I'm fairly new to QGIS/GIS stuff in general, so I apologize if this is too simple of a question, and I'm just bad at finding my answer.

I have a shapefile of all the countries in the globe I downloaded from Natural Earth. I'm needing to create two hemisphere maps (similar to these guys I found on Wikimedia) in a azimuthal equidistant projection: enter image description here
However, I need the western hemisphere to have most of Europe and the US and the Eastern projection to include Asia and Australia. Basically, the center of the map would be the middle of the Atlantic.

I narrowed down the problem to it's my proj language in the CRS, but I'm not sure how to pair the project to a circle.

Any insights for a newb?

To get am Azimuthal Equidistant map, follow my answer here:

Manipulating Azimuthal Equidistant Projections in QGIS

But that gives you an image of the whole world. You have to crop that picture to a circle around the point of origin in a second step.

But I'm not sure if you do not rather want an orthographic map:

http://commons.wikimedia.org/wiki/Grey-green_orthographic_projections_maps

This is what you get with

+proj=ortho  +R=6371000 +lat_0=0 +lon_0=7

That is a better projection. But it seems like maybe I didn't know as much as I thought I did. I created a custom projection and pasted in the code you gave, but my map is still linear and not rounded into a circle. Is there a step before the custom projection I've missed? –  Jessica Aug 29 '13 at 20:12
    
Most probably you have missed to hit the save icon in the custom projection dialogue. Then you can set the project CRS to that custom projection. –  Andre Joost Aug 30 '13 at 3:53
    
I finally got it to work! Thanks so much for you help. I figured out that I was importing the map in the wrong step of the process, so it wasn't applying the project at all. Thanks again for helping! –  Jessica Aug 30 '13 at 14:48
