Sunday's Speedlite Session: Mix Light



Generally speaking, you want only your added lights to illuminate the subject. However, there are times when it’s a good idea to mix light sources, either using daylight or room lights.

In this photograph, I mixed the light from a Westcott Apollo 28-inch softbox (in which I placed my Canon 580EX II) with the room light. This technique can be tricky.

Here is a link for info on the softbox:

Following is what I do in this kind of situation.

First, I set my camera to the Manual metering mode and set my exposure for the room light. Here, I wanted the room to be fairly dark. If I had wanted it brighter, I would either increase my aperture or reduced the shutter speed to let more light into the camera.

Then I take a test flash shot. If the light from the flash is too bright, I reduce my flash exposure, and vice versa.

Mixing the light is all about experimenting.


You can see that the original shot is a bit flat. My enhancements on the final image included enhancing the saturation, contrast and sharpness in Photoshop.

Explore the light,

P.S. Thanks, Peter!


I added the two above photos after receiving a comment from reader Peter Kremzar. Peter, thanks for your comment. I could not use that particular photo, but if you'd like to comment again with another photo, I'd be glad to share.

Basically, Peter, who has a good eye and a good understanding of speedlites, suggested using more lights to light up the background. Good idea, but this was a one-light workshop. :-)

Also, above you see how one can lighten or darken the background in Photoshop.

Thank you again, Peter. Good idea!

The angle of the softbox is different.

I think the background level is fine. Too bright in the second PS'd one. Competes with the model with all that ornate detail.

thank you for sharing rick! i'm a natural light shooter and beginning to use speedlights to further enhance my images. its always great to learn with one light first and get a better understanding of how its done.

one thing i noticed because im kinda new to off-cam flash is the triangle setup (camera, light and subject)...is this a basic setup?

reggis... 3 lights can be good... so so can one!

Personally I like the darker background myself, it has much more of a Victorian feel and mystery to it and seems to be much less distracting. I appreciate the learning tools.

Great shot Rick. I have the Apollo and it's a great box. Easy setup and very portable. That along with the Photek Softlighter II which I love gives you some incredible portable and easy setup options.
