Awesome!

The downsample parameter specifies the number of times to downsample the image by a factor of 2 along each axis ([this is documented here](https://allensdk.readthedocs.io/en/latest/_static/examples/nb/image_download.html#Downloading-a-single-Mouse-Brain-Section-image)). If you want a full-size image you need to set downsample=0 (watch out - these can end up being pretty big).

EDIT: download -\> downsample
