First, holo polishes are those that have an overall rainbowy, prismatic effect. In direct sunlight, it will have a base color but then a lot of other colors too. Here's an example of a holographic polish, one of my faves, OPI My Private Jet:
By contrast, polishes that have holographic glitter just simply have multicolored glitter but they don't quite create that special prismatic effect that holo polishes do. Take, for example, this red Opera polish
The glitter kind of reminds me of sprinkles, especially in this picture:
Also, success! I found a full-size Opera bottle picture for reader Pixie. I didn't fail after all
If you're wondering why these pictures look a lot sharper than normal, it's because I took these with my brand-new Canon camera...before I realized the camera had a dead pixel. I had really bad luck with Canon cameras, I think I mentioned before that I got a brand new shiny Canon for my birthday, but then the button on top was broken. Then I exchanged it but the screen had a dead pixel. So, I'm still chugging along with my Kodak.
Also, I know I've broken my resolution of trying to post every day, but I've been swamped with midterns this past week. Expect a little bit more posting in the next couple of days before I have to study again.
