![]() ![]() It gives you the power of choice through information as opposed to just blind guesses (eg you've good light, a good shutter speed and a subject which isn't calling for a specific aperture - if you want to maximise image quality knowing where on the aperture scale your sweet spot is is important - just as it is to know where the point at which diffraction softening becomes too great for your own standards). In the end learning what the technical limitations of your equipment is, is an important factor. Myself - I try to learn a smattering of both and then balance each as the situations occur. Sadly compositional theory and artistic methods can be as alien to some as physics and computer tech is to others. The only firm similarity I can draw is that a lot who get wound up about the other side being wrong often don't actually understand what it is that they are reading. Suffice to say some get all wound up when people talk about photography in a purely technical and factual manner whilst others get all wound up when its all about art and nothing else. It does not store any personal data.I'll never understand either branch of the extremists fully. The focus size reaches the optical diffraction limit (i.e., a single optical speckle grain) if a sufficiently large number of input modes, NSLM, are measured, where the required NSLM is larger for. ![]() The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.

This is given by the famous Abbe’s criterion given by Ernst Abbe in 1873 as. This cookie is set by GDPR Cookie Consent plugin. For microscopes, the resolving power is the inverse of the distance between two objects that can be just resolved. The weighted-mean wavelengths were calculated using the equation: (2 (K alpha 1) + (K alpha 2)/3 This equation gives the K alpha 1 lines more 'weight' because of their greater intensity relative to those of the K alpha 2 lines.

This calculator shows a camera as being diffraction limited when the diameter of the airy disk exceeds what is typically resolvable in an 8x10 inch print viewed from one foot. calculates the theoretical spot image size for a given f-number.

Directly related is single-crystal refinement. Single-crystal X-ray Diffraction is a non-destructive analytical technique which provides detailed information about the internal lattice of crystalline substances, including unit cell dimensions, bond-lengths, bond-angles, and details of site-ordering. ![]() This cookie is set by GDPR Cookie Consent plugin.
