I used to work a grave yard shift which starts at 4am so getting up is not a problem. But getting up for a hobby might be a bit more challenging. It's strange how we are motivated. Not problem to slave away in a job which pays minimum hourly rate, and we hate it but still doing to make a living. I got out after 7 months of grave yard shift. There must be a better way of earning a living was my reason for me to quit.
Getting up for the sunrise has it advantages as well. You drive to the location, not like stuck in traffic for rush hour work and basically crawl to work. An easy way to develop a heart condition with the modern lifestyle.
This particular morning I was very fortunate to witnessed a storm developing. The clouds and the lights just moved every seconds. I shoot time-lapse so you know it was beautiful, still using my Canon 7D at the time by the way. Some people reckon the time-lapse was short....that was meant to be like that, Time-lapse photography compressed time from say one hour to 15 seconds. See below for the time-lapse video. Please no not complain that is too short. I have learnt to combine time-lapse together but shooting time-lapse is challenging. Especially with the post-processing it.
