Sunset on Mono Lake
Posted by Doug Otto in Photography on October 5, 2009
Mono Lake is one of the most photographed subjects in the Eastern Sierra, and for good reason. The placement of the lake often brings very interesting cloud formations that mix nicely with the otherworldly appearing tufa. On this particular evening that wasn’t the case.
We arrived at Mono Lake shortly before sunset and were greeted by blank blue skies. Thankfully, after the sun had slipped behind the Sierra’s some faint color started to appear in the Eastern sky. It was very faint, so I chose to use a very long shutter speed to capture the color. I set my f/stop to 16 and adjusted the shutter speed until I was happy with the exposure. Next I attached my 10 stop neutral density filter on the lens, being careful not to change the focal length. I entered the original shutter speed into Filter Calc and computed a shutter speed of 74 seconds. The extra long shutter speed completely smoothed the surface of the lake making the scene seem even more alien. I liked how the foreground rocks mimic the shape of the tufa.
Cheers
Stayed Tuned for Filter Calc – Now Available

Announcing Filter Calc. Filter Calc is a simple application that I wrote for my iPhone. Neutral density filters are a fun way to do some really long exposures. The caveat is that once you get past 30 seconds, most cameras are unable to give you the correct exposure value.
Enter Filter Calc.
Click to Enlarge
The premise is pretty simple:
1. Meter the scene without the filter.
2. Enter the filter type and shutter speed into Filter Calc.
3. Read the corrected shutter speed.
4. Install the filter and take the shot using the corrected speed.
Filter Calc should be available in the iTunes App store shortly and will be offered, initially, at no charge.
There is a ton of potential for photography applications and I’ve already mentioned that I’m a big fan of Focalware. It just goes to show you that there’s nothing wrong with being a geek.
The typo on the main page as already been fixed and will appear in the next update.
