The future of photography technology will be as dramatic as the technologies we are seeing in smartphones and tablets. The computing power is doubling at amazing rates and the power needed to manipulate photographs is growing with it. That is so promising and yet not everyone has grasped that yet. I was reading an article about organizing your photographs and the author said to not download your blurry photographs. Stop right there! That statement is assuming a lot of things that are not necessarily true. First, it assumes that the picture is just one of many and no big deal if you delete it. Second, it also assumes that at no time in the future could technology advancements in photography resolve the blur problem. Because of better technology I have pictures that I have rescued this past year that I took 12 years ago. If that blurry image is the only one you have of something important then do not delete it! Have you seen the technology demonstrated by Adobe where blurry images are being corrected to an almost perfect image? I only delete pictures that I feel are duplicates and of no value regardless of the future. Yes, I have a lot more pictures I store because of that but so what? What is the cost of doing that?
Be very selective of the pictures you delete. I have gone back into my archived pictures more than once to process a picture because of what was in the photograph. I used 12 year old pictures of my house being built to see where the pipes and wires were at. I didn't have them in my "official albums" but they were still there on my hard drive. You never know what the value of a picture is until the day you want it or wish you had it.
I store all of my photographs on a single drive that is backed up by Carbonite and I also copy the "Picture" directory to a second hard drive. I do not want to lose my pictures regardless of their perfection.
