693 Sharpening molecules with High Pass

- [Instructor] In this movie we're going to take…our very colorful as well as…very softly transitioning molecules,…and we're going to give them more tactile edges…with the help of a couple of high pass layers.…Now something I want you to note about this image…is its file size in memory,…and so take a look at the doc value down here…in the bottom left corner of the image.…Notice that it shows up as 16.3 megabytes…before the slash, and zero bytes afterward.…Now typically what this is telling you…is the size of the image flat in memory…if it were expressed as a flat image file,…and then the size after the slash…is the size of the image in memory…including all of its layers.…

So why is the image so big when flat…and so little when you take into account…all the layers?…Well we can see the reason…by twirling open one of these groups here,…and then twirling open one of the groups…inside of it, and then notice,…each and every one of these circles…is a vector base shape layer,…which takes up very little room in memory.…Also worth nothing is when you save this file…
