1. Re: Will my Photos fit on a 64-128 GB jump drive?
ssprengel Aug 10, 2014 10:21 AM (in response to pennipeter)No one else can answer this question for you. You have to look at the size of the photos on your hard-disk and see what the total size is and then buy a flash drive that is large enough to hold them. Larger flash drives are more expensive so there’s no need to get a huge one if things will fit on a smaller one.
Are you giving them your originals or are you going to work on them and give them saved JPGs after all your edits? What is the total size of 350 originals?

pennipeter Aug 10, 2014 11:05 AM (in response to ssprengel)Good point. Not giving originals ... Size I hope to be about 20 mgs each

ssprengel Aug 10, 2014 11:15 AM (in response to pennipeter)Are you asking for help with math? You’ve said you will give them about 350 photos and that you hope they are 20MB each. This works out to 20MB x 350 = 7000MB = 7GB, so you’re hoping they’ll be 7GB in total.
How much disk space do 350 originals take if you save them without doing any special processing? That should give you a better estimate than “hope they are 20MB”.
Doing noise-reduction on high-ISO images will make them smaller than the unprocessed version and sharpening will make them larger than the original, so depending on how much noise you are reducing and how much sharpening your adding they could be smaller or larger than the originals. If you resize them smaller as part of your processing then that will make them smaller. If you save them at a higher-quality setting than what your originals are compressed at then they would be larger.
These variations are why no one else can tell you what the final size will be though you can get a closer estimate if you do some simple experiments and check what the size is on disk afterwards.

ssprengel Aug 10, 2014 11:30 AM (in response to pennipeter)1GB = 1024MB and I used the approximation of 1GB = 1000MB but you get the idea. Since some of your photos might be 21MB and some might be 18MB the approximation of 1000 vs 1024 isn’t significant compared to the actual variation of the photos.
