Andy,
I'd be happy to post a detailed report. First off, I had a good time and would recommend Joe's workshops. Especially one in the DC/Md area since that's definitely his home territory.
This was a two day workshop in the Delaware Water Gap recreational area. There were 4 other participants in the group, ranging from novice to fairly advanced amateurs. The plan was to shoot waterfalls, wildflowers, the Delaware River at sunrise, some old barns, and a lake at sunrise/sunset. The weather for most of the weekend was overcast and sometimes drizzly. So the sunrises and sunsets were duds, but the weather was perfect for waterfalls.
We met up at 6 am for sunrise at Hidden Lake. It was probably a great spot, but as I said the light was not happening. We went on to shoot 3 waterfalls (Childs Park, Dingmans Falls, Buttermilk Falls) and an old abandoned barn that day. For sunset we returned to Hidden Lake which was again a dud due to drab lighting. But shooting the waterfalls was great, especially at Childs Park. I think Joe's specialty is waterfalls, so if that interests you, you can really learn a lot from him. He's willing to get wet to get the best angle, so if you're up for that it can be a lot of fun. Some in the group were, and some were not. It was definitely a full day and everyone was pretty tired by the end.
The second day we had another sunrise at Hidden Lake. Again, not much happening. So we went to explore a stream with several sets of waterfalls. This was a fun and pretty vigorous hike. It didn't yield many great shots for me though since the best falls were located in gorges that were too steep to descend.
We spent the afternoon in a local library while Joe taught us some stuff in Photoshop. The primary things he taught us were 1) using layers to blend two exposures. He uses this technique a lot on waterfalls since the flowing water is usually much brighter than the rest of the scene. So he'll take two shots, one light and one dark, of a waterfall and then blend them.
2) A quick HDR tutorial using images of the barn we shot the day before. Joe's not a big HDR guy but this is a hot topic and is definitely an interesting technique.
3) Dodging/burning/vignetting to keep the viewer's eye trained where you want it to go. Joe kept it pretty simple and, even though I don't use Photoshop (I use GIMP or Corel Paint Shop Photo X2), I'm able to apply the same concepts.
In the field he taught how to use polarizers and graduated neutral density filters, how to use the histogram, setting focus with live view, and taught me how to use my new macro lens. He would also find some compositions and help the participants set them up. Joe is a pretty laid back guy. I think his style can suit both people who 1) have a lot of questions or 2) want to be left alone more. He'll answer questions patiently all day but most of the time he isn't actively teaching. A few times a day he'll bring up a topic himself and explain it, but most of the time he answers questions as they arise. It was also just enjoyable hanging out with friendly, like-minded people, since usually photography is a solo activity for me.
Here are a few of my favorites that I took from the workshop. Actually the sunset was taken the night before but whatever.
The best waterfalls were at Childs Park. The falls are beautiful and very easily accessible. I highly recommend checking it out if you're in the area.
