Bob as a fellow Parkinsons photographer I have some suggestions. First -please email me re: pros/cons DBS and some treatment options..discussion here is off topic. 2nd As another subscriber said--DO NOT give up. I do not have any idea how bad your tremor is or how effective the meds are in controlling the tremor.....suggestions need to be matched to your capabilities. A few one liners
1. use a remote all the time-wired or wireless..there are pros and cons to each (I assume the tremor is in your dominant hand
2. If you get excited (ie wildlife pix or a fading spectacular sunset) the tremor will be worse-use a remote!
3. Yes-you are now tethered to a tripod. I did not have good luck with a monopod
4. Ask your MD but beta blockers (used for stage fright) helps me some with #2
5. Depending on your arm strength (non tremor arm) I have some success holding the camera with one (left) hand and using a remote with the rt hand. Heavy tripods are limiting. Practice positions holding the camera to steady it (ie elbow on the chest--checkout pistol and rifle postures--ask for suggestions on steadying techniques). Obviously use image stabilized cameras/lenses
6. My landscapes are better because I spend more time with them now--wildlife shots can still be good (tripod) but you will have have fewer opportunities. (tripod set up)
7. Shoot flying birds with ball head or gimble set up and remote. Swing the camera ONLY with the left hand. It takes some practice but it works. SEE attached
8. I cannot solve shooting water birds form a boat, I built a platform for the tripod but the wave action overcomes the stabilizing efforts.

I was diagnosed in 2007. The tremor has NOT progressed...why is another topic. I had to learn to shoot my bow left handed (non tremor side)...took me 3 yrs but am now as good as rt handed. Do NOT quit photography or anything else --adapt! email me if you want , especially re: DBS jim.heywood@gmail.com

Bob, I am a neurologist and I see a large amount of PD patients with the majority continuing to be functional. Here are a few things: have your neurologist start Azilect (rasagiline) which MAY have some positive effects on delaying the progress (may because this was not FDA approved as an indication). Carbidopa/levodpa also known as Sinemet is the standard treatment but this is mainly to help you "move" only if you are very slow to move. I don't like to start it early especially if there is no indication for it. There are several options for tremor but as I am sure you know, the tremor is mostly resting and improves with action. I am sure your neurologist would talk to you about options to help with the tremor if it really causes problems. Most important: exercise like there is no end, have a positive attitude and keep on going. You CAN NOT give up photography, there are many solutions to problems but giving up something you like is not one of them. The exercise is either cardiac or resistance with weights and of course, better yet both. Tai-Chi is wonderful to help with balance.

Vermis, what a brilliant answer, especially sharing your expertise and emphasis on not giving up photography. Even though I do not have PD, I am thankful we have people like yourself, so willing to give of themselves.

Bob, keep on going and doing what you love. As you can see, there are options available for you to investigate with your neurologist. Take it from a Marine, there is no surrender when surrounded, simply charge in another direction. As to practical matters, if it should come to pass that tremors affect your photography, a tripod and electronic cable release will help immensely. Stay strong, get out there and photograph!
