# in this current directory
python steganography \
    --visible-path .images/Forests.jpg \
    --hidden-path .images/wildfire_768_60.jpg \
    --steganograph-path .images/steganograph.png; # note: it has to be a png so the lesser-significant pixels do not get messed up.

to get:

Note the drop in quality, because the lower pixels are used to disguise the hidden image.
