Healthy Vision - Day 121 #CY365 @ThisIsRobThomas

May's #CY365 theme is about vision. While today's cameras are quite remarkable at capturing what we see, their "vision" is not at all equal to our own eyes. Our eyes eye can actually perceive a greater dynamic range than is ordinarily possible with a camera. If we were to consider situations where our pupil opens and closes for varying light, our eyes can see over a range of nearly 24 f-stops while 8-12 f-stops is generally all one can expect from a digital camera. This is most evident in low light photography especially when bright highlights are present, such as a stage performance.

Tonight Cindy and I went to see Rob Thomas at the Durham Performing Arts Center. It was an intimate performance with just two musicians joining Rob Thomas on stage. The overall lighting was low but there was always a spotlight on the star. Even with spot metering enabled, my camera struggled to get the low light background exposed, resulting in an sharply overexposed star. Manual exposure or severe exposure composition is the only way to capture the scene and avoid blown-out highlights. Since the camera can only capture a limited dynamic range, much of the scene is underexposed. So every picture is a trade off, while our eyes make the adjustments consistently and our brains composite the image so we see much more. And yes, the show was amazing. Canon G15, 1/80 sec @ f/2.8, ISO 1600.

Uplifting - Day 120 of 365 #CY365

I love watching the ferns come back to life in the Spring. They sprout new stems and uncurl the beautiful leaves from a tightly wound center, one of the many uplifting signs of Spring. Canon 5D Mark II, 1/160th sec @ f/11.0, ISO 1600, 100mm macro.

Lego Buzz - Day 119 #CY365

Creating a little "buzz" with the Lego man. iPhone, Camera+ App

Four - Day 118 #CY365

The number four is represented in binary as 0100. I created a batch file to produce a "Matrix digital rain" like display on my computer screen and then captured it with my iPhone using the Camera+ app. I then applied a square crop, the Clarity effect and the So Elmo filter to get the final image. Anyone care to guess how many "fours" are in the photo?

Square - Day 117 #CY365

Today's challenge was "Square", as in a square crop - a la Instagram, with a focus on the rule of thirds for composition. So a triangle inside a square crop seemed be the answer for me. iPhone 5s using Instagram with the Sutro filter applied.

Colorado Blue Columbine - Day 116 #CY365

Our Colorado Blue Columbine has a night visitor. The little spiders are everywhere tonight. Almost every bloom I looked at across the yard had the busy little spiders working away. Canon 5D Mark II 1/160 sec @ f/11, ISO 1600, two LED light panels.

At Last! - Day 115 #CY365

Spring is here at last. Several weeks late this year but the strawberries are blooming, so ripe bright red berries can't be too far away. Canon G15, 1/500 sec @ f/3.2, ISO 200 in macro mode.
