to realize that studio flashes like the PhotoBasics StrobeLites are not automatic like the on-board or accessory flash on your camera. A studio light doesn’t know what you are trying to do and will not adjust itself for the camera settings you have dialed in. You also need a means of firing the lights off when you press the shutter, all that and more will be covered in this article.

Connecting the lights to your camera

PC Sync port on Canon 30D

The first thing we need to do is to connect the lights to your camera, for this we are going to need what is called a PC Sync port. On most Canon DSLR’s the PC Sync port is on the left side of the camera under a rubber flap. In the image here you can see the PC Sync port and the end of a PC Sync cable. In my typical setup I will have the main light plugged into the PC Sync port to fire it and the other lights will automatically fire at the same time because they have a built-in optical slave that will fire the flash when another flash is detected. Since this happens far faster then the mechanical shutter, the effect is that all of the lights fire at exactly the same. There is a limit of how fast the lights will sync to the camera but we will address that in a moment.

Weim Hot Shoe Adapter

If you are unlucky enough to not have a PC Sync port on your camera then you will need to purchase a hot shoe adapter. The recommended one is the Weim Hot Shoe Adapter which sells for about $50 at most places. This will got into your camera’s hot shoe (when an acessory flash plugs in) and has a PC Sync output port on it.

As I mentioned, the lights do have an optical slave so they will fire when another flash is used so you may think you can just use the flash that is built into your camera to fire off the big lights. While this will work to an extent, the problem is that unless you know how to adjust your flash’s output compensation, the flash is going to fire at a level that your camera expects will be correct for the given light, when the big lights fire along with the built-in flash, your subject will no be over-lit and the scene becomes overexposed.

The opposite end of the PC Sync cord plugs into the back of the light. In this image you can see the 1/8th inch mini plug port on the bottom right hand area of the strobe head. With the camera and the lights connected, you are all ready to take some amazing images right?

If ONLY it was that easy. Now actually comes the hard part, figuring out how to get the light set right for a proper exposure. Hang in there, it won’t hurt too much.

Getting the lighting right

Output Adjustment Dial

Nice, quality studio lights make your lighting easier right? I wish! In the last section I explained that your on-board or accessory flash will meter the scene and use the appropriate output for the exposure metering, not so with studio lights, at this point you are full manual.

On the flash will be an adjust dial to control the amount of light output. On the StrobeLites this goes from full power down to 1/4 power given you two stops of light output control. If you have a light meter and know how to use it, you have all the tools you need to get the shot right the first time. If you don’t have a light meter then you will need to continue reading.

Since I shoot with he same lights, in the same studio, with the same basic setup the vast majority of the time I know the basic light setup that will work without have to take too many test shots, I can usually get it dialed in within about three shots.  A key thing to note is that your meter in your camera is basically worthless at this point. You are going to want to shoot in manual mode otherwise the camera is going to try to adjust your settings for the metered light. In manual mode you have total control. So where should you start?

For most of my pictures I start with the following basic settings:

ISO: 200
f/Stop: 11
Shutter Speed: 1/200th second

In fact, those are the exact settings I used for the previous pictures in this article so far. Why these particular settings? For one, I like shooting at ISO 200, I like the results I get at that speed, f/11 is my normal aperture setting unless I am going for a particular depth of field effect. That leaves two ways to adjust the amount of light I need. I can either adjust the shutter speed or adjust the light output of the flash. You may think that you may want to go with a faster shutter speed to make sure you dont introduce any camera blur but in most cases you can’t shoot any faster than 1/200th or 1/250th depending on your lights/camera combination. With the PhotoBasics StrobeLites and a Canon 30D, I have never had an issue at 1/250th but I like the extra margin of safety of using 1/200th. Let’s take a look at what happens if you shoot faster.

Out of Sync Image

The image shown here was shot at 1/640th of a second, while this would be perfect safe if I was using the Canon 580 EX flash, the StrobeLites cannot sync with the camera at that speed so what happens is that the strobe went off too late causing the image to be partially cutoff by the closing of the shutter mechanism. Because of this issue we are limited to speeds of 1/200th or less so I usually will stick it at 1/200th and be done. That leaves adjust the light output higher if I need more light or using a lower output or a slower shutter speed if I need less light. Knowing that the only things I will need to adjust are my light output or shutter speed I have really reduced my possible settings from a handful down to basically one, and its either shutter speed or light output.

Since most of my shots are product shots, the lights are generally pretty close to the objects so I will start at a very low power output of the flash, if its too bright at the lowest setting and I am already at 1/200th of a second the only way to cut down on the light being captured is to move to a smaller aperture setting like f/22. If the light isn’t enough I can just reach up and dial in more light or use a slower shutter speed.

With a little practice and a handful of confidence, you will be getting your lighting dialed in within a few shots. Take your picture and then look at the histogram of the image on your LCD of your camera to double-check the exposure. If its too dark, bump up the light, if its clipped out, dial down the light. Nothing will beat just a bunch of practice with your own lights/camera/lenses/environment to get you familair with how your lighting setup will work the best and soon you too will be able to get it dialed in perfectly within just a few quick test shots.
