This is what’s helped me over the years in saving countless unnecessarily unneeded wasted frame shots. Because what most people also don’t know or realize, DSLR cameras have a life span. It’s in the shutter count and sensor usage that eventually needs to be replaced. Think of your transmission or clutch or even your engine in your car (they’re parts that unfortunately live off miles - and us photographers gear is like cars….(and in certain cases, some cameras are actually just as much as a small car). And YES, some of the cameras I shoot with, a new sensor alone costs over $1000 (that’s not including the service technician fee of what’s usually around $400)
