20D with studio strobes on sync cord


I used a 20D for most of my portrait shooting and I'm hoping to get some studio strobes soon. The thing I'm unsure about is what I should do for metering. I just got a Sekonic L308S flashmate which should work well, I just need to know how to trigger the flashes. No, I'm not going to spend a few hundred more dollars at this point to buy a shot shoe radio trigger...

I'll probably be using a pc cord to fire the flashes for each shot but I don't know how I'm going to meter. Should I just use the ability to throw away crappy shots with digital and just snap the shutter to make the flash go off and take a reading, or does anybody in this position know if you can trigger the pc socket to sent out a flash signal if you hit the flash exposure lock button? What if I were to get one of those things that attaches to the hot shoe for those cameras without a pc socket? Will that let me be able to trigger the strobes?

If I haven't said it clearly enough, I would have to hold the meter up to the face of the model and have somebody else trigger the flashes by pushing the test button on one of them, which isn't practical.

If you can share your knowledge or perhaps what YOU do to trigger your strobes and to meter, that would be great.

Thanks!

Andrew

  Pc cord should plug into the light meter. Fire the flash with the light meter.
Quick check thru web and it does have a pc socket. It also has cordless. Just push the test button on cordless mode and leave it at the spot you're measuring. It waits till you go fire the flash.
You buy it used?

  >>"You buy it used?"<<
i.e. do you need the instruction manual for the L-308S? Available at Sekonic's website:

  Hi Andrew,

I guess I don't understand why all the hoop jumping.
Most studio strobes have slaves in them..Just use your on cam flash to trigger them..dial down the on cam flash so it won't contribute to the shot.
Have your subject hold the meter..what's the big deal?

Personally, I despise sync cords..just one more thing to trip over. LOL

  Yeah, I know how it works and all but I don't want to have to make somebody work, other than posing, while being photographed. Even if it's just holding a flash meter. I asked a few people to hold a gray card before and I really didn't like that.

About firing the flash with the light meter through the sync cord, I just don't want to have to unplug it everytime I take a reading and plug it back in again.

I want to just be able to go up to the person, hold up the meter without having the meter on the cord, and be able to set the flashes off without going back and hitting test. So that's why I was asking if the FEL either through the sync or through the hotshoe would work, if anybody knew.

  Well Andrew:

If you don't want to be inconvenienced with the PC cord, and dislike asking your subject to hold the meter, which probably isn't too professional anyway, try this approach.
If you already have a posing chair/stool or at least have a fixed background so you know where you are going to place your subject before hand, then just set your camera to self timer. Walk your meter to where you subject will soon be, and wait for the flash to fire.
So long as you don't change the distance between your lights and the subject, then your exposure should be the same for the entire shoot.
Another idea, particularly suited if your setup is permanent, would be to measure off, in feet, from your subjects position to your flashes, main and slave. Using tape, in a semicircle, with your subjects position being the center, you can lay out flash positions on the floor. That way, even if you move your lighting side to side, you can, at a glance on the floor, maintain the same distance between your flash and subject so you don't have to remeter everytime. In most instances, your subjects feet won't be in the picture, so neither would your markings. And even if you did a full length shoot, the markings wouldn't even start till you were a good five or six feet at the least, away from subject position.

  Dang, exactly how far do you have to walk from your lights to what you're taking pictures of?

  I used some strobes before, along with a camera that had a radio slave so I was able to just keep a hold of the camera and hit the test button ON THE RADIO SLAVE. That means that I can hold the meter myself, turn it on automatic detection, and hit the test button right in front of me. Of course, I won't have a ton of room between me and the subject but sometimes I might use a longer lens for headshots. Recently it's been my 200mm lens for lack of a better range.

As a side note, I won't have a permanent studio since I'll have to set it up each time I need to use it, plus I want to use them for location shooting as well. That's what I seem to have liked the best since I dont' have to buy all the props and backdrops for more variety.

What I'm wanting to avoid is just having to unplug the cord from the camera and put it into the light meter since I take a new meter reading anytime the subject moves closer to or further from the lights. That cound mean a bunch of cord changes and like I said, I don't have the money for a radio slave. Do you think the FEL button on the 20D will set off the pc socket connection? I also have a hot shoe mount pc connection accessory if pushing FEL will also sent a signal through the hot shoe to flash.

If I were taking photos that were like senior pictures where they just have a single setup in a studio and I could predict what I needed to do since I would always be in the same place, I wouldn't worry about it, but since I've needed lights at times and have been varying distances away, I don't want to have to move around too much.

  I see the FEL button makes a pre-flash go off. I doubt that will do anything with the pc connection. My guess is it will only do something with the built in flash, or a Canon speedlite. And in that way, you're ending up firing the strobes with the strobe's own slaves.
Since you want to use the camera to set the strobes off, why not connect the cord to the camera, and just use the camera on rough small jpegs. You'll use up very little space on the card.
