Sorry it has been a while. School is out and 2 kids are time consuming. Today is just a tip for a pain in the but process I have been dealing with. I have had many times where I took way more pictures than needed to get the shot that I wanted to capture. Like blowing out candles during a birthday party, hitting the ball during a game, a first kiss during a wedding, etc... Taking a plethora of pictures in this day and age is easy. It is also easy to let a few days build up then a few weeks then a month or two and if you are not careful it can turn into a year or more. In years 2014 and 2015 I took over 13000 pictures each year. Realistically at most about half of those were good quality, in focus, and not a near duplicate image. That brings it down to 7500 each year. While spending hours going through and deleting these I realized that it would have been easier to go through them after uploading. With our megapixels increasing hard drive space becomes limited, a 2 gb card will hold around 115 raw files from a 16mp camera or 57.5/GB. One terabyte would only hold around 58,000-59,000 of those same files. 16mp isn't even a large image size either anymore, a quick search showed a 50mp camera from Canon. My advice here is to delete the photos that aren't your best after uploading them. It takes a few minutes and give you time to enjoy your photos. If it becomes a habit then you don't have to look through thousands of photos all at one time because you are running out of storage space.
These two images were taken 1 second apart and there were 3 captures between these images and about 20 captures total. I kept five or around a quarter. Delete, free up some space, grab your camera then go out and shoot.
