When you take an image in low light, may some people interpret it as ';not clear'; or ';blurry';?

maybe they just don't like the real lighting conditions for an image...maybe the image had lots of noise since it was taken at a high ISO. maybe they're used to clarity of an image when a flash goes off. what do you think? thanks.When you take an image in low light, may some people interpret it as ';not clear'; or ';blurry';?
Facts of life. Higher ISO means a more grainy look. Less light means more movement is being photographed as the shutter will stay open longer.





Indeed both 'effects' may be seen as blurry but it is a clear winner when competing with all over white flash atmosphere killer.When you take an image in low light, may some people interpret it as ';not clear'; or ';blurry';?
In some circumstances, I like superb clarity and sharpness. Sharpness is not everything, however.


In many instances, I much prefer the IMperfect light and the resultant graininess, even a slight degree of blur.


In some circumstances, this is what creates extra ambience.


Example #1 is 1/30th handheld in what I thought was good light, coming through the kitchen window. Even at that slow shutter speed, reasonable sharpness and that is really what was needed for this.

Example #2 was in poor light and the ISO was raised. Still 1/30th sec but the noise is so much more apparent.

The question is ... does it matter?


If a viewer cannot see past a need for technical excellence


and grasp the emotion presented, I do feel sorry for them.


Agreed that technical excellence is DEMANDED in many instances but, look at this one and tell me that you want better light and better clarity?

Why would one?


Is it 'not clear' or 'blurry'? So what. The end result is exactly what I want.
I have a photo of my grandson taken indoors. I absentmindedly pushed the flash window down, so it was taken in indoor lighting. The result is grainy but is more interesting and arty than the usual photo taken with flash.
The main problems relating to blurred images caused by low light are camera shake and poor focusing.





The focusing systems can struggle to pin point the area of focus desired by the photographer in low lighting and lower shutter speeds make burring caused by inadvertent hand movement more likely.





This may be mistaken for noise from time to time but the clarity issues are usually caused by the above technical problems.





The solutions are to focus manually; or to be more careful about getting the point of focus right; to choose higher shutter speeds (possibly requiring higher ISO settings) or to take more care not to move the camera while shooting; or to remove noise that detracts from the image by post processing filters such as Noise Ninja.
Low light could make an image blurry, unless you have light on the right plces, like the thing you are actually taking the picture of
