I don't know if anyone else has a attempted or has a 365 project running but since I have one well on its way, I thought I'd share some thoughts about it.
First of all, on how I got started. I have no fancy story about this. I simply decided one day to try. I didn't really even have a serious intention to finish it. As it was just something I did on a whim the starting date was a bit less conventional (April 10th), most of these projects starting on January 1st. Part of the motivation was moving to a less familiar camera system as I moved from Canon DSLR to an Olympus µ4/3 and I wanted to thoroughly familiarize myself with it.
As an experience it's a bit hard to summarize it. I can honestly say that I've taken some of my favorite photographs during this project as well as some of my least favorites. Sometimes inspiration comes out of nowhere and sometimes other things take precedence and I've found myself desperately trying to come up with something to shoot at 11:30pm. Sometimes I've found myself well prepared and having more than adequate time for a photography session and the results are crap none the less. So has my quality remained constant. Absolutely not.
Would I recommend starting one? Absolutely yes! I've grown much as a photographer and as an observer of my surroundings during this project. It may show in the pictures only very intermittently but I have done some commissioned projects during the project and the experience gained during the project has been very valuable. Foremost I've learned to be more alert and quicker to respond to an opportunity. Lesson learned mostly with my adventures in the mysterious and fascinating world of street photography. Stealth has been one other of the valuable lessons learned during those adventures. Regardless of the fact that it's a major undertaking which if you have personalty like me will give you more grief than pleasure, I wholeheartedly recommend it. It's a few minutes of your day for a year and you'll learn things about yourself and your photography that you didn't think existed.
To summarize. My word of advice to anyone who's thinking about it. Don't think, just do it. Take it one day at the time and don't expect too much. Getting that masterpiece of photograph every day is a goal you'll probably never be able to reach and constantly being disappointed of your performance will kill your motivation quickly. Take it as it comes and don't look back. Don't try to reach the end but instead set some kind of milestones you at least want to reach. When I started my first was making it through the first month, then making it to triple digits, then half way and as a result I'm now on my 280th day. Now I have no excuse not to finish.
I have to level with you 365 project will not be always fun and it is mentally consuming but when everything falls into place it can be hugely rewarding. Some days you'll end up with dozens of good photos. Finally, carry your camera with you all the times, chances are your daily photo will find you without you having to go out to look for it. Then do some planned stuff every now and then for a change of pace.
If you're interested in starting a 365 project and have any questions about it, don't hesitate to ask. It'll be my pleasure to help you get or keep going if I in any way can.
If you're interested in following my progress I try to post photos in my
