I had the pleasure of using the Singh-Ray Filter 830 Infrared Filter during my recent photo tour to Ireland. It was great to get to play with the filter and use it in a variety of settings.
(Please see my previous posts on Singh-Ray Infrared Filters. Canon users need to use the 830. Nikon users can use either but Canon cameras need the 830.)
All the images below are 240 second exposures, ISO 400-800, and f/stop of f/9 to f/22. In my experimentation, I’ve learned that you start with one exposure as above. Take the photo and then check the histogram. More exposure is needed if the histogram doesn’t hit the right side. Less exposure is needed if the histogram spikes up the right side. Be prepared for some trial and error.
Please read my previous posts on using this filter. It is a great tool and could be just what you need to add a bit of creativity to your photography.
