Real-Life Math
Numbers are all over the place when dealing with cameras. As a professional
photographer, you'll need to know some math. So, you've studied up on aperture,
shutter speeds and focal length.
You're working as a commercial photographer,
and your latest client has you taking a series of photos for a local shopping
mall.
You shoot a series of photos based on what the client is looking
for. You are getting the photos ready for the client when they tell you that
they want the photos delivered online, through their ftp server. You get the
info from them and get ready to upload the photos.
The only problem
is the photos are too big to upload in one folder, which would be the easiest
way to do it. You have 210 photos, and you don't want to upload each one individually.
Each photo is 2.5 megabytes in size; the maximum you can upload at once is
10 megabytes. You consider uploading four photos at a time, but you're worried
you'll miss some in the process. You're also concerned about the time it would
take.
Then you realize another option. You can make compressed zip
files of the photographs and upload those. Each photograph, when compressed,
is only 3/4 of a megabyte. You decide to make compressed files containing
several photographs and upload them.
How many compressed files will
you have to make, bearing in mind they can be no larger than 10 megabytes?
