Personally, I’d recommend you use modifiers– these will help soften the light for a more flattering effect – and grabbing a pair of similarly sized softboxes is a great starting point. It’s easier to control, and doesn’t require any holding–though if you do go with a reflector, you can always have the model hold it, or an assistant of some sort. The acceptance angle is determined by the effective numerical aperture of the FACED mirror pair, given by \(NA \approx \sqrt {L\alpha /2S}\) 24.

Butterfly lighting and clamshell lighting are often discussed together, but they’re two very distinct lighting patterns. At this point, you should have two lights sharing the same vertical space, and the light on top should be roughly two stops brighter than the light on the bottom.In this article, I explain the ins and outs of this simple – yet incredibly powerful – two-light portrait setup.

With a minimal amount of gear from just a single light, stand, modifier, and reflector to a two-piece studio kit, the clamshell lighting pattern is a good one for lighting newbies to try. Converting your shot to black and white will emphasize the interplay of shadows and highlights while potentially adding a layer of three-dimensionality to the photo. The titanium dioxide (TiO 2) nanoparticle in the phantom has an average diameter of 160 nm as characterized by transmission electron microscopy.By positioning lights both above and below your subject, you can illuminate the face more evenly and reduce harsh shadows.

g., speckle noise), these strategies are limited to sparsely sampling the imaged volume with a handful of light sheets.

A 45-degree angle is popular, though you’re free to experiment with slightly adjusted lighting positions for different effects. In particular, the current multi-light-sheet fluorescence imaging systems, including the recent advances in lattice light-sheet microscopy, commonly resort to coherent beam interference, beam split, or wavefront shaping (in the spatial or Fourier domain) 12, 13, 14, 15, 19. In the absence of an emission filter, the frequency-encoded light sheets directly reflect off the glass slide and are captured by the sCMOS camera in the orthogonal detection arm. This system is able to visualize the flowing microspheres (flow rate of ~20 µm/s) at a volumetric rate f vol of up to 13 vol/s (Fig. By the time you’re finished reading, you’ll know how to create clamshell-lit portraits like a pro (no matter your lighting gear!

In CLAM, we exploit this unique property to create an array of continuous-wave (CW) light sheets with reconfigurable density and coherency through flexible tuning of the mirror-pair geometry (e.Both types of lighting have their place, but clamshell lighting is a bit more broadly applicable, given the gentler result.
