A Malaysian Tiger surveys his environment in the San Diego Zoo. This image in a raw file consumed about 25 mB of space.
The reason I am impressed wouldn't carry near as much weight if it wasn't for the fact that I am a Prime Member of Amazon.
For the prime member, Amazon offers unlimited storage space for your full resolution full size photo files. You heard me right, unlimited storage. And they accept a wide variety of image file types. All are imported natively with no algorithms to compress space.
Recently I backed up a bunch of DVDs that i stored images on for about 10 years. I transferred the files to a four-terabyte external hard drive and then uploaded these files to Amazon. Now I have a hard copy plus cloud backup.
Once in the Amazon server universe, their system software reads your EXIF information and chronologically categories the files by year and month, making it easy to locate based on what, when and where I was on certain times.
Amazon also has an AI component that reads the images and groups them by subject matter. This gets interesting as I drill through the titles (eg. “mountain”, “ocean”, “plant”, etc.). Most of the time the software is pretty close to the actual subject matter. Even more enticing is the search function; let’s say a client needs a selection of photos of umbrellas. Type this into search and the software queries all of your photos and displays a selection of umbrella images. I realize Apple Photos and iCloud have a similar search function, but I don’t feel its as robust as Amazon’s.
Another interesting facet is the "On This Day" feature. Every day I am presented with all photos tagged with that date for as many years of data I have.
Finally, you can create albums with ease, and share seamlessly with your people.
In summation, Amazon Photos is a very great choice for cloud storage. In particular, the unlimited full-resolution capacity if you are a Prime member, along with the categorization and search features. Otherwise, you can still use the service but you will be limited to 5 gb of space.
