WebWhen to use a lower f-number. Night photography, indoor shoots with poor lighting, and most environments where light is scarce are where low f-numbers come in handy. When you push the f-number down, your aperture widens and drinks in more light which, in turn, results in a higher-quality photo. When to avoid a lower f-number. WebF-stops only refer to the size of the aperture. Unlike stops of exposure, they don’t simply double or halve, but instead, depend on the f ratio. For example, going from f/2.8 to f/2 is …
WebA micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using … WebStudy with Quizlet and memorize flashcards containing terms like The word "Aperture" and "F Stop" mean the same thing., A low F Stop (ex. F/4) will blur the background & give us low "Depth of field"., A high shutter speed (ex. 1/1000th of a second) will: a) Will show blur in the movement of a subject. b) Will freeze the movement of a subject and not show any blur. …
