comment Canon Rebel XT - do electronic shutter instead of mechanical?
I wrote an application for my camera phone and while it works, but it isn't stable. The drivers I based it off of are still beta and crash periodically. The good news with it though is, it is perfectly silent, you cannot tell pictures are being taken so it does not annoy people. I'm trying to get my point and shoot working with CHDK and have limited success with it so far.

I shot more sample time lapses with a 1/2 second exposure with a 2 second interval (1.5 seconds after accounting for the exposure) and I like the smoothness of the pictures / video produced. Taking pictures with an SLR and an intervalometer was more than a little distracting, the sound of the shutter opening and closing ...

comment What are good exposure and timing choices for time lapse photography?
That is a good suggestion - instead of mounting it with the screen out, I would mount it with the screen in. I can then take pictures with it. It doesn't look very sturdy from the pictures though

@whuber, that's the thing though, eventually it will get compressed down to that. I see the value in taking all the pictures, as someone said, you can always go down, but you cannot go up. The real art of it will be sorting out which frames to keep, and which frames to skip.

Yes, the n900 is a smartphone. The primary body is plastic, it has a slide out keyboard. I looked at a gorilla grip a little, but am skeptical with it. They have an adhesive mount, but I don't really like that option. This is the closest I found: nokia-n900.com/store/…

@Rob Clement - your tips are all meaningful, this is why I am leaning towards using my n900. I can plug it into the car while driving (via USB / cigarette adapter) so I have power. Secondly, it has 48 GB of storage locally, and I can dump pictures while driving to my laptop via wireless (if I use USB, it will unmount the filesystem, so I won't be able to save pictures while it is mounted ...). So, the real problem at that point becomes, I don't have a good mount for the n900 nor a good time lapse application for it.

I am planning to stay at bed and breakfasts for most of the trip.

comment What are good exposure and timing choices for time lapse photography?
I was thinking about using my phone to take pictures. It has 32 GB storage plus an external 16 GB card. I can charge it when we're driving, download pictures wirelessly through an ad-hoc wireless network via ssh, and programmatically control the camera through scripts. The only problem I have now with that is, finding a good mount for the n900.

I was planning to mount the camera in the rear window looking forward or possibly the right rear window looking forward. I was thinking about putting up tint in the rear windows to hide the camera. Do you think that would be adequate to 'hide' it. Reminds me of the Jerry Seinfeld comment, putting sweaters over a tv, it's just a couple of sweaters with an antenna sticking out ...

@ysap, true, a neutral density is more appropriate, BUT I don't have one (even though I should). I am running my calculations again this time based on the limits of the hardware I currently have. Since I can't be swapping out memory cards all the time nor batteries, I have to use those as my guides too. My largest card is 4 GB, I have 2 batteries. I wonder if I can get 3k - 4k pictures on a single battery without autofocus?

I realize a 5 second exposure is long during the day, probably still outside of what a polarizer can bring down and a really small aperture.

I experimented with a drive around the block at 25 - 35 mph (210 seconds in 7 seconds). I shot at 1 fps (when the camera could keep up). It looked relatively smooth when played back at 30 fps.

I was going to shoot around the clock, at night, I was planning to lower the rate at which I take pictures to 1/10 of the day rate. I will also probably cut out boring stuff such as stopping for gas.

Good question, after doing my calculations, I think I want to do a 4 minute video at 30 fps (7200 frames). Does that mean I should shoot only 7200 frames, or take a bunch and let my stitcher 'blur' them?
