I have done a LOT of reading and searching so far - and I am sure there is still plenty more to read. And plenty time needed to save - if
Trips for photographers specifically is available - but as said - hellishly expensive.
BUT It would be a trip of a life timePeculiar that most of the photographer trips I found, are run by South Africa based Tour groups - by photographers themselves
One has to be careful not to join a boat like Akademik Sergey Vavilov (ONE OCEAN) - it appears you join the whole bloody ship and the tour leader (a photographer from SA) books only some spots, (eg 10) and one zodiac is allocated to that group specifically. They kind of give extra attention to the photographers, but not so much that you would notice
Prices range from here to eternity on these trips.
However - there are tours that are photo specific, see attachment for an example of what is on offer. Its just one of the tours so you can see how it works.
so you basically go on a boat trip. Why not book our own boat - no need to pay for the tour group photographers trip and plane ticket?? We have one another !
then there is JOshua Holko - which I think chased bears (POLAR variety) in a big way and I would kill to go with him

ORYX is NOT recommended (thats the one you join the rest of the world on one ship)
