Clouds

About 40 min­utes of the clouds to the east of town. Enjoy!

Nerdy details

aka notes to self, for later

Pho­tos tak­en at var­i­ous expo­sures (1/1600s to 1/3200s), 11mm f/2.8, 24mm f/2.8, and 50mm f/1.8. The lens­es all had cir­cu­lar polar­iz­ers over them, to add dra­ma to the clouds, at least in theory.

Once I got home, I shrank the images to 3000×2000 pix­els using Imag­ick, dark­ened the 11mm ones (the expo­sure was a bit too bright) also using Imag­ick, and then used mencoder on the com­mand line to build the ini­tial timelapses.

Turns out Open­Shot, the pro­gram I want­ed to use to con­cate­nate the three time­laps­es into one can’t import the AVI files that mencoder made, so I con­vert­ed them to MP4 files using ffmpeg (the com­mand was ffmpeg -i infile.avi ouput.mp4, which seems too sim­ple to be true, but is in fact cor­rect). I import­ed the result­ing .mp4 files to Open­Shot, added the fade in/out tran­si­tion, and export­ed the movie.

Et hop, a 40-sec­ond video that took, like, two and a half hours of my life. (And I could­n’t be both­ered to add a soundtrack.) 

Inter­est­ed in prints of my pho­tos? Let me know, and we can work some­thing out.
