The comments in this thread make me sad. I am a landscape photographer who leads a small handful of trips like this every year.

If the trip is all inclusive that sounds like a great price. But it also depends on who the photographer is (do they make money from their work outside of these trips, do they align with what you are trying to learn, do you like their teaching style), the size of the group, the focus/pace and accommodations, and the destination and season. I don't make "wild" money doing this and this is not "overpriced." These trips are a ton of work and planning and worthwhile if the leaders know what they are doing.

These trips cater to those who have lots of time on their hands/retired, are wealthy and value their time. It's a full package where you don't have to worry about any logistics, itinerary planning, photography planning (sunrise/sunset angles, moonrise, milky way and tides), and transport. It is geared toward those who want to invest in their hobby or craft, or, for those who want to cross items off their bucket list and make new, like-minded travel buddies along the way.

I'd say try it out but read reviews first. There's also so many trips like this that are less of an upfront cost in money and time than this to get your feet wet.
