I got some good feedback from the last post and updated the script to export JPEG Stereo (JPS) and PNG Stereo (PNS, really.) This way you can convert your images into a single lossless image that you can pop into photoshop and adjust hsv/levels, etc.
import mpo mpo.makePNS('DSCF9463.MPO') #>>Saving image: DSCF9463.PNS #>>Save complete.
This is a super simple python script, no error padding. Also, keep in mind that coming from most modern camera rigs, you are saving like a 20-40 megapixel PNG compressed file here, wait until it says it is done saving, it may take a few seconds.
