Some of us here are signed up for World Photo Day 2005 which is on June 1st. From their website, "The goal of the project is simple: to show the world we live in through the eyes of photographers, worldwide, on one day in the year 2005. This is in no way a contest. It is merely a platform for all to enjoy and review with pleasure". I see that Photography Review is also helping with promotional support - so here's a little more!
They're looking for images of people in their everyday lives and I've got a couple of ideas for environmental portraits. If the weather is bad, I'll have to go to plan B, for example - can't do it a couple days when the sky is better, etc! Part of the challenge is that you only get to submit one image, but you will retain the copyright to your work.
Note that the "Day" runs from midnight to midnight GMT (Greenwich Mean Time). You can check your local time against GMT here. I'm in the Central Time Zone so I guess that means that (since GMT is five hours ahead due to daylight savings time) I have from 7:00pm on the 5/31 until 6:59pm on 6/1. He's relying on honesty to make sure that people comply with this. If you're shooting digital he could check the EXIF data (hint: make sure your camera's date and time is set correctly) but I doubt he'll have time to do that. So let's keep it how he wants it, and work with the conditions you get - another part of the challenge! You can shoot film but will still have to send the shot in within 24 hours of the end of the day.
I'm signed up and know of a couple of others from two other past discussions we've had on the site. The day after the event, I'll start another "sticky" where we can all post the one shot we submitted - I'm excited to see what everyone comes up with. So who all is giving it a shot?
