There are always several equivalent exposure combinations, and the skill (to get out of Full Auto mode) involves knowing when and why you might give preference to each of those three factors (when to do what?) Fully automatic cameras do not aid learning this. Then 'Crop Factor' won't include the individual words like 'rain is a factor of crop growth'. That can at times improve search results. 'Triangle' is the name used, but it is figurative, cute but possibly confusing, since there is no triangle, there are just the three interacting factors controlling exposure (f/stop, shutter speed, and ISO).Д«TW, in 'things we need to know', if the Google search terms are actually a known phrase, like 'Exposure Triangle' or 'Field of View' or 'Extension Tube Formulas', then add the quotes around your search phrase so Google will search for it as a combined phrase. See Google at 'Exposure Triangle' for more basics of learning this, which is about the first elementary concept photographers need to know about Exposure. There are several possible combination choices (Equivalent Exposures), but usually one best one for the current scene. Exposure of a photo obviously depends on the combination of the three factors, f/stop, shutter speed, and ISO. Learning exposure is an extremely important initial skill in learning photography. And the EV Charts just below it (with third stops).ДЄn Exposure calculator to compare EV value and stops difference for any two camera or meter exposures is on the previous page.

') Д¬onsole.WriteLine('The application started at times for an event to complete.', numWaits) When the user presses the Enter key, the application calls the Stop method before terminating the application. The event handler displays the value of the ElapsedEventArgs.SignalTime property each time it is raised. The following example instantiates a object that fires its Timer.Elapsed event every two seconds (2,000 milliseconds), sets up an event handler for the event, and starts the timer.

Stops raising the Elapsed event by setting Enabled to false.
