Measuring the performance of DSLR cameras and why the ISO setting could impact the burst length.
Published January 25, 2012 | 
Today arrived the memory card i ordered for my smartphone (16GB Samsung essential micro SD ), so i got curious how it would do in my EOS600D. The speed tests with a card reader are not very representative for the real application, the card could perform good in the card reader but bad in the camera and vice versa. unfortunately, my camera doesn’t have a build in speed test, so I found another way to measure the real performance. The solution is to record the shutter sound!
I used the mic of the Logitech webcam (my usb microscope :) and Audacity (Free, Cross-Platform Sound Editor) for recording and analysis.
The results of different memory cards are not surprising, but i also tried different camera settings and was astonished about the significant burst rate drop on higher ISOs. The following tests are done in manual mode with manual focus and all the same settings with exception of ISO.

If you ever going to visit Hamburg, don’t miss the Harbor. I am planning at least another two photo sessions down there (sunset & sunrise).

Have you ever noticed that the negatives sounds so negative? :)

PWM Art

I’m working on my LED lightning system and took some photos of the RGB-Strips randomly changing colors. What i noticed is PWM-Signal visibility, you can recognize the duty cycle and even calculate the PWM-frequency(if you know the shutter speed). So your Camera is useful not only for documentation purposes but for debugging too :D P.S. Almost forgot the photographic aspect, randomly driven RGB-Stripes can produce very cool effects if you use them for light painting.
