Have you ever looked at the price of most photo workshops, including the ones in the United States, and gasped at how expensive they are. $1500-$2000 for Death Valley, $1800-$2200 for the Olympic National Park, $2300 for the Badlands, $1200-$2200 for Vermont, $4000 for Wyoming, $3500 for Utah and don't even think about foreign trips unless you have two mortgage down payments saved and that cost doesn't even pay for air fare. In fact none of the workshops cover transportation costs or for that matter food!
I know that the higher costs is for being able to share and absorb the superior photographic knowledge and technique that would be on display but this is not 30 years ago when the internet was just being introduced. There is some much photographic information on the internet and some very useful books and e-books that you could purchase for a nominal fee. There are also very well presented video courses to purchase under $200 that would provide the basic photographic foundation for your own creative pursuits. The pursuit of photographic knowledge on your own and the discovery of techniques essential to your own creative development will create a stronger sense of artistic self worth and the pursuit itself can be so enjoyable in expanding your interests and knowledge. There will always be detours and tangents away from the original pursuit which could result in new and exciting discoveries that you did not even think about yet. Attending a workshop, you are limiting yourself to a general presentation with limited individual support. This creates an artistic conformity that you should avoid. And if you do not think this leads to artistic conformity, look at photographs of the workshops out in the field where everyone is crowded around the same viewpoint crowded within small feet of each other. You will be intimidated to pursue a viewpoint contrary to the whims of the workshop projections. Individuality is crushed with this workshop objective. Maybe the pursuit should be your own and your own only!
Instead of going to a photo workshop, determine what you want to photograph and if you want to photograph landscapes plan your own creative trips. Invest in your own accommodations. A recreational vehicle is very expensive and has pretty poor gas mileage. There are specialized 4 wheel drive vans and trucks that are custom made for exploration but again pretty expensive. Four wheel drive truck with a camper top is a good alternative but if you want to sleep outside, a good quality tent is something to invest in. I had for years a Cabela's Alaska tent which was the 6 person tent but Cabela's merger with Bass Pro Shops has been a disaster not only for Cabela's but for Sidney, NE which was the headquarters of Cabela's. The new versions of the Alaska tent have fiberglass poles instead of aluminum poles which really reduce the strength of poles. My wife and I really wanted something bigger that you could walk all around the inside and we decided on a canvas tent and we bought a Springbar tent. But their quality of workmanship has slipped in the past couple of years with complaints of very poor service and the Kodiak tents would be the better option. Kodiak is a Chinese copy of Springbar but the tent material is sourced in the United States and assembled in China and the Springbar tent material is sourced from foreign sources and assembled here in the US. Our Springbar tent has gone through F1 tornadoes, 80 miles per hour straight line winds, 8 inches of rains in 20 hours and still standing tall. A canvas tent will give you an excellent base camp to discover landscape photographic opportunities. Your savings from not attending a photo workshop will allow you to set up a basecamp operation that will last for a very long time.
What I am expressing is to point a direction towards your own vision, your own discovery of outstanding photo opportunities, your own freedom of creative endeavor and the strong satisfaction of a job well done only by you. Trial and error will lead you to discover your true creative path and to really enjoy the journey to that path. This will not be a journey purchased for your immediate gratification and whims, but a journey undertaken by yourself with planning developing your own direction.
