BEHIND THE LENS: Here is a “behind the lens” look at my setup for one of the early dawn images featured in my latest post.
For all the camera geeks out there, here is a breakdown of the EXIF data (of the published photo, not the one in this post):
ISO 100: This captures the maximum dynamic range possible with my DSLR. More importantly, keeping the ISO at this minimum setting allowed me to use a longer shutter speed (1/8s) to physically gather a larger amount of photons. It is this abundance of light that keeps the signal-to-noise ratio high, giving me the cleanest possible data to work with when bringing the CR2 file into Darktable. Yes, I could have bumped the ISO to 400 for a faster exposure, but since there was almost no wind, 1/8s was perfectly sufficient to keep the landscape sharp.
Aperture (f/11): This is the sweet spot for my EF 24-105mm f/4L lens. Shooting at f/11 provides an excellent depth of field, keeping the landscape crisp from the foreground all the way to the background, while safely avoiding the diffraction that can soften images at narrower apertures like f/16 or f/22.
