Lighting a science lab


I love shooting in science labs.  I enjoy learning what the scientists and engineers are working on and creating that will impact our lives in the years ahead.

Here I used two color gels to help communicated "science." I used blue on the background and red on the foreground.

To get a gel to be the same color it is in the shot it needs to to -2 stops darker than the main light on the subject.  So here the main is f/11 and the background blue is metering at f/5.6.  The same for the foreground red at f/5.6.

You will notice the power for the blue is full power.  The reason for this is the blue gel absorbs more of the light than red does.

The main light is a 30ยบ grid on a monobloc. This is the keep the light from spilling over onto the red or blue and watering down the light.

    Stan,

    I really enjoy these short, detailed descriptions. I've always been a fan of your work and after following you for 6yrs I'm still learning something new from nearly every post you make.

    THANK YOU!

All comments are reviewed.This is done primarily to eliminate spamming. Please be patient, I maybe on assignment and unable to review right away.

But to increase meaningful conversation, sometimes it’s necessary to reduce the not-so-meaningful bits. Here are the kinds of things we’ve been deleting in recent posts. Please avoid these types of comments:

One-word comments like “Cool!” or “Thanks!” While we appreciate the congrats, we’d love to hear more about what exactly you love, and (even more importantly) why.

Shameless self-promotion. Comments that contain links to your site within the body or otherwise encourage folks to visit your blog are a no-no. If you’d like to increase traffic to your blog, there are other places than here to do that.

Multiple comments by one author. We’re glad you want to be engaged, but please give others a chance to speak, too.

Really long comments. Let’s just say that if you need to take more than three breaths to read your comment, it’s probably too long.
