Night/Low Light Photos
These types of photos really present a challenge. The challenge increases when you take a night or low light photo without flash.
Please feel free to add your night and low light photos. Of course, include any shooting tips that work well for you. Ask questions and maybe someone might know the answer.
This is a learning blog so let's learn about photography. It's also a place you can show pictures you have taken and like.
Peace from the blog porch, Gardengrrl
Here are some of the picts from the festival. What is amazing about these art pieces is that nearly every one is made of various silks stretched over frames with lights woven inside and out to make them glow or blink.
These were taken with my "bridge camera" a Fuji HS20 using the sports mode and E/V dial to lower the exposure from the bright light dark background.
From the last blog, I imported some great info to help improve your photography provided by Sandi. And yes, this info applies to point n shoots as well.

Here is a tutorial on F stops and apertures, and why "bigger is smaller"!
Exposure 0.006 sec (1/160)
Focal Length 159 mm
ISO Speed 400
When looking for a simple example of ISO related to aperture / F stops I found this. And rather than pick out examples, I think it warrants an airing here, as it is fairly clear and precise - so I hope you don't mind!
ISO - is the sensitiviity of the sensor to light - higher the ISO the more sensitive so the less light to record the photo
Aperture - the size of the hole that lets in the light. Larger the hole to more light gets through. Expressed as the a fraction of the focal length - so f/22 is 1/22nd of the focal length. This means the larger the number the smaller the hole.
Shutter speed - length of time the shutter is open. The longer it is open the more light gets in. Expressed as fraction - 125 = 1/125th of a second. Can be confusing when you see the number "8" - is this 8 seconds or 1/8th - you need to be clear in your own mind how your camera
Fast shutter speed freezes motion (including camera shake)
Long shutter speed increases motion blur
Small aperture gives high depth of field
Wide aperture gives shallow depth of field
Depth of field is the amount of the shot that is in focus. For example, shallow depth of field - person is in focus but background is blurred. High depth of field - person is in focus and so is background.
You balance shutter speed and aperture to give the optimum combination of motion freezing and depth of field.
Low ISO gives best quality image but needs a large lump of light
High ISO makes the image grainy (noise) but needs a smaller lump of light.
In low light you may need to increase ISO to make the required lump of light small enough to allow use of a shutter speed that you can hand-hold.
