About this deal

Hence, CLAM could faithfully generate N ≈ 20–70 light sheets to achieve a 3D imaging rate of f vol = 1–20 vol/s. b) is determined by the thickness and separation of light sheets, as well as the optical transfer function of the detection objective, especially in the presence of spherical aberration, which is introduced to extend the depth of field (DOF) (as described below) 8.

Consequently, they necessitate serial beam scanning or dithering to effectively create a time-averaged superposition of incoherent light sheets 3. Given this improvement, CLAM also reduces the illumination power and thus the photobleaching and phototoxicity.If you shoot in RAW, and I highly recommend you do, you have the flexibility to photograph using your camera’s Monochrome mode and still convert back to color if needed. In this article, I explain the ins and outs of this simple – yet incredibly powerful – two-light portrait setup. A 45-degree angle is popular, though you’re free to experiment with slightly adjusted lighting positions for different effects. An indicator of clamshell lighting is the double catchlight in portrait subjects’ eyes, which looks simply amazing and really helps to make the images pop.

Placing a light behind the subject (that’s pointed at the backdrop) can create a beautiful cone of light that adds extra depth. If the effect is too strong and your fill light is obliterating the shadows, turn down the light power. It’ll give you images that work for pretty much every kind of situation, from glamour shots to family portraits to corporate headshots and so much more. The unique feature that enables parallelized 3D imaging in CLAM is motivated by the concept of free-space angular-chirp-enhanced delay (FACED) 23, 24, 25, which creates an ultrafast laser line-scanning action from multiple reflections of a pulsed laser beam between a pair of angle misaligned plane mirrors. Experiment with the shadows and angles, then simply add a fill light to achieve the clamshell look if you desire something softer.The image reconstruction in CLAM simply adopts the short-time Fourier transform of the frequency-multiplexed image data pixel by pixel, followed by standard Richardson–Lucy deconvolution. In other words, the maximum number of light sheets supported by the mirror pair can be flexibly adjusted by the mirror geometry (e. However, the available approaches are limited to incomplete parallelization in only two dimensions or sparse sampling in three dimensions. That’s why you need to add a reflector under your subject’s chin, or a second light, one that will push light beneath your subject and create a stunning result. The final 3D image is computationally reconstructed with algorithms that solve the inverse problem, leading to the limitations of a reduced lateral resolution and a high computational complexity.
