Blur and Shutter Speed I have a Sony Cyber-shot DSC-P200. It's 35mm equavalent focal length is 38 - 114 mm. I know the usual rule about having a shutter speed the same as your focal length; however, in some photography books I'm reading they always recommend a tripod. Does this recommendation apply for daytime shots too? What is the shutter speed "limit" on non-blury photographs when hand holding a camera?

Someone correct me if I'm wrong (and I'm sure you will, LOL) but the slowest "acceptable" shutter speed for handheld shots is 1 over whatever the focal length is. So, for my f/2.8 60mm lens, the slowest I would want to shoot would be 1/60 of a second (1/60"). Hope this helps.

hey matthew, many things; lens speed iso setting amount of light/shutter speed caffeine you could brace yourself on a pole or wall for better results also. and a tripod without using a self timer or remote release isn't much better. is the subject moving? hth,sam

The ISO is usually 100 and the subject is still.

It's a pretty individual thing: some people are steadier than others, so the "rule" of 1/focal length is a rule of thumb, only. If you are using a digital camera, it's 1/(35mm equivalent) focal length. The rule is really only good for "normal" focus situations. Get into close focus or macro range, and the depth of focus becomes so shallow that the wise will opt for any extra support they can get...tripod, monopod, beanbag, wall... There are other reasons for using a tripod: it slows down the work flow, requiring a different attitude to your subject; it allows you to walk around your subject, move away from the narrow angle of view and consider the subject in context, fire the shutter with a remote or cable release while remaining engaged with the subject... many reasons.

Oh, okay. So depth of focus leads itself to possible blur, but for the same reason? Is it due to camera shake or due to that if you shake the camera, your "plane" of focus will shift and the wrong part of the image will be in focus?

let's see. camera shake is camera shake.with macro and long telephoto shots camera shake is magnified.some squeeze the shutter button and some snap. then if you can set your aperture to 1.7 and let in a lot of light,bump your iso up to 400,which will set a faster shutter speed you could handhold with better results. I shot a 6th grade football game from outside the field at 300mm,iso 400,f5.6 with excellent results.sharp and clear,you can read their names on a 4x6 print.i braced myself mainly on the light poles. and yes depth of focus is so narrow in macro shots any movement will change where the focus actually will be. hth,sam
