I've seen a few photos like this on flickr, and I have been wanting to try one.
This was a lot of fun to do, especially listening to my daughter giggling as I struck each pose. Patty was nice enough to take all the pictures. Although you only see 10 of me, there were 13 shots taken, its just that the me at the front of the car and the me at the back of the car are blocking the view of three other me's in the background. But ten Chucks isn't bad for a first effort. And I learned a couple things along the way (beyond the obvious: plan out the shot!)
One is, even with the camera on the tripod, it still moves a teensy bit with each shot. I really should have set up the cable release for Pat. Next time we try this, I will. The other thing is whenever I've seen this shot done, the photographer tries hard not to have anything in the picture that moves… like say a car. When I sit in the front seat, she leans a little forward, when I sit in the backseat, she leans a little back, and so on, each tiny movement creating seams and edges that don't line up as I try to stitch things together. So either I should leave the car out of the shot, or put sandbags in the front and back as I move about to even out the weight.
But still it was a lot of fun and I liked the end result. Y'know when I look at Vanessa, many thoughts cross my mind. “Clown Car” isn't one of them. 
As I said on Flickr, this photo is amazing and an instant favorite. My son and husband want to try something similar. I'm definitely linking to this one.
It turned out quite well. I may have to try something like this.
The closest thing I've done is Applying Snow: http://www.deviantart.com/deviation/53392547/
I also enlisted my daughter–not to take the picture, but to stand on one end of the seesaw when the snow had melted.
It was difficult to stitch two pictures together, I can't even imagine 10+.
Chuck…. there are posts on your blog!
I love this picture!!
Thanks Maggie! I had a lot of fun doing it. Using a camera with a timer, one could even do it oneself, although it was a lot easier with Patty manning the shutter.
Yes, posts on my blog, isn't it amazing? Hoodathunkit?
Bolty, I love that picture! What a great shot!
In all likelihood yours was more difficult to put together. These 10-13 shots were all taken with the same perspective, from the same spot, at the same height, same shutter speed, etc. over a period of maybe 20 minutes. In your case the two photos were probably taken months apart, and unless you let the camera sit on a tripod for 6 months, you probably didn't have the same perspective. I'm very impressed with your applying snow picture… good job!
Heh. Yeah, the shots were about 2 months apart. And, no I didn't use a tripod for either one. In fact, the second (clear) shot was set up quickly from memory–”I think I was standing about here… quick! go stand on that end of the seesaw before your mother is ready to go to work…” *snap* and it was done.
I had to resize and realign the picture in Paint.NET. To do this easily, I adjusted down the opacity of the top layer so I could see both at the same time.
I wish I had more time for photography. It looks like you're having a blast!
Boltbait, that's amazing! I love it!
I posted this photo to my employer's internal website and won $100 for the most popular submission for July! Yay!
I'm not surprised! That's awesome!!
Wow. That borders on caring about employee morale…
I have a feeling that other people are going to have trouble topping that in the upcoming months.
