Are you thinking about starting a 366 project next year? Consider a little space planning before you get started.
How much space will you need?
Take a look at your average photo size. Multiply that by 366 and you have the minimum amount you will need available on your hard drive or, ideally, an external hard drive.
I know that my Raw images are about 25 mb. Converted to 4×6 jpegs they use about 2mb.
I can then estimate my annual total.
(RAW + JPEG)*366
(25mb + 2mb)*366 = 9,882mb or 9.82 gigabytes
Of course, I’m going to take more than one photo of the day. Events, photography walks, and special photo shoots will take more space. Some days will have just a few photos and some days will have only iPhone photos. If you shoot a lot of low light, high ISO photos, you will have larger files. On average I take about 18,361 photo per year. That is about 459 gigabytes per year.
Knowing that I need about 500 gigabytes annually lets me judge my external hard drive space. I can calculate whether it will be enough for the year.
I have found, through past experience, it is much easier to know this now and adjust. It is no fun to try to solve it when the space is alarmingly low. I currently use a Seagate FreeAgent GoFlex Desk 3 TB USB 3.0 External Hard Drive STAC3000102.
I will start my 366 project knowing I have enough space for the year!
