comment How to fill my time-lapse video with more frames?
Let us know how that affects battery life! I would guess that it more than doubles the battery life, since the camera also has to process (subtract) the dark frames it takes. If it does, one spare battery would get you up to a 24-second video, or maybe a bit longer if you keep charging batteries when you take them out (though I think the AC adapter kit is still a better idea, and maybe worth the $50 for your use case).

Wow, 10-14 second seems like a very long time. Are you sure you don't have dark frame subtraction (chdk.wikia.com/wiki/CHDK_User_Manual#Dark_Frame_Subtraction) turned on (it doesn't sound like it, because DFS time should match exposure time, but I don't understand what else could cause a 10+ second delay)? If you do, just turn it off, take one dark frame photo when you're done (cover the lens with a hat; do it last so the hot pixels will all have finished warming up), and subtract the dark frame with software.

Why the 10 second processing time? Can you speed that up, e.g. with a faster memory card? Why the 2 hour limit? Can you increase that with a better battery or an external power supply? Do you really need 30 photos/second? Have you tried 10? How long of a video do you want when you're done? 16 seconds, 16 minutes...?

comment What is something you learned recently about your gear that you wish you discovered earlier?
30D doesn't have LiveView. But that will be a nice feature when I eventually get a new camera. If they're so incomplete, why do DSLRs bother with glass, instead of electronic, viewfinders? ;)

comment What is the best lens for taking photos of birds?
@Nathan that's a 4x zoom (400/100=4). "Zoom" on a lens is the difference between the longest and shortest focal lengths. When comparing lenses, you generally want to compare focal lengths, not zoom values. When choosing a lens to mount on your 60D, multiply its focal length(s) by 1.6 and see where that value slots in to the 28-504 of your DMC-FZ18. So a 100-400 would be "like" (there are a lot of other factors, too, it's not just a simple multiplication) a 160-640. It would reach longer than your DMC-FZ18, but zoomed all the way out would be like zooming in 5.7x on your DMC-FZ18.

Okay, that appears to have a 28-504mm (35mm equivalent) lens; 504/1.6=315, so a 300mm lens would have just slightly less reach than you're used to.

Yes, that's the right lens.

"both are way below the Canon" --> you meant "Nikon," right?

comment How to get started with fashion photography?
+1 for emphasizing practice. Taking a training class with a professional model and professional photographer to impart advice might not hurt, either.

I'm curious. What exactly do you mean by this? Can you post an example picture or two?

comment What can you do with embedded GPS locally?
Thanks, that showed me what I was doing wrong (the calculation is /60/60 for seconds instead of *.01/60).

comment What can you do with embedded GPS locally?
I looked at the exif data, and it says Latitude is "45.00, 30.00, 32.27" and Longitude is "73.00, 33.00, 6.77" (other fields indicate N and W). 45+30/60+.01*32.27/60=45.505378. 73+33/60+.01*6.77/60=73.551128. I plugged 45.505378, -73.551128 into google maps, and looked up that building, and used the ruler tool (from labs) to measure from the point I calculated to the front of that building: got about 430 yards. I'm just guessing on those calculations, though, really; if you know of a more correct way to use those numbers I'd love to hear it.

comment What can you do with embedded GPS locally?
There is an EXIF tag in the file you shared labelled "Direction of movement" (0x000f) and it has a value of 94.41 (I assume that's in degrees, so East?). But that is certainly different that orientation! If its name accurately describes its behavior, it would only be useful if you take pictures pointed in the direction in which you were moving. There is also a tag "Orientation" and its value is "top - left" so I think that is more likely landscape vs. portrait. No EXIF tag includes "compass" in its label. You might try some experiments with 'exif -l' and 'exif -t 0x000f filename'

The location information appears to be off by about 430 yards. Is that typical accuracy for that camera? Is there a different (more accurate (I assume also more power-hungry)) GPS mode?
