Travelling Light: Using Light to Create a Dramatic Portrait (Part 2)

Acting All Snoot-y: Using a Snoot

20100501_jivebar_0026-EditA snoot (click on the image on the left for a larger view) in many ways is similar to a grid in the sense that both restrict the light that’s coming off the source. This particular (usually tunnel-shaped) attachment allows you to control the part of the scene that is lit by focusing the light in the direction in which the snoot is pointed.

This is one of the first attachments that I made myself using some illustration board, duct tape and hook-and-loop fasteners. A DIY project that led me to finding an alternate use for plastic placemats, and one that I would’ve happily continued if not for my wife’s sudden realization that our placemat numbers were dwindling.

Four? Didn’t we just have three of these?’

In this environmental portrait of a student working in the lab, I used two snooted flashes to cross light the subject. Working at ISO 400 and shooting at 35 mm (on a crop body), an aperture of f/5.6 paired with a shutter speed of 1/100 s allowed the background to become underexposed. Aside from providing contrast, this allowed me to minimize the contribution from ambient light, which came from overhead fluorescent lamps (humming and unflattering light sources that they are).

Shooting at 42 mm at ISO 400, an aperture of f/5.6 to keep the students behind the main subject (on the right) from falling out of focus and a shutter speed of 1/25 s allowed some of the ambient light to bleed through the scene. The effect of the snooted flash here is subtle (I hope) as I used it to highlight the student on the right to make her pop out of the frame. Also, the flash is gelled with a 1/4 CTO strip to bring out the warmth in the skin.

A snoot is definitely one of the cheapest ways to modify light coming from your hot shoe flash as you can easily make one with materials that are readily available. And it gives surprisingly great results, so think twice before you decide to dispose of your old plastic placemats.

  1. I've been looking for this post since you changed the name of your blog. I just love the conversation you had with Susan regarding the dwindling numbers of placemats. :)
