View Full Version : Studio lighting using multiple speedlites and transmitter

Hi -

I have a D60 along with a ST-E2 transmitter and two speedlites (550EX and 420EX). I also have two lightstands and two umbrellas. When I invested in this equipment, my hope was to produce studio-quality lighting that was relatively affordable and portable (my main interest is children's portraiture, and I work mostly on location). Up until now, I have worked mostly outdoors using available light, so flash and studio lighting is still new to me.

I initially started out with just one flash and the transmitter. When I bounced the flash into the umbrella, all of my pictures came out looking over-exposed. So, I turned the flash compensation down about - 1 1/2 stops and seemed to get better results, but still a little hit and miss. Now that I have two flashes, I seem to have the opposite problem - everything looks underexposed, even when the flash compensation is at 0 or adjusted + 1/2 stop. Yesterday, I realized that the transmitter seems to be triggering the 550EX and then there is a slight delay before the 420EX fires. No wonder my pictures all look so dark. Any thoughts on what might be causing this to happen?

And then my next question: If I set the camera on AV mode and choose an f-stop of f-8 for example, I get a VERY slow shutter speed in low light situations. If I set the camera on Program mode, I seem to get f-4.5 at 1/60 regardless of whatever ISO, which doesn't give me enough depth of field or a fast enough shutter speed to capture quick-moving kids. I called Canon last week to ask them about manual settings, and was basically told that the E-TTL system is meant to work in full auto, and that the Program mode was my best bet. I am currently taking a studio lighting class, and would like to achieve the same consistency with my Speedlites as I can with strobes, but just don't know whether it is possible with this equipment. I would appreciate whatever input anyone may have.

Thanks - Heather

I'm not sure why one speedlite is delayed in firing. I would ask canon on that one as they are the ones who claim you can mix and match with any speedlite capable of being used that way.

As far as your other issue, you need a different lens to achieve your goal of reasonable shutter speeds. Try the Canon EF 50mm 1.8. Its less than $100 and achieves astronomical quality for the price. It will allow you to take pictures in conditions thought impossible without a tripod. On a 1.6x body, you'll get around 80mm which is perfect for portraits.
