Very little post processing is needed. With the color image, I used Viveza in select areas for color and contrast adjustments, and darkening an area on the dock. I also like using Pro Contrast in Nik Color Efex Pro. The ability to control highlights and shadows is very helpful. For the black and white image, I used Nik Silver Efex Pro, starting from one of my favorite presets Full Dynamic for conversion, and fine tuning the adjustments from there.
Some of my BetterPhoto.com students are asking if I'll be writing a course on long exposure techniques, or doing a workshop. The answer is YES! This will be a lot of fun and we could incorporate a few other ideas such as balancing light using neutral density filters, photographing stars, star trails, capturing taillight streaks from passing cars, and photographing beautiful nightscapes. We won't be limited to just low light shooting. The images above were taken in the middle of the day. If you have any ideas on topics regarding long exposure techniques you'd like to see in class, let me know what your interests are in the comments section, or drop me an email. You can reach me on Facebook and Google+ too!
Strike Finder during a big summer storm yesterday. It works fairly well, we had some intense lightning over the course of several hours, close and very loud! Try this with your iPhone, and use MK Controls Lightning Trigger for high quality imagery of captured lightning. Have fun shooting! ~ Deb
