Blurry vs. Flash

<< < (3/4) > >>

McTaggart:
The guide I use is 1/focal length. With a 300mm lens any small motions you make in that 300th of a second still show up a whole heap because of the small angle that you're getting on the sensor. Longer times for shorter focal lengths (wider angles). This kinda breaks down a bit when you start changing the size of the film/sensor, and the size of the film also changes the field of view so it ends up being pretty close to 1/(the 35mm equivalent of the focal length). So about 1/50 for normal, 1/30 for wide angle and 1/90 for zoomed in.

Edit: Get a tripod though. A good tripod is right up there with the smell just after rain and the feeling when you've just driven to work (right by the beach) at 10 am and it's a warm, clear windstill day and they say "We really don't need you today, it's gonna be quiet" and you have your boardies and towel right there in the car.

on most digital cameras you can change the ISO, put it up around 4-800 and you'll get better results. 

McTaggart:
You also get orders of magnitude more noise which might play hell with the filter he's using for his comic. If you run the images through NoiseNinja or something like it you can probably get it to play nicely.

Unless you like digital noise, which I kinda do (real digital noise though, not the photoshop noise filter).

bujiatang:
we haven't talked at all about changign the aperature... something like f3 might help.  I love the 80mm lens for my mamiya b/c I can go to f1.8

IronOxide:
If you can't do a tripod, the best idea is to find places with good lighting and leave the aperture wide open.
