I do not believe you can get the RAW information. I’m not that familiar with the RAW format or usage, but I do not see a setting for RAW format in the API. People have been experimenting with using the dual fisheye plugin from Ichi Hirota to produce HDR and tone-mapped images. Community member juantonto is taking some great shots using auto-merge of 3 to 5 images.
I don’t think the plug-in technology has the feature that you’re looking for. I have not experimented with the settings below.
