the traditional rule of thumb is to shoot no slower than the reciprocal of the lens focal length so 1/30th sec for a 28 mm lens, 1/60 for 50mm and 1/500 for a 300mm.

Steady shot is a form of Image stabilisation built into the camera, so that you can take pictures and not have to worry too much about camera shake. This is an especially good feature if you are shooting in low light conditions, and the camera is using a slow shutter speed...
Shutter speed is how fast your shutter opens and closes to take a picture on your camera. Shutter speed also has a lot to do with exposure. The higher the shutter speed (1/2000 example) the less light.
The use of a tripod does not relate or depend upon the choice of aperture. It depends on a relationship between the shutter speed, the lens focal length and your ability to hold a camera properly and steadily. The general rule of thumb is, use a tripod if the shutter speed is slower than one divided by the lens focal length so as not to induce camera shake. For example, if the focal length is 250 mm, the slowest safe shutter speed would be 1/250.
The ISO speed, shutter, and aperture are all interconnected. There is never necessarily one "correct" setting for all 3. However, if you're not shooting on a tripod, you probably want to set your shutter speed to 1/60 to reduce camera shake. To eliminate grain, you may want to keep your ISO below 400. It may be cloudy on a rainy day, so you may be able to shoot at f/8 or f/11. Of course, on most digital cameras you could select a shutter priority (meaning the camera will adjust the aperture for correct exposure at a shutter speed of 1/60) and then set your ISO to 400. The camera will automatically meter the scene and set the aperture correctly.
For Canon cameras 'IS' refers to "Image Stabilisation". Nikon have the same technology but they call it "VR" - "Vibration Reduction" and other manufacturers have different names for it but they all amount to the same thing. With some SLR camera manufactures the image stabilisation is built into the body of the camera but generally the IS is built into the lens. It reduces the effect of "camera shake" which can make your images blurry at lower shutter speeds.
To capture non-blurry pictures with your camera, ensure proper focus, use a fast shutter speed, stabilize your camera, and avoid camera shake.
By safe shutter, speed I assume you are wanting to know the slowest shutter speed that will not capture noticeable camera shake? There is no absolute answer to this. How much do your hands shake? The 'rule of thumb' I have used is 1/{focal length}. For a 400mm lens you would need a 1/400 sec or to use a tripod to avoid noticeable camera shake. For the 18mm you might get away with 1/20 or so. Although I despise using tripods, they will always give a sharper picture. You might need a microscope to tell, but you can tell.
To take a photo with a slow shutter speed, adjust your camera settings to a lower shutter speed, such as 1/30 or 1/15 of a second. This will allow more light to enter the camera, resulting in a longer exposure time and capturing motion blur in the photo. Use a tripod to prevent camera shake and ensure a clear image.
To take slow shutter speed photos effectively, use a tripod to keep the camera steady, set a low ISO to reduce noise, and use a remote shutter release or timer to minimize camera shake. Experiment with different shutter speeds to achieve the desired effect, such as capturing motion blur or light trails.
The minimum shutter speed required to avoid blur in photography depends on various factors such as focal length, camera shake, and subject movement. As a general rule, a shutter speed of 1/60th of a second or faster is often recommended to prevent blur from camera shake. However, for moving subjects or longer focal lengths, a faster shutter speed of 1/250th of a second or higher may be necessary to capture a sharp image.
To capture sharp and detailed photos using a fast shutter speed, adjust your camera settings to increase the shutter speed, use a tripod to minimize camera shake, and ensure proper focus on your subject. Additionally, consider using a higher ISO setting to compensate for the faster shutter speed in low light conditions.
The streaking is probably caused by the movement of the stars if you have a very slow shutter speed. ie. Because the earth is rotating enough during your long exposure that the starlight makes the "trail".Another factor could be that the you may need to use a remote release for the Camera to ensure you do not have any inadvertent camera shake when you press the shutter._______________________________________________________________________The dude above is right. The motion of the stars would cause the blurred effect. However it is more logical to assume his latter explanation. When you take the photo, actually pressing the shutter button causes enough vibration to slightly distort the picture.A simple way to avoid this is to use a timer, set the time to about 2 seconds press the shutter and get out of the way so the camera won't shake. I had the same problem but I used that idea to save me.
An electronic shutter in a digital camera is a mechanism that controls the exposure time of the image sensor electronically, without any physical movement. This differs from a mechanical shutter, which physically opens and closes to control the exposure time. Electronic shutters are typically faster and quieter than mechanical shutters, allowing for more precise control over exposure and reducing the risk of camera shake.
Using a digital camera with remote shutter release allows photographers to take photos without physically touching the camera, resulting in sharper images by reducing camera shake. This setup also enables photographers to take self-portraits, capture wildlife without disturbing them, and shoot long exposure photos with precision.
Your pictures may be coming out blurry due to a few reasons, such as camera shake, improper focus, low light conditions, or a slow shutter speed. Try stabilizing your camera, adjusting the focus, using a tripod, increasing the light, or adjusting the shutter speed to improve picture clarity.
