A project operates within the triple constraints of time, cost and scope, where as photography operates under the triple constraints of aperture, shutter speed and iso. The triple constraints are inter related. When we deal with time, that can impact cost and scope. When we deal with scope, that will impact cost and time. Similarly, when we deal with shutter speed, it can impact aperture / iso. These are all connected, and unless we know how to juggle these constraints efficiently, we cannot be good at our job. A Microsoft project or primavera, for that matter every project management tool out there will work out the critical path for you, and if you want to optimise it, then one need mastery over the triple constraints of time, cost and scope, so that they can crash, fast track, introduce leads and lags efficiently to get that perfect schedule. That is the case with photography as well. Every other camera has the auto mode, which will help to take reasonable photographs, then, if we have to really take a perfect shot in adverse conditions, then we have to rely on the manual mode, and that requires mastery over aperture, shutter speed (time), and iso.
Here is my photograph for you, which was taken in really low light, in manual mode (slow shutter). Hope you will like it.
